The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 21, 2:10 PM EST, 4 hours 48 minutes earlier.
Area forecast discussion, Jul 21, 2:10 PM EST, 4 hours 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 210 PM EST WED JUL 21 2004 .SHORT TERM... TONIGHT AND THURSDAY. MAIN CHALLENGE LIES WITH CONVECTION CHANCES TONIGHT. INITIAL BOUNDARY FROM OVERNIGHT CONVECTION IS MOVING ACROSS THE FORECAST AREA WITH LITTLE MORE THAN A FEW SHOWERS ACROSS MICHIGAN. PLENTY OF INSTABILITY IN PLACE JUST TO THE WEST WITH LIS -9 TO -11 AND CAPES 3K TO 4K J/KG. VIS SAT SHOWS ANOTHER OUTFLOW BOUNDARY FROM EASTERN WISCONSIN TO CENTRAL ILLINOIS...JUST TO THE WEST OF THE INSTABILITY AXIS. THIS MAY END UP BEING THE FOCUS FOR THE EXPECTED LINE OF THUNDERSTORMS TONIGHT. MAIN LIMITING FACTOR HAS BEEN STRONG CAP ACROSS MUCH OF THE AREA (SEE 18Z KILX AND KDVN SOUNDINGS). MODELS SHOW THIS CAP BEING ELIMINATED AS SLIGHTLY COOLER 850 MB TEMPS AND APPROACHING SHORTWAVE/MCV MOVE IN. AREA UNDER A MDT RISK FOR THIS AFTERNOON AND EVENING WITH WIND PROFILES TO THE WEST STARTING TO LOOK MORE FAVORABLE FOR DAMAGING WINDS. EXPECTING NEW WATCH FOR THE AREA OVER THE NEXT COUPLE OF HOURS. HAVE ADJUSTED TIMING OF PRECIP SOMEWHAT WITH LIKELY POPS WEST TO START SPREADING ACROSS THE AREA BY MIDNIGHT THEN BACK TO CHC POPS BEHIND THE MAIN LINE FOR ANYTHING LINGERING. WITH PWATS NEAR 2 TO THE WEST EXPECTED TO MOVE IN...HEAVY RAINFALL ALSO A GOOD BET. LOWS WILL FALL BACK INTO THE LOWER 70S AS DRIER AIR DOESNT START MOVING IN TILL EARLY THURSDAY. MUCH OF THURSDAY COULD BE DRY IN SUBSIDENCE BEHIND TONIGHTS SYSTEM. MODELS HINT AT NEXT WAVE TO MOVE IN TOWARDS EVE FOR ANOTHER CHANCE OF PRECIP. WILL GO WITH 30 POPS ALL AREAS FOR THURS FOR NOW AND LET OVERNIGHT CREW MAKE CHANGES BASED ON FRONTAL POSITION. WITH 850 MB TEMPS STILL EXPECTED +19 TO +20...HIGHS SHOULD MAKE IT INTO THE UPR 80S. && .LONG TERM... SOME CHANGES TO EXTENDED BASED ON LATEST MODEL RUNS. TEMPERATURES LOOK GOOD AND FEW CHANGES MADE THERE. FORECAST CHALLENGE IS WITH POPS FRIDAY THEN AGAIN MONDAY NIGHT THROUGH TUESDAY NIGHT. FRONT TO PUSH THROUGH THURSDAY BUT MODELS HINTING AS AN MCS DEVELOPING ON NORTH SIDE OF FRONT THURSDAY NIGHT AND MOVING ALONG FRONT FRIDAY. LATEST ETA40 SHOWS ALL ACTIVITY SOUTH OF OUR AREA BY 12Z FRIDAY WITH DRY NORTHEAST FLOW BEHIND. LEANING TOWARD THIS SOLUTION AS IT MATCHES CURRENT GRIDS AND SEEMS PLAUSIBLE AT THIS POINT. THUS NO ADDITIONAL POPS FOR FRI. GFS AND ECMWF AS WELL AS UKMO AGREE ON INVERTED TROUGH OVER OUR AREA MONDAY NIGHT INTO TUESDAY NIGHT WITH A COUPLE OF POSSIBLE WAVES RIDING NORTH ALONG FRONT. SURFACE TROUGH IS NEAR OUR EASTERN AREAS BUT UPPER TROUGH STILL TO OUR WEST AND SLIGHTLY DIGGING. THUS SURFACE TROUGH COULD END UP FARTHER WEST AND ANY PCPN MOVING NORTH OUT OF OPEN GULF AND ATLANTIC COULD BE DRAWN FARTHER WEST. THUS WILL NOT TRY AND DIFFERENTIATE ACROSS THE AREA AND ADD POPS TO ENTIRE FORECAST AREA AT THIS TIME WITH PRETTY GOOD MEDIUM RANGE MODEL AGREEMENT. && .AVIATION... TOUGH FORECAST FOR THE NEXT 6 TO 12 HOURS AS INITIAL LINE OF CONVECTION HAS WEAKENED...BUT OUTFLOW BOUNDARY FROM IT IS NOW INTERACTING WITH VERY UNSTABLE ATMOSPHERE NEAR KSBN. STILL A CHANCE THAT SOMETHING COULD FIRE ALONG THIS AND HEAD EAST. CONFIDENCE LOW AT THIS TIME SO NO MENTION OF PRECIP THIS AFTERNOON. ANOTHER SHOT AT PRECIP LOOKS TO MOVE IN THIS EVENING WITH MCV IN MN/IA AT THIS TIME. LOTS OF UNCERTANTITY WITH THIS AS WELL DEPENDING ON ANY AFTERNOON CONVECTION ACROSS THE AREA. AT THIS TIME...HAVE OPTED TO GO WITH MENTION OF VCTS FOR SEVERAL HOURS AS BETTER DYNAMICS MOVE IN. LATER FORECASTS CAN HOPEFULLY FINE TUNE THINGS BETTER. WILL KEEP VFR SKIES/VSBYS BUT LOCAL MVFR/IFR WILL BE POSSIBLE WITH ANY CONVECTION THAT CAN FORM. STRONG WINDS EXCEEDING 50 KTS WILL ALSO BE POSSIBLE...BUT AGAIN CONFIDENCE TOO LOW TO PLACE IN TAFS. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE. && FISHER/LASHLEY
