AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE CLEVELAND OHIO
210 PM EDT THU JUN 30 2005

.SHORT TERM(TONIGHT-SATURDAY)...
COLD FRONT MOVEMENT THROUGH THE WARNING AREA WILL BE THE BIG CONCERN
OF THE CURRENT FORECAST PACKAGE.  CURRENTLY MCS MOVING THROUGH THE
FORECAST AREA AT A RAPID PACE.  THIS LINE WAS GENERATED BY THE
REMANANTS OF AN OLD CONVECTIVE SYSTEM THAT WAS GENERATED LAST
NIGHT.  SHOWERS AND THUNDERSTORMS WILL CONTINUE EARLY THIS EVENING
OVER THE EAST SECTIONS OF THE CWA WITH THE CURRENT SYSTEM.  THE
ACTIVITY SHOULD BE MORE SCATTERED OVER THE WEST SINCE THUNDERSTORMS
HAVE ALREADY WORKED THIS AIR MASS.  THE CURRENT SURFACE ANALYSIS
SHOWS THE COLD FRONT STILL WELL TO THE WEST OVER IL.  THE AIR MASS
IN THIS AREA IS VERY UNSTABLE. CAPE VALUES OVR IL EXCEEDING 3000 IN
SOME AREAS.  WITH THIS IN MIND...I EXPECT THE DEVELOPMENT OF ANOTHER
SQUALL LINE TO THE WEST OF THE FORECAST AREA THIS EVENING AND
OVERNIGHT.  WE SHOULD SEE NUMEROUS SHOWERS AND THUNDERSTORMS
PARTICULARLY IN THE WEST.  GUIDANCE VALUES OVERNIGHT VARY FROM LOW
CHANCE FROM THE FWC TO LIKELY POPS FROM THE MAV AND MET GUIDANCE.  I
AM LEANING MORE TOWARDS THE LIKELY POPS FOR TONIGHT FOR THE CENTRAL
AND WESTERN SECTIONS OF THE AREA.  I WILL KEEP HIGH CHC POPS FOR ALL
OTHER AREAS.  FRIDAY MORNING IS TRICKY.  WHERE WILL THE FRONT BE AND
HOW FAR AHEAD OF THE FRONT WILL THE PCPN BE.  THE PCPN COULD BE WELL
AHEAD OF THE FRONT AND LEAVE MOST AREAS HIGH AND DRY ON FRIDAY.
HOWEVER...I AM NOT COMFORTABLE LEAVING OUT POPS BEFORE THE FRONT
PASSES THROUGH THE FORECAST AREA.  I WILL KEEP CHC POPS ALL AREAS
FRI MORNING AND BRINGING DRYING THROUGH THE DAY.  TEMPS WILL RUN
NEAR GUIDANCE VALUES SINCE THE NUMBERS ARE REASONABLE AND FAIRLY
CONSISTENT.
&&

.LONG TERM (SAT NIGHT THRU THU)...
DRY WEATHER WILL CONTINUE THROUGH THE EARLY PORTIONS OF THE EXTENDED
PERIODS.  HIGH PRESSURE WILL DOMINATE THE WEATHER SUNDAY AND
MONDAY.  A RETURN FLOW WILL SET UP ON THE BACK SIDE OF THE RIDGE ON
SUNDAY.  THIS WILL ALLOW THE TEMPS TO START TO CRAWL BACK INTO THE
80S.  BY MONDAY WE SHOULD HAVE ENOUGH WARM AIR ADVECTION TO LIFT
TEMPS BACK INTO THE MID 80S.  A COLD FRONT WILL DROP INTO THE
FORECAST AREA ON TUE.  THE TIMING OF THE FRONT IS NOT CERTAIN BUT IT
SHOULD IMPACT AT LEAST THE NORTHWEST SECTION OF THE AREA BY 00Z
WED.  I WL KEEP CHC POPS ALL LOCATIONS FOR TUE BUT THE BEST THREAT
WILL BE IN THE NW.  THE GFS SHOWS THE FRONT BOUNDARY STALLING OVER
THE CENTRAL SECTIONS OF OHIO ON WED.  A WAVE DEVELOPS ON THE FRONT
AND MOVES EASTWARD.  IF THIS SCENARIO PLAYS OUT NUMEROUS SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED ON WED.  A SECOND WAVE MAY DEVELOP ON
THE FRONT AS EARLY AS THU.  THESE WEAK WAVES ARE DIFFICULT FOR THE
MODELS TO HANDLE...LET ALONE ON DAY 6 AND 7.  I WILL KEEP CHC POPS
FOR THE FORECAST AREA AT THIS TIME.  WE WILL CONTINUE TO MONITOR THE
TRENDS OF THE EXTENDED MODELS TO DETERMINE IF THE FRONTAL LOCATIONS
AND THE DEVELOPMENT OF SURFACE WAVES IS CONSISTENT.

&&
.AVIATION  (12Z-12Z)...
WIDESPREAD MARGINAL VIS WITH FOG/HAZE THIS MORNING WILL IMPROVE TO
PREDOMINATELY VFR BY MID MORNING. SQUALL LINE STRETCHING FROM MI TO
NWRN INDIANA MOVING EAST AROUND 40KT  SHOULD BEGIN TO DIMINISH AS IT
MOVES INTO SLIGHTLY MORE STABLE AIRMASS...BUT COULD REACH A TOL TO
FDY LINE BEFORE IT DOES DISSIPATE.

THEN LATER THIS AFTERNOON CONDITIONS BECOME UNSTABLE WITH CAPES
EXCEDING 2000 J/KG AND LIS -4 TO -6 PRODUCING SCATTERED
THUNDERSTORMS ACROSS FORECAST AREA...EXPECIALLY WESTERN OHIO.  THEN
OVERNIGHT THE COLD FRONT NOW ACROSS THE MISSISSIPPI VALLEY WILL MOVE
INTO NE BY THIS TIME SATURDAY.
