COUPLED JET STRUCTURE ARRIVES OVERHEAD AND 850-700MB MOISTURE
TRANSPORT NOSES INTO THE AREA. AN ASSOCIATED STRONG PV FEATURE
ALSO CONTINUES TO BE PROGGED BY THE MAJORITY OF MODEL SOLUTIONS.
HAVE GONE WITH CATEGORICAL POPS OVER MUCH OF THE AREA FOR LATE
TONIGHT INTO THURSDAY MORNING. ALTHOUGH THE SEVERE THREAT APPEARS
LOW...A FEW STORMS COULD PRODUCE HAIL IN WEST CENTRAL MINNESOTA
TONIGHT WHERE LAPSE RATES ARE MARGINAL...AND ON THURSDAY AFTERNOON
AS THE MID LEVEL TROUGH PASSES.

A FEW SHOWERS MAY DEVELOP OVER EASTERN AREAS /MAINLY WEST CENTRAL
WI/ ON FRIDAY PRIOR TO THE COMPLETE DEPARTURE OF THE TROUGH. COLD
AIR ADVECTION WILL RESULT AND TEMPERATURES WILL TOP OUT IN THE
60S...OR AROUND 10 DEGREES BELOW NORMAL FOR EARLY SEPTEMBER.

RIDGING BUILDS IN FOR THE WEEKEND...WITH DRY WEATHER AND VERY
GRADUALLY MODERATING TEMPERATURES. BY SUNDAY...HIGHS SHOULD REACH
THE 70 TO 75 DEGREE RANGE CWA-WIDE.

LOW 80S RANGE. ALTHOUGH THERE IS STILL SOME UNCERTAINTY WITH THE
LOW TRACK...THE 18Z MONDAY TO 18Z TUESDAY TIME FRAME APPEARS TO BE
THE WINDOW OF OPPORTUNITY FOR MEASURABLE PRECIPITATION.
