AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
338 PM EDT THU MAY 27 2010

.SHORT TERM...
TONIGHT THROUGH FRIDAY NIGHT.

CONVECTION HAS BEEN ONGOING FOR A FEW HOURS NOW FROM PAULDING COUNTY
SOUTHWEST INTO BLACKFORD COUNTY. THE MAJORITY OF THE CELLS HAVE
BEHAVED AS EXPECTED WITH A OVERALL LACK OF WIND SHEAR...RESULTING IN
POCKETS OF HEAVY RAINFALL. ACROSS VAN WERT AND ALLEN
COUNTIES...SEVERAL STORMS HAVE CONTINUED TO REDEVELOP...WITH THE
INTERACTION OF OUTFLOW BOUNDARIES HELPING TO INTENSIFY A FEW STORMS.
ONE STORM BRIEFLY BECAME SEVERE...PRODUCING QUARTER SIZE HAIL IN
ALLEN COUNTY OHIO. STORMS WILL CONTINUE TO PULSE IN THESE AREAS OVER
THE NEXT COUPLE OF HOURS...BUT SHOULD WIND DOWN BY 00Z. HAVE OPTED
TO GO WITH A PRE 1ST PERIOD SCT MENTION IN THE FAR SE. HAVE ALSO
WENT WITH A SLGT CHC BACK TO THE NW TO ALONG A MONTICELLO TO
HILLSDALE LINE WITH THE MAIN PUSH OF DRIER AIR NW OF THIS
LINE...ENDING ANY THREAT FOR PRECIP.

SKIES SHOULD CLEAR OUT TONIGHT ONCE DIURNAL CU/CONVECTION WINDS
DOWN. THIS WILL LEAD TO A COOLER AND LESS HUMID NIGHT FOR MUCH OF
THE AREA..ESPECIALLY NW. BIT CONCERNED THAT LOWS MAY BE TOO COOL IN
THE NW BUT WILL LET THEM RIDE GIVEN DEWPTS IN THE 40S ATTEMPTING TO
SLIDE SOUTHEAST.

FRIDAY/FRIDAY NIGHT LOOKS TO BE A VERY NICE DAY. A GOOD DEAL OF
SUNSHINE SHOULD PREVAIL. CAN'T RULE OUT SOME FAIR WEATHER CU IN NE
AREAS WHERE MODELS SHOW SOME MODEST INSTABILITY. HIGHS WILL BE A FEW
DEGREES COOLER WITH LOWER HUMIDITIES. LOWS FRIDAY NIGHT WILL BEGIN
TO REBOUND SOMEWHAT AS MINOR PUSH OF HIGHER TEMPS ALOFT AND SLIGHTLY
HIGHER DEWPTS BEGIN TO ARRIVE ONCE AGAIN.

&&

.LONG TERM...
SATURDAY THROUGH THURSDAY...
PLEASANT START TO THE HOLIDAY WEEKEND. WEAK SFC RIDGING COMBINED
WITH STRONG UPPER RIDGE IN THE PLAINS/MID MS VALLEY WILL PROVIDE
AMPLE SUNSHINE AND WARM TEMPS AS LOW LEVEL THERMAL RIDGING WORKS
INTO THE AREA AND SUPPORTIVE OF MID 80S FOR HIGHS. AMPLIFIED PATTERN
WILL BECOME MORE ZONAL WITH TIME DEEP UPPER TROUGH OVER EASTERN
PACIFIC WORKS THROUGH THE INTERMOUNTAIN REGION THIS WEEKEND AND
COMBINES WITH WEAKER DISTURBANCE OVER GULF COAST TO FLATTEN UPPER
RIDGE. THIS WILL BRING NEXT FRONTAL BOUNDARY THROUGH THE AREA ON
MEMORIAL DAY. BEST UPPER LEVEL SUPPORT...FORCING AND DYNAMICS WILL
BE NORTH OF OUR AREA ALONG US/CANADIAN BORDER BUT MOISTURE TRANSPORT
VECTORS SUGGESTING DISTURBANCE OVER SE US WILL BECOME LESS ORGANIZED
WITH TIME AND ALLOW FRONT TO TAP INTO GULF MOISTURE AS IT REACHES
THE AREA ON MONDAY. MEDIUM RANGE MODELS ALSO INDICATING FAVORABLE
DIURNAL TIMING WHICH SHOULD AID IN THE DEVELOPMENT OF SCT SH/TSRA
AHEAD/ALONG FRONT. SFC HIGH PRESSURE SETTLES IN OVER THE REGION TUE
AND WED BEFORE NEXT SYSTEM BRINGS PRECIP CHANCES BACK INTO THE AREA
WED NITE/THU.

&&

.AVIATION...
VFR CONDITIONS TO PREVAIL AT KSBN AND MORE THAN LIKELY AT KFWA
THROUGH THE PERIOD. WEAK CONVERGENCE APPEARS TO FINALLY BE STIRRING
UP STORMS...BUT THESE HAVE BEEN SE OF KFWA AND WILL LIKELY REMAIN
THERE. LITTLE MORE THAN SOME AREAS OF CU AND MID CLOUDS WILL BE
AROUND SO NO SIG CHANGES.
