THURSDAY TO 1 AM FRIDAY PERIOD SNOWFALL GENERALLY 2 TO 4
INCHES RRV AND EAST...LOCALLY HIGHER NEAR BEMIDJI.
- THE SECOND ROUND OF SNOW MOVES THROUGH FRIDAY INTO SATURDAY.

UPDATE
ISSUED AT 102 PM CDT THU APR 2 2026
PORTIONS OF THE SOUTHERN RED RIVER VALLEY AND WEST CENTRAL MN
ARE SEEING A BREAK IN SNOW AS THE DRY SLOT MOVES IN. HOWEVER,
MORE SNOW AND MIXED PRECIPITATION BEHIND IT. DURING THE DAYTIME
HOURS, IMPACTS ON PAVEMENT HAVE BEEN FAIRLY MINIMAL, BUT THAT
WILL CHANGE AS THE SUN STARTS TO GO DOWN. WILL KEEP THE WINTER
WEATHER ADVISORY GOING AS THERE COULD BE CONTINUED MINOR IMPACTS
THIS EVENING BEFORE SNOW TAPERS OFF FROM WEST TO EAST AFTER
MIDNIGHT.
ADDITIONALLY, PUT OUT THE WARNINGS AND ADVISORIES FOR THE
FRIDAY/SATURDAY SYSTEM. CONFIDENCE IS GROWING IN A LARGE SWATH
OF 6 TO 12 INCHES ACROSS ALL BUT FAR NORTHEASTERN ND AND THE
NORTHERN RED RIVER VALLEY. A FEW OF THE OUTLIER ENSEMBLE RUNS
EVEN HAVE 15 TO 17 INCHES, BUT THAT SEEMS A BIT OVERDONE.
UPGRADED MUCH OF THE WATCH TO WARNING, WITH SOME ADVISORY
COUNTIES SURROUNDING THE WARNING. MORE DETAILS IN THE NEXT AFD
UPDATE.

