.DISCUSSION...
ISSUED 150 PM CDT THU MAR 27 2008

SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
MAIN FORECAST CONCERNS REVOLVE AROUND SNOWFALL POTENTIAL ACRS THE
FAR NORTH TONIGHT AND CONVECTION ALONG AND SOUTH OF BNDRY ACRS
SERN IL. EARLY AFTN SFC MAP INDICATES A WARM FRONT SHIFTING JUST
NORTH OF LAWRENCEVILLE AS LOW PRESSURE EDGES INTO WRN MO. MOST
UNSTABLE AIR MASS JUST EAST AND SOUTH OF THE SFC WAVE AND FRONTAL
BOUNDARY WITH SURFACE BASED LI/S RANGING FROM -4 TO -6. THE LOW
EXPECTED TO PASS ACRS OUR SRN FCST AREA LATER THIS EVENING...ALONG
OR JUST NORTH OF LAWRENCEVILLE BETWEEN 03Z-06Z. BEST THREAT FOR
SFC BASED DEVELOPMENT WILL BE NEAR AND SOUTH OF THE LOW TRACK AND
FRONTAL BOUNDARY...WHILE FURTHER NORTH...SCATTERED ELEVATED
CONVECTION WILL CONTINUE EARLY THIS EVENING WITH MODELS INDICATING
MOST UNSTABLE CAPES IN THE 250-500 J/KG FROM NORTH TO SOUTH.
FURTHER NORTH...ALONG AND NORTH OF THE INTERSTATE 74 CORRIDOR...PRECIP
TYPE BECOMES A PROBLEM. FORECAST SOUNDINGS ACRS THE NORTH SUGGEST
RAIN WILL BECOME MIXED WITH SNOW AND PSBLY SOME SLEET BEFORE CHANGING
OVER TO LIGHT SNOW AFTR 02Z WITH THE BEST FORCING SHIFTING OFF TO
THE EAST JUST AFTR MIDNIGHT (05Z). MAY BE SOME LIGHT ACCUMULATION
(AN INCH OR LESS) NORTH OF I-74 LATER THIS EVENING INTO THE EARLY
MRNG HOURS OF FRIDAY.

THE SHORTWAVE AND ATTENDANT SFC LOW WL PUSH WELL EAST OF THE
FORECAST AREA ON FRIDAY WITH LINGERING POPS HOLDINGS ACRS THE EAST
AND SOUTH...ESP DURING THE MRNG. FAIRLY DECENT PUSH OF DRIER AIR
INDICATED BY MODELS SO WE SHOULD SEE A DECREASE IN CLOUDS FROM
NORTH TO SOUTH BY AFTN AS HIGH PRESSURE SETTLES IN. THE HIGH WILL
HOLD ACRS THE LAKES REGION THRU MOST OF SATURDAY BEFORE PUSHING
WELL OFF TO OUR EAST BY AFTN ALLOWING A RETURN FLOW OF MOISTURE
BACK INTO CNTRL IL AHEAD OF ANOTHER STORM SYSTEM PUSHING INTO
KS AND OK. A WARM FRONT WL DEVELOP TO OUR SOUTH SATURDAY NIGHT AND
INCREASING LOW LVL WINDS OUT OF THE SOUTH WILL HELP TO TRANSPORT
MOISTURE NWD OVER THE SFC AND 850 MB BOUNDARIES TO OUR SOUTH
RESULTING IN AN INCRG THREAT FOR SHOWERS AND THUNDERSTORMS
SATURDAY NIGHT THRU SUNDAY NIGHT. MODELS SUGGESTING SVL SHORTWAVES
TO EJECT OUT OF THE SRN PLAINS THRU SUNDAY AND INTERACT WITH THE
BOUNDARY ACRS CNTRL IL TO KEEP THE WEATHER QUITE UNSETTLED THRU
THIS PERIOD AND BEYOND. MODELS INDICATING PRECIP WATER VALUES
APPRCHG 1.50 BY SUNDAY AFTN AND EVENING WITH HEAVY RAINFALL ONCE
AGAIN A DISTINCT POSSIBILITY.

LONG TERM...MONDAY THROUGH THURSDAY
A VERY ACTIVE PATTERN WL CONTINUE DURING THIS TIME FRAME AS THE
PROGRESSIVE FLOW PATTERN FROM THE CNTRL PACIFIC EWD INTO THE
MIDWEST WL BRING PERIODIC CHANCES FOR SHOWERS AND THUNDERSTORMS TO
CNTRL IL. IT APPEARS THE GFS IS SUFFERING FROM SOME FEEDBACK
PROBLEMS...STARTING AS EARLY AS SATURDAY NIGHT...AND ESPECIALLY
SUNDAY NIGHT INTO MONDAY WHICH RESULTS IN A STRONGER SURFACE WAVE
THAN WHAT IS DEPICTED ON THE 00Z ECMWF. HAVE TRENDED MORE TWDS THE
ECMWF SOLUTION WITH THE TIMING OF THE WAVES AND PRECIP INTO CNTRL
IL DURING THIS PERIOD. APPEARS THE HIGHER PROBABILITIES OF SHOWERS
AND THUNDERSTORMS WILL BE MONDAY INTO EARLY TUESDAY AND THEN AGAIN
WEDNESDAY NIGHT INTO THURSDAY AS ANOTHER SIGNIFICANT SHORTWAVE
SHIFTS EAST INTO THE MIDWEST. LIKE ITS PREDECESSOR...THE MIDWEEK
SYSTEM WILL HAVE DEEP MOISTURE ADVECTING NWD INTO A FRONTAL
BOUNDARY WHICH WILL BE LOCATED ACRS CNTRL IL. AGAIN...ANOTHER
SIGNIFICANT RAIN MAKER FOR PARTS OF THE FCST AREA DEPENDING ON
WHERE THE BOUNDARY SETS UP. ONE THING THAT WAS NOTICED ON THE NEW
12Z ECMWF WAS A STRONGER ERN US RIDGE WHICH WOULD ALLOW A FURTHER
NORTH AND WEST TRACK ON THE LOW...RESULTING IN NOT ONLY A HEAVY
RAIN THREAT BUT ALSO AN ENHANCED THREAT FOR SEVERE WEATHER LATE
MONDAY INTO EARLY TUESDAY.

AS THE LATE MON/TUE SHORTWAVE SHIFTS TO OUR EAST...QUIET WX WL
SETTLE IN TUE AFTN INTO WEDNESDAY BEFORE ANOTHER PACIFIC SHORTWAVE
AND FRONTAL SYSTEM START TO AFFECT THE MIDWEST EITHER LATE WED OR
THURSDAY WITH INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS.
