AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
457 PM EDT MON MAY 3 2010

.UPDATE...

QUICK UPDATE TO REFINE POPS BASED ON AFTERNOON RADAR EVOLUTION.
UPPED POPS TO CAT OVER SOUTHWESTERN AREAS GIVEN EXPANSION OF
STRATIFORM REGION INTO THIS AREA. OTHERWISE...GOING FORECAST ON
TRACK.

&&

.PREV DISCUSSION... /ISSUED 219 PM EDT MON MAY 3 2010/

NEAR TERM...

THIS AFTERNOON/EARLY EVENING

MID LEVEL IMPULSE NOW ENTERING WESTERN IL WILL CONTINUE
TO SUPPORT DESTABILIZATION AS MID LEVEL TEMPS SLOWLY COOL AND LL
REFLECTED SOUTHERLY FLOW SUPPORTS WEAK LL THETA-E RIDGING PER
MOISTURE TRANSPORT. OUTFLOW MODIFIED SFC BOUNDARY IN PLACE OVER
CENTRAL IL WITH DECENT LL CONVERGENCE NOTED...IS SUPPORTING AN
AGGRAVATED CU FIELD WITH TCU NOTED NEAR KAAA. DEBRIS ASSOCIATED
WITH THE DYNAMICALLY FORCED CONVECTION FROM THIS MORNING IS
BASICALLY THE LEADING EDGE MARKER FOR INCREASED LARGE SCALE ASCENT
AND ASSOCIATED MID LEVEL COOLING AND IS EXPECTED TO SUPPORT
CONVECTIVE GROWTH THIS AFTERNOON AS THE BL FURTHER
DESTABILIZES...WITH SB CAPES AOA 1000 J/KG. ILX 12Z RAOB CERTAINLY
SUPPORTS A STRONG GUSTY WIND THREAT GIVEN VERY STEEP LL AND MID
LEVEL LAPSE RATES...WITH 7 C/KG H85-H5. SUFFICIENT DEEP CLOUD
BEARING SHEAR OF 40 TO 50 KNOTS WILL SUPPORT STORM SCALE
ORGANIZATION WITH BOWING SEGMENTS POSSIBLE WHERE THE STRONGEST LOCAL
FORCING IS REALIZED...ESPECIALLY STORMS THAT ORGANIZE PERPENDICULAR
TO THE LL SHEAR VECTOR. IN ADDITION...LOCALIZED HAIL WILL BE
POSSIBLE GIVEN SUFFICIENT CAPE IN THE HAIL GROWTH ZONE. CURRENT
FORECAST TIMING BRINGS ACTIVITY INTO THE WESTERN FA BY 21-22Z.

SHORT TERM...

TONIGHT THROUGH TUESDAY

WEAK MID LEVEL IMPULSE AHEAD OF AN ADVECTING CENTRAL/NORTHERN PLAINS
SHORTWAVE TROUGH...WILL CONTINUE TO PUSH EAST THROUGH
TONIGHT...SUPPORTING A SFC TROUGH INTO THE REGION OVERNIGHT. SHRA/TS
ARE EXPECTED TO BE ONGOING BY THE START OF THE PERIOD. MID-LEVEL
TROUGHING IS EXPECTED TO BE REPLACED BY SHORTWAVE RIDGING BY MID
AFTERNOON TUES AS FLOW QUICKLY RESPONDS TO HEIGHT FALLS OVER THE
NORTHERN PLAINS PER A POTENT TROUGH EXITING THE PAC NW. BACKING LL
FLOW WILL QUICKLY SUPPORT WAA INTO THE REGION WITH ANOTHER MILD DAY
IN STORE ONCE AGAIN...ESPECIALLY WITH A PUSH OF MUCH DRIER LL AIR
WORKING INTO THE REGION. THIS DRIER AIR WILL ALLOW A QUICK DIURNAL
REPONSE TO INSOLATION ESPECIALLY GIVEN AN OVERALL LACK OF SKY COVER
ANTICIPATED.

