AREAS AFFECTED...CENTRAL TO SOUTHEAST WYOMING
CONCERNING...SEVERE THUNDERSTORM WATCH 391...
VALID 252046Z - 252245Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 391
CONTINUES.
SUMMARY...THE POTENTIAL FOR SEVERE WINDS WILL CONTINUE INTO
SOUTHEAST WYOMING OVER THE NEXT FEW HOURS. WIND GUSTS BETWEEN 60-70
MPH APPEAR POSSIBLE.
DISCUSSION...A LOOSELY ORGANIZED MCS CONTINUES TO PUSH
EAST/SOUTHEAST ACROSS CENTRAL WY AND HAS A HISTORY OF PRODUCING WIND
GUSTS MOSTLY BETWEEN 35-55 MPH. OVER THE PAST HALF HOUR, GOES IR
IMAGERY HAS SHOWN STEADILY COOLING CLOUD-TOP TEMPERATURES, IMPLYING
A SLOW STRENGTHENING TREND AS THE DOWNSTREAM AIR MASS CONTINUES TO
WARM AND DESTABILIZE. CONSEQUENTLY, OUTFLOW WIND SPEEDS WITH THE MCS
MAY INCREASE INTO THE 60-70 MPH RANGE OVER THE NEXT COUPLE OF HOURS
AS THE BAND MOVES INTO SOUTHEAST WY. BASED ON RECENT VELOCITY
IMAGERY, DOWNSTREAM LOW-LEVEL LAPSE RATES, AND TIME-LAGGED HRRR/RRFS
ENSEMBLES, THE GREATEST WIND THREAT WILL MOST LIKELY EMERGE BETWEEN
THE I-80 TO I-25 CORRIDORS OVER THE NEXT 1-2 HOURS BEFORE THE MCS
BEGINS TO PUSH INTO A COOLER, MORE STABLE AIR MASS IN PLACE ALONG
THE WY/NE BORDER.
