AREAS AFFECTED...CNTRL AND ERN ND

CONCERNING...SEVERE THUNDERSTORM WATCH 528...

VALID 260858Z - 261030Z

THREAT OF ISOLATED STRONG WIND GUSTS IS EXPECTED TO CONTINUE NEXT
2-3 HOURS. HOWEVER...A GRADUAL WEAKENING IN OVERALL INTENSITY IS
EXPECTED TO PERSIST. UNLESS STORMS REINTENSIFY...ANOTHER WW E OF 528
IS NOT ANTICIPATED AT THIS TIME.

A SQUALL LINE EXTENDS FROM JUST W OF DEVILS LAKE SWWD TO N OF
BISMARK. NRN PORTION OF LINE IS MOVING THE FASTEST AT AROUND 35 KT
AND WILL BEGIN MOVING E OF WW 528 BY 0945Z. OVERALL TRENDS HAVE BEEN
FOR STORMS TO GRADUALLY WEAKEN. LOW LEVEL JET IS FORECAST TO
GRADUALLY LIFT NWD INTO SRN CANADA DURING THE MORNING WHERE
STRONGEST PRESSURE FALLS ASSOCIATED WITH A NEWD MOVING SHORTWAVE
TROUGH OVER SWRN SASKATCHEWAN EXISTS. THIS SHOULD CONTRIBUTE TO
WEAKENING LOW LEVEL STORM RELATIVE INFLOW AND CONVERGENCE WITH TIME
WHICH...IN CONCERT WITH THE RELATIVELY STABLE BOUNDARY
LAYER...SHOULD MAINTAIN A WEAKENING TREND. HOWEVER...STORMS MAY
PERSIST THROUGH MUCH OF THE MORNING AS A NON-SEVERE MCS. STORMS ON
THE SRN END OF THE MCS MAY GRADUALLY DEVELOP SEWD ALONG THE
INSTABILITY GRADIENT THROUGH CNTRL AND SERN ND.
