UPDATE
ISSUED AT 957 AM CST SUN NOV 2 2025
LIMITED UPDATES NEEDED THIS MORNING. WINDS ARE SLOWLY STARTING
TO INCREASE AS THE FRONT BEGINS TO MOVE THROUGH. SUSTAINED WINDS
OF 30 MPH ARE STARTING TO BE REPORTED IN THE NORTH, WITH GUSTS
OVER 40 MPH. THUS WILL KEEP THE WIND ADVISORY AS IS AS THESE
WINDS ARE EXPECTED TO BE STRONG WHILE THE FRONT PASSES THROUGH
THIS MORNING THROUGH THIS AFTERNOON. WEAK RADAR RETURNS IN
MONTANA AND IN SOUTHERN CANADA COULD MOVE THROUGH THE NORTH AND
SOUTHWEST TODAY. ABUNDANT DRY AIR WILL LIKELY INHIBIT SHOWER
ACTIVITY TODAY. FOR NOW ADDED IN SOME SPRINKLES FOR THESE
MENTIONED AREAS.
UPDATE
ISSUED AT 642 AM CST SUN NOV 2 2025
CLOUD COVER OVER EASTERN MONTANA CONTINUES TO SHIFT OVER WESTERN
NORTH DAKOTA. FOR EARLY MORNING UPDATE HAVE ADJUSTED CLOUD COVER
TO REFLECT THIS INCREASE.
DISCUSSION
ISSUED AT 224 AM CST SUN NOV 2 2025
CURRENT SURFACE ANALYSIS PLACES SURFACE LOW NEAR THE
SASKATCHEWAN/MANITOBA BORDER, WITH TROUGH/WARM FRONT SLIDING
THROUGH THE WESTERN DAKOTAS. UPPER LEVEL ANALYSIS PLACES LOW
OVER SOUTHEASTERN PORTIONS OF THE MIDWEST, WITH WESTERLY FLOW
OVER OUR AREA. OVER OUR AREA, WINDS HAVE BEEN BECOMING GUSTY
WITH THE PASSING LOW.
FOR TODAY, SURFACE LOW WILL CONTINUE ITS SWIFT PROGRESSION TO
THE EAST PASSING OVER SOUTHERN MANITOBA ENTERING WESTERN ONTARIO
LATER THIS AFTERNOON. WARM FRONT OVER WESTERN NORTH DAKOTA WILL
CONTINUE TO PROCEED EASTERLY, WITH THE COLD FRONT DROPPING
THROUGH LATER THIS MORNING INTO MID-DAY. VERY MILD AIR WILL
MOVE INTO THE AREA IN THE WARM SECTOR, WITH TEMPERATURES ALREADY
CLIMBING INTO THE LOWER TO MID 50S OVER PARTS OF SOUTHWEST
NORTH DAKOTA. WARMEST TEMPERATURES SHOULD OCCUR RIGHT BEFORE
COLD FRONTAL PASSAGE WITH HIGHS EXPECTED TO BE ABOUT 10 TO 15
DEGREES ABOVE AVERAGE. BEHIND THE COLD FRONT, COLD AIR ADVECTION
WILL OCCUR BUT IT IS NOT VERY STRONG. THE MAIN CONCERN, THOUGH,
WILL BE WINDS. ALTHOUGH THE COLD AIR ADVECTION IS MODEST, IT IS
ENOUGH WHERE STRONGER WINDS NOTED ALOFT (~40-45 KTS) SHOULD BE
ABLE TO MIX TO THE SURFACE AS SUGGESTED BY LATEST FORECAST
SOUNDINGS. THEREFORE, HAVE PUT OUT A WIND ADVISORY FOR TODAY FOR
WESTERN AND NORTH CENTRAL NORTH DAKOTA.
FORECAST THEN BECOMES RATHER QUIET THROUGH MID-WEEK AS WE END UP
IN A GENERALLY ZONAL FLOW PATTERN WHICH SHOULD KEEP MAINLY DRY
WEATHER OVER THE REGION AND KEEP TEMPERATURES AROUND OR JUST
ABOVE AVERAGE. LATER IN THE WEEK PATTERN STARTS TO BECOME A BIT
MORE ACTIVE WITH A VARIETY OF WAVES PASSING THROUGH, BRINGING
LOW TO MODERATE CHANCES (ABOUT 20 TO 40 PERCENT) FOR
PRECIPITATION.
