445 ACUS11 KWNS 192200 SWOMCD SPC MCD 192200 MNZ000-WIZ000-NDZ000-192330- MESOSCALE DISCUSSION 1900 NWS STORM PREDICTION CENTER NORMAN OK 0500 PM CDT SAT JUL 19 2003 AREAS AFFECTED...CENTRAL/NRN MN...AND ERN/NERN ND CONCERNING...SEVERE THUNDERSTORM WATCH 764... VALID 192200Z - 192330Z WW 764 CONTINUES IN EFFECT ACROSS CENTRAL MN. AN ADDITIONAL SEVERE THUNDERSTORM WATCH MAY BE NEEDED NW OF CURRENT WATCH ACROSS NWRN/NRN MN AND NERN/ERN ND FOR CONVECTIVE STORMS MOVING SEWD FROM SRN MANITOBA. AT 2145Z...SEVERAL SEVERE THUNDERSTORMS WERE LOCATED FROM JUST NW OF STC NWWD TO 30 N AXN. MOVEMENT OF THESE CELLS WAS GENERALLY 330/35 KTS. LOW-LEVEL VEERING / WARM ADVECTION PROFILE PER MINNEAPOLIS VAD SUGGESTS A CONTINUED FEED OF WARM/MOIST INFLOW TO THESE THUNDERSTORMS FROM THE WEST...WHICH SHOULD SUSTAIN STORMS AT OR ABOVE SEVERE LIMITS FOR SEVERAL ADDITIONAL HOURS AS THEY PROGRESS SEWD. LARGE HAIL...AND ISOLATED DAMAGING WINDS WILL BE THE PRIMARY THREAT. ALTHOUGH SURFACE WINDS ARE WEAK...SUPERCELLULAR SHEAR /SFC-6KM SHEAR AROUND 45KT/ AND MOIST VERY MOIST LOW-LEVEL CONDITIONS SUGGEST THE POSSIBILITY OF AN ISOLATED TORNADO. SOME TRAINING OF THUNDERSTORMS ALSO SUGGEST A LOCAL HEAVY RAIN THREAT FROM 35 NE AXN TO 20 S STC THROUGH LATE THIS EVENING. FURTHER UPSTREAM...AN AREA OF THUNDERSTORMS 80N DVL SHOULD TRACK SEWD REACHING FAR NERN ND AROUND 23Z. SUPPORT FROM UPPER TROUGH NORTH OF THESE STORMS AND MOVEMENT OF CELLS INTO MORE UNSTABLE ENVIRONMENT WITH GREATER THAN 40KT DEEP-LAYER SHEAR SUGGESTS AN ADDITIONAL SEVERE THUNDERSTORM WATCH WILL BE NEEDED SOON FOR NERN/ERN ND AND NRN MN. ..BANACOS.. 07/19/2003 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
