AREAS AFFECTED...PORTIONS OF SWRN THROUGH NERN MN...NWRN WI

CONCERNING...SEVERE THUNDERSTORM WATCH 503...

VALID 062329Z - 070130Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 503
CONTINUES.

SUMMARY...THE RISK FOR DAMAGING WINDS AND LARGE HAIL CONTINUES
ACROSS THE WATCH AREA...AND IS INCREASING ACROSS SOUTHERN PORTIONS
OF THE WATCH WHERE THE AIR MASS HAS RECOVERED IN THE WAKE OF EARLIER
STORMS.

DISCUSSION...STRONG/SEVERE THUNDERSTORMS CONTINUE IN PROXIMITY TO A
COLD FRONT THAT CONTINUES MOVING EAST ACROSS WESTERN/CENTRAL
MINNESOTA AT 2325Z. THE MOST INTENSE STORMS WERE OVER ST. LOUIS AND
AITKIN COUNTIES AND APPEAR CAPABLE OF SEVERE HAIL AND WIND GUSTS. A
CORRIDOR OF MODERATE-STRONG MLCAPE EXISTS AHEAD OF THE FRONT...AND
MESOANALYSIS AND AREA VWP DATA SUGGEST SOUTHWESTERLY DEEP-LAYER
SHEAR OF 35-40KTS. A MIX OF SEMI-DISCRETE CELLS AND SHORT LINE
SEGMENTS APPEAR LIKELY TO CONTINUE INTO THE EARLY EVENING WITH A
CONTINUED SEVERE THREAT.

FARTHER SOUTH...THE ATMOSPHERE HAS RECOVERED IN THE WAKE OF EARLIER
STORMS ACROSS THE SOUTHERN PORTION OF THE WATCH /RECENTLY LOCALLY
EXTENDED INTO THE TWIN CITIES AREA/ AND THUNDERSTORMS HAVE BEEN
GRADUALLY BECOMING BETTER ORGANIZED ALONG A LINE FROM NEAR ST CLOUD
TO REDWOOD FALLS. A FAVORABLE DOWNSTREAM ENVIRONMENT EXISTS FOR
ISOLATED TO WIDELY SCATTERED SEVERE STORMS WITH DAMAGING GUSTS AND
HAIL THROUGH 03Z.
