NATIONAL WEATHER SUMMARY
MARCH 2007
1st-3rd...Rain and snow fell across the Northeast, parts of the Upper
Midwest and upper elevations in the Northwest on Friday. Most of the
precipitation tapered off in the Northeast by sunrise. In the
Southeast, a cold front pushed off the coast, ending the rain and
thunderstorms in the region. Snow and freezing rain fell in New
England, as well as in parts of the Upper Midwest and the Great Lakes
region. Rain and high elevation snow fell in the Northwest. The
Southeast rose into the 60s and 70s, while the Northeast saw afternoon
temperatures in the 30s and 40s. The Northern Plains rose into the
teens, 20s and 30s, while California saw temperatures in the 50s and
60s.
4th-10th...In the East on Monday, a clipper system brought snow to the
Northeast and eastern Great Lakes. Snowfall generally tapered off in
the Great Lakes, leaving 2 to 4 inches, with slightly higher amounts
continuing in the Northeast. In Watertown, New York, 4 inches fell,
with similar reports around the area. In some areas, high winds
combined with snow to create blizzard conditions, reducing
visibilities to less than a half-mile. Gusts up to 40 miles-per-hour
with heavy snowfall reduced the visibility to one-eighth of a mile. No
major problems were reported due to the dangerous conditions. Further
south, high pressure dominated the Southeast, Ohio and Tennessee
valleys, and the Mid-Atlantic states with clear to partly cloudy
skies. In the western two-thirds of the country, a weak storm system
brought scattered rain and mountain snow showers to the Pacific
Northwest, California and the Great Basin. Rainfall amounts were
generally less than a quarter-inch, with minimal snowfall amounts.
Otherwise, a strong ridge of high pressure dominated the Great Plains,
Mississippi Valley, the Rockies and the Desert Southwest, producing
clear to partly cloudy skies. Temperatures across the Central and
Southern Plains reached the 50's and 60's, while snowpack kept 20's
and 30's across the Northern Plains, with some areas in the teens and
single digits. The Rockies mainly stayed in the 30's and 40's, while
reaching the 60's in the Desert Southwest.
In the East on Wednesday, high pressure produced sunny skies and cold
temperatures across the Northeast and Great Lakes. Record low
temperatures were set in southern New York, Michigan, and on Long
Island. Skies were sunny over the Southeast, Mid-Atlantic, and Deep
South, but temperatures were more seasonal in those locations. High
clouds moved into the Ohio Valley ahead of a system, but no
precipitation occurred. Scattered snow showers developed across
Michigan throughout the day, and accumulations up to 3 inches were
reported. Across the central region, a disturbance brought scattered
snow showers to the Great Lakes, Upper Midwest, and Northern Plains.
Accumulations were light, with accumulations generally less than an
inch. 3 inches of snow fell in North Branch, Minnesota. Skies were
partly cloudy with dry conditions over the Central and Southern Plains
and Lower Mississippi Valley. High pressure brought partly cloudy to
mostly sunny skies to the West. A few high clouds moved across the
Desert Southwest into the central Rockies, but otherwise the region
was quiet, clear, and dry. Temperatures across the region were
generally at or above normal.
In the East on Friday, scattered rain showers and thunderstorms
developed off the Carolina coastline as a frontal boundary moved out
of the region. Rainfall amounts were light. Skies were partly cloudy
across the Southeast and Deep South. Further north, high pressure
controlled the region. Skies were sunny with dry conditions over the
Mid-Atlantic, Northeast, Appalachians, and Ohio Valley. Record low
temperatures were set during the morning hours in New England.
In the central region, a low pressure system moved through the Midwest
and lower Mississippi Valley region. Rainfall amounts were mainly less
than half an inch, and rain was reported from Wisconsin to Louisiana.
