DISCUSSION
ISSUED AT 320 PM CDT SUN MAR 22 2026
THIS AFTERNOON WILL SEE THE NORTHLAND REMAIN COOL AS HIGH
PRESSURE BUILDS IN FROM THE NORTHWEST. WHILE EARLY MORNING
FLURRIES HAVE LARGELY TAPERED OFF, THE CLOUD COVER HAS BEEN
PERSISTENTLY DRAPED OVER ALL BUT THE ARROWHEAD REGION. SKIES
WILL GRADUALLY CLEAR THROUGH THE REMAINDER OF THE DAY AND THIS
EVENING, WHICH SHOULD ALLOW FOR SOME SUNSHINE BEFORE DUSK FOR AT
LEAST PARTS OF THE AREA.
HIGH PRESSURE MOVES ACROSS THE AREA ON MONDAY, BRINGING PLENTY
OF SUNSHINE AND A RETURN TO MILDER TEMPERATURES. SOUTHERLY WINDS
WILL DEVELOP BY THE AFTERNOON, HELPING HIGHS CLIMB INTO THE MID
TO UPPER 40S. THE QUIET WEATHER WILL BE BRIEF AS A FAST- MOVING
COLD FRONT ARRIVES LATE MONDAY THROUGH EARLY TUESDAY MORNING.
THIS SYSTEM WILL BRING A MIX OF LIGHT RAIN AND SNOW, THOUGH
ACCUMULATIONS ARE EXPECTED TO BE MINIMAL.
CONFIDENCE IS INCREASING IN A MORE ORGANIZED WEATHER SYSTEM FOR
THE MIDDLE PART OF THE WEEK. A WARM FRONT WILL ADVANCE INTO THE
UPPER MIDWEST ON WEDNESDAY, FOLLOWED BY A DEEPENING LOW
PRESSURE SYSTEM ON THURSDAY. THIS SYSTEM DEVELOPS OVER THE HIGH
PLAINS OF NE/SE WY, THEN MOVES EAST ACROSS THE PLAINS AND MID
MISSISSIPPI RIVER VALLEY THROUGH THURSDAY. A WINTRY MIX OF RAIN,
SNOW, AND FREEZING RAIN IS LIKELY ACROSS MUCH OF THE REGION.
THE HIGHEST POTENTIAL FOR ACCUMULATING SNOW IS CURRENTLY FOCUSED
ON THE TIP OF THE ARROWHEAD, WHERE CHANCES FOR 2 OR MORE INCHES
ARE IN THAT 40 TO 60 PERCENT RANGE.
DRIER BUT MUCH COLDER AIR ARRIVES FOR FRIDAY AND SATURDAY. A
LARGE HIGH PRESSURE RIDGE BUILDS INTO THE AREA, BRINGING A POOL
OF COLD AIR FROM THE NORTHWEST TERRITORIES INTO THE AREA. FOR
NOW WE HAVE STAYED CLOSE TO THE NBM FORECAST, BUT SHOULD WE
MANAGE TO CLEAR OUT UNDERNEATH THAT RIDGE FOR FRIDAY OR SATURDAY
MORNING, OVERNIGHT LOWS BELOW ZERO ARE POSSIBLE. GIVEN THE
UNCERTAINTY AT THIS POINT IN TIME THAT PROBABILITY IS ONLY 30
PERCENT.

A PERIOD OF GUSTY SOUTHWEST WINDS UP TO 20 KTS MONDAY NIGHT, BUT
THESE DECREASE AGAIN AND TURN NORTHERLY FOR TUESDAY. CONDITIONS
