AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
337 PM EDT WED APR 27 2011
.UPDATE...
THE SYNOPSIS...NEAR TERM...SHORT TERM...LONG TERM
AND HYDROLOGY SECTIONS HAVE BEEN UPDATED BELOW.
&&
.SYNOPSIS...ACTIVE WET WEATHER PATTERN CONTINUES ACROSS CENTRAL INDIANA. THIS
EVENING AND TONIGHT A SURFACE LOW PRESSURE SYSTEM WILL MOVE ACROSS
THE AREA AND BRING MORE HEAVY RAIN...THUNDERSTORMS...AND THE
POTENTIAL FOR SEVERE WEATHER TO THE AREA. THE FLASH FLOOD WATCH FOR
THE AREA HAS BEEN EXTENDED THROUGH LATE TONIGHT FOR THIS REASON. FOR
THURSDAY THE UPPER TROUGH WILL MOVE ACROSS THE AREA AND KEEP CHANCES
FOR RAIN SHOWERS GOING. BY THURSDAY NIGHT THE UPPER TROUGH WILL MOVE
OUT AND FINALLY ALLOW FOR SOME DRY WEATHER ACROSS CENTRAL INDIANA
FROM LATE THURSDAY NIGHT THROUGH SATURDAY. ON SATURDAY NIGHT
ANOTHER SYSTEM WILL ARRIVE BRINGING CHANCES FOR SHOWERS AND
THUNDERSTORMS TO THE AREA THROUGH MONDAY.
&&
.NEAR TERM /THIS EVENING AND TONIGHT/...
FORECAST FOCUS IS ON POPS...RAINFALL AMOUNTS AND POTENTIAL FOR
SEVERE. LEAD SURFACE LOW IS OVER E MICHIGAN WITH A FRONT EXTENDING
THROUGH CENTRAL INDIANA TO NE ARKANSAS WHERE THE TRAILING LOW IS
LOCATED AS OF 19Z. THE TRAILING LOW SHOULD BE SWINGING THROUGH THE
AREA BETWEEN 0 AND 6Z AND EXPECT THE HEAVIEST RAIN TO FALL ACROSS
THE AREA DURING THAT TIME. ACCORDING TO SATELLITE DERIVED VALUES
PRECIPITABLE WATER HAS DROPPED TO JUST OVER AN INCH BUT VALUES OF
AROUND 1.5 INCHES ARE JUST TO THE SOUTH AND COULD ADVECT IN AHEAD OF
THE LOW. THERE IS SOME WEAK INSTABILITY OVER THE SOUTHEASTERN HALF
OF THE AREA AS OF 19Z AS WELL...AND WIND SHEAR WILL INCREASE AS THE
SURFACE LOW TRAVERSES THE AREA...LOW LEVEL JET ARRIVES OVER THE
SOUTHEAST...AND UPPER JET AXIS MOVES ACROSS. THESE FACTORS COMBINED
JUSTIFY A RISK FOR SEVERE WEATHER THIS EVENING AND TONIGHT UNTIL
AFTER THE LOW MOVES THROUGH. THIS SAID...INSTABILITY IS WEAK AND
WITH ALL THE CLOUD COVER SHOULD REMAIN WEAK AND THUS BE A LIMITING
FACTOR.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
FORECAST FOCUS IS ON RAIN CHANCES. MODELS ARE IN GOOD AGREEMENT SO
WILL USE A CONSENSUS APPROACH. THE UPPER TROUGH WILL MOVE THROUGH
TOMORROW DURING THE DAY AND THINK THIS SHOULD PROVIDE ENOUGH FORCING
FOR SOME SHOWERS. THERE SHOULD NOT BE ANY INSTABILITY LEFT AT THAT
POINT AND AMPLE MOISTURE SHOULD BE GONE SO NOT EXPECTING LARGE
AMOUNTS OF QPF BUT INSTEAD A GRAY AND LIGHT SHOWERY DAY. KEPT
HIGHEST POPS IN THE NORTH CLOSEST TO THE UPPER LOW AND TAPERED TO
CHANCES IN THE SOUTH.
WITH SYSTEM MOTION TRENDING SLOWER HAVE ALSO ADDED A LOW CHANCE POP
IN THE EAST TAPERING TO SLIGHT CHANCE IN THE WEST FOR TOMORROW NIGHT
BEFORE 6Z. AFTER 6Z WILL BE DRY THROUGH THE REST OF THE SHORT TERM
AS HIGH PRESSURE BUILDS OVER THE AREA.
FOR TEMPERATURES GUIDANCE WAS VERY SIMILAR FOR THE MOST PART SO USED
A MAV/MET AVERAGE.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
THE LONG TERM SHOULD START OUT DRY WITH A RIDGE AXIS OVER THE AREA
AND MOVING OFF TO THE EAST. BY SATURDAY NIGHT THE COLD FRONT WILL
APPROACH AND BRING MORE CHANCES FOR THUNDERSTORMS TO THE AREA. THE
FRONT COULD GET HUNG UP BRIEFLY WITH A WARM FRONT EXTENDING OUT FROM
THE PLAINS AND THIS COULD KEEP THUNDER CHANCES IN THROUGH SUNDAY
NIGHT. ON MONDAY THE UPPER TROUGH SHOULD APPROACH AND WILL INCLUDE A
CHANCE OF SHOWERS FOR THAT BUT BY MONDAY NIGHT THE TROUGH AXIS
SHOULD BE MOVING EAST AND WILL GO DRY FROM THEN THROUGH WEDNESDAY.
OF NOTE AT THIS POINT IS THAT THE ECMWF IS SLOWER WITH THE PASSAGE
OF THE SYSTEM AND DEVELOPS A CUT OFF UPPER LOW ON TUESDAY WHICH
WOULD KEEP CHANCES FOR RAIN IN THE FORECAST LONGER...BUT AT THIS
POINT ENSEMBLES ARE FAVORING A MORE PROGRESSIVE PATTERN SO WILL
DISCOUNT THE ECMWF FOR NOW. TEMPERATURES SHOULD START WARMER THAN
AVERAGE ON SATURDAY...BE NEAR AVERAGE ON SUNDAY AND THEN DROP BELOW
AVERAGE AFTER FRONTAL PASSAGE FOR MONDAY AND TUESDAY.
&&
.AVIATION.../FOR 271818Z TAFS/...

WILL MOVE TO LAKE ONTARIO BY 12Z...BUT CONTROL WEATHER OVER AREA
