River Flood Warning 45, NWS Northern Indiana

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTHERN INDIANA
1045 AM EDT SUN MAR 8 2009

.UPDATE...

PREVIOUS FORECAST LOOKING VERY GOOD AND HAVE ONLY MADE SOME MINOR
ADJUSTMENTS THIS MORNING. VERY STRONG SURFACE BOUNDARY NOW LOCATED
JUST SOUTH OF THE CWA WITH TEMPS PRETTY MUCH IN THE 40S CWA-WIDE.
BAND OF HEAVIER RAINFALL ASSOCIATED WITH A BAND OF FN CONVERGENCE
AROUND THE H850 LEVEL IS BEGINNING TO PULL NORTH AND EAST AS FLOW
AT THIS LEVEL SOUTH OF THE 850 FRONT BEGINS TO BACK SOME IN
RESPONSE TO THE INTENSE SHORTWAVE PULLING INTO IOWA/MISSOURI ATTM.

FOLLOWING CLOSER TO THE NAM EVOLUTION IN THE NEAR TERM GIVEN IT/S
SUPERIOR INITIALIZATION AT 12UTC...ALONG WITH THE RUC WHICH IS
QUITE SIMILAR...IT APPEARS THE SURFACE FRONT WILL LIFT NORTH TO A
LINE SOMEWHERE BETWEEN ROUTE 30 AND ROUTE 6...PRETTY MUCH
BISECTING THE CWA. SOUTH OF THIS BOUNDARY...SVR POTENTIAL IS
LOOKING MORE AND MORE LIKELY AS NEGATIVELY TILTED SHORTWAVE
ARRIVES LATER TODAY WITH 90-100KT SPEED MAX AT 500 HPA. SHEAR
LOOKS IMPRESSIVE AT ALL LEVELS AND AS IS TYPICAL THIS TIME OF
YEAR...MAIN QUESTION WILL BE THE INSTABILITY. COLD POOL ALOFT
APPEARS TO ARRIVE IN THE AREA AROUND 21Z...JUST AHEAD OF THE
SURFACE COLD FRONT AND IN THE WARM SECTOR...WITH 300-500 J/KG OF
CAPE POSSIBLY DEVELOPING...PARTICULARLY OVER THE SOUTHERN EDGE OF
THE CWA...ALONG AND SOUTH OF ROUTE 30. THIS WILL BE PLENTY GIVEN
THE STRONG DYNAMICS TO DEVELOP ROBUST CONVECTION WITH DAMAGING
WINDS AND LARGE HAIL BOTH POSSIBLE GIVEN THE IMPRESSIVE WIND
FIELD...AND WELL POSITIONED WET BULB ZERO LINE. SLIGHT RISK FROM
SPC IS IN GOOD AGREEMENT WITH THIS THINKING AND THEREFORE WILL
CONTINUE SVR MENTION IN MY OH/IN ZONES.

ALL THE FLAGS LOOK FINE GIVEN SOME MINOR FLOOD PROBLEMS THIS
MORNING AND SOME ADDITIONAL RAINFALL. ALSO...WIND THREAT LOOKS
INTACT THIS EVENING WITH STRONG COLD ADVECTION IN THE WAKE OF THE
DEPARTING LOW...IN TANDEM WITH AN INTENSE STRATOSPHERIC INTRUSION
OF DRY AIR.

UPDATED GRIDS/PRODUCTS ARE OUT.

.PREV DISCUSSION... /ISSUED 730 AM EDT SUN MAR 8 2009/

AVIATION...
IFR CONDITIONS WITH WIDESPREAD RAIN, LOW CIGS, AND SCT TSTMS CONTG
NORTH OF STNRY FRONT ACROSS NRN IN/IL ATTM. FRONT SHOULD LIFT
NORTH OF THE AREA THIS AFTN ALLOWING FOR BRIEF IMPROVEMENT, BUT
WILL QUICKLY BE FOLLOWED BY COLD FRONT TOWARD EVE. ADDITIONAL
TSTMS ARE PSBL WITH THE FROPA. BEHIND THE FRONT STRONG WLY WINDS
WITH GUSTS AROUND 40KTS ARE EXPECTED MUCH OF THE NIGHT. WRAP
AROUND LOW CLOUDS SHOULD KEEP MVFR CIGS OVER THE AREA THROUGH
MONDAY MORNING.

