   MESOSCALE DISCUSSION 1078
   NWS STORM PREDICTION CENTER NORMAN OK
   0929 PM CDT FRI JUN 19 2015

   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.
