temperature

[JERRY]

Hello to the group! Just joined and already have one question{for now} about  the weather Sunday. I observe the temp has risen almost 5 degrees since before dark. The  tv weather folks predict mid 20's tonight. Q: Why the rise in temp as we move into the late afternoon and early evening? I monitor the weather station in Jonesboro.

Hey Jerry,

I am an employee for the GAEMN and a broadcast meteorologist. There is
a good reason for the rise in temperature. The storm that produced the
snow was a cold upper level area of low pressure. As the heavy snow
fell across the area, cold air was pulled down from aloft and that is
why the temps fell. As the low pressure pulled away this evening and
the precip ended, the source of cold air was lost and temperatures
responded by rising a few degrees. I hope this answers your question.

Eddie, The answer anawered my question nicely. Can I conclude an upper
level high as it passes would dump cool air?

Jerry,

Generally speaking, when an upper level high or ridge is over our
area, that leads to sinking or compressed air and warmer temps.
Especially in the summer, when we have an upper level ridge directly
over our area, we see our hottest temps. When a surface high pressure
moves in, it normally brings cooler/colder air while you are on the
east side of the center, but then you see warmer air as you get on the
west or back side. This, of course, is most common in the cooler
months.