Severe thunderstorms developed during the late afternoon and evening
hours over the Ozarks and eastern Oklahoma. Hail was reported in
Kansas, Missouri, and Oklahoma. Flash flooding was a concern in Craig
County, Oklahoma as heavy rainfall was reported. Skies were partly
cloudy across southern Texas and also the Northern Plains. Over the
central and southern Plains, skies were sunny with dry conditions.
Over the West, a low pressure system off the Pacific coast produced
scattered rain showers over northern California and the Pacific
Northwest. Rainfall amounts were less than half an inch. Skies were
variably cloudy over the Great Basin and Northern Rockies. Sunny skies
were reported over the central and southern Rockies and Desert
Southwest.
11th-17th...Across the East on Monday, a weak frontal boundary produced
light rain showers over the eastern Great Lakes, the upper Ohio
Valley, and the interior Northeast. Rainfall amounts were generally
minimal, if there was enough to measure. Widespread light to moderate
rainfall totals were reported in Michigan today, where over a quarter
of an inch of rain was reported over parts of the state. Beaver
Island, Michigan, reported the most rain, at 0.40 inches. Partly
cloudy skies and mild seasonable temperatures were reported across the
rest of the Ohio Valley, the Tennessee Valley, the Mid-Atlantic
states, and the Carolinas today. Warm temperatures were reported over
parts of the Southeast today, where highs in the 70s and lower 80s
were reported. Over the central states, a potent upper-level
disturbance continued to progress slowly eastward over western Texas,
bringing scattered rain showers and thunderstorms to the area as well
as the southern Plains. Though no severe weather was reported during
the day today, heavy rainfall amounts of more than 2 to 3 inches
produced pockets of flash-flooding across Texas. Lubbock, Texas, was
hit hard by heavy rainfall today, recording 1.90 inches of rain. The
heavy rains caused flash-flooding across the city, closing roads and
swamping many vehicles. Brownsville, Texas, was hit the hardest of
anywhere in the state today, reporting 4 and three-quarters inches of
rain, with significant flash-flooding during the afternoon. Roads were
covered by as much as three to four feet of water, causing numerous
traffic problems in the city. Generally dry conditions were otherwise
observed across the remainder of the Plains states and the Mississippi
Valley today. In the West, scattered rain showers and thunderstorms
were reported over New Mexico today. Rainfall amounts were generally
on the moderate side- Clovis, New Mexico reported the most rain at
0.91 inches. Elsewhere, a frontal boundary pushed into the interior
Northwest, the northern Rockies, and the northern High Plains,
bringing isolated rain showers to this area. Dry conditions dominated
elsewhere over the Intermountain West, the Desert Southwest, and
California. In southern California, hot temperatures, strong easterly
winds, and very low humidities kept the fire danger at very high
levels.
The country's main active weather occurred along the Gulf Coast as a
low pressure system moved eastward through the region. Due to its
proximity to the Gulf of Mexico, it pulled a tremendous amount of gulf
moisture into the Southeast. Thus, very heavy rain and extremely
strong thunderstorms formed in eastern Texas and Louisiana. One
tornado even formed in southern Louisiana and caused some minor damage
to a few buildings and houses. There were also several reports of hail
damage in southeastern Texas. The Southeast rose into the 70s and 80s.
Warm moist flow was observed through the eastern third of the country
and provided more areas of precipitation. Scattered rain showers were
noted through the Ohio Valley, while more organized rain moved through
the Northeast. The warm flow through the Northeast created another
warm day with temperatures in the 50s and 60s through most of New
England. This warm weather caused rivers and streams in the area to
melt and create dangerous damming ice flows that had the potential of
causing flooding throughout New England. Light rain was noted from the
Dakotas through Michigan, while temperatures in the region ranged from
the 30s to the 40s. The Southwest once again rose into the 70s and
80s, while California saw temperatures in the 60s, 70s, and 80s.
