ISSUED AT 940 PM CST FRI NOV 7 2025
LOW IS SLOWLY PUSHING INTO NORTHEAST MONTANA WITH THE LEADING
WARM AIR ADVECTION NOW CENTERED ON A LINE FROM CROSBY ND TO
BISMARCK. SNOW SHOULD START TO INCREASE WEST OF THE RED RIVER
VALLEY WITHIN THE NEXT 6 HOURS, ALTHOUGH THE HEAVIEST SNOWFALL
WILL BE AFTER MIDNIGHT. LIGHTER SNOWFALL MAY SPREAD EAST TOWARDS
THE RED RIVER VALLEY, ALTHOUGH MEANINGFUL ACCUMULATIONS WILL BE
MUCH LESS THAN WEST OF THE VALLEY.

THE LOW STILL REMAINS CENTERED OVER CENTRAL MONTANA WITH THE
LEADING WARM AIR ADVECTION STRETCHING ON A LINE FROM WILLISTON

SNOW BEGINNING AROUND MIDNIGHT ALONG THE WESTERN EDGES OF THE
CWA. NO MAJOR CHANGES TO THIS UPDATE AS TIMING REMAINS ON TRACK
WITH FORECAST.
DISCUSSION
ISSUED AT 222 PM CST FRI NOV 7 2025
..SYNOPSIS
ANOTHER ROUND OF LIGHT SNOW IS POSSIBLE TONIGHT INTO SATURDAY
MORNING AS H5 LOW PRESSURE MOVES SOUTHEAST OUT OF SASKATCHEWAN AND
INTO THE NORTHERN PLAINS. LOOK FOR GENERALLY LIGHT AMOUNTS OF SNOW
FOR AREAS WEST OF THE RED RIVER VALLEY, WITH A FEW SPOTS POSSIBLY
SEEING 1-3 INCHES OF SNOW. MUCH COLDER AIR WILL CONTINUE FLOWING
INTO THE AREA TONIGHT THROUGH SUNDAY, WITH HIGHS BOTH DAYS LIKELY
NOT REACHING THE 30 DEGREE MARK. LOWS EACH MORNING ARE EXPECTED TO
BE IN THE TEENS TO NEAR 20 DEGREES. WARMER TEMPERATURES FOLLOW TO
START NEXT WEEK AS HIGHS REBOUND INTO THE MIDDLE 30S ON MONDAY AND
INTO THE 40S TO NEAR 50 DEGREES ON TUESDAY. THERE ARE MINIMAL
CHANCES FOR PRECIPITATION THROUGH MUCH OF NEXT WEEK.
..SNOW TONIGHT INTO SATURDAY MORNING
H5 SHORTWAVE HAS MOVED EAST OF THE AREA THIS AFTERNOON, WITH AN
UPPER LOW APPROACHING FROM THE NORTHWEST. THIS WILL BE THE SOURCE OF
THE NEXT ROUND OF PRECIPITATION EXPECTED TONIGHT INTO SATURDAY AS IT
INTERACTS WITH A MUCH LARGER H5 LOW, SITUATED JUST SOUTH OF THE
HUDSON BAY. SOUNDINGS INDICATE THE DEVELOPMENT OF A DEEP DGZ THIS
EVENING AND OVERNIGHT, ESPECIALLY FOR PARTS OF THE AREA WEST OF A
LINE FROM DEVILS LAKE TO VALLEY CITY. CAMS DIFFER SLIGHTLY FROM THE
ENSEMBLE SOLUTIONS AT THIS TIME, MAINLY WITH REGARDS TO THE UPPER
LIMIT OF SNOWFALL. THERE IS STRONG ENSEMBLE SUPPORT FOR UP TO ABOUT
1 INCH OF SNOW; HOWEVER, THERE IS INCREASING MESOSCALE SUPPORT FOR
HIGHER AMOUNTS IN THE RANGE OF 1-3 INCHES.
..LAKE EFFECT SNOW AROUND LAKE OF THE WOODS SAT INTO SUN
PERSISTENT NORTH WINDS ARE SET TO IMPACT LAKE OF THE WOODS THIS
WEEKEND, ESPECIALLY SATURDAY EVENING THROUGH SUNDAY. DURING THIS
TIME, COLD AIR WILL BLOW ACROSS THE WARM LAKE WATERS, INCREASING
LAPSE RATES AND ALLOWING PERIODS OF LIGHT TO MODERATE SNOW. AREAS
ALONG THE SOUTHERN SHORE OF THE LAKE WILL SEE THE HIGHEST CHANCES
FOR ACCUMULATION. PERIODS OF LOW VISIBILITY ARE POSSIBLE WITH THESE
SNOW SHOWERS.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
ISSUED AT 531 PM CST FRI NOV 7 2025
SKIES WILL INITIALLY BE MVFR FOR TAF SITES ALONG THE
DAKOTA/MINNESOTA STATE LINES AND EASTWARD, BUT SHOULD JOIN DVL
IN BECOMING VFR OVERNIGHT. WINDS WILL DIMINISH WITH THIS AND
BECOME VARIABLE.
CEILINGS SHOULD BEGIN TO FALL AT DVL AROUND 06Z, ALTHOUGH HOW
LOW THEY BECOME IS IN QUESTION. MOST GUIDANCE PLACES DVL RIGHT
ON THE DIVIDING LINE BETWEEN VFR AND MVFR. AS YOU PROGRESS WEST
OF DVL, CEILINGS WILL CONTINUE TO BE LOWER. THIS CLOUD DECK WILL
PROGRESS SOUTH-SOUTHEASTWARD AND WILL LIKELY PREVENT ANY MVFR
CEILINGS AT ALL OTHER TAF SITES. ACCOMPANYING THIS CLOUD DECK
WILL BE SNOW, BUT THE BULK OF SNOW SHOULD REMAIN WEST OF DVL.
SHOULD SNOW ARISE AT ANY TAF SITE, EXPECT VISIBILITIES TO FALL
TO AT LEAST MVFR WITH A LOW CHANCE FOR IFR.
