NWS STORM PREDICTION CENTER NORMAN OK
0450 PM CDT THU MAR 12 2026
AREAS AFFECTED...NORTHEASTERN NORTH DAKOTA...NORTHERN
MINNESOTA...NORTHERN WISCONSIN
CONCERNING...HEAVY SNOW
VALID 122150Z - 130145Z
SUMMARY...HEAVY SNOW WILL OVERSPREAD PORTIONS OF NORTHEASTERN NORTH
DAKOTA, NORTHERN MINNESOTA, AND NORTHERN WISCONSIN TONIGHT WITH
SNOWFALL RATES LIKELY RANGE 1-2 INCHES PER HOUR AT TIMES.
DISCUSSION...A DEEPENING SURFACE LOW WILL SHIFT SOUTHEASTWARD FROM
NORTH DAKOTA INTO SOUTHERN MINNESOTA THIS AFTERNOON INTO TONIGHT.
STRONG LOW-LEVEL WARM AIR ADVECTION WITHIN THE 900-700 MB LAYER
AIDED BY DCVA AHEAD OF A MID-LEVEL SHORTWAVE TROUGH AND FAVORABLE
JET STREAK DYNAMICS ARE EXPECTED TO COMBINE TO PROMOTE STRONG ASCENT
WITHIN THE DENDRITIC GROWTH ZONE. THIS WILL SUPPORT HEAVY SNOWFALL
ALONG AND NORTH OF THE TRACK OF THE SURFACE LOW, WITH RATES 1-2
INCHES PER HOUR AT TIMES.
A STRONG SURFACE PRESSURE GRADIENT ON THE NORTHWESTERN PERIPHERY OF
THE SURFACE LOW WILL SUPPORT THE POTENTIAL FOR SUSTAINED NORTHERLY
WINDS AT 30 MPH, WITH THE POTENTIAL FOR WIND GUSTS TO 50+ MPH. GIVEN
THIS, BLOWING SNOW IS LIKELY, WITH BRIEF PERIODS OF BLIZZARD
CONDITIONS POSSIBLE, ESPECIALLY ACROSS THE NORTHERN RED RIVER VALLEY
LATE THIS EVENING.
