AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 555 PM EST WED JUL 20 2005 .AVIATION... ONGOING CONVECTION JUST PRIOR TO 23Z WAS JUST EAST OF FWA. OTHER CONVECTIONS WAS FIRING OVER NORTHERN IL AND WAS SLIDING SE. VERY UNSTABLE AIR WAS SOUTH OF THIS CONVECTION...ALTHOUGH THE AIRMASS FARTHER EAST OVER N INDIANA HAS BEEN SIGNIFICANTLY MODIFIED BY EARLIER/ONGOING CONVECTION. GIVEN TRAJECTORY OF STORMS OVER NORTHERN IL AND MORE STABLE AIR TO THE EAST...HAVE KEPT STORMS OUT OF SBN AND FWA TAFS. HOWEVER...DID INDICATE SOME LOWER CIGS AND VSBYS OVERNIGHT AS AIRMASS ALREADY IS NEAR SATURATION. CONDITIONS SHOULD IMPROVE AFTER DAYBREAK WITH DAYTIME HEATING. && .SHORT TERM... TONIGHT AND THURSDAY... MCV MOVG EAST ACROSS WI THIS AFTN AIDING CONVECTIVE DVLPMNT TO OUR NW TODAY. WK SFC BOUNDARY EXTENDING FROM SRN LM SEWD ACROSS NWRN PORTION OF CWA WITH VERY WARM MOIST SW INFLOW ALSO HELPING TO SUSTAIN STORMS. LATEST NAM SEEMS TO HAVE DECENT HANDLE ON CONVECTIVE TRENDS...ALTHOUGH LOOKS A LITTLE SLOW WITH THE DVLPMNT. EXPECT THE MCS WILL CONTINUE TO MOVE SE ACROSS THE CWA THIS EVE AND WILL GO WITH LIKELY/CAT POPS OVER ALL BUT EXTREME SE. MAIN QUESTION IS IF MORE DVLPMNT WILL OCCUR BEHIND THIS LINE. THERE IS SOME CONVERGENCE OVER WRN WI SO FURTHER DVLPMNT POSSIBLE, THOUGH, ATTM APPEARS BEST FORCING WILL BE ASSOCD WITH ONGOING MCS AND WILL JUST GO WITH A CHC OF TSTMS AFTER MIDNIGHT. LIKEWISE, FORCING FOR MORE TSTMS TOMORROW IS QUESTIONABLE, BUT APPEARS THERE WILL BE WK LEFT OVER BOUNDARIES IN THE AREA ALONG WITH MODERATE INSTABILITY SO WILL LEAVE GOING CHC OF TSTMS IN FCST. GOING MINS TONIGHT GNRLY IN L70S SEEM REASONABLE AND NO CHANGES MADE. H85 TEMPS SUGGEST WE COULD WARM INTO THE L-M90S ON THU, BUT WITH LIGHT GRADIENT APPEARS MIXING WILL BE LIMITED AND THUS WENT WITH MET/MAV COMPROMISE WHICH IS IN U80S-L90S. WILL NEED TO WATCH HEAT INDEX FOR PSBL NPW, BUT, ATTM, APPEARS MARGINAL AND IF WE HIT CRITERIA WILL PRBLY BE BRIEF. && .LONG TERM... THURSDAY NIGHT THROUGH WEDNESDAY...RICH THETA E AIR HAD RETURNED ALREADY AHEAD OF NEXT SYSTEM. SHOULD BE PLENTY OF MOISTURE AVAILABLE AS NEXT DISTURBANCE MOVES ACROSS IN HIGH ZONAL FLOW OVER THE AREA...SO EXPECT SOME LINGERING THUNDERSTORMS THURSDAY NIGHT. FOR FRIDAY THROUGH NEXT WEDNESDAY...OVERALL PATTERN IS FOR THE UPPER RIDGE TO BUILD EAST INTO THE MID MISSISSIPPI VALLEY THEN FOR A DEEP UPPER TROF TO BUILD SOUTHEAST INTO THE GREAT LAKES REGION. KEPT TEMPERATURES WELL ABOVE NORMAL AHEAD OF THIS SYSTEM SUNDAY AND MONDAY. ADDED A CHANCE FOR THUNDER TUESDAY AND TUSDAY NIGHT AHEAD OF THIS NEXT SYSTEM. WENT WITH ONLY UPPER 70S FOR HIGHS WEDNESDAY AS GFS IS SHOWING SOME RUN TO RUN CONSISTENCY ALONG WITH THE 12Z ECMWF. MEX AND 850 MB FORECAST TEMPS INDICATE HIGHS IN THE 70S. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE. LM...NONE. && AVIATION/SHORT TERM...JT/SKIP LONG TERM...SKIP
