AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1147 PM CST MON DEC 8 2008

...UPDATE TO AVIATION...

.DISCUSSION...

SHORT TERM  (TONIGHT THROUGH WEDNESDAY NIGHT)...

THE MAIN FORECAST FOCUS WILL BE OVER THE NEXT 36 HOURS OR SO AS A
STRONG STORM SYSTEM IMPACTS THE REGION. MANY THINGS TO CONSIDER
INCLUDING PRECIPITATION AMOUNTS AND TYPES...AS WELL AS
TEMPERATURES AND WINDS. MAY EVEN HAVE TO DEAL WITH A FEW
THUNDERSTORMS ON THE WARM SIDE OF THE STORM SYSTEM.

THE UPPER LEVEL PATTERN IS SOMEWHAT COMPLICATED AS THERE WILL BE A
HANDFUL OF INDIVIDUAL SHORT WAVE TROUGHS TO DEAL WITH AS THEY
ROUND THE BASE OF A MAIN LONG WAVE TROUGH. AT THE SURFACE...A
STRONG AREA OF LOW PRESSURE IS CURRENTLY DEEPENING ACROSS
SOUTHWEST KANSAS AND THE OKLAHOMA PANHANDLE. THE STRENGTH AND
TRACK OF THIS LOW WILL HAVE A DIRECT IMPACT ON OZARKS WEATHER.
THERE WILL ALSO BE SECONDARY AREAS OF LOW PRESSURE THAT DEVELOP IN
RESPONSE TO THOSE ADDITIONAL SHORT WAVE TROUGHS. THIS COMPLICATED
SCENARIO WILL PERSIST UNTIL THE AXIS OF THE MAIN LONG WAVE TROUGH
CROSSES THE AREA TUESDAY NIGHT.

LATE THIS AFTERNOON...WILL CONTINUE WIND ADVISORY OVER EXTREME
WESTERN MISSOURI AND SOUTHEAST KANSAS THROUGH 5 PM. JOPLIN HAS
ALREADY HIT CRITERIA AND SEE NO CHANGES IN SUSTAINED WINDS AND
GUSTS OVER THE NEXT COUPLE OF HOURS. WINDS WILL SLOWLY BEGIN TO
DIMINISH AROUND SUNSET.

TONIGHT...LARGE SCALE ASCENT WILL INCREASE WITH THE APPROACH OF
THE FIRST SHORT WAVE TROUGH. THE BEST LIFT WILL OVERSPREAD THE
AREA LATE TONIGHT...ESPECIALLY OUT WEST WITH THE APPROACH OF THAT
SURFACE LOW AND A STRONG COLD FRONT. WENT WITH CATEGORICAL POPS
AREAWIDE. THINK ENOUGH INSTABILITY WILL BE AROUND TO CARRY A
SLIGHT CHANCE FOR THUNDER. TEMPERATURES WILL STRUGGLE TO FALL
TONIGHT AS STRONG SOUTHERLY WINDS CONTINUE TO ADVECT MOISTURE
NORTHWARD.

TUESDAY...THAT FIRST SURFACE LOW WILL PULL NORTHEAST INTO THE
SOUTHERN GREAT LAKES. A STRONG COLD FRONT WILL QUICKLY SHIFT
SOUTHEAST THROUGH THE AREA BEHIND THE LOW. THE BEST PRECIPITATION
CHANCES WILL LIKELY COME IN THE MORNING OVER CENTRAL MISSOURI AS
A DRY SLOT MAY TEND TO SHUT THE ORGANIZED PRECIPITATION DOWN LATER
IN THE DAY. STRONG COLD ADVECTION WILL LEAD TO A FAIRLY RAPID
CHANGE OVER FROM LIQUID TO FROZEN PRECIPITATION. NOT OUT OF THE
QUESTION WE COULD SEE A BRIEF PERIOD OF FREEZING RAIN OR
SLEET...BUT THE PREDOMINANT FROZEN PRECIPITATION TYPE WILL BE
SNOW. LITTLE IF ANY ACCUMULATION IS EXPECTED ON TUESDAY...EXCEPT
PERHAPS FOR AREAS OF WEST CENTRAL AND CENTRAL MISSOURI. THOSE
AREAS MAY SEE A BURST OF SNOW AS MOISTURE WRAPS AROUND THAT
DEPARTING LOW. WILL NEED TO WATCH WINDS CLOSELY AS WE MAY APPROACH
ADVISORY CRITERIA ONCE AGAIN OVER SOME AREAS.

TUESDAY NIGHT...ANOTHER SHORT WAVE TROUGH WILL APPROACH FROM THE
SOUTHWEST AS THE MAIN TROUGH AXIS SETTLES SOUTHEAST. MEANWHILE...A
WEAK SURFACE WAVE/LOW WILL LIKELY DEVELOP AND SWING NORTHEAST
ALONG THE FRONT IN ARKANSAS. AM NOT EXPECTING A LOT OF
PRECIPITATION...BUT IT IS A TOUGH CALL WITH RESPECT TO
PRECIPITATION TYPE. THE MAIN QUESTION FOR THIS PERIOD WILL BE
CLOUD ICE. WOULD EXPECT SOME MID LEVEL SATURATION (BEHIND THE DRY
SLOT) WITH THE APPROACH OF THE WAVE AND TROUGH AXIS. IT MAY BE
ENOUGH FOR CLOUD ICE...OR PERHAPS THE SEEDER/FEEDER EFFECT. WILL
THEREFORE CARRY SLIGHT CHANCE/LOW END CHANCE POPS FOR LIGHT SNOW.
WE COULD SEE ADDITIONAL MINOR ACCUMULATIONS OF SNOW IF WE CAN GET
THE CLOUD ICE. OTHERWISE...THINK THE MORE PREVAILING PRECIPITATION
TYPE MAY BE FREEZING DRIZZLE. WILL NEED TO WATCH THIS CLOSELY.
BRISK NORTHERLY WINDS AND PLUMMETING TEMPERATURES WILL MAKE FOR A
DOWNRIGHT RAW NIGHT.

