AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE CHICAGO IL
245 PM CDT TUE APR 3 2007

.DISCUSSION FOR AFTERNOON ZONES/GRIDS...
245 PM CDT

MAIN FORECAST CONCERN WILL BE ON FRONTAL PASSAGE THIS EVENING AND
SHOWER/THUNDERSTORM POTENTIAL LATE THIS AFTERNOON/EARLY THIS
EVENING. SURFACE COLD FRONT AFTER 19Z EXTENDS FROM NORTH CENTRAL
ILLINOIS THROUGH WEST CENTRAL ILLINOIS AND INTO SOUTHEAST MISSOURI.
PRIMARY INSTABILITY AXIS OF MUCAPE FROM 1000-2000 J/KG EXTENDS FROM
SOUTHERN ILLINOIS THROUGH EXTREME SOUTHEASTERN PORTIONS OF THE
FORECAST AREA. ALTHOUGH DECENT LOW LEVEL MOISTURE ADVECTION HAS BEEN
OCCURRING THROUGH THE DAY...ABUNDANT CLOUD COVER FROM MORNING
CONVECTION AND ONGOING THUNDERSTORMS TO THE SOUTH HAVE LIMITED
POTENTIAL FOR DEEP MOIST CONVECTION ACROSS THE LOT CWA THIS
AFTERNOON. WILL CONTINUE TO CARRY SCT TSRA MENTION SOUTH OF I-80
THIS EVENING AS SHORT WAVE ACROSS WESTERN MISSOURI RACES ACROSS
CENTRAL/SOUTHERN ILLINOIS. SEVERE THREAT APPEARS TO BE VERY LIMITED
FOR THE REMAINDER OF THE AFTERNOON...AND CONFINED TO FAR SOUTHEAST
PORTIONS OF THE FORECAST AREA THROUGH ABOUT 00Z.

OF PERHAPS MORE CONCERN WILL BE WIND POTENTIAL TONIGHT INTO
WEDNESDAY. STRONGEST PRESSURE RISES BEHIND THE SURFACE FRONT ARE
TRACKING INTO EASTERN KANSAS/MISSOURI AT THIS TIME...BUT FURTHER
NORTH ACROSS IOWA/SOUTHERN MINNESOTA SFC WINDS OF 25G35KT ARE FAIRLY
WIDESPREAD. SFC LOW ACROSS NORTHERN ILLINOIS WILL CONTINUE TO DEEPEN
TONIGHT...DRAWING COLDER AIR FROM THE NORTHERN PLAINS SOUTHEASTWARD.
EXPECTING WINDS TO BRUSH UP AGAINST ADVISORY CRITERIA THIS EVENING
BEHIND THE FRONT. SPEEDS MAY THEN SUBSIDE VERY LATE TONIGHT BUT DEEP
MIXED LAYER TOMORROW WITH STRONG CAA SHOULD ALLOW WINDS TO APPROACH
ADVISORY CRITERIA AGAIN DURING THE DAY TOMORROW. WILL ISSUE A WIND
ADVISORY FOR TONIGHT MAINLY FOR AREAS ALONG AND NORTH OF I-80. MAY
NEED TO EXTEND THIS ADVISORY FURTHER SOUTH...BUT WITH STRONGEST LOW
LEVEL HEIGHT GRADIENT/DEEPEST MIXED LAYER ACROSS NORTHERN AREAS FEEL
THAT BEST CHANCE OF MEETING WIND ADV CRITERIA WILL BE ACROSS
NORTHERN HALF OF THE CWA. DID MAINTAIN MENTION OF FLURRIES OVERNIGHT
WITH STRONG COLD ADVECTION RINGING OUT ANY LINGERING LOW LEVEL
MOISTURE.