PREV DISCUSSION... /ISSUED 616 AM EDT SUN MAR 8 2009/

UPDATE...
TEMPS SOUTH OF FRONT OVER CENTRAL IL/IN IN THE L-M60S ATTM. MODELS
ARE A BIT TOO COOL IN THIS AREA. EXPECT THIS WARMER AIR WILL
OVERSPREAD THE AREA THIS AFTN AS THE FRONT LIFTS NE. BUMPED UP
HIGHS ABOUT A CATEGORY ACROSS THE CWA WITH HIGHS RANGING FROM THE
U40S NORTH TO THE MID 60S SOUTH. HIGHS IN THE NE MAY ACTUALLY
OCCUR EARLY THIS EVE AFTER 00Z.

DISCUSSION...
STNRY FRONT FROM OH TO KS THIS MORNING WAS THE FOCUS FOR A LARGE
AREA OF RAIN ALONG AND NORTH OF THE BOUNDARY. BULK OF TSTM ACTIVITY
ATTM REMAINS WEST OF OUR AREA FROM IL-KS CLOSER TO NOSE OF LLJ. AS
STRONG SHRTWV LIFTS NE FROM SRN PLAINS TODAY, ATTENDANT SFC/H85
LOW WILL DEEPEN AND LLJ WILL ALSO PROGRESS NE CAUSING UPSTREAM
SHOWERS AND TSTMS TO MOVE EAST ACROSS OUR CWA. ALREADY OVER AN
INCH OF RAIN HAS FALLEN ACROSS THE CWA AND APPEARS GOOD POTENTIAL
FOR ADDITIONAL HEAVY RAIN TODAY SO CONTD WITH FLOOD WATCH THROUGH
THIS EVE. WARM FRONT ASSOCIATED WITH THIS SYSTEM WILL MOVE ACROSS
THE AREA THIS AFTN. SHOULD BE A BRIEF BREAK IN PRECIP AS THIS
OCCURS. WK SFC BASED INSTABILITY IN THE WARM SECTOR COMBINED WITH
HIGH SHEAR ENVIRONMENT SUGGESTS POTENTIAL FOR SVR TSTMS
ALONG/AHEAD OF CDFNT MOVG THROUGH THE AREA LATE THIS AFTN/THIS
EVE WITH BEST CHC IN SOUTH WHERE INSTABILITY WILL BE GREATEST. BEHIND THE
FRONT A STRONG PRESSURE/ISALLOBARIC GRADIENT WILL MOVE ACROSS THE
CWA TONIGHT. STEEPENING LOW LEVEL LAPSE RATES DUE TO CAA SHOULD
ALLOW STRONG WINDS TO MIX DOWN TO SFC FOR A 3-6HR PD WITH GUSTS
AROUND 40KT EXPECTED, THUS, ISSUED A WIND ADVISORY FOR TONIGHT.
HIGH PRESSURE WILL BUILD INTO THE AREA MONDAY PROVIDING FAIR WX.
RIDGING ALOFT WILL OVERSPREAD THE AREA DURING THE DAY MONDAY AS
ANOTHER SHRTWV DIGS INTO MEAN WRN TROF. WITH CONSIDERABLE SUNSHINE
EXPECTED, THIS SHOULD ALLOW HIGHS TO AGAIN RECOVER TO ABOVE NORMAL
READINGS IN THE U40S-L50S OVER MOST OF THE AREA...A LITTLE COLDER
NEAR LM WHERE LAKE BREEZE WILL PERSIST THROUGH THE DAY AS GRADIENT
DIMINISHES. FRONTAL BOUNDARY IS EXPECTED TO SURGE BACK NORTH INTO
THE LWR OH VALLEY MONDAY NIGHT AS ANOTHER STRONG SHRTWV DIGS INTO
THE CENTRAL ROCKIES CAUSING SFC LOW TO DVLP OVER CO/KS. MODELS IN
GOOD AGREEMENT ON OVER-RUNNING SHOWERS SPREADING INTO THE AREA
AHEAD OF THE FRONT MONDAY NIGHT AND TUESDAY MORNING SO BUMPED UP
POPS INCREASED POPS 20-30% DURING THIS PERIOD. DEEP LOW PRESSURE
ASSOCIATED WITH THIS SHRTWV EXPECTED TO LIFT NE TO THE UPR GRTLKS
TUE NGT WITH STRONG CDFNT PUSHING EAST ACROSS OUR AREA. AGAIN SOME
WK INSTABILITY SHOULD OVERSPREAD THE AREA IN THE WARM SECTOR, HWVR
QUESTIONABLE HOW MUCH MOISTURE WILL REMAIN AS THE CDFNT MOVES
THROUGH, SO LEFT POPS FOR TUE NGT IN THE CHC CATEGORY. NO SGFNT
CHANGES MADE TO DAYS 4-7, WHICH STILL APPEARS TO BE A COOL/DRY PD
AS CANADIAN SFC HIGH MOVES SLOWLY ACROSS THE GRTLKS.
