AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1240 AM EDT THU APR 11 2013

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

&&

.SYNOPSIS...
ISSUED AT 420 PM EDT WED APR 10 2013

STORM CHANCES WILL CONTINUE THROUGH THURSDAY WITH A STRONG LOW
PRESSURE SYSTEM SLOWLY MOVING THROUGH THE MIDWEST. AFTER THAT
WEATHER WILL GET A LITTLE QUIETER AND TEMPERATURES COOLER FOR A FEW
DAYS. THE NEXT SYSTEM WILL MOVE IN AND STALL OUT FROM SUNDAY NIGHT
ON BRINGING MORE CHANCES FOR THUNDERSTORMS.

&&

.NEAR TERM /REST OF TONIGHT/...

ISSUED AT 1010 PM EDT WED APR 10 2013

SIGNIFICANT CHANGES HAVE BEEN MADE TO TEMPERATURES IN SEVERAL
UPDATES THIS EVENING AS OLD FRONT HAS SUNK MUCH FURTHER SOUTH THAN
PREVIOUSLY THOUGHT. THIS IS DUE IN PART TO THE NUMEROUS THUNDERSTORM
OUTFLOW BOUNDARIES FROM EARLIER TONIGHT. HAVE CUT LOW TEMPERATURES
BY SEVERAL CATEGORIES AT SOME LOCATIONS.

HOWEVER...DO EXPECT THE FRONT TO SLOW AND THEN REVERSE COURSE AS LOW
PRESSURE APPROACHES THE AREA. TRIED TO CAPTURE THIS IN HOURLY GRIDS
AS BEST AS POSSIBLE...BUT EXPECT ADDITIONAL UPDATES DURING THE NIGHT
AS SITUATION DEVELOPS.

MEANWHILE...LINE OF CONVECTION WITH MAIN COLD FRONT CONTINUES TO
MARCH STEADILY EAST AND WILL ARRIVE IN THE AREA AFTER MIDNIGHT.
CONVECTION ALSO CONTINUES NORTH OF THE OLD FRONT ACROSS THE NORTHERN
FORECAST AREA. INCREASED POPS DURING THE NIGHT AS LINE OF CONVECTION
MOVES IN.

COLD AIR ACROSS THE AREA IS VERY SHALLOW...WITH STRONG SOUTH WINDS
ABOVE IT. SEVERE WEATHER REMAINS POSSIBLE THIS EVENING AS ELEVATED
HAIL THREAT CONTINUES...AND EVEN SOME WIND GUSTS MIGHT BE ABLE TO
PUNCH THROUGH THE SHALLOW COLD AIR. THE SOUTHERN FORECAST AREA
REMAINS IN THE WARM SECTOR AND WILL SEE CHANCES FOR SEVERE WEATHER
CONTINUE AS LOW LEVEL JET INCREASES ACROSS THERE.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...

ISSUED AT 420 PM EDT WED APR 10 2013

SLOWER MOVEMENT OF THE COLD FRONT AND LOW PRESSURE SYSTEM THROUGH
THE AREA WILL ALLOW FOR THE SLIGHT CHANCE OF SEVERE WEATHER TO
CONTINUE ACROSS THE EASTERN HALF OF THE AREA INTO MIDDAY THURSDAY
UNTIL THE COLD FRONT FINALLY MOVES THROUGH. WITH THE LOW LEVEL JET
AND SOME POTENTIAL FOR A BIT OF INSTABILITY TO REMAIN AHEAD OF THE
FRONT THINK THE THREAT FOR DAMAGING WINDS AND HAIL IS STILL THERE.
ALSO HIGH PRECIPITABLE WATER VALUES REMAIN IN PLACE AHEAD OF THE
COLD FRONT...HENCE THE POTENTIAL FOR HEAVY RAIN WILL CONTINUE
THROUGH MIDDAY THURSDAY. INCREASED GUIDANCE ACROSS MOST OF THE AREA
WITH SLOWER FRONTAL MOVEMENT AND CONTINUED WARM SOUTHWESTERLY FLOW
EXCEPT FOR THE NORTH WHICH COULD BE ON THE NORTH SIDE OF THE
STATIONARY FRONT. POPS WILL BE HIGH AHEAD OF/ALONG THE COLD FRONT.
BY THURSDAY NIGHT POPS WILL DROP OFF SLOWLY AS SURFACE LOW MOVES OFF
TO THE NORTHEAST. CONTINUED WITH SLIGHT CHANCE RAIN IN THE NORTH ON
FRIDAY WITH CONTINUED CYCLONIC FLOW. FOR TEMPERATURES GENERALLY WENT
CLOSER TO RAW MODEL NUMBERS WITH FRONTAL PASSAGE AND THEN WENT TO
CONSENSUS FOR MORE STABLE PATTERN FRIDAY AND FRIDAY NIGHT.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...

