Buckle Up For A Busy Winter Pattern…Thursday featured the coldest December 15th high (13 degrees) in a whopping 27 years. Talk about impressive.  This was good for an amazing 26 degrees below average.  Let that sink in…

We’ll wrap up the work week and head into the busy weekend before Christmas with a new round of challenges.  A couple of warm fronts will lift north through central IN Friday.  Snow showers may accompany the first warm front early Friday before the second warm front lifts north Friday night.  This will result in more widespread wintry precipitation, likely to begin as a period of light snow before a quick transition to sleet and freezing drizzle during the overnight.  Temperatures will warm overnight Friday and precipitation will change to light rain Saturday morning.  That’s when our attention turns to the first of two cold fronts that will sweep through the state.  The first cold front will lead to a quick changeover to sleet and snow Saturday evening (thinking between 6p-8p as of now).  As a secondary wave of moisture moves northeast along the boundary, expect a light accumulation of snow Saturday night.  The second cold front (arctic) will blow through late Saturday night and early Sunday morning and lead to a frigid Sunday.  That 25 degree high you see Sunday will come at midnight as temperatures crash through the day.  Add in a stiff northwest wind and wind chill values will fall below zero (yet again) in the Sunday-Monday time frame.

We’ll briefly calm things down during the early Christmas week period and remain cold.  Our next storm system is slated for a mid week arrival and could deliver a round of accumulating snow Wednesday night into Thursday morning.  More on that after this weekend system.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 2″ – 4″
  • Rainfall: 0.20″ – 0.40″
