AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
423 AM CDT MON APR 20 2009

.DISCUSSION...
/335 AM CDT MON APR 20 2009/
SURFACE LOW OVER CENTRAL INDIANA AS OF 08Z WILL CONTINUE TO LIFT TO
THE NORTH NORTHEAST INTO THE GREAT LAKES REGION...WHERE IT BECOMES
VERTICALLY STACKED WITH UPPER SYSTEM AND STALLS OUT FOR THE NEXT
COUPLE OF DAYS. SO MAIN FORECAST ISSUE IN THE SHORT TERM WILL BE
DEALING WITH SHORTWAVES AS THEY ROTATE AROUND THE SYSTEM THROUGH
TUESDAY.

FOR TODAY...INITIALLY SEE MOSTLY CLEAR SKIES ACROSS MAJORITY OF
CWA...BUT BY MID MORNING EXPECT DIURNAL CU TO POP UP...ESPECIALLY
FOR AREAS ALONG AND EAST OF MS RIVER. IN THE MEANTIME...MODELS
SHOWING FIRST IN A SERIES OF SHORTWAVES SLIDING THROUGH AREA BY 18Z.
THE LIFT IN CONJUNCTION WITH STEEP LAPSE RATES WILL GENERATE SHOWER
ACTIVITY AS WELL AS SOME LOW-TOPPED THUNDERSTORMS THIS AFTERNOON. SO
UPPED POPS AND ADDED ISOLATED THUNDERSTORM MENTION TO GRIDS. SPC HAS
PLACED AREAS EAST OF MS IN A SEE TEXT AS WE COULD SEE SOME SMALL
HAIL AND GUSTY WINDS WITH SOME OF THE STORMS. ANOTHER ISSUE FOR
TODAY WILL BE THE WINDS. WITH SUCH STRONG MIXING EXPECTED ...COULD
SEE 40+ KT WINDS MAKING THEIR WAY DOWN TO THE SURFACE. HOWEVER...IF
CLOUDS BUILD UP ENOUGH...THIS COULD HINDER THE MIXING SOMEWHAT...SO
JUST BUMPED UP GUSTS TO 35 KTS...BELOW WIND ADVISORY CRITERIA. DAY
CREW WILL NEED TO KEEP AN EYE ON THIS. AS FOR TEMPS...WITH NORTHWEST
FLOW...CLOUDS AND A FEW SHOWERS...EXPECT HIGHS ONLY IN THE UPPER 50S
TO LOWER 60S.

EXPECT SOME LINGERING SHOWER ACTIVITY EARLY THIS EVENING AS THE
GUSTY WINDS DIMINISH. OTHERWISE...BELOW NORMAL TEMPS CAN BE EXPECTED
WITH LOWS IN THE UPPER 30S TO LOWER 40S.

ON TUESDAY...WE REMAIN IN CYCLONIC FLOW WITH ADDITIONAL SHORTWAVES
SLIDING THROUGH REGION. SHOWER ACTIVITY WILL BE FURTHER EAST
THOUGH...SO JUST HAVE CHANCE POPS IN THE AFTERNOON IN OUR FAR
EASTERN COUNTIES. ANOTHER BELOW NORMAL DAY WITH TEMPS IN THE UPPER
50S TO LOWER 60S.

ONE LAST CHILLY NIGHT TUESDAY NIGHT WITH LOWS IN THE UPPER 30S TO
LOWER 40S...THEN THE WARMUP KICKS IN FOR THE LAST HALF OF THE WORK
WEEK AND INTO THIS WEEKEND. HIGHS WEDNESDAY WILL BE IN THE MID 60S
TO LOWER 70S...IN THE MID TO UPPER 70S THURSDAY AND IN THE UPPER 70S
TO LOWER 80S FOR THE REST OF THE FORECAST PERIOD. EXTENDED GRIDS IN
GOOD SHAPE SO NO MAJOR CHANGES.

.AVIATION...
/421 AM CDT MON APR 20 2009/
FOR THE 12Z TAFS...

POTENT UPPER LEVEL DISTURBANCE EVIDENT ON WATER VAPOR IMAGERY
ACROSS MINNESOTA WILL DIVE SOUTHEAST ACROSS IOWA THIS MORNING AND
INTO WESTERN ILLINOIS THIS AFTERNOON. MID DECK OF CLOUDS ACROSS
SOUTH DAKOTA AND NEBRASKA EXPECTED TO MOVE ACROSS KCOU THIS
MORNING...WITH ONLY SCT MID CLOUDS AT REMAINING TERMINALS. STEEP
LOW LEVEL LAPSE RATES DUE TO THE COMBINATION OF STRONG APRIL
SUNSHINE AND UNSEASONABLY COLD AIR ALOFT WILL CREATE ENOUGH
INSTABILITY FOR CONVECTION TO INITIATE BY THIS AFTERNOON AHEAD OF
THE AFOREMENTIONED VORTICITY MAXIMA. GIVEN CURRENT TRACK OF THE
DISTURBANCE...BELIEVE THE BEST PROBABILITY OF PRECIPITATION WILL
BE EAST OF THE TERMINALS ACROSS CENTRAL AND SOUTHWEST ILLINOIS.

MODEL SOUNDINGS CONTINUE TO INDICATE POTENTIAL FOR EXCELLENT MIXING
TODAY...WITH BUFKIT TOOL KIT INDICATING MIX DOWN POTENTIAL OF
35-40KT. FOR NOW HAVE PLAYED THE WIND SPEED CONSERVATIVELY IN TAFS
AS MOS GUIDANCE ONLY INDICATES NORTHWEST WIND OF 20-25KT SUSTAINED
WITH 30KT GUSTS.

CONVECTION EXPECTED TO DISSIPATE AND WIND SPEED TO DECREASE THIS
EVENING WITH LOSS OF DIURNAL INSTABILITY AND MIXING.
