Area forecast discussion, Jul 19, 4:34 PM EST, 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
534 PM EDT THU JUL 19 2012

.SYNOPSIS...
A COLD FRONTAL BOUNDARY AND AN ASSOCIATED WAVE OF LOW PRESSURE
WILL APPROACH AND MOVE THROUGH THE AREA TONIGHT INTO FRIDAY. HIGH
PRESSURE WILL THEN MOVE INTO THE AREA FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
UPDATED THE FORECAST TO ADD HEAVY RAIN AND SEVERE POTENTIAL TO
PORTIONS OF THE AREA FOR THIS EVENING. IN ADDITION ADJUSTED
PRECIPITATION CHANCES BASED ON CURRENT TRENDS.

CLOUD COVER HAS DECREASED ACROSS SW POTIONS OF THE FA THIS
AFTERNOON. TEMPERATURES HAVE INCREASED ACROSS THE SW INTO THE 80S.
FURTHER WEST INTO CENTRAL INDIANA TEMPERATURES HAVE SOARED INTO
THE MIDDLE TO UPPER 90S. QUITE A FEW THUNDERSTORMS HAVE DEVELOPED
ACROSS SOUTHERN PORTIONS OF THE IND FA. EXPECT ADDITIONAL
THUNDERSTORM DEVELOPMENT ACROSS INDIANA AND FOR THIS ACTIVITY TO
MOVE INTO THE AREA THIS EVENING. SOME QUESTION EXISTS AS TO HOW
FAR EAST THE SEVERE THREAT WILL GO WITH CLOUD COVER ACROSS EASTERN
PORTIONS OF THE FA. IN ADDITION...HEAVY RAIN WILL BE POSSIBLE WITH
THE STORMS THIS EVENING. MENTIONED THE SEVERE AND HEAVY RAIN
THREAT IN THE HWO.

CANCELED THE HEAT ADVISORY FOR LOCATIONS WHERE MORE CLOUD COVER IS
PRESENT. CONTINUED THE HEAT ADVISORY AND EXCESSIVE HEAT WARNING
ACROSS SW PORTIONS OF THE FA WHERE CLEARING HAS OCCURRED AND
TEMPERATURES HAVE BEEN INCREASING.  WENT CLOSE TO GUIDANCE FOR LOW
TEMPERATURES FOR THE OVERNIGHT TIME FRAME.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
FRONTAL BOUNDARY WILL CONTINUE TO WORK THROUGH THE FA ON FRIDAY.
PRECIPITATION WILL TAPER OFF ACROSS THE FA FROM NW TO SE DURING
THE DAY. TEMPERATURES WILL BE COOLER FOR FRIDAY WITH PRECIPITATION
AND FRONTAL BOUNDARY. HIGH TEMPERATURES WILL BE IN THE LOW TO
MIDDLE 80S FOR FRIDAY. CLOUD COVER WILL DECREASE FRIDAY NIGHT AND
WITH COOLER AIR WORKING INTO THE AREA TEMPERATURES WILL DROP DOWN
INTO THE LOW TO MIDDLE 60S.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
MODEL AGREEMENT FOR THE EXTENDED PERIOD REMAINS IN FAIR SHAPE...IN
TERMS OF THE LARGE SCALE FEATURES. GFS ENSEMBLE MEANS CONTINUE TO
SHOW A RELATIVELY SMALL AMOUNT OF SPREAD THROUGH AT LEAST TUESDAY.
THE OVERALL PATTERN WILL BEGIN WITH THE CONTINUED DOMINANCE OF A
CENTRAL US RIDGE...WHICH LOSES SOME OF ITS INFLUENCE OVER THE
EASTERN US AS A TROUGH MOVES INTO THE NORTHEAST LATE IN THE EXTENDED
PERIOD.

HEIGHTS WILL BE RISING BY SATURDAY...AS THE RIDGE BUILDS ITS
INFLUENCE INTO THE OHIO VALLEY AND SHUNTS A TROUGH OFF TO THE EAST
AS IT DE-AMPLIFIES. WEAK SURFACE HIGH PRESSURE WILL ALSO DEVELOP AT
THIS TIME. ALTHOUGH THE RECENT RAINFALL MAY HAVE TEMPERED THE
EXTREMELY DRY CONDITIONS TO SOME SMALL DEGREE...IT IS STILL EXPECTED
THAT THE MODEL TEMPERATURES COULD BE TOO CONSERVATIVE ON
TEMPERATURES. TEMPS ON SATURDAY ARE CLOSE TO MET/NAM NUMBERS AND
THEN ABOVE MAV NUMBERS THROUGH EARLY IN THE WEEK. THIS WILL BRING A
RETURN OF 90 DEGREE TEMPERATURES ON MONDAY (AND PERHAPS ALSO IN THE
CINCINNATI METRO ON SUNDAY).

BEYOND MONDAY...THE RIDGE WILL FLATTEN SLIGHTLY...ALLOWING THE CWA
TO ENTER A NORTHWEST FLOW REGIME WITH OCCASIONAL DISTURBANCES MOVING
FROM THE NORTHERN MISSISSIPPI VALLEY THROUGH THE MID-ATLANTIC
STATES. WHILE THESE FEATURES WILL ALMOST CERTAINLY BRING SOME
PERIODS OF CONVECTION TO THE REGION...THESE INDIVIDUAL DETAILS ARE
DIFFICULT TO PICK OUT CORRECTLY THIS FAR IN ADVANCE. SO...SLIGHT
CHANCE POPS WILL BE USED FOR TUESDAY THROUGH THURSDAY...WITH JUST A
SLIGHT REDUCTION IN TEMPERATURES EACH DAY.

&&

.AVIATION /22Z THURSDAY THROUGH TUESDAY/...
FIRST ROUND OF CONVECTION THAT WAS ASSOCIATED WITH AN OVERNIGHT
COMPLEX HAS MOVED PRETTY MUCH THRU THE TAFS. NOW THE FOCUS SHIFTS
TO WHAT WILL HAPPEN LATER THIS AFTERNOON AND EVENING. CONSENSUS OF
THE MESOSCALE MODELS IS THAT CONVECTION WILL DEVELOP OUT OVER
IL/IN WHERE THE SUN HAS BROKE OUT AND THAT CONVECTION WILL WORK E
INTO THE TAFS. BROUGHT THE NEXT ROUND OF CONVECTION INTO THE WRN
TAFS AROUND 22Z AND HAVE IT EXITING THE TAFS BY 02Z.

CDFNT THEN PUSHES S OVERNIGHT. WINDS WILL TURN TO THE N WITH FROPA
AND EXPECT MVFR TO IFR CIGS TO DEVELOP AFT 08Z. CLDS WILL BE SLOW
TO BREAK FRIDAY MORNING...WITH MVFR CIGS EXPECTED THROUGH 18Z.
ALSO EXPECT MVFR FOG TO DEVELOP ALONG WITH THE MVFR CIGS.

OUTLOOK...THUNDERSTORMS POSSIBLE TUESDAY.

.ILN WATCHES/WARNINGS/ADVISORIES...
OH...HEAT ADVISORY UNTIL 8 PM EDT THIS EVENING FOR OHZ070.
     EXCESSIVE HEAT WARNING UNTIL 8 PM EDT THIS EVENING FOR OHZ077.