In the eastern part of the nation on Thurday, a cold front produced
wide-spread showers and thunderstorms across the Southeast, the
Tennessee and southern Ohio Valleys, and the Mid-Atlantic. This same
cold front also produced heavy snow showers across portions of the
Northeast, including northern Pennsylvania, New York, Vermont, New
Hampshire, and Maine. Rainfall totals along the storm's path ranged
from a tenth of an inch to nearly two inches across portions of
Louisiana, Florida, Alabama, Ohio, Pennsylvania, and West Virginia.
Skies cleared across much of the Mississippi Valley by the afternoon,
with only a few scattered showers reported across the south. In the
western two-thirds of the nation, a weak upper-level disturbance
brought scattered showers to portions of Kansas, Missouri, and
northern Oklahoma, while the remainder of the central and southern
Plains saw partly cloudy skies and dry conditions. Further north,
moderate snow showers fell across portions of the northern Plains,
including western Wisconsin, northern Minnesota, and eastern North
Dakota throughout the afternoon and early evening hours. Scattered
showers also fell across portions of southern Iowa and northern
Illinois as an upper-level disturbance progressed eastward. Further
west, high pressure provided partly cloudy to clear skies and dry
conditions across the Southwest, along the Rocky Mountains, the Great
Basin, and California. A Pacific storm system produced high elevation
snow showers and valley rain across Washington this evening, with
partly cloudy skies and dry conditions reported across most of Oregon.
The eastern third of the nation, a storm system produced scattered
showers and thunderstorm across Florida, the eastern Tennessee Valley,
and the Middle Atlantic states. This activity produced occasional
lightning strikes, wind gust up to 40 mph, and localized heavy
rainfall amounts. Farther north, a cold front produced scattered snow
showers across the eastern Ohio Valley and the Northeast. Snowfall
amounts of one to two inches were reported across the area, with
localized higher totals in eastern New York and Connecticut.
Meanwhile, skies were mostly cloudy with dry conditions across the
rest of the region. Overnight low temperatures were in the teens and
20's across the Great Lakes, the Northeast and the Ohio Valley. Across
the Tennessee Valley, the Middle Atlantic states and the Southeast low
temperatures were in the 30's and 40's. Across Florida low
temperatures were in the 60's. In the western two-thirds of the
nation, a weak upper-level disturbance moved out of the region with
showers ending across portions of northern Texas and the lower
Mississippi Valley. Across the rest of the central and northern
Plains, skies were partly cloudy with dry conditions. Farther north,
moderate snow showers came to an end across portions of the upper
Mississippi Valley, including western Wisconsin, northern Minnesota
and eastern North Dakota throughout the early morning hours. Farther
west, high pressure provided partly cloudy to clear skies and dry
conditions across the Southwest, along the Rocky Mountains, the Great
Basin and California. A Pacific storm system produced high-elevation
snow showers and valley rain across Washington this evening, with
partly cloudy skies and dry conditions reported across most of Oregon.
Overnight low temperatures were in the teens and 20's across the
northern Plains and the upper Mississippi Valley. Across the central
Plains low temperatures were in the 20's and 30's, while across the
rest of the region low temperatures were in the 40's and 50's.
18th-24th...In the eastern part of the nation, snow showers have tapered
off across the Northeast, with only light snow showers being reported
early this evening across Maine, New Hampshire, and isolated areas of
central and western New York. Snowfall amounts have generally ranged
from a trace to a half inch from late this afternoon into the evening
hours. Otherwise, high pressure has allowed for partly cloudy to clear
skies east of the Mississippi River with temperatures across the
region near to below seasonal normals. High temperatures across the
east have ranged from the low 20's to mid 40's across the Northeast,
Great Lakes, and northern Mid-Atlantic; the 40's and 50's across the
remainder of the Mid-Atlantic, the Ohio and Tennessee Valleys, and the
upper Mississippi Valley; and the 50's to mid 70's across the
Southeast, central and southern Mississippi Valley, and Florida.
