AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
853 PM CDT MON MAY 25 2009

.DISCUSSION...
ISSUED 853 PM CDT MON MAY 25 2009

PRECIPITATION COVERAGE HAS DIMINISHED ACROSS AND UPSTREAM FROM THE
FORECAST AREA EARLY THIS EVENING. THIS DIMINISHING TREND HAS
LARGELY BEEN DRIVEN BY THE LOSS OF DIURNAL HEATING. VERTICALLY
STACKED LOW IS CURRENTLY CENTERED OVER SOUTHWEST MISSOURI...WITH A
WARM FRONT EXTENDING EAST INTO THE OHIO VALLEY. THE BULK OF THE
LINGERING PRECIPITATION IS IN THE VICINITY OF THIS BOUNDARY AND
THIS TREND SHOULD CONTINUE FOR THE MOST PART. THERE ALSO SHOULD BE
SOME ENHANCED PRECIPITATION DEVELOPMENT OVER EASTERN MISSOURI
WHERE A MODEST LOW LEVEL JET IS EXPECTED OVERNIGHT. THE UPSHOT OF
THIS IS THAT THE MEASURABLE PRECIPITATION THREAT HAS DIMINISHED
FOR THE NIGHT ACROSS MOST OF THE FORECAST AREA OUTSIDE OF
SOUTHEAST ILLINOIS.

PLAN ON UPDATING FORECAST FOR THE LATEST TRENDS. MOST OF THE
ADJUSTMENTS WILL BE MINOR...BUT PLAN ON LOWERING POPS INTO THE
CHANCE/SCATTERED CATEGORY IN THE NORTH.

BAK
&&

.AVIATION...
ISSUED 711 PM CDT MON MAY 25 2009

SHOWER/STORM BANDS TO THE NORTH/EAST OF SLOW MOVING AREA OF LOW
PRESSURE CENTERED OVER SOUTHWEST MISSOURI HAVE STARTED TO DIMINISH
WITH THE LOSS OF DIURNAL HEATING. SOME ADDITIONAL PRECIPITATION
DEVELOPMENT REMAINS POSSIBLE TONIGHT...THOUGH THE BULK OF IT WILL
REMAIN CLOSER TO THE SURFACE LOW THROUGH THE NIGHT. EXPECT THE
PRECIPITATION COVERAGE TO INCREASE AGAIN TUESDAY WITH DIURNAL
HEATING...BUT CONFIDENCE IN THE TIMING/LOCATION OF THIS
PRECIPITATION IS TOO LOW TO GO ABOVE A VICINITY MENTION IN THE
TAFS AT THIS TIME. ASIDE FROM THE PRECIPITATION...EXPECT CIGS TO
FALL THROUGH THE MVFR CATEGORY THIS EVENING...WITH SEVERAL HOURS
OF IFR CONDITIONS POSSIBLE LATER TONIGHT. CIGS SHOULD RISE BACK
INTO THE MVFR CATEGORY AS TEMPERATURES WARM ON TUESDAY. EASTERLY
WINDS WILL BEGIN TO TREND SOUTHEAST WITH TIME AS THE SURFACE LOW
TRACKS TO OUR WEST ON TUESDAY.

BAK

.PREV DISCUSSION...
ISSUED 145 PM CDT MON MAY 25 2009

WEAK FRONTAL BOUNDARY DRAPED ACRS THE I-70 CORRIDOR SEEMS TO BE
THE FOCUS...AT LEAST SHORT TERM...FOR CONVECTION TO DEVELOP AND
SPREAD NWD. INTENSE RAINFALL RATES ASSOCIATED WITH SOME OF THE
MORE INTENSE CELLS WITH A REPORT FROM ROBINSON IN CRAWFORD CO.
OF OVER 3 INCHES OF RAIN SO FAR (SINCE EARLIER THIS MRNG). HAVE
SEEN SOME BROAD SCALE ROTATION WITH SOME OF THE CELLS NEAR THE
BNDRY BUT INSTABILITY IS MEAGER AT BEST AT THIS TIME. HOWEVER...
0-1KM SRH VALUES ACRS THE SE...NEAR THE BNDRY...WERE RANGING
FROM 75-150 M2/S2. MODELS INDICATE JUST ENOUGH LOW LEVEL DIR
SHEAR WHICH WILL PRODUCE AN ENHANCED THREAT FOR ISOLATED STORMS
TO EXHIBIT LOW LEVEL ROTATION FOR A BRIEF TIME INTO EARLY THIS
EVENING.

