AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
103 PM EDT THU APR 25 2013

.UPDATE...
THE AVIATION SECTION HAS BEEN UPDATED BELOW

&&

.SYNOPSIS...
ISSUED AT 250 AM EDT THU APR 25 2013

HIGH PRESSURE CENTERED OVER THE SOUTHERN PLAINS STATES WILL BUILD
INTO THE OHIO VALLEY THROUGH THE END OF THE WORK WEEK. THIS WILL
BE DRY WEATHER WITH SLIGHTLY BELOW NORMAL TEMPERATURES.

A QUICK MOVING UPPER LEVEL WEATHER DISTURBANCE WILL PUSH TOWARD
INDIANA ON FRIDAY NIGHT AND SATURDAY...ONCE AGAIN BRINGING
CHANCES FOR RAIN THROUGH THE WEEKEND. MOISTURE APPEARS LIMITED
WITH THIS SYSTEM AND HEAVY RAIN IS NOT EXPECTED.

YET ANOTHER WEATHER DISTURBANCE WILL ARRIVE TUESDAY INTO WEDNESDAY
OF NEXT WEEK WILL HAVE SLIGHT POTENTIAL TO BRING A FEW SHOWERS TO
THE AREA...BUT IN A WELCOME BREAK...WIDESPREAD SIGNIFICANT
RAINFALL OF THE LAST WEEK OR SO APPEARS UNLIKELY FOR THE NEXT
SEVERAL DAYS.

&&

.NEAR TERM /THIS AFTERNOON/...

ISSUED AT 1037 AM EDT THU APR 25 2013

WEAK COLD FRONT CURRENTLY TRAVERSING THE FORECAST AREA THIS
MORNING. WITH ALL OF THE FORCING WELL TO THE NORTH OVER THE GREAT
LAKES...WINDSHIFT TO W/NW IS THE MAIN IMPACT FROM THE FRONTAL
PASSAGE. WHILE BULK OF THE CLOUDS ASSOCIATED WITH THE FRONT ARE
JUST GRAZING OUR NORTHERN COUNTIES THIS MORNING...COMBINATION OF
WEAK COLD ADVECTION AND AN 850MB THERMAL TROUGH THIS AFTERNOON
SHOULD ENABLE A CU FIELD TO FORM. CU WILL DIMINISH INTO THE EARLY
EVENING AS DIURNAL HEATING IS LOST. EXPECT A PERIOD WITH GUSTS TO
20-25KTS OVER THE NEXT SEVERAL HOURS WITHIN THE ZONE OF COLD
ADVECTION FOLLOWING THE FRONT.

TEMPS HAVE WARMED A LITTLE FASTER THAN PREVIOUSLY THOUGHT THIS
MORNING...RISING INTO THE MID/UPPER 40S AS OF 14Z. DESPITE THAT...
SUSPECT COMBINATION OF COLD ADVECTION AND INCREASED CU THIS
AFTERNOON WILL COUNTERACT THE QUICK RISE SO FAR THIS MORNING. WILL
LEAVE HIGH TEMPS IN THE MID/UPPER 50S AS IS.

ZONE AND GRID UPDATES OUT.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...

ISSUED AT 250 AM EDT THU APR 25 2013

MAIN FORECAST CHALLENGE DURING THIS PERIOD WILL BE TEMPS THROUGH
FRIDAY AND THEN RAIN CHANCES THROUGH SATURDAY NIGHT

DRY WEATHER IS EXPECTED TO CONTINUE TONIGHT THROUGH FRIDAY EVENING
AS A RIDGE OF HIGH PRESSURE BUILDS ALOFT. MOSTLY CLEAR SKIES ARE
EXPECTED TONIGHT AS A DRY COLUMN IS REVEALED BY FORECAST
SOUNDINGS. WITH AN UPPER RIDGE ALOFT AND HIGH PRESSURE AT THE
SURFACE...GOOD RADIATIONAL COOLING SET UP WILL BE IN PLACE AND
FROST FORMATION WILL BE PROBABLE. WILL HOLD OFF ON ANY ADVISORY AT
THIS POINT. GIVEN THE 850MB TEMPS A BLEND OF THE MAVMOS AND METMOS
WILL WORK FINE.

