KEY MESSAGES
- ABOVE AVERAGE TEMPERATURES ARE FORECAST THIS WEEKEND,
INCLUDING TEMPERATURES INTO THE 60S AND 70S. THIS WILL GREATLY
ERODE EXISTING SNOWPACK. THIS ALONG WITH UPCOMING
PRECIPITATION BRINGS MEDIUM CHANCE FOR MINOR RIVERINE
FLOODING.
- A MORE UNSETTLED WEATHER PATTERN DEVELOPS THIS WEEKEND INTO
NEXT WEEK, BRINGING CHANCES FOR RAIN AND THUNDERSTORMS. AT
THIS TIME, THE CHANCE FOR SEVERE WEATHER IS VERY LOW.
DISCUSSION
ISSUED AT 219 PM CDT FRI APR 10 2026
..SYNOPSIS
TODAY'S SURFACE HIGH PRESSURE AND UPPER RIDGING IS BRINGING
RELATIVELY BENIGN WEATHER. FOG IS NOT FORECAST TONIGHT/SATURDAY
MORNING DESPITE GRADUAL INCREASE IN LOW LEVEL MOISTURE, MAINLY
DUE TO LOWEST LEVEL WINDS FORECAST TO BE JUST HIGH ENOUGH .
THIS INCREASE IN MOISTURE COMES AHEAD OF UPPER TROUGHING INTO
THE NORTHERN ROCKIES AND NORTHERN PLAINS/UPPER MIDWEST THIS
WEEKEND. THE INCREASE IN LOW LEVEL MOISTURE AND INCREASED
FORCING ALOFT WILL PROMOTE LIGHT RAIN/DRIZZLE INTO OUR AREA
SATURDAY, FOLLOWED BY CHANCE FOR RAIN SHOWERS AND A FEW
THUNDERSTORMS SATURDAY NIGHT INTO SUNDAY.
AHEAD OF THE UPPER TROUGHING AND ATTENDANT SURFACE LOW PRESSURE
WILL BE WELL ABOVE AVERAGE TEMPERATURES ALOFT. THIS WILL
TRANSLATE OVER OUR AREA BRINGING ABOVE AVERAGE TEMPERATURES
SUNDAY WITH HIGH TEMPERATURES FORECAST AS HIGH AS THE 60S AND
70S.
THIS BEGINS A RELATIVELY LENGTHY PERIOD OF SOUTHWESTERLY/QUASI-
ZONAL FLOW ALOFT, PROMOTING A MORE UNSETTLED WEATHER PATTERN.
SEVERAL SHORTWAVE TROUGHS WILL BE EMBEDDED WITHIN THIS UPPER
REGIME, ALTHOUGH THERE REMAIN SOME UNCERTAINTY IN EXACTLY HOW
EACH OF THESE SHORTWAVE TROUGHS EVOLVE. MORE DETAILS ON THIS CAN
BE FOUND BELOW.
THE COMBINATION OF LENGTHY WELL ABOVE FREEZING TEMPERATURES AND
UPCOMING PRECIPITATION CHANCES WILL CONTRIBUTE TO CHANCE FOR
MINOR RIVERINE FLOODING FOR A FEW TRIBUTARIES IN MINNESOTA. MORE
DETAILS ON THIS BELOW.
..UNSETTLED WEATHER PATTERN AHEAD
ENSEMBLES ALL AGREE IN THE UPPER PATTERN REMAINING IN THIS
SOUTHWESTERLY AND QUASI-ZONAL FLOW REGIME THIS WEEKEND THROUGH
NEXT WEEK. WHILE ENSEMBLES HAVE SOME DISAGREEMENT IN SYNOPTIC
EVOLUTION OF SHORTWAVE TROUGH EVOLUTIONS, THERE ARE A FEW
PERIODS OF NOTE THAT INCREASE OUR RELATIVE CHANCES FOR
PRECIPITATION. THESE PERIODS ARE SATURDAY NIGHT INTO SUNDAY,
TUESDAY, AND LATE NEXT WORK WEEK.
