DISCUSSION
ISSUED AT 351 AM CDT SUN MAR 22 2026
CURRENT SURFACE ANALYSIS PLACES LOW SLIDING THROUGH THE
MIDWEST, WHILE HIGH SETTLES THROUGH SOUTHERN
SASKATCHEWAN/MANITOBA INTO THE NORTHERN PLAINS. QUIET WEATHER
REMAINS OVER OUR AREA AS LIGHT PRECIPITATION HAS PUSHED SOUTH OF
THE AREA WITH THE APPROACHING SURFACE HIGH.
FOR TODAY, COOLER TEMPERATURES ARE ON TAP AS SURFACE HIGH
SETTLES THROUGH CENTRAL/EASTERN NORTH DAKOTA. A SHORT WAVE
PUSHING INTO THE AREA COMBINED WITH WARMER AIR TRYING TO PUSH IN
BEHIND THE HIGH MAY RESULT IN SOME LIGHT RAIN OR SNOW SHOWERS
LATER THIS MORNING THROUGH THIS AFTERNOON.
MILDER DAY ON TAP FOR MONDAY AS WARMER AIR CONTINUES ITS PUSH
BACK IN, WITH HIGH TEMPERATURES FOR MANY AREAS RUNNING ABOUT 10
TO 15 DEGREES ABOVE AVERAGE. A COLD FRONT THEN DROPS THROUGH THE
AREA MID TO LATE DAY. THIS WILL RESULT IN A MODEST COOL-DOWN FOR
TUESDAY.
TUESDAY NIGHT INTO WEDNESDAY, WARMER AIR PUSHES BACK INTO THE
AREA WHILE A FEW WEAK WAVES PASS THROUGH BUILDING RIDGE TO THE
WEST. THIS WILL RESULT IN LOW TO MEDIUM PRECIPITATION CHANCES,
MAINLY LATE NIGHT TUESDAY. HIGH TEMPERATURES ON WEDNESDAY WILL
BE QUITE WARM, WITH HIGHS PUSHING INTO THE MID 50S TO MID 60S
OVER MOST LOCATIONS, ABOUT 15 TO 20 DEGREES ABOVE AVERAGE. COLD
FRONT THEN DROPS THROUGH LATE WEDNESDAY INTO WEDNESDAY NIGHT,
BRINGING LOW PRECIPITATION CHANCES THROUGH THE AREA. THIS ALSO
WILL RESULT IN MUCH COOLER TEMPERATURES FOR THURSDAY, WITH MOST
LOCATIONS DROPPING BELOW AVERAGE. GRADUAL WARMUP THEN EXPECTED
TO CLOSE OUT THE WEEK.
