FURTHER EAST...PARTLY SUNNY SKIES WILL BE NOTED ACROSS EAST-CENTRAL AND SOUTHEAST ILLINOIS...WITH AN INCREASING CHANCE FOR THUNDERSTORMS AS THE DAY GOES ON. SPC HAS THIS AREA OF ILLINOIS OUTLOOKED FOR POTENTIAL SEVERE LATER TODAY...AND THIS STILL LOOKS GOOD AS THIS WILL BE THE AREA OF GREATEST DESTABILIZATION. BASED ON CURRENT SATELLITE/RADAR LOOPS...AS WELL AS 12Z NAM-WRF/GFS...HAVE INCREASED THE POPS ACROSS THE WESTERN CWA AND DECREASED THEM INTO THE CHANCE CATEGORY FOR THE SOUTHEAST.

SATELLITE TRENDS SHOWING SOME THINNING OUT OF THE CLOUDS BEHIND INVOF THE SHOWERS...HINTING AT THEIR CONTINUED DEMISE. MORE SOLID CONVECTIVE ACTIVITY IN THE SRN PLAINS THIS MORNING. FORECAST ISSUES ARE THE PASSAGE OF THE FRONT LATER TODAY AND THE REFIRING OF CONVECTION...TEMPS...AND ANOTHER SHOT AT PRECIP THURSDAY.

WITH SPEED OF SAID FRONT BEING A BIT OF A QUESTION...ESPECIALLY AS TO HOW QUICKLY STORMS WILL TRANSITION FROM A SW TO NE MOTION...TO A MORE FORWARD MOTION WITH THE FRONT...AND PLENTY OF AVAILABLE MOISTURE...KEEPING THE FFA GOING WITH THE POSSIBILITY OF AREAS OF HEAVY RAIN. HAVE PULLED THE WORDING OUT OF THE GRIDS...THINKING THAT THE EVENT MAY NOT BE AS WIDESPREAD...BUT WITH THE WET GROUND AND SWOLLEN RIVERS...AN FFA IS MORE THAN ACCEPTABLE.