DISCUSSION

..SYNOPSIS
THE FIRST OF TWO SYSTEMS WILL BE IMPACTING THE REGION LATER THIS
EVENING AND OVERNIGHT INTO THURSDAY. H5 LOW PRESSURE IS CURRENTLY
MOVING OUT OF NORTHERN UTAH AND INTO NORTHWESTERN COLORADO. THIS
SYSTEM ENTERS THE CENTRAL PLAINS THIS AFTERNOON BEFORE ACCELERATING
NORTHEASTWARD INTO THE NORTHERN PLAINS AND UPPER MIDWEST. AS THIS IS
HAPPENING, A SECOND UPPER LOW MOVES ONSHORE IN THE PACIFIC
NORTHWEST, DIVING TO THE EAST AND SOUTHEAST ON THURSDAY, THEN INTO
THE NORTHERN REACHES OF THE INTERMOUNTAIN WEST OVERNIGHT THURSDAY
INTO FRIDAY MORNING. THIS SECOND LOW WILL DEEPEN QUICKLY AS IT
TRAVELS EAST ON FRIDAY, THEN OCCLUDE AND DRIFT TO THE NORTHEAST
FRIDAY EVENING AND OVERNIGHT INTO SATURDAY MORNING. THE TIMING OF
THIS SLOWDOWN AND INFLECTION WILL GREATLY IMPACT OVERALL SNOWFALL
EXPECTATIONS, AS THE SYSTEM IS EXPECTED TO SPEED BACK UP AS IT
MOVES OFF TO THE NORTHEAST EARLY SATURDAY MORNING.
..FIRST ROUND OF SNOW TONIGHT INTO THURSDAY
THE FIRST SYSTEM WILL BRING ADVISORY CONDITIONS TO MOST OF WEST
CENTRAL MINNESOTA, NORTHWEST MINNESOTA, AND PARTS OF THE SOUTHERN
RED RIVER VALLEY AND SOUTHEAST NORTH DAKOTA. THERE HAS BEEN GOOD
AGREEMENT OVER THE PAST SEVERAL DAYS, BOTH IN THE ENSEMBLES AND
DETERMINISTIC GUIDANCE, REGARDING THE OVERALL TRACK AND INTENSITY OF
THIS FIRST UPPER LOW. THE HEAVIEST SNOWFALL IS EXPECTED ALONG AND
SOUTH OF A LINE FROM JAMESTOWN TO BEMIDJI, WHERE THE 25TH AND 75TH
PERCENTILE AMOUNTS ARE 2" TO 5" RESPECTIVELY. FURTHER NORTH, 1" TO
3" WILL BE POSSIBLE WITH THE FIRST SYSTEM (ALSO 25TH AND 75TH
PERCENTILES). TEMPERATURES WILL ALSO PLAY A ROLE IN HOW MUCH SNOW IS
ABLE TO ACCUMULATE, GIVEN THE RELATIVELY WARM AIR THAT WILL BE IN
PLACE DURING THE EVENT. OVERNIGHT LOWS TONIGHT FALL SLOWLY INTO THE
UPPER 20S TO NEAR 30 DEGREES, THEN WARM DURING THE DAY THURSDAY TO
NEAR FREEZING.
..SECOND ROUND OF SNOW FRIDAY EVENING THROUGH SATURDAY AFTERNOON
LOOKING INTO FRIDAY AND SATURDAY, THE SECOND UPPER LOW MOVES EAST
AND NORTHEAST INTO THE NORTHERN PLAINS AND UPPER MIDWEST AS IT
OCCLUDES AND SLOWS DOWN SLIGHTLY. AS THIS INFLECTION OCCURS, A
PERIOD OF HEAVY SNOW IS LIKELY ALONG THE NORTHERN AND WESTERN SIDE
OF THE LOW. THERE WILL BE PLENTY OF MOISTURE AVAILABLE FOR THE
SECOND SYSTEM AS 1000MB TO 850MB MIXING RATIOS CLIMB WELL INTO THE 3-
4 G/KG RANGE AS THE SYSTEM OCCLUDES JUST EAST OF THE CWA. THIS,
ALONG WITH GOOD BANDING SUPPORT, WILL ALLOW FOR SNOWFALL RATES
UPWARDS OF 1+ INCHES PER HOUR AT TIMES. THE MAIN UNCERTAINTY WITH
THIS SECOND SYSTEM WILL BE RESIDENCE TIME AS THE OCCLUSION HAPPENS,
AND WHETHER OR NOT THE OVERALL FORWARD MOVEMENT OF THE SYSTEM IS
IMPACTED. A STRONGER INFLECTION WILL ALLOW HIGHER TOTALS UPWARDS OF
THE 90TH PERCENTILE, OR UP TO ABOUT 8"-10" OF SNOW IN SOME PLACES.
IF WE SEE FASTER MOVEMENT, AND A WEAKER INFLECTION, THERE WILL BE
FEWER BANDS AND LESS RESIDENCE TIME, THUS SUPPORTING AMOUNTS CLOSER
TO THE 10TH-25TH PERCENTILE IN THE 3"-6" RANGE. THIS WILL BE IN
ADDITION TO THE FIRST SYSTEM, NOT TAKING INTO ACCOUNT ANY COMPACTION
OR MELTING. MUCH LIKE THE FIRST SYSTEM, TEMPERATURES WILL BE NEAR
FREEZING OR JUST BELOW FREEZING FRIDAY NIGHT, THEN CLIMB SLIGHTLY
AFTER SUNRISE ON SATURDAY.
OVERALL POTENTIAL STORM TOTALS (TONIGHT THROUGH SATURDAY), COULD
RANGE ANYWHERE FROM 5" NEAR DEVILS LAKE, TO A FOOT OF SNOW IN THE
VALLEY CITY AREA. IT IS WORTH NOTING THAT THIS WILL BE A VERY HEAVY
AND WET SNOW DUE TO THE TEMPERATURES BEING RELATIVELY WARM.