ISSUED AT 247 PM EDT WED APR 10 2013

DRY COOL START TO THE WEEKEND AS THE UPPER TROUGH WILL BE IN THE
PROCESS OF LIFTING OUT OF THE OHIO VALLEY. WARM ADVECTION WILL
COMMENCE BY SATURDAY EVENING AS SURFACE HIGH PRESSURE SHIFTS OFF
TO THE EAST AND SOUTHERLY FLOW DEVELOPS. HIGHS ON SATURDAY LIKELY
TO REMAIN MOSTLY IN THE UPPER 40S AND LOWER 50S WITH TEMPS FALLING
INTO THE 30S SATURDAY NIGHT.

FOCUS FOR THE REMAINDER OF THE EXTENDED IS ON THE ARRIVAL AND
PASSAGE OF A WARM FRONT ON SUNDAY...BRINGING A RETURN TO MUCH
WARMER AND INCREASINGLY UNSETTLED CONDITIONS AS WE HEAD INTO EARLY
NEXT WEEK WITH THE BOUNDARY BECOMING NEARLY STATIONARY ACROSS THE
REGION. OP GFS CONTINUES TO BE AN OUTLIER WITH A MORE INTENSE LEAD
WAVE ALONG THE BOUNDARY AND CONSEQUENTLY...THE MODEL APPEARS TO BE
OVERDOING RAINFALL POTENTIAL WITH THE WARM FRONT ON SUNDAY. WILL
CONTINUE TO INDICATE ONLY LOW CHANCE POPS SUNDAY AND FOCUS THEM
MAINLY NORTH OF I-70. MODEL DIFFERENCES ABOUND THROUGH THE REST OF
THE EXTENDED AS THE FRONT WILL OSCILLATE ACROSS THE OHIO VALLEY
WITH WAVES TRAVERSING THE BOUNDARY. AT THIS POINT...WILL CARRY
CHANCE FOR THUNDERSTORMS FROM MONDAY THROUGH WEDNESDAY. HIGH
TEMPS WILL RETURN INTO THE 60S AND 70S DURING THE PERIOD...
POSSIBLY EVEN WARMER SHOULD THE BOUNDARY SET UP FURTHER NORTH IN
THE LOWER GREAT LAKES.

&&

.AVIATION /DISCUSSION FOR 110600Z TAF ISSUANCE/...
ISSUED AT 1240 AM EDT THU APR 11 2013

AREA OF THUNDERSTORMS WILL LIFT NORTHEAST ACROSS THE TERMINALS
STARTING AT ISSUANCE TIME. THE RAPID REFRESH REFLECTIVITY PROGS ARE
DOING A REASONABLE JOB WITH TIMING WITH TEMPO THUNDERSTORMS EXPECTED
TO END AFTER 09Z AT HUF AND LAF AND AFTER 12Z AT IND AND BMG. FRONT
THAT DROPPED SOUTH ACROSS ALL BUT BMG SHOULD RETURN NORTH EARLY AS
LOW PRESSURE NEAR ST. LOUIS LIFTS NORTHEAST. ASSOCIATED COLD FRONT
SHOULD THEN SWEEP EAST AND REACH HUF AND LAF AROUND 14Z AND IND AND
BMG AROUND 17Z. STILL...SHOWERS AND POSSIBLY THUNDERSTORMS EXPECTED
FOR A FEW HOURS AFTER FROPA. WINDS SHOULD SHIFT FROM EAST TO
SOUTHEAST...SOUTH AND THEN FINALLY SOUTHWEST AS THE FRONT CURRENTLY
ACROSS CENTRAL INDIANA LIFTS NORTH AND FINALLY THE COLD FRONT MOVES
THROUGH. CEILINGS SHOULD RETURN TO VFR BUT DETERIORATE TO MVFR OR
WORSE IN THE THUNDERSTORMS AND BEHIND THE COLD FRONT. WINDS WILL
INCREASE TO AROUND 10 KNOTS WITH GUSTS TO NEAR 20 AFTER THE COLD
FRONT AND WITH PERHAPS HIGHER GUSTS IN THUNDERSTORMS.
