Cold Week AheadBy
What a difference 24 hours makes. From the balmy mid-50s of Saturday, to a return of the winter chill today. Temperatures at this hour are good 20-25 degrees colder than this time Saturday.A few light radar returns continue with a slow moving line of rain/snow showers in southern Indiana. This area of precipitation is heading southeast and clouds are starting to clear due to the departure an upper level disturbance.
Without a blanket of cloud insulation tonight, expect lows to drop into the lower teens Monday morning… though we’re expecting a bright start tomorrow.
Clouds increase Monday afternoon in advance of our latest upper level disturbance… a feature that brings a new wave of light snow to Central Indiana Monday night and pre-dawn Tuesday. Tough to pinpoint the exact location, but underneath this wave of light snow another inch will be possible.
After a cloudy start Tuesday finishes brighter, but the focus will be on unseasonably cold lows Wednesday morning.
Many locations will likely drop below zero for another time this winter Wednesday morning. The frigid start will be followed by “highs” in the upper teens… which is colder than the average “low” for this time of year which is 27.
We’re eyeing next Sunday for a potential accumulating snow. Both the Euro and GFS models (pictured side-by-side below) show a wave of moisture moving across the I-70 corridor. Not pictured, but offering more support of a snow next weekend are ensemble data. It’s a long way out, but something we’ll be keeping tabs on and providing updates in the week ahead.
Have a great evening and thanks for reading the blog – Sean Ash
