AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
254 AM EDT THU JUL 19 2012

.UPDATE...
THE LONG TERM SECTION HAS BEEN UPDATED BELOW

&&

.SYNOPSIS...
ISSUED AT 221 AM EDT THU JUL 19 2012

ANOTHER ACTIVE WEATHER DAY IS IN STORE FOR TODAY...INCLUDING HOT
TEMPERATURES AND CHANCES FOR THUNDERSTORMS AS AN AREA OF LOW
PRESSURE PUSHES ACROSS THE STATE TODAY AND TONIGHT.

COOLER HIGH PRESSURE IS EXPECTED TO ARRIVE ON FRIDAY TO START THE
WEEKEND...BRINGING TEMPERATURES CLOSER TO NORMAL ALONG WITH DRY
WEATHER START THE WEEKEND.

ANOTHER FRONTAL BOUNDARY WILL PUSH IN TO THE AREA ON MONDAY NIGHT
THROUGH WEDNESDAY BRINGING MORE CHANCES FOR SHOWERS AND
THUNDERSTORMS.

&&

.NEAR TERM /TODAY/...
ISSUED AT 221 AM EDT THU JUL 19 2012

SURFACE ANALYSIS EARLY THIS MORNING SHOWS LOW PRESSURE OVER SE
IOWA. TSRA WERE BLOWING UP AHEAD OF THE LOW OVER NORTHERN ILLINOIS
AND SOUTHERN WISCONSIN. RADAR SHOWED A FEW TSRA OVER SERN PARTS OF
CENTRAL INDIANA SLOWLY DRIFTING SOUTHEAST. SURFACE FLOW ACROSS THE
AREA REMAIN SOUTHERLY ACROSS THE AREA AS DEW POINT TEMPERATURES
WERE IN THE MOIST UPPER 60S TO AROUND 70. SEVERAL OUTFLOW
BOUNDARIES WERE FOUND ACROSS THE AREA DUE TO EARLIER AND ONGOING
CONVECTION.

MAIN FORECAST CHALLENGE TODAY WILL BE POPS AND TEMPS.

BOTH THE GFS AND THE NAM SUGGEST AN UPPER SHORT WAVE OVER IA TO
SLOWLY PUSH TOWARD INDIANA TODAY...TRIGGERING TSRA. RECENT RADAR
TRENDS ALREADY INDICATE THAT THIS IS THE CASE AS A THIN LINE OF
THUNDERSTORMS CONTINUES TO DEVELOP OVER WEST CENTRAL ILLINOIS.

NAM FORECAST SOUNDINGS REMAIN VERY STEEP TODAY THROUGH 18Z WITH
FAVORABLE INSTABILITY AND 700MB TEMPS NEAR 10C...ALTHOUGH GIVEN
OUR VERY WARM AIR MASS IT DOES NOT APPEAR A CAP IS IN PLACE.
MODELS ALSO AGREE THAT AN 850MB THERMAL RIDGE WILL BE IN PLACE
TODAY ACROSS INDIANA...AHEAD OF THE LOW...WITH 850 TEMPS NEAR 20C
AGAIN. THUS ANY SUNSHINE SHOULD QUICKLY HEAT AND DESTABILIZE THE
COLUMN...NOT TO MENTION THE ADVECTING FORCING ASSOCIATED WITH THE
SHORT WAVE. CLOUDS AND SCT PRECIP IN THE AREA SHOULD PREVENT
TRIPLE DIGITS IN MOST AREAS...HOWEVER THE SW FORECAST AREA...AS IT
REMAINS FARTHEST AWAY FROM THE DYNAMICS AND ONGOING PRECIP. THUS
TRIPLE DIGITS ARE POSSIBLE THERE AND A HEAT ADVISORY WILL BE NEEDED.

