AREAS AFFECTED...S-CNTRL/SERN ND...FAR NERN SD

CONCERNING...SEVERE THUNDERSTORM WATCH 313...

VALID 200229Z - 200330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 313
CONTINUES.

SUMMARY...DMGG WIND THREAT WILL CONTINUE TO ACCOMPANY A SMALL MCS
MOVING E-SEWD ACROSS SRN ND. SVR TSTM WATCH 313 HAS BEEN LOCALLY
EXTENDED UNTIL 05Z FOR PARTS OF S-CNTRL ND.

DISCUSSION...SMALL MCS CAPABLE OF PRODUCING SIGNIFICANT DMGG WINDS
HAS RECENTLY MOVED THROUGH THE BISMARCK AREA...WITH A MEASURED 82
MPH GUST OBSERVED AT KBIS. RADAR PRESENTATION OF THIS STORM SHOWS A
MATURE BOWING LINE SURGING E-SEWD AT AROUND 50 KT. A STRENGTHENING
LOW-LEVEL JET ACROSS THE CNTRL/ERN DAKOTAS COULD CONTINUE TO SUPPORT
CONVECTIVE SUSTENANCE AND AN ACCOMPANYING DMGG WIND THREAT FOR THE
NEXT COUPLE HRS. HOWEVER...THE BIGGEST LIMITING FACTOR FOR A
LONGER-LIVED AND MORE INTENSE MCS FARTHER E APPEARS TO BE WEAKER
INSTABILITY /PER 00Z ABR SOUNDING/ AND DRIER LOW-LEVEL AIR WITH
MID-UPPER 50S DEWPOINTS OBSERVED ACROSS WRN MN. TRENDS WILL CONTINUE
TO BE MONITORED FOR A POSSIBLE SVR THREAT EXTENDING E OF SVR TSTM
WATCH 313.
