WINTER STORM WARNING ALL AREAS 4 AM TOMORROW TO 6 PM SATURDAY
I'm keeping this short - as I'm preparing to head to Dayton, Ohio tomorrow.
Forecast is still on track as previously talked about. Low pressure currently near New Orleans will move up the east coast. At the same time we will see an inverted trough move through and a secondary low develops in the Tennessee Valley. Moisture will be thrown into this storm from both the Gulf of Mexico and the Atlantic at the same time. An upper level low will track directly over us, which will enhance things on Friday night especially.
Basically, the technical setup favors the following timeline:
2-6 AM: Precipitation moves in from south to north. It will be a mix of snow, sleet and maybe freezing rain - more in the way of snow to the north.
6 AM-6 PM: This will get tricky depending on where you are. If you're in the northern counties of the Cincinnati area and up to Dayton, you will continue to see more snow than anything else but still a mix of snow with first freezing rain and sleet, then rain. South of that, expect rain to mix in more and more the further south you go. If you're in the far southern counties, you could even go over to plain rain for a time.
6 PM Friday to 6 PM Saturday: Expect the changeover to all snow to occur in areas where it hasn't already. If you're north of Dayton you may be all snow through the entire event.
Total Accumulations:
Metro Area (or along and ~25 miles north and south of a Versailles to Hillsboro line): 4-7"
North suburbs to I-70: 5-9"
South of line from Vevay, Indiana to Augusta, Kentucky to Maysville, Kentucky: 2-5"
I will be in Dayton Friday afternoon as I mentioned at the top of this post and will tweet from the NKYWx Twitter account all day with LIVE updates from there.
