AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
656 AM CDT MON APR 4 2011

.DISCUSSION...
ISSUED 320 AM CDT MON APR 4 2011
COLD FRONT ON THE WAY THROUGH CENTRAL ILLINOIS THIS MORNING WITH
LIMITED CONVECTION...SHOWERS...AND PLENTY OF WIND...BOTH IN
ADVANCE OF THE FRONT AND BEHIND IT. PROGRESSION OF THE FRONT IS
STILL NOT WELL AGREED UPON BY OPERATIONAL MODELS AND WITH PLENTY
OF THE PRECIP BEING BEHIND AND ALONG THE BOUNDARY TO THE SW...WILL
KEEP SOME RATHER SIG POPS IN FOR THE MORNING...BUT REDUCE THEM
CONSIDERABLY IN THE AFTERNOON. MODELS THROUGH THE MED RANGE
ACTUALLY NOT TO MUCH OF A SPREAD AND THE FORECAST IS MORE OR LESS
A BLEND. TIMING DIFFERENCES THAT DO EXIST IN THE THU/THU NIGHT
SYSTEM ARE SUBTLE AND STILL WITHIN THE SAME FCST PD.

SHORT TERM...TODAY AND TONIGHT...
BREEZY AND CONSIDERABLY COOLER WITH TEMPS SLOWLY DROPPING THROUGH
THE AFTERNOON FOR THE SE...AND REMAINING RATHER STEADY FOR THE
NWRN HALF OF THE FA. WINDY CONDITIONS TO CONTINUE BEHIND THE FRONT
WITH A RATHER TIGHT PRESSURE GRADIENT STILL...AND SUSTAINED AND
GUSTS APPROACHING ADVSY CRITERIA...BUT MOS GUID AND BUF KIT
MOMENTUM XFER KEEPING IT JUST SHY OF HEADLINES. WILL MONITOR
CLOSELY. PRECIP SLOWLY COMING TO AN END FROM WEST TO EAST...AND
THOUGH MUCH OF IT SHOULD CLEAR BY 18Z...KEEPING SOME POPS THROUGH
THE AFTERNOON IN THE EAST MOSTLY TO BLEND AND COVER ANY REMNANT
SHOWERS WITH A SLOWING BOUNDARY. TONIGHT COOLER ACROSS THE BOARD
WITH LOWS AT OR JUST BELOW FREEZING.

LONG TERM...TUESDAY THROUGH FRIDAY...
SLOW RISE IN TEMPS AGAIN...WITH ALL OPERATIONAL MODELS HINTING AT
A PASSING WAVE JUST NORTH OF CWA FOR TUESDAY NIGHT INTO WED
MORNING. BOTH 00Z ECMWF AND 00Z NAM/WRF KEEP THE PRECIP WELL
NORTH. NOTHING JUST YET IN THE GRIDS...BUT WILL HAVE TO KEEP AN
EYE OUT FOR ACTUAL REPRESENTATION OF THIS PARTICULAR WAVE IN
STRETCHING OUT FLOW WITH A MORE ZONAL LOOK. CURRENTLY OFF PAC
COAST...WILL HAVE TO SEE IF SUBSEQUENT MODEL RUNS PERSIST. NEXT
ISSUE HOLDS OFF UNTIL THURSDAY. FASTER AND MORE AGGRESSIVE GFS
MAINTAINS RAIN AFTER 12Z...ECMWF HOLDING OFF UNTIL AFTER 18Z. TEND
TO LIKE THE ECMWF AS THE NAM/WRF IS ALSO COMING IN ON THE SIDE OF
THE SLOWER SOLN. EITHER WAY...THURSDAY AFTERNOON AND INTO THURSDAY
EVENING RATHER WET IN THE MODEL REPRESENTATIONS BUT HAVE TENDENCY
TO BELIEVE THAT THE LLVL MOISTURE IS OVERDONE...AGAIN. WHEREAS THE
RAIN IS MORE AND MORE LIKELY...THE QPF IS STILL SUSPECT...AND THE
FASTER SOLN A LITTLE LESS LIKELY WITH PLENTY OF DRY AIR IN
PLACE...AND THE SRLY FLOW BEFORE THE SYSTEM APPROACH IS MORE
SWRLY...NOT STRAIGHT OFF THE GULF.

.AVIATION...
ISSUED 656 AM CDT MON APR 4 2011

STRONG COLD FRONT HAS CLEARED ALL CENTRAL ILLINOIS TERMINALS BUT
KCMI...AND IT WILL DO SO SHORTLY THERE AS WELL. GUSTY NORTHWEST
WINDS ARE EXPECTED BEHIND THE FRONT INTO THIS EVENING...THEN THEY
WILL TAPER OFF AS HIGH PRESSURE STARTS TO BUILD INTO THE REGION.
MAINLY MVFR CIGS...WITH A FEW BRIEF IFR POCKETS...ARE EXPECTED
INTO THIS AFTERNOON. THEN...DRIER AIR AND DIURNAL HEATING WILL
RAISE THE CIGS TO VFR. EXPECT SKIES TO CLEAR THIS EVENING AS THE
HIGH PUSHES IN. THE PRECIPITATION HAS LARGELY ENDED AT
KPIA/KBMI/KSPI...BUT WILL STILL IMPACT KCMI AND KDEC FOR A FEW
MORE HOURS.