TONIGHT...SHRA/TS ACTIVITY OF A SCT NATURE IS EXPECTED TO CONTINUE TO
PUSH EAST WITH A SFC TROUGH OFFERING MUCH DRIER AIR INTO THE REGION
NW-SE. GIVEN PARAMETERS MENTION IN THE NEAR TERM SECTION ABOVE...THE
POTENTIAL FOR GUSTY WINDS AND HAIL WILL BE ONGOING...INTO THE
EVENING WITH A TREND TO JUST GUSTY/STRONG WINDS AS INSTABILITY
WANES. HAVE CONTINUED A MENTION OF GUSTY WINDS AND SMALL HAIL FOR
EASTERN AREAS IN THE GRIDS. THINGS ARE EXPECTED CLEAR OUT RATHER
FAST POST FRONTAL...WITH MOSTLY CLEAR SKIES EXPECTED BY DAWN.

TUES...SHORTWAVE RIDGING AND ASSOCIATED WAA PER BACKING LL FLOW WILL
SUPPORT MOSTLY SUNNY SKIES. PRESSURE FALLS OVER THE UPPER MIDWEST
WILL SUPPORT A RESPONSE TO THE LOCAL FIELD HERE...WITH BREEZY
CONDITIONS EXPECTED BY AFTERNOON...ESPECIALLY GIVEN DEEP AFTERNOON
MIXING. MIXING HEIGHTS AOA H85 WILL SUPPORT MAX T/S INTO THE LOW TO
MID 70S AT MOST PLACES...WARMEST IN THE SW ZONES.

TUES NIGHT...NORTHERN PLAINS VORTEX WILL CONTINUE TO PUSH EAST WITH AN
INTACT SFC REFLECTION PUSHING EAST TOWARD THE REGION. BEST SUPPORT
FOR LARGE SCALE ASCENT AND LIFT IS EXPECTED TO BE PLACED WELL NORTH
OF THE REGION WITH LIMITED MOISTURE RIGHT ALONG AND JUST AHEAD OF THE
ADVANCING FRONTAL BOUNDARY. GIVEN INSTABILITY LULL AND LACK OF
APPRECIABLE FORCING....EXPECTATIONS FOR LINGERING CONVECTION
MAKING IT INTO THE FA IS VERY LOW ATTM AND HAVE CONTINUED WITH A DRY
FORECAST LATE TUES NIGHT. RETAINED CLOUD COVER INCREASE AFTER MIDNIGHT
NW. OTHERWISE...LOOK FOR WARMER TEMPS...ESPECIALLY NW GIVEN INCREASED
LL FLOW...WITH LOWS GENERALLY IN THE 50S.

LONG TERM /WEDNESDAY THROUGH MONDAY/...

..UNSETTLED WEATHER FOLLOWED BY A TRANSITION TO COOLER
TEMPERATURES...

BY THE START OF THIS PERIOD WEDNESDAY...THE FLOW ACROSS THE CONUS
WILL BE RELATIVELY ZONAL...BUT THIS WILL BE SHORT-LIVED AS
DEVELOPING BLOCKING DOWNSTREAM OVER GREENLAND...AS WELL AS UPSTREAM
FLOW AMPLIFICATION OVER THE CENTRAL PACIFIC WILL CAUSE THE FLOW
THROUGHOUT THE CONUS TO BUCKLE...WITH A TROUGH-RIDGE-TROUGH LOOK TO
THE PATTERN ACROSS THE CONUS BY THE END OF THE PERIOD EARLY NEXT
WEEK.  WHILE THE TRANSITION BETWEEN PATTERNS WILL FEATURE UNSETTLED
WEATHER...THE RESULTING WEEKEND PATTERN SUGGEST A DRY PERIOD FROM
SATURDAY-MONDAY WITH TEMPERATURES BELOW SEASONAL NORMS.