SHORT TERM...TONIGHT THROUGH THURSDAY

LITTLE OVERALL CHANGE FROM PREVIOUS THINKING...THE MAIN FORECAST
CHALLENGE WILL BE MOVEMENT OF WEAKENING UPPER LEVEL DISTURBANCE
OVER EXTREME SW MO OVR THE NEXT SEVERAL DAYS AND AREAL EXTENT OF
HEAVY RAIN THREAT ACRS CNTRL IL.

WATER VAPOR LOOP AND PROFILER DATA INDICATING UPPER LEVEL STORM
TRACKING VERY SLOWLY NWD AND MOST FORECAST MODELS HAVE A DECENT
HANDLE ON THIS FEATURE. THE SYSTEM SHOULD BECOME ABSORBED IN THE
LARGER SCALE FLOW FURTHER NORTH BY MID-WEEK. TROPICAL AIR MASS IN
PLACE ACRS THE SRN HALF OF THE FCST AREA AND THAT WILL BE THE CASE
THRU AT LEAST WED OVER THE ENTIRE FORECAST AREA. PWAT VALUES IN
EXCESS OF 1.75 INCHES COMMON ACRS SRN AND CNTRL IL WITH RAINFALL
RATES WITH SOME OF THE MORE ORGANIZED CONVECTION ON THE ORDER OF 2
TO 3 INCHES PER HOUR...BUT COVERAGE OF THESE IS QUITE SMALL.
SHOWERS AND ISOLATED THUNDERSTORMS WILL BE THE STORY THRU EARLY
THURSDAY AS THE SYSTEM TRACKS ACRS THE LOWER LAKES REGION. TRYING
TO PINPOINT JUST WHERE THE HEAVY RAINFALL WILL OCCUR WL BE DIFFICULT
AT BEST BUT MODELS SEEM TO INDICATE A TREND MORE TWDS THE NORTH
AND WEST OVR THE NEXT 24 TO 36 HOURS. WL HAVE THE USUAL DIURNAL
MAX FOR CONVECTION DURING THE MID AFTN THRU EARLY EVENING HOURS
EACH DAY. MODELS SUGGEST THE WEAKENING UPPER LEVEL DISTURBANCE AND
ASSOCIATED SFC WAVE WL PUSH INTO WRN IL BY TUE AFTN WITH MOST OF
THE AREA...EXCPT THE FAR NORTH...SEEING LOW LEVEL WINDS VEER INTO
THE SSE.

BOTH THE GFS AND NAM-WRF ARE A BIT MORE PROGRESSIVE WITH THE
SYSTEM ON WEDNESDAY INTO THURSDAY...COMPARED TO WHAT WE SAW WITH
THE 12Z RUNS YSTDY. HOWEVER...THE 00Z ECMWF HAS BECOME MORE
PROGRESSIVE AS WELL. THE SRN END OF THE 500 MB TROF LAGS BEHIND
SOME AND MODELS SUGGEST SOME ADDL SHORTWAVE ENERGY MAY TRACK
ALONG THE BNDRY TO OUR SOUTH ON THU BRINGING ADDL RAINFALL TO
PARTS OF THE AREA...ESP ACRS THE SE ON THURSDAY.

LONG TERM...FRIDAY THROUGH MONDAY

THE RAIN THREAT SHOULD SHIFT OFF TO OUR EAST AND SOUTH THURSDAY
NIGHT WITH MEDIUM RANGE MODELS CONTINUING TO SUGGEST A TRANSITION
TO MORE OF A RIDGE WEST...TROF EAST PATTERN FOR LATE IN THE WEEK
AND NEXT WEEKEND...ALTHOUGH THE 00Z ECMWF IS NOT QUITE AS AMPLIFIED
WITH THE ERN U.S. TROF OVER THE WEEKEND. NEXT FRONTAL SYSTEM TO
AFFECT OUR AREA WILL BE LATE SUNDAY OR MONDAY WITH LOW CHANCE POPS
ADDED TO THE GRIDS SUNDAY NIGHT AND MONDAY. WITH THE EURO MODEL
NOT DISPLAYING AS MUCH AMPLITUDE WITH THE TROF TO OUR EAST...IT
APPEARS THE BETTER FORCING/LIFT WL REMAIN TO OUR NORTH AND LOW
LEVEL MOISTURE WL NOT BE THAT PLENTIFUL AHEAD OF THE FRONT. ONCE
THE FRONT SHIFTS TO OUR SOUTHEAST EARLY NEXT WEEK...HIGH PRESSURE
IS THEN FORECAST TO MOVE EAST ACRS THE LOWER LAKES. WITH A LESS
AMPLIFIED SOLUTION...THE FRONT MAY NOT MAKE IT AS FAR SOUTH AS