GOOD WARM AIR ADVECTION MOVES INTO THE AREA ON FRIDAY AS 850MB
TEMPS RISE TO NEAR 4C BY 18Z. FORECAST SOUNDINGS INDICATE SOME HIGH
CLOUDS MOVING INTO THE AREA AND CONVECTIVE TEMPERATURES WILL BE IN
THE 70S...WHICH WILL BE HARD TO REACH. THUS WILL AIM FOR PARTLY
CLOUDY SKIES DUE TO INVADING HIGH CLOUDS AND ONCE AGAIN A BLEND OF
THE MAVMOS AND METMOS WILL WORK JUST FINE.

GFS AND NAM THEN DEPICT A SHORT WAVE PUSHING TOWARD THE OHIO
VALLEY ON LATE FRIDAY NIGHT THROUGH SATURDAY. 295K GFS ISENTROPIC
SURFACE SHOWS GOOD UPGLIDE ON SATURDAY AS A SURGE OF SPECIFIC
HUMIDITIES NEAR 4 G/KG. FORECAST ALSO HINT AT A SATURATED DEEP
COLUMN BY 00Z SUN. THUS WILL TREND POPS HIGHER THROUGH SATURDAY
NIGHT. GIVEN THE WARM AIR ADVECTION AND EXPECTED CLOUDS AND PRECIP
WILL TREND LOWS WARMER THAN MAVMOS AND HIGHS COOLER.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...

ISSUED AT 250 AM EDT THU APR 25 2013

ENSEMBLES ARE IN REASONABLY GOOD AGREEMENT ON THE UPCOMING PATTERN
EARLY IN THE EXTENDED...BUT THERE ARE SOME DIFFERENCES WITH RESPECT
TO THE SYSTEM THAT MAY AFFECT THE AREA TOWARDS THE MIDDLE OF NEXT
WEEK.

RATHER WEAK UPPER TROUGH WILL BE IN THE PROCESS OF PASSING THROUGH
THE FORECAST ON AREA ON SUNDAY. WILL CONTINUE WITH CHANCE POPS ON
SUNDAY TO COVER THIS FEATURE.

BY EARLY NEXT WEEK...APPEARS AN UPPER RIDGE WILL BUILD INTO THE AREA
AS A TROUGH MOVES THROUGH THE NORTHERN ROCKIES AND PLAINS. WITH THE
UPPER RIDGE BUILDING IN...THINK PRECIPITATION CHANCES FOR AT LEAST
MONDAY AND TUESDAY ARE DIMINISHING. WILL KEEP MONDAY DRY AND TAKE
OUT POPS FOR TUESDAY.

ENSEMBLES ARE TRENDING SLOWER WITH THE SYSTEM AROUND THE MIDDLE OF
NEXT WEEK. SOME OF THE MEMBERS STILL BRING THIS SYSTEM INTO THE
MIDWEST BY NEXT WEDNESDAY...BUT THE MAJORITY STILL HAVE THIS TROUGH
IN THE PLAINS AT THAT TIME. A COUPLE OF MEMBERS EVEN SUGGEST THIS
TROUGH MAY STILL BE IN THE NORTHERN ROCKIES. WILL GO WITH CHANCE
POPS FOR NEXT WEDNESDAY TO COVER THE FASTER SOLUTIONS...BUT IF
TRENDS CONTINUE...NEXT WEDNESDAY MAY END UP BEING DRY AS WELL.

&&

.AVIATION /DISCUSSION FOR THE 25/1800Z TAF ISSUANCE/...

ISSUED AT 1250 PM EDT THU APR 25 2013

WEAK COLD FRONT MOVING THROUGH THE TAF SITES WILL CONTINUE TO
GENERATE LOW LEVEL CLOUDS THROUGH THIS AFTERNOON. HOWEVER...EXPECT
CONDITIONS TO STAY AT VFR CATEGORY THROUGH ENTIRE TAF PERIOD. WEST
WINDS WILL REMAIN BREEZY THROUGH SUNSET THIS EVENING WITH
SUSTAINED SPEEDS OF 12 TO 16 KTS AND GUSTS UP TO 30 KTS AND THEN
DIMINISH. WINDS WILL SHIFT TO THE SOUTHEAST LATE TONIGHT AT 4 TO
8 KTS. MID LEVEL CLOUDS WILL INCREASE LATE IN TAF PERIOD AS AN
UPPER LEVEL LOW APPROACHES FROM THE SOUTHWEST.