OVER THE PAST 24 HOURS...BOTH DETERMINISTIC AND ENSEMBLE GUIDANCE
HAS COME INTO BETTER AGREEMENT WITH THE GFS/GEFS NOW JUMPING ON THE
BANDWAGON WITH A SIGNIFICANT CYCLONE DEVELOPING LATE THIS
WEEK...REACHING OUR AREA THURSDAY NIGHT/FRIDAY. MANY
DETAILS...HOWEVER...REMAIN UNCERTAIN THIS AFTERNOON.

FOR WEDNESDAY...GUIDANCE HAS SHIFTED FASTER WITH THE TIMING OF THE
COLD FRONT /WITH POSSIBLE ARRIVAL DURING THE MORNING OVER NORTHWET
AREAS/ AND HAVE NO REASON TO DOUBT A FASTER TIMING GIVEN STRONG
ZONAL FLOW ACROSS THE CONUS.  THIS WILL PLAY A BIG ROLE IN TEMPS
WITH A LARGE GRADIENT LIKELY ACROSS THE CWA ESPECIALLY IF FLOW TURNS
TO AN ONSHORE DIRECTION DURING THE MORNING.  TRENDED TEMPS NEAR BEH
DOWNWARD TOWARDS 70 AND THIS COULD END UP BEING WELL TOO WARM IF
THIS FASTER TREND CONTINUES.  WITH T85 NEAR 13C OVER THE
SOUTH...HIGHS SHOULD REACH NEAR 80 GIVEN GOOD SOUTHWEST
FLOW/INSOLATION AND THEREFORE DEEP MIXING.  WAS TEMPTED TO BACK
PRECIP TIMING UP A LITTLE GIVEN THE TREND...BUT WITH LIMITED
MOISTURE...STILL BELIEVE AFTERNOON/EVENING GIVES THE BEST CHANCES TO
REALIZE ENOUGH INSTABILITY.  HAVE REMOVED POPS OVER NORTHWESTERN
AREAS AFTER 00Z GIVEN THE QUICKER TIMING BUT OTHERWISE WILL KEEP
POPS IN LOW CHC CATEGORY.

COLD FRONT SHOULD SINK SOUTH OF THE REGION WEDNESDAY NIGHT AND HAVE
LOWERED LOWS SOMEWHAT TO ACCOUNT FOR THIS...WITH LOWS NOW DOWN ABOUT
ONE CATEGORY TO AROUND 50F.

THE NEXT IMPORTANT FEATURE OF NOTE WILL BE A POTENT SHORTWAVE THAT
WILL CROSS THE ROCKIES THURSDAY...AND THEN DEEPEN/SHARPEN SOME AS IT
MOVES INTO THE GREAT LAKES REGION.  INITIALLY...HEIGHT FALLS
DOWNSTREAM OF THIS FEATURE WILL HELP INDUCE BACKED LLEVEL FLOW OVER
THE FRONT IN OUR VICINITY WITH THE IMPLIED LIFT LIKELY BRINGING A
RENEWED CHANCE OF SHRAS/TSRAS.  WHILE MOST RECENT GUIDANCE SUGGESTS
THAT THIS MAY HOLD OFF UNTIL THURSDAY NIGHT...HAVE OPTED TO LEAVE
CHC SHRA/TSRA MENTION THURSDAY AFTERNOON GIVEN A CONTINUED FAST
ZONAL FLOW ALOFT SUGGESTING THE POSSIBILITY THAT THE WAVE MAY MOVE
EAST A LITTLE MORE QUICKLY THAN THESE RECENT RUNS.

