AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1208 AM CDT TUE AUG 23 2011

.DISCUSSION...
/350 PM CDT MON AUG 22 2011/

WEAK WAA REGIME...WHICH IS ATTEMPTING TO PUSH UNSTABLE AIR BACK
ACROSS CWA...COMBINED WITH WEAK DYNAMICS ASSOCIATED WITH NW FLOW
ALOFT...IS MAKING FOR A TRICKY PRECIPITATION FORECAST OVER THE NEXT
36 HOURS (AS EVIDENCE...SEE RENEGADE SHOWERS/ISOLD TSRA THAT DOTTED
E MO AND PARTS OF S CENTRAL IL THIS MORNING).  THE MUCH STRONGER
MORNING CONVECTION DROPPED SOUTH ACROSS WESTERN MISSOURI...AND THE
RESIDUAL EFFECTS OF THIS ACTIVITY (PRIMARILY ASSOCIATED WITH OUTFLOW
BOUNDARY) ARE NOW LOCATED OVER SW/S CENTRAL MO.

BELIEVE THAT THIS ONGOING ACTIVITY WILL CONTINUE TO DROP SE AND
REMAIN OUT OF OUR AREA THIS EVENING.  HOWEVER...AS WAA GRADUALLY
INCREASES LATER TONIGHT A CHANCE OF THUNDERSTORMS SHOULD RETURN TO
THE NW HALF OF THE CWA.  GIVEN HOW FAR EAST THIS MORNINGS PRECIP
REACHED THIS MAY NOT BE FAR ENOUGH...AND EVENING SHIFT WILL HAVE TO
MONITOR FOR POSSIBLE EXPANSION.

WITH THE AFOREMENTIONED PATTERN REMAINING IN PLACE THROUGH TUESDAY
NIGHT...HAVE CONTINUED LOW POPS ACROSS MOST OF THE AREA.  THESE
TRENDS WILL ALMOST UNDOUBTEDLY NEED TWEEKING WITH TIME...BUT
FINE-TUNING WILL PROBABLY BE LIMITED TO FIRST PERIOD WHEN PRECIP
TRENDS BECOME A BIT MORE CLEAR CUT.

IN THE TUESDAY NIGHT-WED TIME FRAME...PRECIPITATION THREAT SHOULD
TRANSITION FROM ELEVATED TO MORE SURFACE BASED AS THRUST OF ELEVATED
WAA/LIFT SHIFTS INTO THE OHIO VALLEY AND SURFACE WARM SECTOR SURGES
INTO OUR AREA.  AS MENTIONED YESTERDAY THE PRIMARY QUESTION FOR
WEDNESDAY AFTERNOON AND WED NIGHTS PRECIP IS WHETHER SURFACED BASED
CONVERGENCE AND WEAK DYNAMICS WILL BE ABLE TO BREAK WHAT IS PROGGED
TO BE A FAIRLY STOUT CAP.  AIRMASS WILL BECOME EXTREMELY UNSTABLE SO
IF CAP CAN BE BROKEN THE GOING CHANCE POPS WILL PROBABLY NOT BE HIGH
ENOUGH...BUT ON THE OTHER HAND IF CAN DOES HOLD THEY WILL BE TOO
HIGH. ONCE AGAIN...FINE TUNING THIS THREAT WILL HAVE TO WAIT UNTIL
ALL IMPORTANT SPECIFICS BECOME A BIT MORE CLEAR.

