NWS STORM PREDICTION CENTER NORMAN OK
0123 PM CDT SAT APR 11 2026
AREAS AFFECTED...PORTIONS OF NORTHERN UTAH INTO FAR SOUTHEAST
IDAHO...EXTREME NORTHWESTERN COLORADO...SOUTHWESTERN WYOMING
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 111823Z - 112030Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A FEW SEVERE GUSTS MAY OCCUR WITH THE STRONGER STORMS THIS
AFTERNOON, AND AN INSTANCE OR TWO OF HAIL CANNOT BE COMPLETELY RULED
OUT. SEVERE THREAT SHOULD REMAIN ISOLATED.
DISCUSSION...THUNDERSTORMS HAVE BEEN GRADUALLY INCREASING IN
COVERAGE AND INTENSITY AS A PRONOUNCED MID-LEVEL VORTICITY MAXIMUM
OVERSPREADS THE CENTRAL ROCKIES, MAXIMIZING DEEP-LAYER ASCENT IN THE
PROCESS. BREAKS IN THE CLOUDS HAVE ALLOWED FOR ADEQUATE SURFACE
HEATING AND DESTABILIZATION, WITH THE 18Z SLC OBSERVED SOUNDING
SHOWING 8+ C/KM TROPOSPHERIC LAPSE RATES, YIELDING TALL, THIN CAPE
PROFILES (WITH OVER 500 J/KG SBCAPE NOTED). FURTHERMORE, THE
OBSERVED SOUNDING DEPICTS A RELATIVELY ELONGATED, STRAIGHT
HODOGRAPH, WITH OVER 30 KTS OF EFFECTIVE BULK SHEAR. AS SUCH,
MULTICELL STORMS SHOULD CONTINUE TO DEVELOP THROUGH THE AFTERNOON. A
68 MPH THUNDERSTORM WIND GUST WAS OBSERVED IN RICH COUNTY, UT, AND
ADDITIONAL SEVERE GUSTS WILL REMAIN THE PRIMARY THREAT THROUGH THE
AFTERNOON. AN INSTANCE OR TWO OF HAIL MAY ALSO OCCUR. OVERALL, THE
SEVERE THREAT SHOULD REMAIN ISOLATED, SO A WW ISSUANCE IS NOT
CURRENTLY EXPECTED.
