NATIONAL WEATHER SERVICE WILMINGTON OH
134 PM EDT TUE JUN 28 2005

.AVIATION (18Z-18Z)...
WEAK SHORTWAVE AND MODERATE INSTABILITY ALLOWING FOR CONVECTION TO FIRE
THIS AFTERNOON.  MVFR BR/HZ WILL OCCUR ONCE AGAIN OVER NIGHT ACROSS ALL
SITES.  CONVECTION WILL BE POSSIBLE ONCE AGAIN AS A WEAK VORT
APPROACHES AND INSTABILITY EXISTS.

&&

.PREVIOUS DISCUSSION...
(ISSUED 1138 AM EDT TUE JUN 28 2005)

SHORT TERM (REST OF TODAY)... UPDATE OUT SHORTLY TO CLEAN UP
MORNING WORDING AND ADJUST TEMPERATURES.  ACROSS THE SOUTHWEST
WHERE SKIES ARE CURRENTLY PC HAVE RAISED TEMPERATURES TO NEAR 90
RATHER THAN UPPER 80S.  KEPT LIKELY POPS ACROSS ENTIRE CWA.  WITH
AFTERNOON HEATING...MODERATE INSTABILITY IN PLACE AND WEAK VORT
PASSING THROUGH...SHOWERS AND THUNDERSTORMS SHOULD NOT HAVE
TROUBLE FORMING.

PREVIOUS DISCUSSION...
(ISSUED 747 AM EDT TUE JUN 28 2005)

AVIATION (12Z-12Z)...
SHOWERS AND THUNDERSTORMS ASSOCIATED WITH UPPER TROF AND S/W
CURRENTLY PUSHING NORTHEAST...NORTH OF TAF SITES.  EXPECT MORE
DEVELOPMENT AS HEATING OCCURS.  MVFR HZ/BR WILL OCCUR AGAIN
TOMORROW MORNING.  KLUK MAY EXPERIENCE IFR FG...ESPECIALLY IF
RAINFALL OCCURS THERE TODAY.

PREVIOUS DISCUSSION...
(ISSUED 249 AM EDT TUE JUN 28 2005)

SHORT TERM (TODAY THROUGH WEDNESDAY NIGHT)...
THERE WAS SOME ISOLATED CONVECTIVE ACTIVITY...MAINLY SW OF THE FCST
AREA...ASSOCIATED WITH AN UPPER LOW/TROF.  TEMPERATURES WERE MAINLY
IN THE LOW TO MID 70S.

FOR TODAY...THE AFOREMENTIONED UPPER TROF AND S/W WILL WORK ACROSS
THE AREA.  THERE IS MODERATE INSTABILITY WITH PW(S) AROUND 1.75
INCHES.  GIVEN THIS...AND CONSIDERING MET AND MAV GUIDANCE POPS...IT
APPEARS THAT COVERAGE WILL BE MORE EXPANSIVE THAN MONDAY...SO HIGH
LIKELY POPS WHICH ARE A BIT BELOW THE MAV AND MET GUIDANCE SEEMS
REASONABLE...TAPERING OFF INTO THE EVENING.

TONIGHT...WILL CARRY ONLY SLIGHT CHANCE POPS AFTER MIDNIGHT.
LOW TEMPS WILL BE SOMEWHAT LOWER THAN THIS MORNING IN THE UPPER 60S
TO LOWER 70S.

ON WEDNESDAY...ANOTHER S/W MOVES ACROSS THE FCST AREA. NAM TIME
HEIGHT PROFILES SHOW MORE MID AND HIGH LEVEL MOISTURE THAN THE GFS
DOES...AND THIS IS REFLECTED IN HIGHER MAV THAN MET GUIDANCE HIGH
TEMPS...IN THE LOWER 90S COMPARED WITH MID TO UPPER 80S.  ALSO...MAV
GUIDANCE POPS ARE LOWER AS WELL.  WILL COMPROMISE ON BOTH...LEANING
SOMEWHAT TOWARD THE MAV/GFS...WITH CHANCE POPS TAPERING OFF INTO THE
EVENING AGAIN WITH LOWS NEAR 70 WEDNESDAY NIGHT.

