AREAS AFFECTED...NORTHERN NE AND SOUTHERN SD
CONCERNING...SEVERE THUNDERSTORM WATCH 572...
VALID 120602Z - 120730Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 572
CONTINUES.
SUMMARY...A MATURING BOW WILL CONTINUE TO YIELD A RISK FOR
HIGHER-END WIND POTENTIAL OVER THE NEXT 1-2 HOURS AS IT MOVES INTO
NORTHERN PORTIONS OF NE.
DISCUSSION...LATEST RADAR IMAGERY FROM KFSD/KUDX SHOWS A POTENT
CLUSTER EVOLVING INTO A MATURING BOW ALONG THE NE/SD BORDER WITH
ECHO TOPS INCREASING IN THE PAST 30 MINUTES TO 60 KFT. THE AIRMASS
REMAINS VERY UNSTABLE PER RAP FORECAST SOUNDINGS (AROUND 4000 J/KG
MUCAPE) WITH MODEST LOWER TO MID-LEVEL FLOW (20-25 KT) INCREASING TO
60 KT AROUND 250 MB. THIS THERMODYNAMIC/KINEMATIC ENVIRONMENT WILL
CONTINUE TO STRONGLY FAVOR SEVERE GUSTS AND A CONTINUATION OF THE
MATURE PHASE OF THE BOW ECHO THROUGH AT LEAST 2-3AM CDT. RECENTLY
MEASURED GUSTS IN THE 90-95 MPH RANGE IN SOUTHERN SD ARE INDICATIVE
OF THE HIGHER-END WIND POTENTIAL.
