Technical Forecast Discussion

Short Term (Thursday 9-22-22 through Sunday 9-25-22)

Broad high pressure has begun to settle into the area, providing pleasant and much cooler conditions just in time for the first day of fall! A tight pressure gradient can be seen on the 500mb relative vorticity map, which has also provided breezy conditions today and will continue through this evening due to the upper trough and closed low pushing east. For now and most of the weekend, we will have dry conditions persist as upper level ridging and the broad surface high continue to dominate. However, by Saturday night, an upper trough looks likely to push eastward into our area, sending a cold front through and therefore creating chances for showers and thunderstorms mainly on Sunday. The main activity should occur along the frontal boundary, and the timing will mostly depend on how quickly it moves through.

Long Term (Monday 9-26-22 through Thursday 9-29-22)

Looking ahead, precipitation chances should dissipate by Monday morning, but some light showers are possible to linger as troughing continues over the region, finally pushing east on Thursday. Much of the week should remain dry as surface high pressure builds in, filtering in drier air despite troughing persisting. Temperatures will be fall-like throughout this period as to be expected compared to the 90 degree weather Athens experienced yesterday.
