Rain on the way – near record temps Tuesday




Monday into Tuesday set-up

  • Heavy snow north and west of low pressure center track;
  • Severe storms/heavy rain south and east of low pressure center track.
  • Low pressure moves NE out of Texas Panhandle and deepens as it moves through Iowa Tuesday into Lake Huron Wednesday – strong southerly winds will pull warm moisture-laden air up the Mississippi River Valley into portions of the Midwest, Lower Ohio River Valley.
  • Severe storms to develop Monday-Monday night over portions of TX, LA, AK, OK, TN, MS – shifting east later Tuesday into Wednesday.
  • Band of heavy snow will lay out from Colorado/Wyoming (1 to 3-feet in higher elevations) and anywhere from 6 to 12-inches from Nebraska and South Dakota into Minnesota – Ice storm likely NW Iowa into southern Minnesota
  • Heavy rains overlay the severe storm outlook area into Kentucky and the lower Ohio River Valley – the light green-shaded area depicts a general area of widely scattered t-storms and .5 to 1.5-inch rainfall.
  • Chicago can expect a few t-storms with moderate to locally heavy rains – rainfall totals 0.5-inch north to 1.5-inch south Monday night.

Warmth and rain on tap for Chicago

As low pressure strengthens in the Central Plains and its associated warm front moves north out of Central Illinois, there will be extensive low cloudiness and scattered dense fog early Monday morning.  As the front moves into our area toward evening, moderate to locally heavy rains will spread from the south to the north.  Overnight rains could give upwards of an inch at many locations. 

The warm front will surge north of our area toward Monday evening, and temps will be on the rise overnight.  Strong SW winds will boost readings to near record highs in the lower 60s on Tuesday.  As the low pressure tracks across Michigan, the associated cold front will swing through our area from the west later Tuesday, temps falling overnight. Cold temps/snow showers likely Wednesday/Thursday.


  • Strong 120 mph SW jet aloft to our west moving slowly east
  • Strong SW low-level jet shifting just to east of our area
  • Cool air spreading over Rockies/northern Plains
  • Cold front will move through Chicago later Tuesday, preceded by record-warm air and followed by colder air/snow showers later Wednesday/Thursday
