MESOETA DEPICTS HEALTHY 500MB VORT IN THERMAL TROF PASSING THROUGH THIS AFTERNOON IN UNSTABLE ATMOSPHERE. SOUNDINGS SHOW CAP WEAKENING THIS AFTERNOON AND 700MB TEMPS COOL OFF A FEW DEGREES. SMALL 850MB JETLET REVS UP OVER NORTHN INDIANA THIS AFTERNOON AS WELL. POSSIBLE OUTFLOW BOUNDARIES AND AREA OF THUNDERSTORMS EXTENDING FROM SOUTHERN WISCONSIN TO CENTRAL MISSOURI AT 16Z MOVING STEADILY EAST ARE ADDITIONAL FACTORS.

THIS SYSTEM SHOULD REACH LAPORTE/BEH BETWEEN 830 AM EST AND 10 AM ACCORDING TO STORM PROGS. AS WITH YESTERDAY...APPEARS DERECHO PATTERN INDICATED WITH A STRONG POSSIBILITY OF DAMAGING WINDS. AHEAD OF THIS SYSTEM...OUTFLOW BOUNDARY HAD PUSHED SOUTH TO ABOUT A WINAMAC TO FWA LINE AND HAD BECOME STATIONARY. ANOTHER OUTFLOW FROM STORMS OVER LAKE MI SHOULD STRENGTHEN THIS LEADING BOUNDARY...AND PROVIDE AN ADDITIONAL TRIGGER FOR STORMS TODAY. HAVE EXTENDED FLOOD WATCH FOR TODAY OVER FAR SOUTHWEST LOWER MI AND ABOUT 2 TIERS DEEP IN N INDIANA AND NW OH. ALTHOUGH STORMS SHOULD HAVE RELATIVELY FAST MOVEMENT...EXPECT SOME TRAINING OVER AREAS THAT HAVE RECEIVED HEAVY RAINFALL LAST COUPLE OF DAYS. NCEP MODELS HAVING HARD TIME HANDLING LOCATION OF FRONT WITH MODIFICATION OF AIRMASS AND OUTFLOW BOUNDARIES. LAST COUPLE OF DAYS...ETA WAS TRYING TO MOVE THE FRONT TOO FAR NORTH...SO AM HESITANT TODAY TO BUY SAME PATTERN INDICATED BY THE ETA...SO WENT IN THE NORTH...MI...WITH HIGHER POPS THERE. 00Z ILX SOUNDING SHOWING FAIRLY SOLID CAP THAT WAS HOLDING CONVECTION OVER SOUTHERN AREAS MORE IN CHECK.
