Area forecast discussion, May 13, 2:30 PM EDT, 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
230 PM EDT FRI MAY 13 2011

.AVIATION...
A WEAK BOUNDARY WILL LIFT NORTH AS COOLER AIR SPREADS SOUTH OVER
LAKE MICHIGAN. A SFC LOW WILL REMAIN OVER THE AREA AS LIFT
INCREASES OVER THE AREA. EXPECT PRECIPITATION TO DEVELOP OVER THE
AREA AND PERSIST THROUGH THE END OF THE TAF PERIOD. CONDITIONS
SHOULD BE COME IFR BY LATE IN THE PERIOD.

&&

.PREV DISCUSSION... /ISSUED 317 AM EDT FRI MAY 13 2011/

SHORT TERM...

CLOSED LOW OVER NRN KS THIS MORNING EXPECTED TO CONTINUE MOVG SLOWLY
ESE TO THE LWR OH VALLEY BY SAT MORNING. BROAD AREA OF SFC LOW
PRESSURE AND ASSOCIATED CDFNT FROM WI-KS SHOULD ALSO MOVE ESE
TODAY AS THE UPR LOW APPROACHES. MOISTURE CONVERGENCE ALONG THIS
FRONT EXPECTED TO HELP GENERATE SOME MODERATE INSTABILITY...ESPCLY
ACROSS SE 1/2 OF CWA THIS AFTN AND PROVIDE WK FORCING FOR SCT
TSTMS. LIGHT WINDS WILL MAKE THESE STORMS SLOW MOVERS AND WITH
PRECIP WATER STILL >1" OVER THE AREA... STORMS COULD DUMP SOME
LOCALLY HEAVY RAINFALL.

MOVEMENT OF THE UPR LOW OVER THE REMAINDER OF THE WEEKEND
BECOMES MORE UNCERTAIN AS 00Z GFS LIFTS THE LOW NORTH INTO
CENTRAL INDIANA WHILE NAM CONTS A SLOW ESEWD TRACK ACROSS KY. BOTH
SOLUTIONS SUGGEST POTENTIAL FOR HEAVY RAINFALL IN DEFORMATION ZONE
NORTH OF THE UPR LOW AND WHILE THIS SEEMS REASONABLE THE
CONSIDERABLY DIFFERENT TRACKS FROM THE MODELS MAKE DETERMINING
LOCATION OF THE HEAVY RAINFALL QUESTIONABLE ATTM AND THUS HAVE
A BROAD BRUSH MODERATE QPF.

TEMPS WILL REMAIN WELL ABOVE NORMAL TODAY, BUT THERMAL RIDGE WILL
MOVE TO THE EAST SO EXPECT HIGHS WILL BE A LITTLE COOLER THAN
YDAY... IN THE L-M80S EXCEPT ONLY IN THE M70S NEAR LM WHERE WINDS
WILL GO NW THIS MORNING. THIS NW-SE COOL-WARM GRADIENT SHOULD
PERSIST OVER THE WEEKEND AS BROAD SFC LOW TO OUR WEST THIS MORNING
DEEPENS OVER OH AND BECOMES STNRY WITH STRONGEST CAA REMAINING OVER
NW PORTION OF THE CWA THROUGH THE WEEKEND.

LONG TERM...SUNDAY THROUGH THURSDAY

BLOCKED FLOW PATTERN ACROSS NOAM WILL PERSIST THROUGH THE
PERIOD...WITH BELOW NORMAL TEMPS EXPECTED AS A BROAD CENTRAL CONUS
UPPER TROUGH SHIFTS SLOWLY EWD WITH AN OMEGA TYPE BLOCKING RIDGE
SETTING UP ACROSS THE HIGHS PLAINS AND CENTRAL CANADA.

THE LATEST WATER VAPOR LOOP SHOWS TWO DISTINCT MID LEVEL
CIRCULATIONS...ONE ACROSS KANSAS AND ANOTHER ACROSS MANITOBA. LATEST
MODEL GUIDANCE PROPAGATES THE KANSAS WAVE EWD INTO THE OH VALLEY BY
SUNDAY...WHILE COINCIDENTALLY DROPPING THE MANITOBA WAVE SWD INTO
THE MID MS VALLEY. THE RESULT WILL BE A DEEPENING AND INTENSIFYING
FRONTAL CIRCULATION AND INCREASING MID LEVEL DEFORMATION FORCING
ACROSS THE SOUTHERN GREAT LAKES...WITH A BAND OF RAIN EXPECTED TO
PIVOT SEWD THROUGH THE FA SUNDAY INTO SUNDAY NIGHT. BEST CHANCES
APPEAR TO BE IN THE NORTH SUNDAY AND ACROSS SOUTHEASTERN PORTIONS OF
THE FA SUNDAY NIGHT.

THE INTERACTION OF THE TWO ABOVE MENTIONED PV ANOMALIES...AND
SEVERAL MORE IMPULSES DIVING SWD AROUND THE WESTERN PERIPHERY OF THE
UPPER TROUGH...WILL LIKELY COMBINE TO CARVE OUT A HIGHLY ANOMALOUS
DEEP CLOSED UPPER LOW SOMEWHERE ACROSS THE EASTERN US BY THE MIDDLE
OF NEXT WEEK. AS EXPECTED...MODELS DIFFER GREATLY ON
TIMING/PLACEMENT AND HOW MUCH RETROGRESSION TAKES PLACE. WITH THIS
SPREAD WILL MAKE NO CHANGES BEYOND MONDAY. THIS LEAVES US WITH AN
OPTIMISTIC DRY FCST TUESDAY THROUGH THURSDAY. POPS MIGHT EVENTUALLY
BE NEEDED IF WESTERN TRENDS OF THE OPERATIONAL ECMWF AND GFS
CONTINUE. REGARDLESS...CHANCES FOR MORE WIDESPREAD HEAVIER RAINFALL
WILL RESIDE EAST OF THE AREA GIVEN EXPECTED ORIENTATION OF MASS
FIELDS AND DEEPER MOISTURE EAST OF FA AND PV ANOMALY.

AVIATION.../06Z TAFS/
ISOLATED SHOWERS OVER THE AREA EARLY THIS MORNING WITH CONSIDERABLE
MID/HIGH LEVEL DEBRIS CLOUDS. SOME ELEVATED INSTABILITY IN PLACE SO
ISOLATED CONVECTION MAY PERSIST OVERNIGHT... BUT POPS TOO LOW TO
MENTION IN TAFS. EXPECT CLOUD COVER WILL LIMIT RADIATIONAL COOLING
AND REMOVED BR RESTRICTION FROM SBN TAF FOR EARLY THIS MORNING.
CDFNT MOVG INTO THE AREA THIS AFTN SHOULD CAUSE SCT TSTMS. AGAIN
GIVEN JUST SCT POPS HELD OFF ADDING TO TAFS ATTM, BUT DID MENTION
CB'S. CONVECTION EXPECTED TO TRANSITION TO MORE WIDESPREAD SHOWERS
TONIGHT AS DEFORMATION ZONE NE OF APCHG UPR LOW OVERSPREADS THE
AREA. THIS SHOULD LOWER FLYING CONDITIONS INTO MVFR RANGE OR LOWER
LATE TONIGHT.