PREVIOUS DISCUSSION...
(ISSUED 150 AM EDT TUE JUN 28 2005)

AVIATION (06Z-06Z)...
TIMING CONVECTION AT TAF SITES WILL BE MAIN CHALLENGE. MOST
ACTIVITY HAS DIMINISHED ACROSS THE AREA BUT CANNOT RULE OUT SOME
DEVELOPMENT BEFORE DAYBREAK ESPECIALLY IN WESTERN LOCATIONS CLOSER
TO AXIS OF SHEARED SHORT WAVE. HAVE DECIDED TO HOLD OFF ON
PRECIPITATION FOR THE SCHEDULED RELEASE AND CONTINUE TO MONITOR
TRENDS. BETTER CHANCE OF CONVECTION WILL COME WITH HEATING.
LIMITED TEMPO TSRA TO EARLY TO MID AFTERNOON WITH VCTS OR CB
DESIGNATOR USED AT TIMES OF LOWER PROBABILITY. IT APPEARS THAT
SHOWERS AND THUNDERSTORMS WILL HAVE DIMINISHED AND/OR MOVED EAST
OF THE TAF SITES BEFORE 00Z.

(ISSUED 340 PM EDT MON JUN 27 2005)

LONG TERM (WEDNESDAY THROUGH MONDAY)...
CDFNT LOCATED NEAR OR N OF FCST AREA STARTING 12Z WED. SLY FLOW
AHEAD OF IT COMBINED WITH AXIS OF H5 TROF AT ROUGHLY THE SAME TIME
WILL INCREASE CHANCE OF SHOWERS OVER FCST AREA DURING THE DAY. HAVE
ENDED PRECIP OVER THE WEST BY 0Z THURS AND THE EAST BY 6Z AS THE
FRONT WASHES OUT AND NEVER GETS THROUGH THE FCST AREA. DAYTIME HOURS
ON THURS BRINGS ANOTHER FRONT RIDING ALONG WASHED OUT BOUNDARY FROM
PREVIOUS ONE WITH THE LOW IN THE UPPER MIDWEST TRACKING N OF THE
GTLKS. H5 PATTERN WEAKENS BUT THE MEAN TROFFINESS GENLY RUNS FROM
SRN GTLKS THROUGH THE OH AND TNVLYS. OVERNIGHT WED SHOWS THE NRN
PORTION OF THE H5 TROF BECOMING ZONAL FROM ABOUT THE OHRVR NWD. THE
SFC FNT THURS BECOMES MORE OPEN AS THE FORCING SHIFTS WELL TO THE N.
WAVES WILL MOVE THROUGH THE ZONAL FLOW AND ONLY CHANCE POPS EXPECTED
LATER IN THE DAY WITH BEST CHANCE TO THE N...LOW OR SCHC TO THE S AS
THE SFC WAVE OPENS.

BY FRI...GFS HAS SOME POST FRONTAL SHOWERS TO THE S EARLY IN THE
DAY...WILL LEAVE OUT ATTM UNLESS SRN FCST OFFICES ARE HITTING IT UP.
SFC HI BUILDS OVER THE UPPER MIDWEST AND NRLY FLOW IS PROGGED OVER
FCST AREA THROUGH 18Z SAT AS THE HI TRACKS TOWARD KTOL. STILL A GOOD
AMOUNT OF DOWNWARD MOTION SAT AND SAT NIGHT WHILE SUN SEES RETURN
FLOW WHICH JUST SLIGHTLY BUILDS H5 HEIGHTS. FCST TO REMAIN DRY SUN
AS THE SFC FRONT AND ANY FORCING IS IN THE MIDWEST...WELL W OF FCST
AREA. H5 HEIGHTS CONTINUE TO BUILD SUN AND MON...AND THE SFC FNT
ISNT PROGGED TO BE ANYWHERE NEAR FCST AREA DURING THIS TIME. A
QUICKER PROGRESSION MAY LEAD TO SHOWER ACTIVITY LATER MON...WILL
LEAVE OUT PRECIP ATTM AND SEE WHERE ITS PROGGED TOMORROW.

MAV IS TOO WARM AND TOO DRY ON WED...ALTHOUGH THE TREND IS TO LOWER
POPS AND INCREASE TEMPS. PREFER THE BLEND OF MAV/MET WHICH IS CLOSE
BUT SLIGHTLY COOLER THAN FWC AND CLOSE TO FWC POPS. RAISED A DEGREE
FROM PREVIOUS FCST WED AND WED NITE...SIMILAR TO PREV FCST THURS AND
THURS NITE. ON FRI...HIGH BUILDS IN AND NRLY FLOW KEEPS COOLER TEMPS
OVER FCST AREA...POSSIBLY DIPPING INTO THE 50S OVERNIGHT. SAT TEMPS
WERE TOO COOL...EVEN WITH CAA...SKIES SHOULD BE MOCLEAR AND THIS
WILL ALLOW BOUNDARY LAYER TO RISE INTO THE 80S WITH LOWER
HUMIDITIES. HIGH MAINTAINS COOLER AND DRIER AIR OVER US SAT AND SAT
NIGHT...WITH A SLOW INCREASE IN TEMPS EXPECTED SUN AND MORE SO ON
MON.
