THE CWFA WILL REMAIN IN A MOIST AND UNSTABLE AIRMASS THROUGHOUT THE DAY. WATER VAPOR AND RUC ANALYSIS DEPICTED A WEAK VORT MAX NEAR THE LOWER OHIO VALLEY. BAGGY H5 MID LVL TROF OVER THE CNTRL PLAINS WILL CONT TO DIG SE TODAY. SW FLOW ON THE EAST SIDE OF THE TROF AXIS WILL PIVOT THIS WEAK VORT MAX INTO THE SWRN CWFA DURING THE MORNING HOURS.

BELIEVE THIS ACTIVITY WILL PIVOT INTO THE SWRN CWFA THIS AM...BUT SHOULD NOT BE AS WIDESPREAD AS THE NGM IS INDICATING.

ALL MODELS SHOW A LACK OF LOW LVL FORCING FROM THE 925 MB TO THE 850 MB. THUS...THUNDERSTORM DEVELOPMENT THIS AFTN WILL BE THE PRODUCT OF UPR DIV AND ANY INSOLATION THAT FILTERS THROUGH. H5 S/WV MOVING ACRS MN/WISC THIS AM IS FCST TO MOVE ACRS MICH DURING THE AFTN.

FOR THE CMH AND PMH AREAS...ACTIVITY WILL BE MORE HEAT GENERATED. PW WATER REMAINS HIGH TODAY (1.5 INCHES). ALTHOUGH STORMS ARE FCST TO MOVE FROM A SW TO W DIRECTION AT ABOUT 10 TO 15 MPH...THIS IS STILL SLOW ENOUGH TO CAUSE LOCALLY HEAVY RAIN. WILL ONCE AGAIN MENTION THIS IN THE ZONES. TEMPS TODAY WILL BE CLOUD DEPENDENT AND WHERE RAIN FALLS. MOS VALUES LOOK REASONABLE GIVEN THE AFOREMENTIONED SCENARIO. FOR TONIGHT...WILL KEEP THREAT FOR SHOWERS AND TSTMS THROUGH ABOUT MIDNIGHT...THEN ACTIVITY SHOULD DIMINISH AS LACK OF INSOLATION AND DEPARTING S/WV WILL TAKE AWAY ANY SUBSTANTIAL LIFT/UPR DIV.
