AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
102 PM CDT THU AUG 2 2012

.UPDATE...
ISSUED AT 1020 AM CDT THU AUG 2 2012

QUICK UPDATE TO THE FORECAST TO INCREASE POPS AND DECREASE TEMPERATURES...
ESPECIALLY ACROSS C MO. THICK MIDLEVEL CLOUDS AND AREA OF RAIN
MOVIG IN AHEAD OF MCV WILL KEEP TEMPERATURES COOLER THAN THE
PREVIOUS FORECAST. FURTHER EAST...ONLY COSMETIC CHANGES MADE AS
EVOLUTION OF MCV AND ASSOCIATED PRECIPITATION IS STILL A BIT
UNCERTAIN AT THIS TIME.

GOSSELIN

&&

.SHORT TERM...
ISSUED AT 327 AM CDT THU AUG 2 2012
(TODAY THROUGH SATURDAY)

CHALLENGING FORECAST THIS MORNING WITH HIGH BUST POTENTIAL THROUGH
SATURDAY.  THE EVER-PRESENT UPPER LEVEL RIDGE IS ALREADY BEING
SUPPRESSED BY THE SHORTWAVES WHICH RIPPLED BY YESTERDAY AND ANOTHER
STRONGER WAVE IS NOW ROUNDING THE CORNER OVER EASTERN NEBRASKA
HEADED THIS WAY.  THE WAVE IS CAUSING QUITE A BIT OF PRECIP OVER
EASTERN NEBRASKA/KANSAS THIS MORNING...AND AM EXPECTING SOME OF THAT
PRECIP TO MAKE IT AS FAR AS CENTRAL/SOUTHEAST MISSOURI TODAY.
ADDITIONALLY..THE FRONT WHICH PASSED THROUGH OUR AREA A COUPLE OF
DAYS AGO WILL BEGIN DRIFTING BACK NORTH.  IT'S UNCLEAR HOW MUCH
CONVECTION THE INTERACTION OF THESE TWO FEATURES WILL CAUSE...BUT I
FEEL PRETTY CONFIDENT THERE WILL BE AT LEAST ISOLATED TO WIDELY
SCATTERED STORMS SOMEWHERE IN THE AREA THIS AFTERNOON.  IT'S EVEN
POSSIBLE THE MCS OVER NORTHEAST KANSAS WILL CONTINUE TRUCKING
EASTWARD THROUGH THE DAY AND MUCH OF THE AREA MAY NOT GET OUT OF THE
80S...BUT I THINK THIS IS NOT LIKELY.  REGARDLESS THERE WILL LIKELY
BE LOTS OF CONVECTIVE DEBRIS AROUND TODAY...SO HAVE LOWERED TEMPS A
SKOSH FROM PREVIOUS FORECAST.

THE LOW LEVEL JET RAMPS UP TONIGHT INTERSECTING THE MCV GENERATED BY
THIS MORNING'S CONVECTION AND BOTH THE GFS AND NAM KICK OUT SOME
SIGNIFICANT QPF IN RESPONSE.  OF COURSE THE GFS LOOKS WAY TO
ENTHUSIASTIC...BUT HAVE BUMPED UP POPS A BIT FOR TONIGHT SINCE THIS
SCENARIO LOOKS PLAUSIBLE.  WILL PASS TO THE DAY SHIFT TO PERHAPS
INCREASE POPS FURTHER AS HIGH-RES/SHORT-RANGE MODELS CAN HELP
PIN-POINT TIMING AND AREAL COVERAGE.

FRIDAY THROUGH SATURDAY CONTINUE TO BE CHALLENGING WITH CONVECTIVE
DEBRIS AND LEFT OVER CONVECTION FRIDAY MORNING POTENTIALLY MESSING
UP HIGHS FRIDAY AFTERNOON.  LOW LEVEL JET COULD GET NOCTURNAL
CONVECTION GOING AGAIN FRIDAY NIGHT/SATURDAY MORNING WHICH COULD
MESS UP TEMPERATURES AGAIN ON SATURDAY.  AS I MENTIONED
BEFORE...HIGH BUST POTENTIAL.  AT LEAST IT LOOKS LIKE THE AREA WILL
GET SOME MUCH-NEEDED RAIN OVER THE NEXT 3 DAYS.

CARNEY

&&

.LONG TERM...
ISSUED AT 352 AM CDT THU AUG 2 2012
(SATURDAY NIGHT THROUGH WEDNESDAY)

MODELS ARE STILL ADVERTISING A PROPER SYNOPTIC SCALE SHORTWAVE TO
MOVE EAST ALONG THE U.S. CANADA BORDER ON SATURDAY.  THE SURFACE
SYSTEM WILL PUSH A COLD FRONT DOWN THROUGH THE MISSISSIPPI VALLEY
WHICH SHOULD PASS THROUGH THE AREA SATURDAY NIGHT.  MODELS ARE IN
GOOD AGREEMENT ON THESE FEATURES...THO THERE IS STILL SOME
DISAGREEMENT ON HOW MUCH PRECIP WILL DEVELOP.  THE NAM AND GFS BOTH
PRINT OUT PRECIP OVER THE AREA WHILE THE ECMWF IS MUCH MORE STINGY.
AM SIDING WITH THE NCEP MODELS FOR NOW AS THIS IS A STRONG WAVE WITH
DECENT LOW LEVEL MOISTURE AND A GOOD LOW LEVEL CONVERGENCE ALONG THE
FRONT.  IF IT DOESN'T RAIN...IT'S GOING TO MISS AN AWFULLY GOOD
OPPORTUNITY TO DO SO.  COULD BE SOME LINGERING MORNING PRECIP ON
SUNDAY ON THE TAIL END OF THE FROPA ACROSS SOUTHEAST
MISSOURI...OTHERWISE SUNDAY WILL LIKELY BE DRY WITH MODERATING
TEMPERATURES.  REST OF THE FORECAST LOOKS DRY WITH SEASONABLE
TEMPERATURES ON MONDAY...BUT TUESDAY AND WEDNESDAY THE SURFACE HIGH
MOVES EAST INTO THE OHIO VALLEY.  THEREFORE TEMPERATURES LOOK TO
QUICKLY RISE BACK ABOVE AVERAGE INTO THE MID AND UPPER 90S TOWARD
MID-WEEK.
