.UPDATE...
ISSUED AT 1221 PM CDT MON JUL 2 2012

UPDATED FOR AVIATION SECTION ONLY.

UPDATE ISSUED AT 1030 AM CDT MON JUL 2 2012

ISOLATED STORMS ALREADY BEGINNING TO FIRE UP ALONG THE MS RIVER
BETWEEN PAH AND STL AND UP ALONG THE I 64 CORRIDOR...WHERE CAPE
VALUES HAVE SOARED UP INTO THE 2000 TO 3000 J/KG CATEGORY. OPTED
TO UP POPS IN THESE ARES FOR THE MID/LATE MORNING INTO THE 20 TO 30
PERCENT RANGE. TEMPERATURES ALSO HAD SOARED QUICKER THAN EXPECTED
IN MANY LOCATIONS...SO ATTEMPTED TO ADJUST HERE ALSO.

&&

.SHORT TERM...(TODAY THROUGH WEDNESDAY NIGHT)
ISSUED AT 211 AM CDT MON JUL 2 2012

A FEW AREAS ACROSS THE QUAD STATE MAY GET LUCKY AGAIN TODAY AND
TUESDAY WHERE PRECIPITATION IS CONCERNED.

BASED ON THE POSITION OF WHATS LEFT OF THE UPPER LEVEL RIDGE AND
MID LEVEL TEMPERATURES...FEEL THAT CONVECTION WILL INITIALLY FIRE
OVER THE NORTHERN AND WESTERN SECTIONS OF OUR CWA AROUND MIDDAY...
THEN MIGRATE SLOWLY SOUTHWARD THROUGH THE AFTERNOON AS THE NOSE OF
THE RIDGE MOVES SLIGHTLY OFF TO THE SOUTHEAST. AGAIN MOST AREAS
WILL REMAIN DRY...BUT ANY STORMS THAT DO DEVELOP WILL BE CAPABLE
OF PRODUCING LOCALLY HEAVY RAINFALL.

SCATTERED STORMS WILL LIKELY LINGER INTO THE EVENING HOURS...BUT WITH
LACK OF HEATING/INSTABILITY SHOULD BE GONE BY MIDNIGHT. ON TUESDAY
COVERAGE OF CONVECTION SHOULD BE A TAD HIGHER AS A WEAK UPPER LEVEL
DISTURBANCE DIVES SOUTHEAST ACROSS OUR CWA. PRECIP CHANCES SHOULD
DROP OFF AGAIN TUESDAY NIGHT...THEN LINGER OVER THE EXTREME
EASTERN SECTIONS OF THE CWA BEFORE THE TRAILING EDGE OF THE UPPER
LEVEL DISTURBANCE CLEARS THE AREA.

EVEN WITH SMALL PRECIP CHANCES...TEMPERATURES SHOULD STILL MAX OUT
EACH AFTERNOON AT OR JUST BELOW THE CENTURY MARK WITH OVERNIGHT
LOWS ONLY DROPPING INTO THE MID 70S.

.LONG TERM...(THURSDAY THROUGH SUNDAY)
ISSUED AT 211 AM CDT MON JUL 2 2012

VERY HOT AND DRY CONDITIONS WILL PERSIST THROUGH THE LONG TERM.
UPPER LEVEL HIGH WILL STRENGTHEN AND BUILD EASTWARD THURSDAY AND
FRIDAY. LOW LEVEL FLOW WILL BE VERY WEAK...AND WARM AIR ADVECTION
WILL BE MINIMAL. HOWEVER...AIR MASS MODIFICATION WILL LIKELY OCCUR
OVER THE PARCHED GROUND IN THE EXTREME DROUGHT AREA ACROSS OUR
REGION. A BLEND OF MODEL GUIDANCE YIELDS HIGHS AROUND 100 EACH DAY.
WILL USE THIS MODEL BLEND FOR THE OFFICIAL FORECAST...BUT THIS MAY
END UP BEING CONSERVATIVE IF THE PAST SEVERAL DAYS ARE ANY
INDICATION OF THE IMPACT OF SOIL MOISTURE ON TEMPS. HEAT HEADLINES
WILL BE REQUIRED IF THIS IS THE CASE.

AS FOR PRECIP CHANCES...THE PATTERN WILL REMAIN A DRY ONE. THERE IS
A SLIGHT CHANCE OF STORMS THURSDAY OVER SW INDIANA AND WEST
KENTUCKY. THIS IS BASED ON INDICATIONS OF A WEAK VORT CENTER SLIDING
SOUTH ON THE FRONT SIDE OF THE UPPER RIDGE.

BY DAY 7 /SUNDAY/...THE UPPER RIDGE WILL BEGIN A WESTWARD MIGRATION
AS TROUGHING DEVELOPS OVER THE EASTERN STATES. MODELS ARE IN FAIRLY
GOOD AGREEMENT THAT A COLD FRONT WILL APPROACH FROM THE NORTH ON
SUNDAY. WILL CARRY SLIGHT CHANCE POPS AREA WIDE AHEAD OF THE FRONT.

BEYOND DAY 7...UNUSUALLY STRONG MODEL AGREEMENT CONTINUES. THE
MODELS CONTINUE TO ADVERTISE NORTHWESTERLY UPPER LEVEL FLOW OVER THE
OHIO VALLEY AND MID MISSISSIPPI VALLEY. THIS WILL RESULT IN AT LEAST
SLIGHT COOLING OVER OUR REGION...ALONG WITH AN INCREASED CHANCE OF
CONVECTION ASSOCIATED WITH DISTURBANCES IN THE NORTHWEST FLOW ALOFT.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1221 PM CDT MON JUL 2 2012

HAVE BEEN ADVISED THAT THE NAM MODEL HAS BEEN PERFORMING WELL WITH
AFTN CONVECTION PAST DAY OR SO. THEREFORE...DECIDED TO AT LEAST
MENTION VCTS UP NORTH AT KEVV/KOWB SITES...WHERE NAM FOCUSES BAND
OF CONVECTION THIS AFTERNOON INTO EARLY EVENING...NEAR DEW POINT
GRADIENT. ANOTHER REASON I WANTED TO GET SOME MENTION OF TS IN
THERE IS BECAUSE IF STORMS DO FORM WITH TEMPS UP NEAR 100...
STRONG/ERRATIC WINDS WOULD BE A MAJOR CONCERN.