A LEE-SIDE LOW WILL FORM LATE THURSDAY AND THEN TRAVEL NORTHEAST TO
A POSITION IN OUR GENERAL VICINITY BY FRIDAY AFTERNOON.  THE ECMWF
CONTINUES TO BE THE NORTHERNMOST SOLUTION WITH A LOW NEAR BEH BY 00Z
SAT WITH THE GFS TAKING THE LOW FROM NEAR IND AROUND 18Z FRI TO NEAR
PIT BY 00Z SAT.  QUITE A FEW GEFS MEMBERS FAVOR THE NORTHERN
SOLUTION...AS DOES THE GGEM.  I WOULD TEND TO LEAN TOWARDS THE MORE
ROBUST/NORTHERN SOLUTION GIVEN THAT THE UPPER FORCING WILL HAVE A
PRETTY STRONG LLEVEL BAROCLINIC ZONE TO WORK WITH...BUT CONFIDENCE IS
NOT GREAT.  WILL KEEP TEMPS A LITTLE ABOVE CLIMO IN THE SOUTH...BUT
CLOSE TO IT IN THE NORTH.  CERTAINLY A SVR THREAT WITH A ECMWF-LIKE
SOLUTION...SO HAVE NO PROBLEM WITH TSRA MENTION AND INCLUSION IN THE
HWO...BUT A MORE GFS-LIKE SOLUTION MAY FAVOR MORE OF A HEAVY RAIN
THREAT WITH MUCH COOLER TEMPERATURES THAN CURRENT GRIDS INDICATE.

LOW WILL MOVE EAST OF THE AREA FRIDAY NIGHT WITH DRIER/MUCH COOLER
AIR MOVING IN AS WE SEE A POLAR AIRMASS MOVE INTO THE REGION.  BY
SATURDAY...T85S DROP BELOW 0C TO AROUND -3C SUGGESTING THAT HIGHS MAY
STRUGGLE TO REACH MUCH HIGHER THAN THE LOWER 50S.  LOWERED GOING
TEMPS WITH THIS PACKAGE...BUT NOT QUITE TO THIS EXTENT TO AVOID
LATER FLIP-FLOPPING.  EXPECT SELF-DESTRUCTIVE SUNSHINE SATURDAY TO
FEATURE A MIX OF SUN AND CLOUDS WITH MORE CLOUDS IN THE AFTERNOON.

AMPLE SUNSHINE...MODERATING TEMPS...AND DRY CONDITIONS ARE EXPECTED
SUNDAY-MONDAY UNDER NORTHWEST FLOW ALOFT.  DEFINITELY NOT READY TO
BUY THE 12Z GFS WHICH ALREADY BRINGS WARM ADVECTIVE PRECIP IN HERE
MONDAY.  THIS EVOLUTION SEEMS FAR TOO FAST GIVEN THE DOWNSTREAM
BLOCKING AND IT/S IMPLIED SLOWER MOTION FOR THE DEPARTING CLOSED LOW
OVER NEW ENGLAND.  EXPECT HIGHS TO REBOUND TO THE UPPER 50S TO
AROUND 60 ON SUNDAY AND THEN BACK INTO THE 60S...BUT STILL BELOW
SEASONAL NORMS ON MONDAY.  GIVEN THE DRY SOURCE REGION OF THE
AIRMASS...AS LONG AS ENOUGH CLEARING OCCURS BOTH SATURDAY AND SUNDAY
NIGHTS...FROST LOOKS LIKE A DEFINITE POSSIBILITY.  WILL NOT ADD TO
GRIDS GIVEN THE TIME RANGE...BUT MAKE MENTION IN THE AFTERNOON HWO.

AVIATION.../18Z TAFS/
MID LEVEL IMPULSE WILL CONTINUE TO SHIFT NE ACROSS THE FA
TODAY/TONIGHT...SUPPORTING SCT SHRA/TS THIS EVENING. ACTIVITY IS
EXPECTED TO IMPACT THE REGION WITH CIG/VIS RESTRICTIONS IN THE
HEAVIEST ACTIVITY. IN ADDITION...ISOLATED GR AND GUSTS IN EXCESS OF
50 KNOTS WILL BE POSSIBLE IN THE HEAVIEST CELLS. ACTIVITY WILL WANE
OVERNIGHT...WITH CLEARING EXPECTED OVER THE ENTIRE FA AFTER 09Z TO
VFR CONDITIONS.