Across the western two-thirds of the nation, an upper-level
disturbance generated light to moderate snow showers across northern
Minnesota and far northeastern North Dakota this afternoon and into
the evening. The same system also produced scattered rain showers
across central and southern Minnesota, northern and eastern North
Dakota, and western Wisconsin. Further south, a weak area of low
pressure produced partly to mostly cloudy skies and light rain showers
across western Texas. Meanwhile, a broad area of high pressure
centered over the central Rocky Mountains, produced clear to partly
cloudy skies across the central Plains, the Rocky Mountains, the
Southwest, the Great Basin, and California. An approaching Pacific
storm system brought partly to mostly cloudy skies to coastal
Washington and Oregon, while the remainder of the region saw partly
cloudy skies and dry conditions throughout the afternoon and evening
hours. Temperatures across the west ranged from the 50's and 60's
across the far northern Plains;the upper 50's to low 80's across the
central and southern Plains; the 70's to low 90's across the Desert
Southwest and central Great Basin; the 50's to low 90's across
California; and the 40's to 60's across the Pacific Northwest,
northern Great Basin, and northern Rockies.
The East experienced, lingering snow showers continued to impact
portions of New England through the early afternoon hours. Light snow
accumulations of 1 to 3 inches were observed. Rain showers impacted
portions of the Tennessee Valley as well, but no significant rainfall
was observed. The remainder of the East was under the influence of
high pressure, bringing partly cloudy skies with dry conditions.
Across the central third of the nation, light to moderate rainfall
impacted portions of the southern and central Plains and the upper and
middle Mississippi Valley. Periods of heavy rainfall were observed
with this activity. Other rainfall totals ranging from a tenth of an
inch to a quarter of an inch were observed across the remainder of the
affected region. The northern Plains and lower Mississippi Valley
remained dry with fair skies and nice conditions with high pressure
fixed over these regions. In the West, a strong upper level trough
continued to bring rain with embedded thunderstorms to portions of
California, the Great Basin, and the central Rockies. San Carlos,
California received the highest rainfall total for the region at 0-
point-28 inches, with other locations receiving up to 0-point-2 inches
of rainfall. Skies remained variably cloudy across the Desert
Southwest and the Pacific Northwest as high pressure remained fixed
over these regions.
In the East, showers and thunderstorms impacted most of the Ohio
Valley, the Middle Atlantic, and portions of the southern Great Lakes
region. A few of these storms produced periods of heavy rainfall with
Muncie, IN 1.82, Columbus, OH 1.82, Dayton, OH 1.67, Peoria, IL 1.32,
Newark, OH 1.26, Eagle Creek, IN 1.22.
High pressure remained in control over the eastern United States,
bringing partly cloudy skies with dry and fair conditions. Across the
central United States, scattered afternoon and evening thunderstorms
impacted portions of the southern and central Plains, as well as the
middle Mississippi Valley. Davenport, Iowa received 1.10 inches of
rainfall from this activity, while Springfield, Missouri reported 0.92
inches of rainfall. Isolated strong to severe storms impacted portions
of western Texas as well, with nickel sized hail reported near
Channing, Texas and Cactus, Texas. High pressure was in control across
the remainder of the central United States, bringing fair skies with
dry conditions. In the West, thunderstorm activity over western Texas
spread westward to impact portions of the southern Rockies. Hail of up
to 2 inches in diameter was observed near Queen, New Mexico, with hail
of an inch in diameter observed for Hope, New Mexico and Whites City,
New Mexico. Scattered rain showers impacted the central Rockies and
the Desert Southwest in association with this activity as well, but no
severe weather was observed. Across the Pacific Northwest, scattered
rain showers built into the region from the west as a storm system
pushes on shore from the Pacific. California and the Great Basin
remained under fair skies with dry conditions as high pressure was
fixed over the region.
25th-31st...An area of rain, showers and thunderstorms pounded through
Southern Plains on Monday and caused areas of significant flooding.
