0810 PM CDT MON AUG 26 2013

AREAS AFFECTED...N CNTRL MINNESOTA INTO NRN WISCONSIN

CONCERNING...SEVERE THUNDERSTORM WATCH 497...

VALID 270110Z - 270245Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 497
CONTINUES.

SUMMARY...THE RISK FOR DAMAGING CONVECTIVELY GENERATED WIND GUSTS
CONTINUES WITH ONGOING STORMS...AND THIS THREAT MAY STILL INCREASE
ACROSS PARTS OF NORTH CENTRAL MINNESOTA AND NORTHERN WISCONSIN
DURING THE NEXT FEW HOURS.

DISCUSSION...CLOUD TO GROUND LIGHTNING DATA AND SATELLITE IMAGERY
INDICATE THAT THE SMALL LEAD STORM CLUSTER NOW PROGRESSING SOUTH OF
THE DULUTH AREA INTO NORTHWESTERN WISCONSIN IS MAINTAINING
STRENGTH...WITH PERHAPS SOME RECENT INCREASE IN INTENSITY. IN THE
PRESENCE OF STRONG DEEP LAYER SHEAR AND LARGE CAPE...SUPPORTED BY AT
LEAST A NARROW CORRIDOR OF HIGH PRECIPITABLE WATER...DAMAGING WIND
POTENTIAL STILL COULD INCREASE WITH THIS ACTIVITY AS IT SPREADS
ACROSS THE HAYWARD VICINITY INTO AREAS NEAR/SOUTHWEST OF RHINELANDER
THROUGH THE 02-04Z TIME FRAME.

MEANWHILE ISOLATED UPSTREAM STORM TO THE WEST OF BRAINERD REMAINS
STRONG/SEVERE...AND IT DOES NOT APPEAR OUT OF THE QUESTION THAT
ENHANCED FORCING FOR ASCENT ON THE NOSE OF A STRENGTHENING 850 MB
JET COULD SUPPORT A GROWING STORM CLUSTER NORTH THROUGH NORTHEAST OF
ST. CLOUD.
