AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1136 PM CDT SAT JUN 30 2012

.UPDATE...
ISSUED AT 925 PM CDT SAT JUN 30 2012
SCATTERED CONVECTION HAS INCREASED IN COVERAGE OVER THE LAST 60
MINUTES IN THE BROAD WARM ADVECTION ZONE NEAR THE QUASI-
STATIONARY FRONTAL BOUNDARY PRIMARILY ALONG AND NORTH OF A MOB-
PPQ LINE...ALTHOUGH MUCH MORE ISOLATED SHOWERS HAVE GOTTEN AS FAR
S AS JEF-3LF LINE. SEE NO REAL REASON FOR THIS ACTIVITY TO WANE
OVER THE NEXT FEW HOURS...BUT THINK AN ADDITIONAL THUNDERSTORM
THREAT MAY EVOLVE IN PARTS OF OUR CWA FROM COMPLEX OVER NE KS.
GIVEN THE EXTREMELY UNSTABLE AIRMASS ALONG AND N OF THE BOUNDARY
DON'T SEE ANY STRONG REASON FOR IT TO TOTALLY DISSIPATE...SO TO
ACCOUNT FOR THIS THREAT HAVE ALSO PULLED CHANCE POPS SOUTH TO
ENCOMPASS COU AREA. TREND/MOVEMENT OF TONIGHTS CONVECTION COULD
HAVE IMPACT ON SUNDAYS FORECAST...BUT SINCE WE ARE JUST NOW
GETTING A GLIMPSE OF 00Z RUNS AND SINCE THESE CHANGES WILL BE
MESOSCALE-DRIVEN...HAVE NOT MADE ANY CHANGES TO SUNDAYS FORECAST
AT THIS TIME.

(SUMMARY)
STNRY FRONT DRAPED ALONG THE IA/MO BORDER EAST INTO CNTRL IL FROM AN
AREA OF LOW PRESSURE LOCATED ALONG THE KS/NE BORDER. SCATTERED
CONVECTION IS ONGOING THIS AFTERNOON ALONG AND NORTH OF THIS BNDRY.
UPPER RIDGE STILL IN CONTROL OF THE SOUTHERN HALF OF THE CONUS.
THERE ARE A FEW THAT HAVE FORMED ACROSS NE MO AND W CNTRL IL IN THE
LAST HOUR OR SO ALONG AN OUTFLOW BNDRY.

(TONIGHT THRU TUESDAY)
BIG QUESTION FOR THIS EVENING IS HOW FAR SE WILL THE SHRA ACTIVITY
MAKE IT. IT APPEARS TO BE RIDING ALONG THE EDGE OF THE CAP AND HAS
FORMED WHERE 700 MB TEMPS ARE 10-12C. THIS GRADIENT EXTENDS SE ALONG
THE RIVER. EXPECT THIS PRECIP TO DIMINISH AFTER SUNSET. ATTENTION
THEN TURNS TO THE ONGOING CONVECTION ACROSS NE. THIS SHOULD GET A BOOST
FROM A WEAK SHORT WAVE AND CONSOLIDATE INTO ONE OR MORE MCS/S LATER
THIS EVENING AND TRACK EAST ALONG THE FRONTAL BNDRY. THE BIG QUESTION
IS HOW FAR SOUTH WILL THIS ACTIVITY GET. DON/T EXPECT MAIN AREA OF
PRECIP TO GET INTO OUR CWA...THOUGH HAVE KEPT CHANCE POPS IN ACROSS
NE MO AND WEST CNTRL IL THRU TONIGHT. FRONT BEGINS TO MOVE NORTH ON
SUNDAY AS UPPER HEIGHTS BEGIN TO BUILD BACK INTO THE AREA. SUNDAY
AND MONDAY THE HEAT CONTINUES WITH 850 TEMPS IN THE 22-25C RANGE AND
MIXING HEIGHTS IN EXCESS OF 800 MB PUTS HIGHS AOA 100. SOME OF THE
GUIDANCE TRIES TO BRING A DISTURBANCE OUT OF TX INTO THE STHRN CWA
ON TUESDAY WITH CLOUDS PRECIP AND COOLER TEMPS. HAVE A HARD TIME
BELIEVING THAT SYSTEM WILL TRACK THRU THE MIDDLE OF THE UPPER LEVEL
RIDGE...SO AM DISCOUNTING THAT SCENARIO. ATTM...TUESDAY CONTINUES
THE STATUS QUO WITH LOW/MID 20C 850 TEMPS AND HIGHS NEAR 100. DUE TO
THE UNCERTAINTY ABOUT TUESDAY...HAVE OPTED TO LET THE GOING
HEADLINES RIDE AND CONTINUE AS IS THRU MONDAY.

WENT AT OR ABOVE THE WARMEST GUIDANCE (MET) AS THIS HAS WORKED WELL
FOR THE PAST SEVERAL DAYS.

(TUESDAY NIGHT THRU SATURDAY)
UPPER RIDGE REGAINS FIRM CONTROL OF THE CENTRAL US WITH THE 588
HEIGHT LINE WELL TO THE NORTH OF THE FA. ALL MODEL GUIDANCE IS IN
AGREEMENT WITH THIS SCENARIO. 850 TEMPS REMAIN 22-26C THRU THE
PERIOD WHICH RESULTS IN MAX TEMPS IN THE UPPER 90S TO LOW 100S INTO
NEXT WKND. DROUGHT CONDITIONS AND FIRE WEATHER CONCERNS WILL CONTINUE
UNTIL THERE IS A PATTERN CHANGE.
