Area forecast discussion, Jun 27, 1:45 PM CDT, 6 hours 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
145 PM CDT SAT JUN 27 2009

.DISCUSSION...
ISSUED 130 PM CDT SAT JUN 27 2009

MAJOR PATTERN CHANGE TO BRING A COOLER AND MUCH LESS HUMID AIR
MASS SOUTHEAST INTO CNTRL IL STARTING SUNDAY. COLD FRONT...WHICH
WILL BRING THE PLEASANT WEATHER INTO THE AREA...WAS LOCATED JUST
WEST OF DES MOINES AND WILL PUSH EAST INTO THE ILLINOIS RIVER
VALLEY BY LATE THIS EVENING AND EAST OF OUR FORECAST AREA BY
DAWN ON SUNDAY. FAIRLY STRONG TROF FOR THIS TIME OF YEAR EXPCTD
TO DEVELOP OVR THE ERN LAKES EARLY NEXT WEEK KEEPING US IN A
NORTHWESTERLY FLOW PATTERN THRU THE PERIOD.

SHORT TERM...TONIGHT THROUGH TUESDAY

MIXED LAYER CAPES OF AROUND 3200 J/KG EARLY THIS EVENING COUPLED
WITH DECENT MOISTURE CONVERGENCE ALONG THE APPROACHING COLD FRONT
WL HELP TO BREAK ANY REMAINING CAP AND FUEL THE THUNDERSTORMS WITH
THE HIGHER POPS ACRS THE WEST AND NORTH THIS EVENING. FORECAST
SOUNDINGS STILL INDICATING UNIDIRECTIONAL SHEAR WITH MOST LIKELY
CONVECTIVE MODE BEING A SQUALL LINE WITH EMBEDDED BOWS THIS
EVENING...WITH A GRDL DECREASE IN INTENSITY AS THE STORMS SHIFT
FURTHER EAST OVERNIGHT. PRIMARY THREAT WITH THE STORMS THIS EVE WL
BE WITH DAMAGING STRAIGHT LINE WINDS AND PSBLY SOME HAIL...
ALTHOUGH FREEZING LVLS/WBZ HEIGHTS WERE STILL FCST TO BE HIGH THRU
THE EVENING HOURS.

ANY LINGERING SHOWERS ACRS THE FAR SOUTHEAST SHOULD EXIT THE FCST
AREA SUNDAY MORNING WITH GUSTY NORTHWEST WINDS USHERING IN A MUCH
MORE PLEASANT AIR MASS FOR THE RMDR OF THE SHORT TERM PERIOD. MODELS
HAVE BACKED OFF SOME FROM PREVIOUS RUNS WITH RESPECT TO THE PSBLTY
OF ISOLD SHOWERS/THUNDER MONDAY AFTN AS LOW AND MID LEVEL LAPSE
RATES STEEPEN DURING THE AFTN HOURS WITH THE UPPER LOW/COLDER
TEMPS ALOFT SHIFTING SE INTO THE LOWER LAKES. A SECONDARY VORT MAX
AND WEAK FRONTAL BOUNDARY FCST TO PUSH ACRS THE FCST AREA ON
TUESDAY. FORECAST SOUNDINGS CONTINUE TO ADVERTISE A VERY DRY AIR
MASS IN PLACE SO WL NOT ADD ANY POPS INTO THE FORECAST ATTM.

GUID NUMBERS LOOK REASONABLE THRU MONDAY WITH A MAV/MET BLEND BUT
WITH MID 50 DEW POINTS FORECAST ACRS THE AREA FOR THE OVERNIGHT
HOURS OF MONDAY AND TUESDAY...WL TEND TO FOLLOW THE COOLER GUID
VALUES.

LONG TERM...WEDNESDAY THROUGH SATURDAY

STILL SEEING SOME SIGNIFICANT TIMING DIFFERENCES BETWEEN THE
OPERATIONAL GFS AND ECMWF DURING THIS PERIOD. THE GFS CONTINUES
TO SHIFT THE UNSEASONABLY STRONG EASTERN LAKES UPPER LOW OFF TO
THE EAST FASTER THAN THE 00Z RUN OF THE ECMWF. THE LATEST UKMET
AND CMC MODELS SUGGEST A SOLUTION SIMILAR TO THE GFS WITH A
QUICKER MOVMT TO THE ERN LAKES UPPER LOW LATER IN THE PERIOD.
FOR NOW WL CONTINUE TO SIDE WITH THE MORE CONSISTENT ECMWF SOLUTION
WHICH WILL LEAD TO SEASONABLY WARM TEMPERATURES DURING THE PERIOD
WITH LITTLE IF ANY RAINFALL.

SMITH

.AVIATION...
ISSUED 1213 PM CDT SAT JUN 27 2009

COLD FRONT OVER CENTRAL IOWA INTO EXTREME NORTHWEST MISSOURI EARLY
THIS AFTERNOON STILL ON SCHEDULE TO PUSH ACROSS TERMINAL SITES
OVERNIGHT. VERY LITTLE CHANGED FROM 12Z TAF SET AS CONVECTION
STILL LOOKS LIKE IT WILL BE CONFINED TO A NARROW AXIS NEAR THE
FRONT. WILL INTRODUCE VCTS EVERYWHERE 2-3 HOURS PRIOR TO FRONTAL
PASSAGE WITH AN ASSOCIATED TEMPO GROUP WITH VISIBILITIES DOWN TO
3SM. CONVECTION COULD BE LOCALLY INTENSE AND WILL NEED TO BE
MONITORED CLOSELY IN THIS NARROW WINDOW.

FOLLOWING FRONTAL PASSAGE WINDS WILL COME AROUND TO NW AND RAPID
DRYING SHOULD COMMENCE KEEPING ANY BR FROM DEVELOPING.
