AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
314 PM CDT THU MAR 15 2012

.DISCUSSION...
/ISSUED 255 PM CDT THU MAR 15 2012/

CURRENTLY...WEAK SHORTWAVE IN THE MID LEVELS IS SLIDING INTO THE
AREA. SCATTERED THUNDERSTORMS HAVE DEVELOPED ACROSS THE EASTERN
OZARKS...EAST OF THE HIGHWAY 65 CORRIDOR. WHILE INSTABILITY IS
MODEST...SHEAR IS WEAK. AS A RESULT A FEW HAILERS CAN BE EXPECTED
WITH A RISK FOR A FEW STORMS TO PRODUCE QUARTER SIZED HAIL.
LOCALIZED WIND DAMAGE IS POSSIBLE...BUT SHOULD BE THE EXCEPTION
RATHER THAN THE RULE.

TODAY THROUGH SUNDAY...MORE OF THE SAME WEATHER WISE AS OUR
WEATHER PATTERN CHANGES VERY LITTLE. HAVE KEPT CHANCE POPS OVER
THE EASTERN OZARKS THIS EVENING AS ACTIVITY THAT HAS DEVELOPED
OVER THE EASTERN OZARKS THIS AFTERNOON WANES IN COVERAGE/INTENSITY
AND EXITS TO THE EAST. ANOTHER WARM EVENING IS EXPECTED WITH LOWS
IN THE UPPER 50S/LOWER 60S. WILL NEED TO MONITOR FOR POSSIBLE
PATCHY FOG DEVELOPMENT ACROSS SOUTH CENTRAL MISSOURI OVERNIGHT...
WHERE RAINFALL HAS BEEN MORE PREVALENT TODAY. FRIDAY WILL BE
WARM...AKIN TO WEDNESDAY/S WEATHER. TEMPERATURES WILL PEAK NEAR 80
DEGREES AGAIN IN MOST LOCATIONS WITH ISOLATED SHOWERS AND STORMS
POSSIBLE DURING THE AFTERNOON. INDICATIONS ARE THAT THERE WILL BE
A LACK OF UPPER SUPPORT...SO IF ACTIVITY DOES DEVELOP IT WILL BE
ISOLATED AND LIKELY SHORT LIVED.

ANOTHER WEAK SHORTWAVE IS PROGGED TO MOVE INTO THE REGION LATE
FRIDAY NIGHT INTO SATURDAY. AS A RESULT SATURDAY WILL LIKELY BE
MUCH LIKE TODAY...BUT WITH EXPECTATIONS FOR SCATTERED SHOWER AND
THUNDERSTORMS ACTIVITY AFFECTING THE ENTIRE AREA. THIS WILL LIKELY
SHAVE A FEW DEGREES OFF OF TEMPERATURES...BUT READINGS WELL INTO
THE 70S CAN BE EXPECTED AGAIN. THE WEAK DISTURBANCE WILL EXIT TO
THE EAST SATURDAY NIGHT...WITH MAINLY QUIET CONDITIONS EXPECTED
SUNDAY AND SUNDAY NIGHT. TEMPERATURES WILL ONCE AGAIN PEAK AROUND
80 ON SUNDAY WITH LOWS SATURDAY AND SUNDAY NIGHTS NEAR PERSISTENCE
WITH VALUES IN THE UPPER 50S AND LOWER 60S.

MONDAY THROUGH THURSDAY...12Z SUITE OF MODEL OUTPUT OFFERS LITTLE
CHANGE TO THE GOING FORECAST. AMPLIFIED PATTERN WILL SET UP OVER
NORTH AMERICA WITH A STRONG TROUGH SLOWLY APPROACHING FROM THE
WEST DURING THE EARLY HALF OF NEXT WEEK. BIGGEST CHALLENGES TO THE
FORECAST WILL BE POPS/TEMPS. SHOULD STILL OBSERVE WELL ABOVE
AVERAGE TEMPERATURES (ESPECIALLY LOWS GIVEN A CONTINUED MOIST
ATMOSPHERE)...HIGHS HOWEVER MAY NOT BE AS WARM AS WE OBSERVED THIS
PAST WEEK (THOUGH STILL IN THE 70S FOR MOST LOCATIONS). HAVE
CONTINUED HIGH CHANCE AND INTRODUCED AREAS OF LIKELY POPS MONDAY
AND TUESDAY AS CONFIDENCE IN RAINFALL HAS INCREASED. BIGGEST
QUESTION FOR WEDNESDAY AND THURSDAY IS WHERE THE UPPER LEVEL
CUTOFF LOW SETS UP. CURRENT INDICATIONS FROM THE GFS/ECMWF IS THAT
THIS FEATURE WILL BE CLOSE BY...THUS THERE IS CONSIDERABLE
UNCERTAINTY WITH TEMPERATURES DURING THIS TIME FRAME. HAVE KEPT
POPS IN THE HIGH CHANCE RANGE GIVEN CONTINUED SUPPORT FOR LARGE
SCALE LIFT AND AMPLE MOISTURE.

.AVIATION...

FOR THE 18Z TAFS...

MVFR CIGS AND OCCASIONAL TSRA CAN BE EXPECTED DURING THE AFTERNOON
HOURS AT THE TERMINALS. HAVE ONLY INDICATED CB GROUP FOR NOW...AS
TIMING/COVERAGE OF TSRA IS TOO LOW TO JUSTIFY INCLUSION OF
PREVAILING GROUP ATTM.

TSRA CHANCES WILL BE LARGELY DIURNALLY DRIVEN...AND THUS EXPECT
RAPID DECREASE AFTER SUNSET OF ANY CONVECTION. ONLY CONCERN
OVERNIGHT WILL BE MARGINAL LLWS AT JLN AND BBG.