WEDNESDAY AND WEDNESDAY NIGHT...THIS SYSTEM WILL FINALLY PULL EAST
OF THE AREA WITH SKIES CLEARING. TEMPERATURES WILL BE TRICKY AS A
SURFACE RIDGE AXIS SETTLES OVER THE REGION. WENT COOLER THAN ALL
FORMS OF MOS GUIDANCE...ESPECIALLY WEDNESDAY NIGHT WITH THE RIDGE
AXIS NEARLY OVERHEAD.

SCHAUMANN

LONG TERM (THURSDAY THROUGH MONDAY)...

AN UPPER LEVEL SHORTWAVE TROUGH WILL QUICKLY PUSH THROUGH THE
REGION LATE IN THE WEEK BRINGING A REINFORCING SHOT OF COOLER AIR
TO THE REGION. THIS DISTURBANCE WILL ALSO BRING A CHANCE OF LIGHT
SNOW AND OR LIGHT RAIN TO THE NORTHERN CWA ON FRIDAY. THERE WILL
BE LIMITED MOISTURE AVAILABLE TO THE REGION WHEN THIS DISTURBANCE
PUSHES THROUGH...SO NOT MUCH MORE THAN FLURRIES OR SPRINKLES WILL
BE POSSIBLE IF ANY PRECIPITATION IS ABLE TO DEVELOP. HAVE ADDED
SLIGHT CHANCE POPS TO THE FORECAST ON FRIDAY ACROSS THE NORTHERN
CWA.

WARMER TEMPERATURES WILL RETURN TO THE AREA THIS WEEKEND AS THE
SHORTWAVE TROUGH PUSHES OFF TO THE EAST AND UPPER LEVEL RIDGING
BUILDS INTO THE AREA. AN UPPER LEVEL LOW WILL DEVELOP ACROSS THE
NORTHWESTERN CONUS THIS WEEKEND AND WILL DIG SOUTH INTO THE
SOUTHWESTERN CONUS BY THE START OF NEXT WEEK. THIS WILL HELP PUMP
MOISTURE INTO THE REGION AND RETURN CHANCES FOR PRECIPITATION TO
THE AREA SUNDAY INTO THE WORK WEEK...AS ENERGY FROM THIS LOW
EJECTS NORTHEAST INTO THE REGION. A COLD FRONT WILL ALSO PUSH
SOUTH TOWARDS THE AREA EARLY NEXT WEEK AND WILL ALSO BE A FOCUS
FOR PRECIPITATION. TEMPERATURES SOUTH OF THE FRONT WILL REMAIN
WARM ENOUGH TO KEEP THE PRECIPITATION IN THE FORM OF RAIN...AND
WITH COLDER AIR BEHIND THE FRONT...WINTRY PRECIPITATION WILL BE
POSSIBLE. AT THIS TIME IT APPEARS THE FRONT WILL REMAIN FAR ENOUGH
NORTH TO KEEP THE PRECIPITATION IN THE FORM OF RAIN FOR THE ENTIRE
CWA. WILL HAVE TO KEEP AN EYE ON THIS FRONT. IF IT SETS UP FARTHER
SOUTH...PORTIONS OF THE CWA COULD SEE WINTRY PRECIPITATION.

.AVIATION...

FOR THE 0600 UTC KSGF/KJLN TAFS...SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS HAVE MOVED INTO THE REGION LATE THIS EVENING AS LOW
LEVEL MOISTURE INCREASES AND LIFT BECOMES ENHANCED WITH A STRONG UPPER
LEVEL DISTURBANCE MOVING NORTHEAST THROUGH OK.
SHOWERS/THUNDERSTORMS WILL BECOME MORE NUMEROUS OVERNIGHT...BUT
KEPT CEILINGS IN THE MVFR CATEGORY FOR THE MOST PART UNTIL A
STRONG COLD FRONT SWEEPS THROUGH THE REGION EARLY TUE MORNING.
CEILINGS SHOULD GENERALLY BE IFR BEHIND THE FRONT ALONG WITH THE
POTENTIAL FOR LOWER VISIBILITY WITH LIGHT RAIN AND DRIZZLE. LIGHT
PRECIPITATION SHOULD GRADUALLY SWITCH OVER TO SNOW IN THE
AFTERNOON...AND SOME POTENTIAL EXISTS FOR LOWER VISIBILITY IN
LIGHT SNOW INTO THE EARLY EVENING HOURS. DRYER AIR LOOKS LIKE IT
WILL START TO WORK ITS WAY INTO THE REGION TUE EVENING WITH SOME
IMPROVEMENT IN CEILINGS BACK UP INTO THE MVFR CATEGORY. DSA
