Key Points – Monday, November 21, 2016 – short term

Synopsis: It’s a chilly but beautiful day across the Midwest today, with barely a cloud in the sky as high pressure dominates. Cloud cover increases from west to east this evening into the overnight as our next storm system moves through the Zones (details in the video). We could have a little bit of frozen precipitation mixing tomorrow/Wednesday mornings as this system progresses east entering into an area where temps will be in the 30s, but we are not expecting any travel issues as temperatures will quickly rebound into the 40s. Thanksgiving across the Zones should be fairly¬†uneventful this year as a brief period of high pressure sets in before our next system late week moves in.

Today: High pressure in control today keeping the skies basically cloud-free, but chilly as temps are only in the low to mid 40s across the Zones.


Highs today won’t get much warmer than where we are right now, ranging mainly from the low to mid 40s…some locations in southern IL may briefly touch in the low 50s before we turn colder into the overnight.


Our system moves in Tuesday into Wednesday across the Zones, could have some frozen precip mixing in initially tomorrow and Wednesday mornings as temps will be in the 30s, otherwise an all-rain event as temps warm into the 40s tomorrow and Wednesday…not expecting travel hazards with this system at this time as temperatures will be too warm for any precipitation to have time enough to freeze on to surfaces.


Total rainfall across the area…forecasting 0.5″ generally with isolated higher amounts possible across portions of central/southern IN/IL.


This system will exit the Zones Wednesday night into Thursday morning east, ushering in a brief period of high pressure just in time for Thanksgiving…forecast right now is partly sunny skies and temperatures in the 40s to low 50s.


Confidence and Risk:

  • High confidence skies will remain mostly sunny today as high pressure dominates our weather
  • Above average confidence in the timing of our system as it moves west to east tomorrow into Wednesday
  • Average confidence that there may be a little frozen precipitation mixing in Tues/Wed mornings across the northern locations of our Zones, roadways should stay unaffected as temperatures will be too warm for the precipitation to freeze on surfaces.
  • Above average confidence Thanksgiving will be rain-free and partly sunny this year, with highs in the 40s and lower 50s.
