...Rain sticking around through tonight, dry tomorrow...

Widespread showers with some embedded storms continue to progress across the eastern half of the state early this evening. Coverage becomes more scattered to the west and eventually pushes east of the state late tonight and into early tomorrow morning. Much of the state has already seen 1 to 3+ inches of rainfall. The highest totals have been located across SW KY where Flash Flood Warnings and Flood Advisories are in effect. If you encounter a flooded road, turn around and find an alternative route.

After a dry Tuesday, precipitation returns on Wednesday. This event will feature a mix of precipitation with snow across Northern KY and rain to the south. Saying that, this looks to be a light accumulation event. We do dry out the rest of the work week, but looking ahead, outlooks hint at the wet pattern continuing into the first week of February.

New Jersey, and refreshment taverns were set up in the middle of the river
to warm pedestrians. (David Ludlum)
At 7 PM a display of the Northern Lights danced above Burlington VT. Its
light was equal to the full moon. Snow and other objects reflecting the
light were deeply tinged with a blood red hue. Blue, yellow and white
streamers were also noted. (The Weather Channel)
Alta UT was in the midst of a storm that left the town buried under 105
inches of snow establishing a record for the state. (David Ludlum)
The temperature fell below 32 degrees at Lexington, and would not rise back 
above freezing until February 13, which is the longest Lexington has ever 
stayed at or below freezing (18 full calendar days). (NWS Louisville)