AS FAR AS TEMPERATURES ARE CONCERNED...IT CERTAINLY APPEARS THAT
WEDNESDAY WILL PROVIDE AREA WITH A TRUE TASTE OF LATE SUMMER HEAT
AND AND HUMIDITY.  THERMAL AXIS OF 22-26C AIR AT 85H SHOULD
CERTAINLY MEAN M-U 90S FOR MOST OF THE AREA...AND IF CAP DOESN'T
BREAK TOO SOON IN THE DAY WOULDN'T BE A BIT SURPRISED IF SOME SPOTS
IN THE CLIMATOLOGICALLY FAVORED AREAS OF CENTRAL/E CENTRAL MO HIT
THE CENTURY MARK.  THIS WILL ALSO MEAN THAT HEAT INDEX VALUES MAY
APPROACH ADVISORY CRITERIA...BUT WILL WAIT FOR ONE MORE MODEL
CYCLE TO PIN DOWN SPECIFICS OF THIS SCENARIO BEFORE GOING OUT WITH
HEADLINE. HOWEVER...WILL HIGHLIGHT HEAT INDEX VALUES BETWEEN 100
AND 110 IN BOTH THE HWO AND THE ZONES.

COLD FRONT SHOULD SWEEP THROUGH THE AREA WEDNESDAY NIGHT...ENDING
THE TSRA THREAT BY THURSDAY.   THE CHANGE IN AIRMASS BEHIND THIS
FRONT WILL NOT BE A HUGE FALL-LIKE COOL DOWN AND IN REALITY WITH THE
UPPER RIDGE HOLDING FIRM OVER THE NATIONS MIDSECTION TEMPERATURES
WILL REMAIN ABOVE NORMAL FOR THE REST OF THE WEEK.  HOWEVER...IT
SHOULD CERTAINLY BE ENOUGH TO LIMIT THE HIGH LEVELS OF HEAT AND
HUMIDITY TO WEDNESDAY.

WITH UPPER RIDGE HOLDING OVER THE CENTRAL CONUS WESTERLIES WILL BE
DISPLACED WELL TO THE NORTH. THE MEDIUM RANGE SOLUTIONS DO INDICATE
SHORTWAVE IN THE WESTERLIES WILL PUSH THROUGH UPPER MISSISSIPPI
VALLEY LATE FRIDAY AND SATURDAY...BUT WITH THE PRIMARY DYNAMICS N OF
OUR AREA WILL LEAVE FORECAST DRY DURING THIS TIME PERIOD.
HOWEVER...THERE IS GOOD AGREEMENT IN THE MEDIUM RANGE SOLUTIONS THAT
FAIRLY STRONG SHORTWAVE SHOUD DROP INTO THE AREA SUNDAY NIGHT AND
MONDAY...AND GIVEN THIS AGREEMENT HAVE ADDED TSRA TO FORECAST FOR
THIS TIME FRAME.

.AVIATION...
/1145 PM CDT MON AUG 22 2011/

THUNDERSTORMS CONTINUE TO BE THE PRIMARY CONCERN FOR THE NEXT
24-36 HOURS. VFR AND DRY CONDITIONS WILL PREVAIL ACROSS THE BI-
STATE REGION...BUT AM EXPECTING ISOLATED TO WIDELY SCATTERED
SHOWERS AND THUNDERSTORMS TO DEVELOP OVER THE AREA. CURRENTLY IT
LOOKS LIKE THE STORMS WILL DEVELOP NEAR OR EAST OF THE MISSISSIPPI
RIVER...BUT CONFIDENCE IS LOW AT THIS TIME. SCATTERED AFTERNOON
THUNDERSTORMS ARE ALSO POSSIBLE...PERHAPS MORE LIKELY...DURING THE
HEAT OF THE DAY IN COMBINATION WITH A PASSING UPPER LEVEL
DISTURBANCE.

SPECIFICS FOR KSTL...

VFR AND DRY CONDITIONS WILL PREVAIL AT LAMBERT FOR THE NEXT 24 TO
30 HOURS. ISOLATED SHOWERS OR THUNDERSTORMS MAY FORM NEAR OR EAST
OF THE MISSISSIPPI RIVER AROUND SUNRISE...BUT CONFIDENCE IS LOW
THAT THIS WILL HAPPEN. SCATTERED THUNDERSTORMS ARE MORE LIKELY
DURING THE AFTERNOON AS AN UPPER LEVEL DISTURBANCE MOVES ACROSS
THE REGION.
