DISCUSSION
ISSUED AT 122 PM CST SUN JAN 25 2026
TODAY-MONDAY: BITTER COLD RETURNS TONIGHT INTO MONDAY MORNING
A SHORTWAVE TROUGH MOVES DOWN INTO THE UPPER MIDWEST THIS EVENING
BRINGING ANOTHER SHOT AT BITTERLY COLD AIR. AT THE SAME TIME, THE
SURFACE PRESSURE GRADIENT TIGHTENS UP A LITTLE, INCREASING WINDS
THROUGH THE OVERNIGHT. SUSTAINED NORTHWEST WINDS WILL MOSTLY RANGE
FROM 5 TO 10 MPH, WITH SOME LOCATIONS WEST OF THE MISSISSIPPI . LOW
TEMPERATURES TONIGHT GET BACK DOWN INTO THE TEENS BELOW ZERO WITH
LOCATIONS NORTH OF I-94 SEEING LOWS INTO THE LOW 20S BELOW ZERO.
COMBINING THESE TEMPERATURES WITH THE WINDS, APPARENT TEMPERATURES
TONIGHT WILL DROP INTO THE 25 TO 35 BELOW ZERO RANGE. IMPROVEMENTS
IN THE WIND CHILL BEGIN BY MID MONDAY MORNING AS WINDS SHIFT TO THE
SOUTHWEST AND GOOD WARM AIR ADVECTION PUSHES INTO THE REGION. THIS
TEMPERATURE ADVECTION WILL HELP TO PUSH TEMPERATURES INTO THE LOW TO
MID TEENS FOR MOST LOCATIONS.
REST OF MONDAY-SUNDAY: COLD CONTINUES THROUGH THE WEEK, PERIODIC LOW
SNOW CHANCES
NORTHWEST FLOW ALOFT CONTINUES FROM MONDAY THROUGH MUCH OF THE WEEK.
BEING IN THIS FLOW PATTERN ALLOWS THE COLD AIR TO REMAIN OVER THE
REGION, RESULTING IN HIGH TEMPERATURES IN THE SINGLE DIGITS TO MID
TEENS AND LOW TEMPERATURES IN THE SINGLE DIGITS ABOVE AND BELOW
ZERO. HEADING INTO THE WEEKEND, SOME WEST TO SOUTHWEST FLOW RETURNS
WHICH HELPS TO RAISE HIGHS INTO THE UPPER TEENS ON SATURDAY AND LOW
TO MID 20S ON SUNDAY. A FEW SHORTWAVES MOVE DOWN INTO THE UPPER
MIDWEST THROUGHOUT THE WEEK GIVING SOME SNOW CHANCES TO THE AREA.
THE FIRST WAVE MOVES DOWN MONDAY NIGHT AND INCREASES SNOW CHANCES
NORTH OF I-94 WHERE UP TO 0.5" WILL BE POSSIBLE. SOME FLURRIES MAY
REACH AS FAR SOUTH AS I-90. A COUPLE OTHER WAVES PASS THROUGH LATER
THIS WEEK BUT STILL SOME DIFFERENCES REMAIN IN TIMING AND LOCATION
RESULTING IN POPS UNDER 10%. SATURDAY NIGHT INTO SUNDAY LOOKS TO
HAVE THE BEST WIDESPREAD CHANCE FOR LIGHT SNOW TO RETURN TO THE
WHOLE CWA AS THE GFS, ECMWF, AND CMC ALL SHOW A CLIPPER COMING DOWN
INTO THE UPPER MIDWEST.
