Technical Forecast Discussion
Short term (Wednesday 10/24 through Saturday 10/27)
Upper level ridging becomes less uniform as it moves into the Midwest. Skies stay clear as moisture stay above the Great Lakes for Wednesday as high pressure rests over Northern Michigan. On Thursday, a few shortwave disturbances are presence in the Central Plains, but the continuation of clear conditions will continue. Heading into Friday, the shortwave disturbances will bring with them a large mass of moisture. Models show showers occurring on Friday, as vorticity will exist ahead of this pre-frontal air mass that will act as a forcing mechanism. A decaying low pressure system moves in near the region on late Saturday that brings in another mass of moisture and stronger instability that will likely bring in showers Saturday night.
Long term (Sunday 10/28 through Tuesday 10/30)
The upper level trough will deepen late Sunday. This will bring in a deep-layered mass of moisture that makes showers likely for late Sunday. Models show a weak jet streak to exist over the region on Monday. Athens will be situated over the area of the jet streak associated with sinking motion resulting in a decrease in cloud cover and moisture as time progresses. Showers should subside by Monday night. Upper level ridging will enter the area late Tuesday that will start a small warming trend and clear conditions for the later half of the work week.
