AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
750 PM EDT FRI SEP 7 2007

.AVIATION...
WV IMAGERY SHOWING MUCH DRIER MID LEVEL AIRMASS DIVING SEWD FROM
KFNT-KASW-KLAF AT 23 UTC IN PRIMARILY SUBSIDENT REGIME IN WAKE OF
PRIMARY MIDTROPOSPHERIC WAVE PUSHING INTO SERN ONTARIO WELL AHEAD OF
SFC FRONTAL BOUNDARY PUSHING THROUGH CHICAGOLAND. DISJOINTED SFC AND
UL FEATURES ALONG WITH MEAGER SFC BASED INSTABILITY OWING LARGELY TO
EXTREMELY POOR MID LEVEL LAPSE RATES BLO 5.5 C/KM. BOTTOM LINE
PRIMARILY VFR WITH OCNL SHRA NEXT FEW HOURS BEFORE FRONTAL PASSAGE.
SHALLOW FOG THEN TO BECOME FORECAST ISSUE WITH RATHER HIGH XOVER
TEMPS OF 67 AT KSBN AND 69 AT KFWA ALONG WITH RECENTLY MOISTENED
GROUND/NEAR SURFACE. WHILE IFR/LIFR WITHIN REALM OF POSSIBILTY AT
BOTH SITES...WILL SIDE WITH GREATER LIKELIHOOD OF LOW LEVEL DRY AIR
REACHING INTO KSBN BY DAYBREAK WITH MVFR CONDITIONS AND TEMPO IFR AT
KFWA WITH SFC FRONTAL WAVES TO SLOW SEWD PROGRESSION OF LOWER SFC
DEWPOINTS INTO KFWA.

&&

.SHORT TERM...TONIGHT AND TOMORROW.
SOME RAIN SHOWERS MOVED THROUGH THIS MORNING...THEN A SHORTWAVE
MOVED THROUGH THE MIDDLE PART OF THE DAY AND IS JUST NOW(19Z)
LEAVING THE EASTERN PART OF OUR CWA. WHEN THIS WAVE MOVED INTO THE
WESTERN PART OF THE CWA SOME SHOWERS POPPED UP BUT NOTHING
WIDESPREAD...AND THERE WAS NO LIGHTENING DETECTED. ANOTHER SHORTWAVE
IS IN NORTHWESTERN INDIANA AND WILL BE MOVING EASTWARD THROUGH THE
CWA. SOME SHOWERS/STORMS HAVE POPPED UP WITH THIS ONE...BUT NOTHING
WIDESPREAD IS EXPECTED. ALTHOUGH SEVERE WEATHER IS ALSO NOT
EXPECTED...UPPER 60S TO 70 DEWPOINTS HAVE CREPT IN AND IF ENOUGH
HEATING CAN OCCUR IN A SPOT...THEN IT IS POSSIBLE FOR A STORM TO
BECOME SEVERE...AND WITH THE STRONG WINDS ALOFT...DAMAGING WINDS
WILL BE THE MAIN CONCERN. THE EXTENSIVE CLOUD COVER TODAY HAS HELPED
TO LIMIT THE SEVERE STORM POTENTIAL...AND COULD ALSO HELP LIMIT THE
SEVERE POTENTIAL INTO THE EVENING HOURS. THE IWX VAD WIND PROFILE
HAS BEEN SHOWING 40 TO 50 KNOTS AT 2000-3000FT. SURFACE WINDS TODAY
HAVE STAYED AT ABOUT 15 TO 25 KNOTS SUSTAINED WITH GUSTS UP TO THE
UPPER 20 KNOTS.

BESIDES THIS SHORTWAVE IN WESTERN INDIANA...THE ONLY OTHER EXPECTED
SHOT OF RAIN IS WITH THE COLD FRONT. THE FRONT IS CURRENTLY LOCATED
FROM WISCONSIN THROUGH NORTHWESTERN ILLINOIS AND EASTERN IOWA.
EARLIER TODAY THE NAM WAS DOING WELL WITH THE TWO WAVES OF RAIN IN
THE AREA AND HAVE MAINLY GONE WITH IT FOR THE TIMING OF THE FRONT
THROUGH THE CWA. BOTH THE NAM AND GFS HAVE BEEN DEVELOPING RAIN
ALONG THE FRONT AS IT MOVES THROUGH...AND SO HAVE PUT IN LIKELY POPS
WITH THE FRONTS PASSAGE. THE WIND WILL BECOME LESS GUSTY AND
DECREASE IN SPEED THIS EVENING AS THE LOW LEVEL JET LOSES ITS
STRENGTH. THIS WILL ALSO DECREASE THE DAMAGING WIND POTENTIAL
THROUGH THE EVENING HOURS. THE COLD FRONT IS THEN PROGGED TO MOVE
THROUGH SBN THIS EVENING AND THROUGH FWA BY AROUND MIDNIGHT. THE
FRONT WILL THEN STALL OUT JUST TO THE EAST/SOUTHEAST/SOUTH OF THE
CWA TOMORROW...AND WITH POSSIBLE WAVES MOVING NORTHEASTWARD ALONG
THE FRONT...SHOWERS/THUNDERSTORMS WILL CONTINUE TO BE A POSSIBILITY
IN THE SOUTHERN HALF OF THE CWA TOMORROW.

&&

.LONG TERM...TOMORROW NIGHT THROUGH FRIDAY.
STILL QUITE A FEW RUN TO RUN
DIFFERENCES IN THE MODELS BUT ENOUGH EVIDENCE THAT FRONTAL ZONE MAY
LINGER OVER THE AREA TO KEEP CHANCE OF SHOWERS AND TSTMS FOR MOST OF
THE WEEKEND, TRY TO DRY OUT MONDAY AND THEN RETURN PCPN MONDAY NIGHT
AND DRY AGAIN ON TUESDAY. FRONTAL INTERACTION WITH NORTHWARD MOVING
LOW FROM GULF COULD PRODUCE ANOTHER RETURN OF PRECIPITATION
WEDNESDAY DEPENDING ON HOW THINGS COME TOGETHER, BUT ENOUGH OF A
THREAT TO MENTION. DRIER AND COOLER AIR SHOULD FINALLY PUSH IN FOR
THURSDAY AND FRIDAY.

HIGH TEMPS MAY FLIRT WITH 80 OVER THE WEEKEND OTHERWISE LOOK FOR
HIGH TEMPS IN THE 70S THROUGH WEDNESDAY...AND POSSIBLY SOME UPPER
60S BY THE END OF THE WEEK. LOWS IN THE LOWER 60S OVER THE WEEKEND,
SLIPPING INTO THE 50S BY TUESDAY AND EVEN SOME 40S BY THE END OF THE
WEEK.
