Forecast Discussion
Low pressure currently in place over the Ohio River Valley will be trekking east today south of the state. A stationary front will allow for precipitation right along the front and tapering off in the far northern parts. The air at the get go will warm a bit as warm air is advected up from the valleys below, so precipitation will be a possible mix of sleet, freezing rain or snow this morning. As the day progresses, cold air will work down and turn precipitation to snow. Some bands of precipitation will be heavy, especially this morning, as strong uplift and ample moisture will combined. Later, things will become more showery as the low passes east. Overnight, the second wave of energy with this low will sweep through bringing additional snow, heavy at times as it passes. Thursday, things begin to settle a bit as a weaker trailing low follows on the heels of todays low. This will continue snow showers around the state as it passes. High pressure will start to work in later tomorrow. The main forecast problem is the frontal boundary, if it slides more north, more snow on the summits, further south, less snow. As of now, it looks like it will remain parked over the summit which is in agreement with models. Another issue with the frontal positioning is drier air north and moist air south. Pending on where the front moves, there is a chance that clearing may occur at times over the forecast period. With the summits wedged between a high north and a low south, winds will be fairly stagnant but as the two waves pass, wind speed will pick up at times. There is even the remote possibility of thunderstorms today with the amount of lift but since other ingredients are lacking, have kept them out of the 12 hour forecasts, but it should be noted. Wind chills remain out of range for statements with wind chills today 0-10 above falling to 0-10 below by sunset and then continuing to fall to 10-20 below overnight into tomorrow.
