Friday, December 16, 2011: The North-South Split
Good Friday morning, everybody. We have a very split forecast today, between the SOGGY SOUTH and the DRY but chilly NORTH. Most of the southern Kentucky precipitation is falling as rain, although that isn't the entire story. There have been reports of sleet already this morning in southern Breathitt County and also near Booneville in Owsley County. Meanwhile, lots of virga is indicated on radar along and north of I-64, with very little - if any of this actually reaching the ground at midmorning.

This will continue through much of the day, with little more than occasional sprinkles, flurries and light sleet pellets falling near I-64. Dry weather will likely continue across northern Kentucky, and a couple of tenths of an inch of rain will end as a lighter sleet / snow / rain mix in southern Kentucky late today.
Here is the latest WRF forecast for precipitation today. You'll notice that razor-sharp cut-off.

Most of the weekend will be partly to mostly sunny and seasonable, with highs in the 40s and lows in the 20s. HOWEVER, a weak clipper-like system will dive southeast from the Great Lakes into the upper Ohio Valley. Most of the computer model guidance this morning keeps the precipitation farther north and east, closer to Wheeling, WV and Pittsburgh, PA. However, the latest Canadian model continues to suggest that a few snow flurries may clip our northern and northeasternmost counties. Here is the latest Canadian forecast for precipitation between 7 AM and 1 PM on Saturday.
In and around the metro area, though, all of Saturday and Sunday should be dry.
Have a great start to your weekend. Christmas is almost here! It's hard to believe. Also, Winter officially begins next Wednesday night / Thursday morning, just after midnight.
I plan to post an update on Saturday.