SINCE THE VERY WARM AIR MASS REMAINS IN PLACE AS THE FRONTAL
BOUNDARY TO THE NORTH DOES NOT ARRIVE LATE THIS AFTERNOON AND
EVENING...AND GIVEN THE STRONG FORCING AND UNSTABLE AIR MASS WILL
TREND POPS HIGH THAN GUIDANCE...PARTICULARLY ACROSS THE NORTH.
WILL ALSO TREND HIGH TEMPS AT OR ABOVE METMOS...PARTICULARLY
ACROSS THE SOUTHWEST AND SOUTH AS THOSE LOCATIONS WILL HAVE THE
MOST AMOUNT OF HEATING PRIOR TO THE FRONTAL ARRIVAL.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
ISSUED AT 221 AM EDT THU JUL 19 2012

MODELS ARE IN PRETTY GOOD AGREEMENT WITH THE OVERALL PATTERN AND
WILL USE A BLEND. MAIN FORECAST CHALLENGE WILL BE POPS TONIGHT AND
THEN TEMPS STARTING ON FRIDAY.

THE PREVIOUSLY MENTIONED UPPER SHORT WAVE WILL BE DEPARTING
CENTRAL INDIANA THIS EVENING. BOTH THE GFS AND THE NAM SUGGEST THE
SURFACE LOW WILL STILL BE LINGERING ACROSS CENTRAL INDIANA AT
00Z...NOT EXITING THE AREA WITH IT/S ASSOCIATED COLD FRONT UNTIL
AFTER 06Z...AT LEAST. TIME HEIGHT SECTIONS CONTINUE TO INDICATE
GOOD LOWER AND MIDDLE LEVEL MOISTURE WITH GOOD VV NEAR
00Z...HOWEVER THE COLUMN COULD END UP BEING WORKED OVER BY THAT
POINT BY PREVIOUS CONVECTION. FORECAST SOUNDINGS CONTINUE TO
INDICATE SOME INSTABILITY AS OF 00Z BUT AGAIN...IF THE PREVIOUS
CONVECTION GETS GOING...THAT WILL LIKELY BE LOST. THUS CONFIDENCE
IS LOW ON SPECIFIC TIMING AND ORGANIZATION. STILL GIVEN THE
DYNAMICS ALOFT AND THE LOWER LEVEL CONVERGENCE WILL NEED TO INCLUDE
POPS CLOSE TO GUIDANCE THROUGH 06Z...AND TREND TOWARD DRY AFTER
THAT. BEST POPS WILL BE ACROSS THE SOUTHEAST...WHERE PROPAGATION
OF THE SYSTEM WILL TAKE THE LONGEST. AS FOR TEMPS WILL STICK CLOSE
TO A BLEND OF THE MAVMOS AND MET.

COOL HIGH PRESSURE ARRIVES ON FRIDAY AS THE FORECAST SOUNDINGS AND
TIME HEIGHT DRY OUT ALOFT. THE MODELS DO HINT AT SOME TRAPPED
LOWER LEVEL MOISTURE ON FRIDAY...BUT WITH AN INVERSION
ALOFT...PRECIP IS NOT EXPECTED. FURTHERMORE AS THE STRONG JULY SUN
WORKS ON THAT LOWER LEVEL CLOUD DECK...EXPECT IT TO CONTINUE TO
DIMINISH AS FRIDAY GOES ON AS DRY AIR CONTINUES TO WORK INTO THE
STATE ON NORTH WINDS. WILL TREND HIGHS ABOVE MAVMOS AND METMOS DUE
TO THE VERY DRY CONDITIONS THAT CONTINUE TO LINGER ACROSS THE AREA.

ON FRIDAY NIGHT THROUGH SATURDAY NIGHT...RIDGING IS EXPECTED TO
BUILD ALOFT ACROSS INDIANA AND THE GREAT LAKES. GOOD SUBSIDENCE IS
SEEN IN THE MID LEVEL WHILE A STRONG AREA OF HIGH PRESSURE REMAINS
IN CHARGE AT THE SURFACE. FORECAST SOUNDINGS SHOW UNATTAINABLE
CONVECTIVE TEMPERATURES...THUS MOSTLY CLEAR NIGHTS AND A SUNNY
SATURDAY IS EXPECTED. WILL TREND ALL TEMPS WARMER THAN GUIDANCE
BASED UPON HOW WARM AND DRY WE HAVE BEEN.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...

