AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1144 PM CDT MON JUN 18 2012

.UPDATE...
ISSUED AT 856 PM CDT MON JUN 18 2012

NO CHANGES TO THE FORECAST ARE NEEDED AS GOING LOW TEMPERATURES
STILL LOOK GOOD. CLEAR SKIES ARE EXPECTED THROUGH THE NIGHT.

.SHORT TERM...
ISSUED AT 255 PM CDT MON JUN 18 2012
(TONIGHT THROUGH WEDNESDAY)

TYPICAL EARLY-SUMMERTIME HEAT AND HUMIDITY EXPECTED THROUGH THE
SHORT TERM AS UPPER LEVEL RIDGE BUILDS OVER THE OHIO RIVER VALLEY.
ONLY SLIGHT VARIATIONS IN TEMPERATURE THE NEXT FEW DAYS AS 850MB
TEMPERATURES DROP A DEGREE OR TWO ON TUESDAY...ONLY TO RISE AGAIN ON
WEDNESDAY. SOUTH/SOUTHWEST BOUNDARY LAYER WIND WILL CONTINUE TO FEED
GULF MOISTURE NORTH.

.LONG TERM...
ISSUED AT 255 PM CDT MON JUN 18 2012
(WEDNESDAY NIGHT THROUGH MONDAY)

SHORTWAVE EXPECTED TO MOVE ACROSS THE NORTHERN PLAINS AND UPPER
MIDWEST WEDNESDAY NIGHT AND INTO THE GREAT LAKES REGION ON
THURSDAY. THIS SHOULD SEND A COLD FRONT SOUTH INTO THE REGION AS
THE MID/UPPER LEVEL FLOW WILL FLATTEN ACROSS THE CENTRAL CONUS.
UPPER LEVEL RIDGE IS FORECAST TO BUILD ACROSS THE PLAINS AND INTO
THE MIDWEST THROUGH THE REMAINDER OF THE FORECAST PERIOD WITH
NORTHWEST FLOW ACROSS THE UPPER MIDWEST/GREAT LAKES/OHIO RIVER
VALLEY IN RESPONSE TO A STRONG LOW SPINNING ACROSS THE HUDSON BAY.
THE CWA WILL RESIDE ON THE EASTERN PERIPHERY OF THE RIDGE ALOFT.

DETAILS...
COLD FRONT WILL SLOWLY SINK SOUTH INTO THE AREA LATE WEDNESDAY NIGHT
OR THURSDAY MORNING AND SERVE AS THE FOCUS FOR AT LEAST SCATTERED
THUNDERSTORM DEVELOPMENT THROUGH THURSDAY EVENING. HIGH BUST
POTENTIAL THURSDAY FOR TEMPERATURES AS OUTFLOW...CLOUDS AND
PRECIPITATION WILL DICTATE THE DIURNAL RISE IN TEMPERATURE.

I AM NOT ENTIRELY SURE THE FRONT WILL SINK SOUTH OF THE CWA. IT IS
GETTING TO BE THAT TIME OF THE YEAR WHEN FRONTS DON'T SEEM TO MOVE
AS FAR SOUTH AS THE MODELS WANT THEM TO. IT MAY BECOME STALLED FROM
NORTHWEST TO SOUTHEAST ACROSS MISSOURI THURSDAY NIGHT GIVEN THE
STRENGTH OF THE UPPER LEVEL RIDGE TO OUR SOUTHEAST. IF THIS
OCCURS...THE CHANCES OF THUNDERSTORMS WILL NEED TO BE EXTENDED INTO
FRIDAY MORNING AS NOCTURNAL CONVECTION WOULD LIKELY DEVELOP OVER NE
KANSAS/SE NEBRASKA AND PROPAGATE SOUTHEAST INTO THE CWA BY FRIDAY
MORNING.

SATURDAY THROUGH MONDAY...
MUCH OF THE EXTENDED FORECAST WILL DEPEND ON THE ORIENTATION AND
STRENGTH OF THE UPPER LEVEL RIDGE. IF IT BUILDS TOO FAR TO THE WEST
SUCH AS THE GFS ENSEMBLE MEAN SUGGESTS...WE WILL BE IN PRIME LOCATION FOR
CONVECTION THAT DEVELOPS ACROSS THE NORTHERN PLAINS AND UPPER
MIDWEST TO DROP SOUTH INTO OUR NECK OF THE WOODS. SO EVEN THOUGH THE
OFFICIAL EXTENDED FORECAST REMAINS DRY...I WOULDN'T BE SURPRISED IF
WE DON'T END UP WITH AT LEAST ONE EPISODE OF THUNDERSTORMS LATE NEXT
WEEKEND. MODELS CONTINUE TO HINT AT A COLD FRONT BRUSHING THE
EASTERN HALF OF THE CWA ON SUNDAY...BUT AGAIN THIS WILL ALL DEPEND
ON HOW FAR EAST THE RIDGE HAS INFLUENCE. OTHERWISE...TEMPERATURES
WILL REMAIN WELL ABOVE NORMAL GIVEN THE PROXIMITY OF THE UPPER
LEVEL RIDGE. IN FACT...TEMPERATURES COULD HIT 100 DEGREES ON
SATURDAY IF THE ECMWF 850MB TEMPERATURES VERIFY.
