WIDE BAND OS SHOWERS AND THUNDERSTORMS WAS SHIFTING EWD THRU THE CWA
EARLY THIS MRNG AHEAD OF THE MID-UPPER LEVEL TROF EXTENDING FROM A MID
LEVEL LOW OVER NWRN MN S TO A STRONG VORT MAX OVER SWRN AR. MOST OF
THIS ACTIVITY WAS ALSO ASSOCIATED WITH LOW LEVEL MOISTURE
CONVERGENCE...WAA AND THETA E ADVECTION ON THE NOSE OF A SWLY LLJ
AND ALONG A PREFRONTAL TROF...OUTFLOW BOUNDARY. THERE WAS MORE
SCATTERED ACTIVITY ALONG OR JUST AHEAD OF THE ACTUAL CDFNT
EXTENDING FROM WI S-SW THRU NERN MO TO SWRN MO. MOST OF THE
PRECIPITATION FOR THE REST OF THE MRNG SHOULD BE ACROSS IL E OF
THE MISSISSIPPI RIVER. WILL HAVE CLEARING FROM W TO E TODAY BEHIND
THE MID-UPPER LEVEL TROF AND ASSOCIATED CDFNT. WILL ALSO HAVE MORE
NORMAL TEMPERATURES TODAY...COOLER THAN THE LAST SEVERAL DAYS DUE
TO CLOUD COVER AND CAA THIS MRNG. TEMPERATURES WILL COOLER TGT AS
WELL MAINLY DUE TO LOWER SFC DEWPOINTS. WELL ABOVE NORMAL
TEMPERATURES CAN BE EXPECTED FOR SUN WITH INCREASING S-SWLY LOW
LEVEL FLOW AND UPPER LEVEL HEIGHTS RISING. ELEVATED CONVECTION
WILL RETURN TO THE CWA BY SUN NGT AS A STRONG SWLY LLJ BRINGS LOW
LEVEL MOISTURE BACK TO THE AREA. THE MODELS ALSO FORECAST A FRONT
TO SAG SWD INTO NRN MO. THERE IS STILL A LOT OF MODEL UNCERTAINTY
WITH THE PLACEMENT OF THE GREATEST QPF SUN NGT AND HOW FAR S THIS
PRECIPITATION WILL GET. THE CHANCE OF SHOWERS/THUNDERSTORMS WILL
CONTINUE MON BUT SHOULD SHIFT MAINLY N OF THE CWA MON NGT AS THE
FRONT SHIFTS N OF THE CWA. SHOWERS/STORMS WILL MOVE THROUGH THE
AREA TUE AFTN AND TUE NGT AS A MID-UPPER LEVEL LOW MOVES NEWD THRU
