NWS Northern Indiana wrote its last area forecast discussion before the first event at Sep 3, 5:30 AM EST, 3 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 530 AM EST FRI SEP 3 2004 .AVIATION... SCATTERED SHOWERS CONTINUE TO DEVELOP AND WORK NORTH FROM CENTRAL INDIANA EARLY THIS AM. EXPECT THIS TREND TO CONTINUE WITH COVERAGE EXPECTED TO INCREASE SOMEWHAT. WILL GO PREDOMINATE VFR CIGS/VSBY FOR MOST OF THE DAY WITH A TEMPO IN FOR LATER THIS AM WHEN INSTABILITY INCREASES AND MAIN ENERGY MOVES OVERHEAD WITH BEST CHANCE. CHC OF THUNDER ALSO EXISTS BUT DOESNT LOOK WIDESPREAD ENOUGH AT THIS TIME TO WARRANT MORE THAN A CB MENTION ON THE CIGS. AREAS OF FOG THIS MORNING SHOULD BURN OFF AS WAVE MOVES CLOSER. PRECIP SHOULD END FROM SOUTH TO NORTH LATER THIS AFTERNOON...WITH CIGS IMPROVING INTO THE OVERNIGHT HOURS. COULD BE SOME PATCHY FOG ONCE AGAIN TOWARDS SAT AM SO HAVE OPTED FOR TEMPO GROUP IN MVFR FOG FOR NOW. && .DISCUSSION... SHORT TERM... TODAY AND TONIGHT. UPPER LEVEL DISTURBANCE CURRENTLY LOCATED WEST OF KHUF HAS BEEN WELL HANDLED BY 18Z AND 00Z MESOETA MODEL. THIS FEATURE IS PROGGED TO MOVE NORTH AND EAST THROUGH THE DAY. SCATTERED SHOWERS AND STORMS CONTINUE ACROSS PORTIONS OF CENTRAL INDIANA...WITH SOME OF THE SHOWERS TRYING TO WORK INTO THE SOUTHERN PARTS OF THE FORECAST AREA AS OF 6Z. UPPER LEVEL DIVERGENCE INCREASES THIS AM AND PEAKS OUT AROUND 18Z...AS DOES BEST LIFT. THEREFORE WITH SOME HEATING IN THE AM...INCREASING INSTABILITY AND APPROACH OF THE WAVE...THINK SCT SHOWERS AND THUNDERSTORMS WILL OCCUR OVER MUCH OF THE AREA...WITH BEST CHC SOUTH THIS AM AND SHIFTING NORTH FOR THE AFTN. WILL BUMP POPS UP TO HIGH CHC IN NORTHERN COUNTIES WHERE BEST LIFT/DIVERGENCE IS SET TO BE AROUND 18Z...THEN A DOWNWARD TREND EXPECTED BY LATE AFTERNOON/EARLY EVE AS MAJORITY OF THE ENERGY SHIFTS NE OF THE AREA AFTER 21Z. AS FOR HIGH TEMPS TODAY...WILL BE SOME MID AND HIGH CLOUDS AROUND TO START THE DAY...WITH LOWER CLOUDS MAINLY ASSOCIATED WITH ANY PRECIP. THIS BEING SAID...STILL THINK TEMPS SHOULD MANAGE TO RISE TO AROUND OR JUST INTO THE LOWER 80S...SO NO CHANGES TO TEMPS TODAY. TONIGHT...MAIN LIFT WITH WAVE WILL SHIFT INTO MICHIGAN AND OHIO...WITH ANY PRECIP QUICKLY ENDING BY LATE AFTERNOON/EARLY EVE. WILL HOLD ONTO DRY FORECAST OVERNIGHT. DEPENDING ON AMOUNT OF RAINFALL ACROSS THE AREA...COULD BE SOME FOG ONCE AGAIN TONIGHT. FOR NOW WILL HOLD OFF ON MENTION IN ZONES AND LET DAY SHIFT EVALUATE THE POTENTIAL. LOWS WILL FALL INTO THE LOW 60S ONCE AGAIN WITH SLIGHTLY COOLER TEMPS NEAR THE LAKE. LONG TERM... SATURDAY THROUGH THURSDAY. AGAIN EXTRATROPICAL MORPHING OF LANDFALLING FRANCES DOMINATES THE LONG TERM. MANY QUESTIONS REMAIN INCLUDING IF REMAINS OF FRANCES GET INCORPORATED INTO WRN TROF AND ASSOCD FRONTAL ZONE...TIMING OF WRN TROF EJECTION INTO THE CNTRL US...AND WHERE EXACTLY FRANCES ENDS UP INLAND. GFS ALL OVR THE PLACE LATELY FROM RUN TO RUN BUT SIMILAR NOW IN SCOPE W/ECMWF AND UKMET WHICH SHOW REMAINS OF FRANCES STAYING SOUTH OF MAIN WESTERLIES WHICH SHIFT INTO CANADA TWD MID WEEK. AS A RESULT...GIVEN RIDGE ALOFT OVR SOUTHWEST US...REMAINS OF FRANCES PROGGED TO COME TO A HALT OVR SRN MS RIVER VALLEY AND STAY PUT GIVEN ABSENCE OF UPSTREAM KICKER. HWVR IN THE LEAST RESULTANT LG SCALE DOMINATION OF THAT CIRCULATION TO HAVE AN EFFECT HERE. BOTTOM LINE IS TO KEEP GOING POPS THROUGH WED NIGHT IF NOT INDEED LONGER AS WE GET CLOSER. UNTIL THEN...NO SUPPORT SUN FOR PRIOR POP MENTION AND DROPPED THIS AM. SAT LTL BETTER GIVEN RIDGING ALOFT AHD OF DIGGING WRN TROF AND OVERALL DRYING OUT BUT PERHAPS ENOUGH DESTABILIZATION IN THE AFTN IN TANDEM W/DEPARTING VESTIGE OF SRN STREAM SYS TO WARRANT GOING 30. OTHERWISE...MAIN SHOW RELEGATED WITH INCOMING WRN SYS WHICH AS SUSPECTED YDA HAS SLOWED DOWN CONSIDERABLY GIVEN INFLUX OF UPSTREAM JET ENERGY DIVING SE OUT OF GULF OF AK. GOING 40S SEEM VERY REASONABLE THEN W/SOME PENCHANT FOR SVR MONDAY AFTN. FOCUS THEN TURNS TO FRANCES. && .AVIATION... SMALL AREA OF SHOWERS/STORMS NEAR KLAF WILL NOT AFFECT TAF SITES OVERNIGHT. HOWEVER...WILL NEED TO WATCH FOR ADDITIONAL DEVELOPMENT ACROSS CNTRL INDIANA THAT MODELS INDICATE COULD WORK IN LATER TONIGHT AND ON FRIDAY. FOR NOW...NO PRECIP ADDED FOR THE OVERNIGHT HOURS AND KEPT TEMPO GROUP INTACT AT BOTH SITES LATE AM INTO EARLY PM. COULD BE SOME PATCHY FOG AROUND AS WELL TOWARDS SUNRISE...SO HAVE KEPT TEMPO MVFR VSBYS GOING AS WELL. CIGS WILL REMAIN VFR THROUGH MUCH OF THE PERIOD...WITH LOCAL MVFR CIGS POSSIBLE IN SHOWERS/STORMS. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE OH...NONE. && SHORT TERM/AVIATION...LF LONG TERM...TH