EACH OF THESE WILL BRING THEIR OWN WAVE OF INSTABILITY WITHIN
ITS WARM SECTOR LARGELY DISPLACED FROM OUR AREA. HOWEVER,
CONVECTION FED BY THIS WARM SECTOR MAY BE WITHIN OUR AREA,
INTRODUCING THUNDERSTORMS INTO THE FORECAST.
AS OF NOW, MOST ENSEMBLE GUIDANCE GENERALLY AGREES THAT
MORE SIGNIFICANT PRECIPITATION AMOUNTS OVER 2 INCHES WILL REMAIN
WELL TO OUR WITHIN EASTERN MN INTO WI. STILL, THERE IS A LOW TO
MEDIUM CHANCE FOR 1-2 INCHES WITHIN MINNESOTA AND LOCATIONS
NORTH OF US HIGHWAY 2 BY END OF THE WORK WEEK.
THE LATE WEEK SHORTWAVE TROUGH PASSAGE MAY FEATURE COLD ENOUGH
AIR FOR SOME OF ITS PRECIPITATION TO BE SNOW, OF WHICH MAY BE
ENOUGH TO ACCUMULATE. HOWEVER, DETAILS ON THIS POTENTIAL IS VERY
LIMITED DUE TO LONGER EXTENT INTO THE FORECAST PERIOD.
...WARM TEMPERATURES AND ERODING SNOWPACK BRINGS CHANCE FOR
RIVERINE FLOODING...
DUE TO THE EXTENDED PERIOD OF WELL ABOVE FREEZING TEMPERATURES
OVER THE NEXT SEVERAL DAYS, CONFIDENCE FOR A GREATLY ERODING
SNOWPACK IS HIGH. THERE REMAINS WIDESPREAD FROZEN AND/OR
SATURATED SOILS, WITH SEVERAL AREAS STILL SEEING STANDING WATER
IN OPEN FIELDS (AS SEEN FROM WEBCAMS AND SATELLITE IMAGERY).
THIS LENDS CONFIDENCE THAT EXISTING WATER CONTENT WITHIN THE
SNOWPACK WILL LARGELY RUNOFF INTO RIVERS/TRIBUTARIES.
THE CURRENT WATER CONTENT WITHIN THE SNOWPACK ISN'T VERY HIGH,
AND ALONE WILL LIKELY NOT PUSH RIVERS/TRIBUTARIES INTO FLOOD
STAGE. HOWEVER, THE COMBINATION OF THIS OCCURING WITH UPCOMING
CHANCES FOR ADDITIONAL PRECIPITATION INTRODUCE A MEDIUM CHANCE
FOR MINOR RIVERINE FLOODING. THIS IS MAINLY TIED TO MINNESOTA
TRIBUTARIES WITH CURRENT PRECIPITATION CHANCES RELATIVELY
HIGHEST IN MINNESOTA.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1241 PM CDT FRI APR 10 2026
OVERALL, THE CHANCE FOR AVIATION IMPACTS IS LOW, WITH THE
EXCEPTION OF LLWS DEVELOPING SATURDAY.
SCATTERED TO BROKEN CUMULUS CLOUDS AROUND 3 TO 6 KFT OVER SITES
LIKE KTVF, KGFK, AND KBJI ARE FORECAST BEFORE 00Z. EVENTUALLY
WIDESPREAD MVFR TO IFR CEILINGS ENTER THE REGION MID TO LATE
DAY SATURDAY, WHICH IS JUST BEYOND THIS TAF PERIOD.
WINDS WILL BE GENERALLY BE AROUND 5-10KT OUT OF THE
WEST BEFORE 00Z, AFTERWARDS THEY LESSEN AND TURN OUT OF THE
NORTH AND/OR GO LIGHT AND VARIABLE. AFTER 12Z, WINDS INCREASE
OUT OF THE SOUTH. TOWARD MID TO LATE MORNING SATURDAY, WINDS MAY
BECOME GUSTY 20-30KT.
LOW LEVEL WIND SHEAR IS FORECAST SITES LIKE KFAR AND KTVF AFTER
10Z SATURDAY, BUT MAY ALSO DEVELOP OVER KBJI AND KGFK AS WELL.
