WITH LINE OF STRONG TO SEVERE STORMS EXTENDING FROM JUST WEST OF QUINCY TO SPRINGFIELD...IN SOUTHWEST MISSOURI. THIS WILL BE THE MAIN FOCUS IN THE SHORT TERM. BOTH 00Z NAM AND GFS CONTINUE TO WASH OUT FRONTAL BOUNDARY THIS MORNING...BUT KEEP VIGOROUS SHORTWAVE SLIDING NORTHEASTWARD THROUGH THE REGION.

HAVE PLENTIFUL MOISTURE...MODERATE INSTABILITY...BUT WEAK LAPSE RATES AND LACK OF LARGE SCALE SUPPORT...SO SPC HAS DOWNGRADED MODERATE RISK TO SLIGHT RISK FOR ENTIRE CWA TODAY AND TONIGHT. WILL SEE HIGHER POPS SHIFT FURTHER TO THE EAST AND SOUTH OVER CWA BY THIS AFTERNOON. AS FOR TEMPS...EXPECT COOLER CONDITIONS IN THE WEST DUE TO RAIN AND CLOUDS WITH HIGHS ONLY IN THE MID 80S WHILE FAR EASTERN SECTIONS COULD REACH UPPER 80S TO AROUND 90.

FOR SATURDAY NIGHT THROUGH REST OF FORECAST PERIOD...BOUNDARY TO REMAIN NEARBY WITH SERIES OF STRONG SHORTWAVES MOVING FROM THE ROCKIES/CENTRAL PLAINS TO THE WESTERN GREAT LAKES THROUGH NEXT WEEK...DRAGGING THE FRONTAL BOUNDARY FURTHER SOUTH AND INCREASING OUR CHANCES OF THUNDERSTORMS.