DID TWEAK TEMPS DOWN JUST A SHADE FOR TOMORROW WITH FORECAST
SOUNDINGS INDICATING MIXED LAYER DEPTHS UP TO ABOUT 850 HPA. NAM 850
HPA TEMPS TOMORROW AFTERNOON RANGE FROM -11 DEG CELS NORTH TO -9 DEG
CELS SOUTH. GIVEN THESE LOW LEVEL TEMPS...HIGHS FROM MID TO UPPER
30S SEEM REASONABLE. LITTLE CHANGE MADE TO THE REMAINDER OF THE
FORECAST WITH EXTENDED PERIOD OF MUCH BELOW NORMAL TEMPERATURES AS
POLAR LOW DROPS SOUTHWARD AND GETS INGESTED INTO THE EASTERN CONUS
UPPER LOW TOWARD THE END OF THE WEEK. ANY LAKE EFFECT SNOW SHOWERS
SHOULD AFFECT MAINLY PORTER COUNTY IN NWRN INDIANA GIVEN NWRLY FLOW
TRAJECTORIES...BUT NOT EXPECTING ANY SIGNIFICANT ACCUMULATIONS.

SOME MODERATION IN TEMPS EXPECTED BY EARLY NEXT WEEK AS UPPER FLOW
BEGINS TO FLATTEN. HOWEVER THIS SHOULD RESULT IN ANOTHER ACTIVE
SHORT WAVE PATTERN WITH RETURN WAA/ISENTROPIC LIFT. DID INTRODUCE
CHANCE POPS FOR RAIN SHOWERS TOWARD THE END OF THE PERIOD TO ACCOUNT
FOR THIS.

MARSILI

&&

.AVIATION DISCUSSION FOR 18Z TAFS...
1245 PM CDT

SEVERAL CONCERNS FOR THE LATEST TAF SET.  THE FIRST WILL BE TT
POTENTIAL FOR THE REMAINDER OF THE AFTERNOON HOURS.  THE MORNING
THUNDER HAS LEFT SIGNIFICANT CLOUD COVER BEHIND AND STABILIZED THE
LOWER LEVELS.  FEEL THAT THUNDER POTENTIAL STILL
EXISTS...PARTICULARLY AS THE STRONG COLD FRONT SWEEPS ACROSS THE
REGION THIS AFTERNOON...BUT HAVE BACKED OFF FROM PREVAILING TO A
TEMPO GROUP.  BEST CHANCE FOR THUNDER WILL BE ALONG THE FRONTAL
BOUNDARY INVOF THE BEST FORCING.  THE FOCUS WILL THEN SHIFT TO
WINDS.  BETWEEN A TIGHTENING PRESSURE GRADIENT BEHIND A SURFACE LOW
WHICH WILL CROSS NRN IL/IN LATE AFTERNOON-EARLY EVENING...AND HIGH
PRESSURE BUILDING DOWN THE NRN PLAINS...PLUS STRONG COLD ADVECTION
BEHIND THE COLD FRONT...WINDS SILL BECOME STRONG AND GUSTY.  WITH
THE FRONTAL PASSAGE AND WINDS SHIFT...WINDS WILL INCREASE TO ARND
25KT WITH FREQUENT GUSTS TO ARND 30KT.  WHILE THUNDER WILL GENERALLY
BE SHORT IN DURATION...SHOULD BE A TRAILING AREA OF -SHRA BEHIND THE
FRONT.  AS THE COLDER AIR FILTERS OVER THE REGION...CEILINGS ARE
EXPECTED TO LOWER TO MVFR LEVELS. LATEST MODEL RH PROFILES ARE
SUGGESTING THAT THE MOISTURE WILL BE CONFINED TO LAYERS BELOW
10KFT...SUGGESTING MORE OF FLURRY OR LIGHT SHSN SCENARIO.  UPPER
FORCING WILL NOT BE TOO STRONG...SO ANY REDUCTIONS TO VSBY WILL BE
ONLY ENUF TO JUSTIFY A TEMPO MVFR GROUP.
