Technical Forecast Discussion
Short term (Wednesday 2/6 through Saturday 2/9)
After a brief period of clear conditions, a upper level trough pushes a low pressure system into the Midwest. Models show the system to be in its frontal wave stage as the warm front moves northward and is likely to produce rain showers for the region. Despite high moisture values, precipitation looks to be light as the strongest upper and mid level flow will be west of the region. Heavier precipitation looks likely for Thursday as the GFS and EURO have pockets of precipitable water around 1.5-1.7 near Athens. Dry air stop chances for precipitation on Friday, but clouds will remain as the moisture moves upstream of the through the region. High pressure on Saturday will finally push out clouds as zonal flow moves over the region.
Long term (Sunday 2/10 through Tuesday 2/12)
Zonal flow will continue to disrupt the flow of moisture for the day on Sunday, but a developing low pressure system that moves from the Central Plains to just south of the area will allow for moisture to move back in. As a cooling trend looks likely on Sunday, precipitation could be a mix of rain and snow for that evening. A trough building out on the Pacific coast will allow for ridging to form over the Midwest. GFS shows a decrease in moisture on Monday as a result in the ridge, but a nearby low pressure system near Indiana could still bring clouds and precipitation for Monday. On Tuesday, this aforementioned system will enter the region. The system will be in its occluded stage by then and occluded frontal boundary looks to pass over Athens. WAA will occur afterwards as southerly flow moves in after the front.
