655 PM EDT WED MAY 31 2006

.AVIATION(00Z-24Z)...
UNSTBL AMS AHEAD OF CDFNT IN THE NW WL CONT TO TOUCH OFF SHWRS/TSTMS
OVRNGT ALTHOUGH BLV COVERAGE WL DCRS WITH SUNDOWN.  WL CONT WITH
PREDOMINANT SHWRS/TSTMS TOL FDY AREAS IN THE VCNTY OF THE FRONT BUT
BGN WITH DRY CONDS OR VCNTY WORDING ELSEWHERE. THRU THE NIGHT AND
INTO THE MORNING XPC FOG TO DVLP.  WILL BRING VSBYS DOW TO MVFR BY
ABOUT 06Z AND WOULD XPC PERIODS OF IFR VSBYS AROUND SUNRISE.  AMS
REMAINS MOIST AND AMARGINALLY UNSTABLE THURSDAY AND WILL GO WITH
CIGS BTWN 035 AND 050 AND MVFR VSBYS IN SCT SHWRS.  AVAILABLE ENERGY
(CAPE) IS FCST TO REACH 100 J/KG THURS AFTN SO WOULD XPC TSTMS TO
DVLP AGAIN ACRS THE AREA.  WILL GO WITH VCTS FOR NOW.

&&

.SHORT TERM(TNT-SAT)...
SLOW MOVING FRONT LAYING FROM MI TO ORD AND SOUTHWEST.  ALONG AND
SOUTH OF THE FRONT ATMOS MOIST/UNSTABLE WITH LOCAL BOUNDARIES AND
DAYTIME HEATING PROVIDING THE NEEDED SUPPORT FOR STRONG
THUNDERSTORMS.  RAINFALL IS LOCALLY HEAVY WITH THE THUNDERSTORMS.
THESE THUNDERSTORMS SHOULD CONTINUE FOR THE NEXT SEVERAL HOURS...BUT
DIMINISH AFTER DARK FOR A TIME...WITH THE WESTERN STORMS LIVING ON.
POPS WILL STAY IN THE FORECAST FOR THE OVERNIGHT HOURS AS
FRONT WILL BE SLOWLY SINKING INTO THE AREA.  PATTERN WILL MOVE IN
SLOW MOTION AS IT WILL TAKE TIL FRI FOR THE SHORTWAVE OVER THE
DAKOTAS TO MAKE IT TO THE SOUTHERN GREAT LAKES AND THEN IT WILL BE
NEAR THE END OF THE WEEKEND BEFORE WE CAN LOSE THE TROUGH AND ITS
EFFECTS.

LOCATIONS THAT BECOME POST FRONTAL OVERNIGHT WILL LOSE THE TS
CHCS...DIDNT GET FANCY WITH THIS IN THE GRIDS DUE TO THE
UNCERTAINTY ON EXACT TIMING OF THE FRONTAL PASSAGE.  FRONT SHOULD BE
IN EASTERN SECTIONS OF CWA BY MORNING. CANT ARGUE WITH GUID TEMPS
TONIGHT...TIGHTLY CLUSTERED.  TEMPERATURES RETURN TO NORMS WITH
PASSAGE OF FRONT.

CHC OF SHOWERS CONTINUE INTO THE WEEKEND...MAINLY DIURNAL AS UPPER
TROUGH MOVES THROUGH.
&&

.LONG TERM(SUN-WED)...
THE SOLUTION OF A RIDGE BUILDING BACK INTO THE REGION LOOKS MORE
DISTANT AS CONSENSUS AMONGST MODELS SUGGESTING SOME SORT OF EAST
COAST TROUGH.  RESIDENCE TIME OF SOUTHEAST H5 LOWERED HEIGHTS
QUESTIONABLE AND TIMING OF SHORTWAVES RIDING TOP OF PLAINS RIDGE TOO
VARIABLE AT THIS TIME TOO.  SURFACE RIDGE BUILDS IN SUN...BUT WILL
KEEP POPS FOR MON AND ADD FOR TUE WITH POSSIBLE ACTIVITY RIDING THE
RIDGE AND A FRONT IN THE VICINITY AROUND WED.  REASONABLE TEMPS.
&&

.SHORT TERM(TODAY-FRI)...
COLD FRONT WILL BE APPROACHING THE AREA TODAY. MODEL DIFFERENCES
ESPECIALLY TONIGHT AND THURSDAY WITH THE GFS/ECMWF/UMKET MOVING THE
COLD FRONT MUCH FASTER THAN THE NAM. SOME QUESTION WITH THE FLOW
SOMEWHAT PARALLEL TO FRONT THAT IT WILL MOVE QUICK...ATTM WILL
CONTINUE THE SLOW NAM TREND...THIS MEAN LIKELY POPS IN THE EASTERN
COUNTIES ON THURSDAY. A FEW ISOLATED CELLS HAVE DEVELOPED IN CENTRAL
OHIO DURING THE EARLY MORNING IN THE MOIST AND UNSTABLE AIRMASS.
THE PROBLEM FOR TODAY IS THE AIRMASS IS MORE UNSTABLE EAST WHERE IT
IS NOT AS MOIST WHILE IN THE WEST IT IS MORE MOIST BUT NOT AS
UNSTABLE. NO OTHER GOOD DYNAMICS EXCEPT FOR THE INSTABILITY AND COLD
FRONT. THE NAM HAS REALLY HIGH CAPE IN THE EAST THIS AFTERNOON...THE
GFS HAS LOWER VALUES BUT THEY ARE IN THE SAME PLACE. A WEAK LAKE
BREEZE SHOULD DEVELOP AND MOVE A MILE OR SO INLAND. SOME TSTMS COULD
DEVELOP ON THAT. THE SEVERE WEATHER THREAT WILL BE WIND AND
HAIL...DELTA THETA E VALUES ARE IMPRESSIVE...HAIL THREAT IS
MODERATE. WILL MENTION CHANCE OF SEVERE IN THE GRIDS AND ZONES ALONG
WITH HWO. TONIGHT WILL JUST FORECAST CHANCE WITH MOISTURE AND
BOUNDARY AROUND. THE SEVERE THREAT SHOULD DECREASE WITH SUNSET.
IF THE BOUNDARY IS IN THE AREA THURSDAY NIGHT WILL HAVE TO CONTINUE
THE THREAT IN THE EASTERN COUNTIES. THE THREAT CONTINUES ON
FRIDAY WITH SOME MOISTURE AND OMEGA IN THE AREA.

GUIDANCE TEMPERATURE LOOK GOOD. TODAY IS TOUGH IF THE CLOUDS THICKEN
EARLY THAT COULD SHAVE A FEW DEGREES OFF THE FORECAST.

&&

.LONG TERM (FRI NGT-TUE)...
NO MAJOR CHANGES TO EXTENDED...TIMING IS TOUGH WITH RIDGE IN THE
AREA BUT SOME TROFINESS AT TIMES.
TAKING THE ROUTE OF SLOWER THAN THE GFS FOR EVOLUTION OF NORTHWEST
FLOW/ NEW ENGLAND TROUGH TO A BIT MORE ZONAL TO RIDGING PATTERN.
TEMPS MAY INCREASE TOWARD THE END OF THE PERIOD INTO THE LOWER
80S...OTHERWISE NEAR NORMAL.
