Here's what I'm looking to build.......hopefully someone has some good
advice or maybe even has already built something similar.

I've build circuits to detect temperatures in the past but I'd like to
take it to the next level. I want to build a small, inexpensive
circuit that will detect ambient air temperature changes, display temps
to a small digital display, and even better, somehow log temp data (per
second or so). My initial thoughts are to use a usb flash drive since
they are small, inexpensive, and easily used with a desktop PC for
later analysis of the temp data. Basically I want to place the
thermometer at a location, leave, have the temp data logged, and be
able to later review the temp data on a computer.

You'll need a fairly powerful (micro)computer to talk directly to a
USB peripheral. You might do better with a CF or SD card.

Or include some flash in the thermometer and make _it_ a USB peripheral.
USB masters are hard to make, but slaves are fairly easy if you don't
try to cross every 't' and dot every 'i' in the plug & pray mechanism.

Or if you just pretend to be a serial/parallel port, and use one of the
canned chips, which present an 8 bit 'friendly' bus.
