A frontal boundary in the vicinity Sunday morning should allow for precipitation to start around daybreak across the region. Initially, this precipitation likely will start off as either snow or freezing rain.
Ground temperatures will warm slowly through the morning hours, but before they rise above freezing, a light dusting of snow or very light glaze of ice, could make for slick roads, especially on bridges and overpasses.
Conditions should improve by lunch time, as temperatures slowly rise above freezing. Make plans now to allow some extra time to travel Sunday morning.
The National Weather Service in Louisville has issued a Flood Watch for southern Indiana and central Kentucky, including Lexington from Sunday evening through Tuesday afternoon.
A slow-moving frontal boundary will linger over the region Sunday into Tuesday. Lift along this boundary will cause a prolonged period of light to moderate rainfall, causing rises on area rivers and streams and likely periods of street flooding.
This rainfall could cause some area rivers to rise to moderate flood stage. Also, flash flooding will be possible Monday night as a trailing cold front crosses the region.
A Flood Watch means there is a potential for flooding based on current forecasts.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
