Much Colder Air and Light Snow Likely Late Tonight-Tuesday Morning

Strong Cold Front to Bring Much Colder Air and Light Snow Late Tonight and Early Tuesday Morning 

The latest weather forecasts indicate that a strong cold front will push into the Ohio Valley late tonight and early Tuesday.  This cold front combined with a very strong upper level disturbance will bring a band of precipitation and strong winds to the region.

Gusty Winds and Falling Temps:

The cold front will cross the Ohio River early this evening, and quickly push south to the Kentucky/Tennessee border by just after midnight. Winds will pick up out of the north, with 25-30 mph gusts possible anytime after midnight. Temperatures will quickly fall into the upper 30s after midnight, and bottom out between 30 and 35 degrees by daybreak Tuesday. Wind chill values will be in the lower to mid 20s.

Early Morning Snow on Tuesday:

Precipitation will start off as rain, then briefly mix with sleet and snow before changing over to all snow before sunrise Tuesday morning. Light snow is expected to be in progress by Tuesday morning across southern Indiana and much of central Kentucky.  The snow may be briefly moderate at times.  However, with very warm ground temperatures and surface temperatures expected to be around freezing, any snow accumulation is expected to be light and mainly confined to grassy and elevated surfaces. Road surfaces are expected to remain generally wet with some reductions in visibility due to any heavier snow showers.  At this time, there may be some minor travel impacts on the Tuesday morning commute due to isolated slick spots developing on bridges, overpasses, and less traveled side roads during the most intense snowfall.   Any snow that does accumulate will melt quickly after the precipitation ends.

Below is a map that depicts the areas at risk for a light snow accumulation.  The highest risk of accumulations appear to be across portions of east-central Kentucky.  The snow is expected to quickly diminish by mid-morning with clearing working in during the afternoon hours. Temperatures will remain quite cold Tuesday afternoon with highs struggling to warm into the upper 30s. North winds of 10-15 mph with gusts up to 30 mph will result in wind chill values in the 20s throughout the day.
