AREAS AFFECTED...PORTIONS OF SOUTHERN/EASTERN OKLAHOMA...WESTERN
ARKANSAS...NORTHEAST TEXAS
CONCERNING...SEVERE THUNDERSTORM WATCH 372...
VALID 220821Z - 221015Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 372
CONTINUES.
SUMMARY...DAMAGING THUNDERSTORM WINDS WILL REMAIN POSSIBLE AS A
WELL-DEVELOPED BOWING COMPLEX OF SEVERE STORMS CONTINUES TO MOVE
EAST/SOUTHEAST. THE SEVERE RISK WILL LIKELY EXTEND BEYOND WW 372
AFTER 09-10Z, AND A DOWNSTREAM WATCH WILL BE NEEDED.
DISCUSSION...A LONG-LIVED AND MATURE BOW ECHO CONTINUES TO MOVE
EAST/SOUTHEAST AT AROUND 45 MPH ACROSS SOUTHERN/EASTERN OK AS OF
0820Z. NUMEROUS REPORTS OF SEVERE WIND GUSTS HAVE BEEN RECEIVED
DURING THE EARLY MORNING ACROSS OK, WITH THE MOST RECENT REPORTS
GENERALLY IN THE 60 TO 70 MPH RANGE. AIDED BY A WELL-DEVELOPED COLD
POOL, EVIDENCED BY A 7 MB PRESSURE RISE AT THE NORMAN MESONET AS THE
SYSTEM MOVED THROUGH CENTRAL OKLAHOMA, SEVERE WIND GUSTS IN THE 60
TO 70 MPH RANGE, WITH ISOLATED HIGHER GUSTS, WILL REMAIN LIKELY AS
THE LEADING EDGE APPROACHES THE SOUTHERN/EASTERN EDGES OF WW 372 IN
THE 09-10Z TIME FRAME. GIVEN THE WELL-ORGANIZED STRUCTURE OF THE MCS
AND A FAVORABLE DOWNSTREAM THERMODYNAMIC ENVIRONMENT (MUCAPE
AVERAGING 3000 J/KG), THE SEVERE WIND RISK IS EXPECTED TO MOVE INTO
WESTERN AR/NORTHEAST TX, AND A DOWNSTREAM SEVERE THUNDERSTORM WATCH
WILL BE COORDINATED.