ISSUED AT 250 AM EDT THU JUL 19 2012

SEE SAW PATTERN TO CONTINUE NEXT WEEK SIMILAR TO THIS WEEK WITH
COUPLE DRY DAYS SUNDAY AND MONDAY. STORM CHANCES RETURN AS CLUSTERS
OR MCS ACTIVITY IN NORTHWEST UPPER FLOW TUESDAY AND WEDNESDAY
AHEAD OF REAL STRONG SURGE OF HEAT PRIOR TO NEXT COOL FRONT
ARRIVAL THURSDAY NIGHT OR FRIDAY.

UNRELENTING HEAT REBUILDS STARTING AT LOW 90S SUNDAY AND BACK
INTO THE MID AND UPPER 90S BY WEDNESDAY. WOULD NOT BE SURPRISED IF
WE DONT HIT TRIPLE DIGIT HIGHS IN WESTERN COUNTIES WEDNESDAY AND
THURSDAY. AS BEFORE HAVE GONE ABOVE MOS GUIDANCE ON MAX TEMPS AS
THEY YET REMAIN UNABLE TO CAPTURE DROUGHT INDUCED HEAT.

MODELS ACTUALLY IN FAIRLY GOOD AGREEMENT REGARDING PRECIPITATION
CHANCES AS FRONTAL BOUNDARY SETS UP SOUTHERN GREAT LAKES TO UPPER
OHIO VALLEY AND SERIES OF SHORT WAVES PRODUCING DAILY MCS COMING
DOWN RIDGE. BEST RAIN THREATS WILL BE IN MICHIGAN AND OHIO WHILE
HERE IN INDIANA WESTERN COUNTIES MAY AGAIN BE TOO DEEP INTO THE
CORE OF THE RIDGE AND MISS MUCH OF THIS RAIN WHILE NORTHERN AND
EASTERN COUNTIES GET A COUPLE GOOD SHOTS AT SCATTERED LOCALLY
HEAVY RAINS LIKE THE LAST FEW DAYS THIS WEEK.

&&

.AVIATION /FOR 190600Z TAF ISSUANCE/...
ISSUED AT 1230 AM EDT THU JUL 19 2012

WIDELY SCATTERED THUNDERSTORMS HAVE LINGERED ACROSS THE SOUTHERN
HALF OF CENTRAL INDIANA...WHILE A MUCH MORE IMPRESSIVE AREA OF
STORMS WAS MOVING ACROSS NORTHERN ILLINOIS INTO EXTREME NORTHERN
INDIANA AND THE SOUTHERN GREAT LAKES.  MOST OF THE ACTIVITY APEARS
TO BE STEADY STATE OR INCREASING IN STRENGTH AND COVERAGE. ALL BUT
KHUF APPEARS IN LINE FOR POTENTIAL STORMS PRIOR TO DAYBREAK.

RAPID REFRESH MODEL BRINGS AREA OF STORMS INTO KLAF AREA BY 11Z AND
KIND AND KHUF AREAS BY 14Z. THUNDERSTORMS WILL NOT BE CONTINUOUS.
HOWEVER...SEVERAL ROUNDS MAY AFFECT KIND AND KLAF MUCH OF THE DAY
THURSDAY WITH LESSER CHANCES AT KHUF AND KBMG.

MODELS INDICATE A COLD FRONT OVER EXTREME NORTHERN ILLINOIS AND
SOUTHERN LOWER MICHIGAN WILL MOVE SOUTH ACROSS CENTRAL INDIANA
THURSDAY EVENING AND THUNDERSTORMS SHOULD DIMINISH FROM THE NORTH
AFTER FRONT MOVES THROUGH.  NAM MODEL INDICATES MVFR CEILINGS MAY
SPREAD IN BEHIND THE FRONT OVER NORTHERN AND CENTRAL AREAS LATER
THURSDAY NIGHT.

WINDS WILL BECOME SOUTHWEST NEAR 10 KNOTS THURSDAY AND THEN
NORTHWEST AT 8 KNOTS OR LESS THURSDAY NIGHT BEHIND COLD FRONT.

A PERIOD OF MVFR FOG IS NOT OUT OF THE QUESTION LATE THURSDAY
TONIGHT...BUT HIGH CLOUDS MAY LIMIT THIS AND HAVE REMOVED MENTION
FROM MOST TAFS.
