NWS STORM PREDICTION CENTER NORMAN OK
0743 PM CDT SAT MAR 14 2026
AREAS AFFECTED...CENTRAL TO NORTHERN WYOMING
CONCERNING...SNOW SQUALL
VALID 150043Z - 150445Z
SUMMARY...RAPIDLY FALLING TEMPERATURES, STRONG WINDS, AND MODERATE
SNOWFALL BEHIND A SHARP COLD FRONT ARE YIELDING BRIEF
BLIZZARD/SNOW-SQUALL CONDITIONS ACROSS NORTH-CENTRAL WYOMING. THESE
CONDITIONS MAY PERSIST AND SPREAD INTO CENTRAL AND EASTERN WYOMING
OVER THE NEXT FEW HOURS.
DISCUSSION...RECENT RADAR MOSAICS SHOW A COLD FRONT RAPIDLY PUSHING
SOUTHWARD TO THE WEST OF THE BIG HORN MOUNTAINS IN NORTH-CENTRAL WY.
SURFACE OBSERVATIONS BEHIND THE FRONT HAVE REPORTED TEMPERATURES
FALLING FROM THE LOW 50S AND UPPER 40S TO BELOW FREEZING WITHIN AN
HOUR. CONCURRENTLY, STRONG LOW-LEVEL COLD ADVECTION (COUPLED WITH
STRONG BACKGROUND GRADIENT WINDS) IS YIELDING FREQUENT POST-FRONTAL
WIND GUSTS OF 30-50 MPH. THIS COMBINATION OF RAPIDLY FALLING
TEMPERATURES, STRONG WIND GUSTS, AND THE DEVELOPMENT OF LIGHT TO
MODERATE SNOW SHOWERS WITHIN THE FRONTAL ZONE IS YIELDING PERIODS OF
VISIBILITY REDUCTIONS BETWEEN 1/2 TO 1/4 MILE BASED ON REGIONAL
ASOS/AWOS REPORTS AND WEB CAMS.
THE COLD FRONT IS EXPECTED TO CONTINUE PUSHING SOUTH/SOUTHEAST OVER
THE NEXT SEVERAL HOURS AS A CYCLONE CONTINUES TO INTENSIFY TO THE
EAST OVER THE HIGH PLAINS. LIGHT TO MODERATE SNOW SHOWERS WILL ALSO
SPREAD TO THE SOUTHEAST, WHICH MAY RESULT IN A RAPID ONSET OF
FLASH-FREEZE CONDITIONS AND SUDDEN VISIBILITY REDUCTIONS UNDER THE
HEAVIER SNOW SHOWERS ACROSS CENTRAL TO EAST-CENTRAL WY WHERE
TEMPERATURES ARE CURRENTLY ABOVE FREEZING.
