Technical Forecast Discussion
Short term (Wednesday 8/28 through Saturday 9/1)
Troughing will take over at the upper level late tonight as a cold front is pushed into the state late tonight /early Thursday. The front should begin to influence weather patterns around midnight . Fair conditions and low cloud cover will remain for the early evening as it continues to be humid with lows in the high 60s. The frontal boundary is expected to arrive early Thursday. CAPE will be low during this time as nighttime cooling will be in effect, so storms will be scattered and short lived to begin with. Upper level troughing will over the region for day on Thursday. The frontal boundary will become quasi-stationary around Thursday afternoon, slowing it’s progress over Athens, so storms and showers will continue to be a possibility through the late morning and up until around midnight. Nothing stands out in terms of severe potential. Localized flooding could possibly be an issue if areas experience long periods of storms. Shearing is absent, but models have CAPE maxing around 2000 and being present for most of Thursday, so precipitation could be long lived. CAA will be very noticeable Thursday night as dry, cool air follows behind the front bringing lows in the low 60s. Upper level ridging will return on Friday as dry air pushes out any remaining convection. This will in return create clear and calm conditions. Some CAA will still be present as temperatures slightly decrease into the mid 80s on Friday. The day on Saturday will be a continuation of these conditions, but clouds will return Saturday night as another trough will push a warm front near the region that night.
Long term (Sunday 9/2 through Tuesday 9/4)
The region will still be in an area of ridging Sunday, although it will much broader and weaker. Moisture will still in the region on Sunday, enough to create humid conditions. CAPE will be present during max heating time, so a chance for showers and isolated storms will exist as moisture and instability could interact that that time. Labor day looks to be clear, yet slightly humid. Upper level ridging will trap moisture from the previous warm front in the region as high pressure moves over West Virginia. The high pressure will stop any convection interacting with available moisture. High pressure will remain stationary as the upper level ridge strengthens mid-Tuesday. This will bring more warm air from the South leading to a hotter day with possible highs in the low 90s.
The next technical discussion will be Sunday 9/2