Many places even set record daily maximum rainfall and numerous
highways and roads were closed over central and southern Texas. Apart
from the excessive rainfall, a touch-down tornado was observed at
Hondo, Texas in the afternoon. Out West, a Pacific storm system kept
the Pacific Northwest and Northern California cloudy and cool for most
of the day. Rain showers were on and off all day. On the other hand,
Southern California remained dry and warm, except the coastal region
where coastal low clouds persisted. In the Great Lakes and Northeast,
a line of moderate to heavy rain pushed through western Great Lakes
early Tuesday and produced areas of hail and high winds. Near 1 inch
hail in diameter fell in Eckerman, Michigan. This was due to a front
pushing through the region early in the day. Farther east, rain and
scattered thunderstorms developed over the Northeast as well. New York
received the most rainfall with a few places reported severe
thunderstorms and flooding. Dry and warm weather continued across the
Southeast as high pressure remained firmly in place. It was a warm day
across much of the nation on Monday. The exception was the Pacific
Northwest, Northern California and New England where afternoon
temperatures were only in the 40s and 50s. Otherwise, the majority of
the nation was in the 70s and 80s.
In the East on Wednesday, a stationary front located over the Great
Lakes produced scattered showers and thunderstorms throughout the
afternoon. Severe thunderstorms produced hail in Pennsylvania and
Michigan. Rainfall amounts were generally less than half an inch.
Further to the south, scattered showers and thunderstorms also
developed in the Deep South during the afternoon hours. No severe
weather was reported. High pressure produced partly cloudy to mostly
sunny skies and dry conditions over the Southeast, Ohio Valley, and
Northeast.
Across the central region, showers and thunderstorms developed from
the Gulf Coast to the Midwest ahead of a low pressure system. Severe
thunderstorms developed in Arkansas, Louisiana, and eastern Texas, and
hail up to the size of golf balls fell in Plain Dealing, Louisiana.
Gusty winds also downed trees in the area. Rainfall amounts over half
an inch occurred in the central Plains. Skies were partly cloudy to
mostly sunny with dry conditions in the northern Plains and Upper
Midwest. In the West, a low pressure system located in the Great Basin
brought showers and thunderstorms, along with snow showers to the
area. Snowfall accumulations over six inches were recorded at higher
elevations. Rainfall amounts over half an inch fell in Idaho. Gusty
winds in excess of 60 miles-per-hour were measured in Montana and
Nevada. Skies were partly cloudy with dry conditions over the Desert
Southwest and southern Rockies. Skies were cloudy with rain showers in
the Pacific Northwest and California.
In the East on Friday, high pressure controlled much of the region.
Skies were partly cloudy to mostly sunny with dry conditions over the
Southeast, Deep South, Appalachians, Mid-Atlantic, and Ohio Valley.
Clouds moved through the Northeast and Great Lakes throughout the day,
and a few light rain showers developed. Isolated afternoon showers and
thunderstorms developed along the eastern Florida coastline, but
rainfall amounts were light. Across the central region, showers and
thunderstorms developed over much of the area. Severe thunderstorms
brought heavy rainfall, baseball size hail, tornadoes, and gusty winds
to the southern Plains. Rainfall in excess of 6 inches were observed
in southern Oklahoma, and numerous locations over the region reported
flash flooding. More scattered storms and rain showers developed over
the Midwest and northern Plains. Snow showers were reported over North
Dakota, along with areas of freezing rain. Snowfall accumulations over
6 inches fell since midnight. Skies were partly cloudy with dry
conditions over the central Plains, before clouds moved into the area.
In the West, heavy rain showers and mountain snowfall developed behind
a low pressure system in New Mexico. Snowfall amounts were fairly
light. Another area of snow developed in the northern Rockies
throughout the day. Skies were otherwise partly cloudy with dry
conditions over the Pacific Northwest, California, Desert Southwest,
and Great Basin.
