AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
603 AM CDT FRI MAY 13 2011

...UPDATE TO AVIATION...

.DISCUSSION...

THE UPPER LEVEL LOW THAT HAS BEEN THE DRIVING FORCE BEHIND THE
WEATHER OVER THE PAST 24 HOURS...CONTINUES TO SPIN OVER CENTRAL
KANSAS THIS MORNING. THUNDERSTORMS THAT BROUGHT LARGE HAIL TO THE
REGION WERE ALSO PUSHING EAST OF THE MISSISSIPPI RIVER.

RESIDUAL MOISTURE FROM STORMS LAST NIGHT...COMBINING WITH COOLING
TEMPERATURES WILL RESULT IN THE DEVELOPMENT OF FOG ACROSS PORTIONS
OF THE OZARKS THIS MORNING. SOME AREAS MAY SEE VISIBILITIES FALL
TO BELOW A MILE AT TIMES.

THE UPPER LEVEL LOW WILL MOVE OVER THE REGION DURING THE DAY
TODAY. THIS WILL BRING THE CHANCE FOR CONTINUED SHOWERS AND
THUNDERSTORMS INTO THE AFTERNOON AND EARLY THIS EVENING. FORECAST
SOUNDINGS DO INDICATE SOME GOOD CAPE AVAILABLE THIS AFTERNOON AS
THE UPPER LOW MOVES OVERHEAD. CAPE VALUES ON GFSBUFR SOUNDINGS
SHOW FROM 1000 TO 1500 J/KG PRIMARILY ALONG AND EAST OF HIGHWAY 65
FROM 18Z THROUGH 00Z. THIS IS SUPPORTED SOMEWHAT BY THE NAM AND
GFS WHICH DO SHOW CAPE VALUES UP TO 1000 J/KG. GOOD MID LEVEL
LAPSE RATES...LIFTED INDICES FROM -2 TO -6 AND LOWERING FREEZING
LEVELS UNDER THE COLD CORE OF THE UPPER LOW WOULD INDICATE THE
CHANCE FOR SOME STRONG TO ISOLATED SEVERE THUNDERSTORMS THIS
AFTERNOON THOUGH SHEAR WILL BE LIMITED AT BEST. THINK THE MAIN
THREAT WITH THE STORMS THAT DEVELOP WILL BE HAIL...THOUGH NOT AS
LARGE AS WHAT OCCURRED LAST NIGHT.

THE UPPER LOW WILL CONTINUE TO TRANSLATE TO THE EAST THROUGH THE
WEEKEND AS A SECOND UPPER LEVEL LOW DIVES OUT OF CANADA AND
PINWHEELS AROUND THE FIRST LOW. THE TWO LOWS WILL THEN PHASE
TOGETHER OVER EASTERN MISSOURI AND PROVIDE ADDITIONAL CHANCES FOR
SHOWERS LATE SUNDAY INTO MONDAY.

AS A RESULT OF THE GENERAL NORTHWESTERLY FLOW PATTERN THAT
DEVELOPS TODAY AND REMAINS IN PLACE THROUGH MUCH OF NEXT
WEEK...TEMPERATURES WILL BE UNSEASONABLE COOL. WITH 850
MB TEMPERATURES FALLING AS LOW AS 1 TO 2 DEGREES C AT TIMES
DURING THE WEEKEND...SOME LOCATIONS MAY NOT SEE HIGHS CLIMB OUT OF
THE 50S. FOR NEXT WEEK...HIGHS SHOULD BE IN THE 60S THROUGH MOST
OF THE WEEK WITH LOWS IN THE 40S THROUGH THE FORECAST PERIOD.

THE NEXT BEST CHANCE FOR RAINFALL AND STORMS WOULD BE LATE NEXT
WEEK AS ANOTHER UPPER LEVEL LOW CUTS OFF AND MAKES AN ATTEMPT TO
UNDER CUT THE RIDGE ACROSS THE CENTER OF THE COUNTRY. WILL NEED TO
WATCH THIS AND SEE IF THIS LOW WILL BE STRONG ENOUGH TO BREAK THE
BLOCKING PATTER NOW SETTING UP OVER THE CONUS.

HATCH

.AVIATION...

FOG HAS REDUCED VISIBILITIES ACROSS PORTIONS OF SOUTHWEST MISSOURI
EARLY THIS MORNING. HAVE GONE WITH PRIMARILY LOW END VFR IN THE
TAFS...BUT THERE ARE POCKETS OF MVFR AND EVEN BRIEF IFR SCATTERED
ABOUT. ANY REDUCTIONS TO VISIBILITY WILL IMPROVE BY MID MORNING AS
WINDS INCREASE OUT OF THE WEST. SHOWERS AND A FEW THUNDERSTORMS
ARE THEN EXPECTED TO DEVELOP THIS AFTERNOON...WITH THE BEST
CHANCES FOR THUNDERSTORMS AT KSGF AND KBBG. CEILINGS WILL LOWER
WITH MVFR BECOMING PREVAILING. THE MVFR CEILINGS WILL THEN
CONTINUE INTO TONIGHT AT KSGF AND KBBG. KJLN APPEARS THAT IT WILL
BE RIGHT ON THE EDGE BETWEEN SCATTERED AND BROKEN CLOUD COVER.
