STORM ALERT...

My thoughts: Around midnight tomorrow night, a large band of heavy snow comes over the region. Southern Indiana and the counties along the Ohio River will see 3-5 inches of snow with this band, with north central Kentucky seeing 2-4 inches of snow and sleet with .1" ice (freezing rain). Tuesday night-Wednesday morning will have another band of wintry precipitation. Look for 1-2 inches of additional snow/sleet over southern Indiana, with .1-.25" of ice after the snow changes over. North central Kentucky will see mostly ice with up to 1" additional snow/sleet accumulation and around .25" of ice.
Totals: Southern Indiana: 4-7" snow/sleet, .1-.25" ice...North central Kentucky: 2-5 inches snow and sleet, .2-.3" ice.

NWS: The National Weather Service in Louisville has issued a Winter Storm Watch from Monday evening until Wednesday morning for the entire southern Indiana/north central Kentucky area. 3-6 inches is likely over these areas, with up to .25" ice.

HPC says a 40% chance of at least 4 inches before 8am Tuesday, and a 10% chance of 8 inches. HPC says a 10% chance of at least 4 inches after 8am Tuesday-8am Wednesday. Also, HPC says a 10% chance of .25" of ice over southern Indiana, and 40% chance over northcentral Kentucky (8am Tuesday-8am Wednesday).

John Belski: My latest thinking is for a burst of snow Monday night in the 3 to 6 inch range. As the second surge of moisture comes in on Tuesday, the snow/mix line is the big question and I just don't have an answer. I think the GFS is pushing it too far north so am tempted to say sleet and snow north of 64 and freezing rain and rain south of 64. Really hard to pinpoint for now. Remember the storm in December. The heaviest snow was supposed to be right through Louisville and in the last 6 hours before it hit....it shifted 20-30 miles to the south. It seems like we are always on the borderline. I can see Vincennes to Seymour getting 8 inches or more....not sure if that will happen in Louisville. HPC still has a moderate icing risk here on Tuesday along with a moderate risk for heavy snow.... even if we go to freezing rain on Tuesday...storm totals still could end up in the 3-7 or 4-8 inch range. No change over to freezing rain...amounts could be higher.

I will be in a high speed internet zone for most of the day tomorrow, so I should be able to take advantage of being homeschooled and post during the morning and afternoon tomorrow. (I will be doing my school while not watching the weather!) Check tomorrow for the latest details...
