AREAS AFFECTED...WRN DAKOTAS...NWRN NEB

CONCERNING...SEVERE THUNDERSTORM WATCH 710...

VALID 120058Z - 120230Z

TWO MAIN AREAS OF SEVERE STORMS PERSIST...ONE FROM NWRN SD INTO WRN
ND ASSOCIATED WITH SYNOPTIC SCALE LIFT WITH SHORTWAVE TROUGH...AND
ANOTHER OVER FAR S-CNTRL SD INTO NRN NEB...INITIATED BY STRONG
HEATING. THE GAP/LACK OF STORMS OVER CENTRAL AND SWRN SD HAS BEEN
WELL ADVERTISED BY MOST MODELS. THUS...DUE TO INCREASING
CAPPING...ADDITIONAL DEVELOPMENT IS UNLIKELY BETWEEN PIR AND RAP.
HOWEVER...ISOLATED RIGHT MOVING CELL NEAR FAITH SD WILL LIKELY
PERSIST AS IT TRACKS SEWD E OF THE DRYLINE.

FARTHER N...STORMS WILL ALSO PERSIST WITH STRONGER FORCING...AND AN
ADDITIONAL WW MAY BE REQUIRED LATER TONIGHT IF STORMS MAINTAIN
INTENSITY AS THEY CROSS THE MISSOURI RIVER.
