Winter Storm Likely and Winter Storm Watch remains valid!
Thursdays weather looks dry as the storm makes way to our region. Overnight Thursday, short range models are bringing in the chance for a wintry mix of precipitation of both snow and freezing rain. Any snow and ice accumulation will be less than a half inch. This will make roads hazardous.
Our main attention will turn to Friday and Saturday as low pressure begins to move across our South. As this does, it will bring in a very potent winter storm with violatle conditions. Right now, upper temperatures across the Dayton area and anywhere primarily north of Cincinnati below 0°C. On the GFS, temperatures reach as low as -6°C. While Surface temperatures will be around 33-35 during the day Friday, snow will be the main concern north of Cincinnati. It does appear that overnight Thursday and into the early commute, we could see a wintry mix of snow and ice. The model progs this go around are bringing in this system earlier than previously forecasted. As we move through the day Friday, snow is expected become heavier and should fall at a modest snowfall rate. This should continue to provide for a major accumulation possible during the day and into Friday night. This will make roads treachorous as well. During the day and overnight Friday, 3-5 inches of snow is forecast, based on both the NAM and the GFS. As we move into Saturday, snow should gradually begin to taper off during the evening hours, but QPF indicating precipitation between .25-.50, and thus bringing in 3-5 more inches. This will bring snow accumulations of 6-10 inches generally. Across the south, for example around Cincinnati, we could see a bit less in terms of accumulations. Heavy swath of accumulation is expected to develop along of a line from Indianapolis all the way to say Athens, OH. This line may even extend upwards into Pennsylvania.
We begin to dry out on Sunday, with temps actually decreasing a bit, and we will continue to stay dry on Monday. Our attention then turning to a strong Alberta Clipper that will move into the region on Tuesday and into Wednesday, and this may bring in some more accumulating snow. I will not mention any accumulations at this time, but a few inches does appear probable on Tuesday. This will be closely monitored.
