AREAS AFFECTED...NRN MN

CONCERNING...SEVERE THUNDERSTORM WATCH 534...

VALID 270759Z - 270900Z

THREAT OF ISOLATED STRONG WIND GUSTS MAY CONTINUE NEXT COUPLE HOURS
WITH SQUALL LINE OVER NRN MN...BUT OVERALL TREND HAS BEEN FOR STORMS
TO WEAKEN. ACTIVITY SHOULD BEGIN MOVING E OF WW 534 AROUND 0930Z...
BUT IT APPEARS MOST OF THE STORMS WILL SPREAD INTO SRN CANADA AFTER
THIS TIME. IT APPEARS ANOTHER WW E OF 534 WILL NOT BE NECESSARY. 

EARLY THIS MORNING...SQUALL LINE OVER NWRN MN CONTINUES ENEWD AT 45
KT. STORMS HAVE SHOWN A TENDENCY TO WEAKEN DURING THE PAST HOUR AS
THE BOUNDARY LAYER CONTINUES TO STABILIZE. DEVELOPMENT ALONG THE SRN
END OF THE OUTFLOW BOUNDARY HAS BEEN LIMITED DUE TO PRESENCE OF A
STRONGER CAP. WITH THE LOW LEVEL FLOW GRADUALLY VEERING WITH TIME
OVER CNTRL AND SWRN MN AND STRONGER DEEP LAYER FORCING FOR ASCENT
LIFTING NEWD INTO CANADA...IT APPEARS UNLIKELY THAT STORMS WILL BE
ABLE TO DEVELOP MUCH FARTHER SWD. THE OVERALL WEAKENING TREND SHOULD
CONTINUE AS STORMS LIFT NEWD TOWARD A MORE STABLE BOUNDARY LAYER.
