AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
152 PM EDT WED JUN 7 2006

.AVIATION /18Z-18Z/...
SURFACE ANALYSIS SHOWS WARM FRONT FROM WESTERN LOWER MICHIGAN TO
SOUTHERN ILLINOIS. RADAR IMAGERY SHOWS PRE-FRONTAL BAND OF SHOWERS
FROM KCMH TO KCVG IS DYING OUT. HOWEVER, SATELLITE AND RADAR SHOWS
A FAVORED AREA OF CONVECTION FROM KDAY TO KBMG. THIS LINE WILL
CONTINUE TO STRENGTHEN IN THE DAYTIME HEATING...AND WILL LIKELY
AFFECT KCVG AND KLUK BETWEEN 19Z AND 21Z.

CONVECTION SHOULD BECOME MORE WIDESPREAD AS UPPER LOW NEAR LAKE
MICHIGAN BEGINS TO FILL IN BUT DIVE SOUTH INTO OHIO LATE THIS
EVENING. THIS WILL CONTINUE THREAT OF SHOWERS THROUGH AFT INTO THE
EVENING BEFORE INSTABILTY WANES AND ONLY SHOWERS ARE LEFT. WILL
BRING SOME MVFR CIGS IN FOR A PERIOD OVERNIGHT AS UPPER LOW SLIDES
INTO OHIO. THESE CONDITIONS ARE COMMON UPSTREAM.

CIGS AND AM FOG WILL BREAK OUT ON THE BACKSIDE OF UPPER LOW
THURSDAY AM.

SHORT TERM /REST OF TODAY/...
SURFACE ANALYSIS SHOWS COLD FRONT ALONG INDIANA/ILLINOIS LINE WITH

HAVE UPDATED WESTERN ZONES TO UP POPS TO LIKELY WITH CURRENT
CONVECTION MOVING THROUGH WEST CENTRAL OHIO AND POISED TO MOVE
INTO THE TRI-STATE. ADDITIONAL CONVECTION IS EXPECTED TO DEVELOP
THIS AFTERNOON OVER INDIANA AND WESTERN OHIO AS STRONG MID LEVEL
WAVE DIVES DOWN INTO THE REGION. ATMOSPHERE IS EXPECTED TO RECOVER

AVIATION /12Z-12Z/...
SHOWERS AND THUNDERSTORMS CONTINUING TO HOLD TOGETHER AS THEY PUSH
ACROSS NORTHEAST INDIANA. IT LOOKS LIKE THEY COULD PASS NEAR OR JUST
NORTH OF THE KDAY TAF SITE THROUGH THIS MORNING SO WILL ALLOW FOR A
COUPLE OF HOURS OF TEMPO -SHRA AND CB THERE. OTHERWISE...EXPECT TO
SEE SCATTERED SHOWER AND THUNDERSTORMS DEVELOP THROUGH THIS
AFTERNOON AS AIRMASS DESTABILIZES SOME AND MID LEVEL SHORT WAVE
PUSHES INTO AREA. DUE TO EXPECTED SCATTERED NATURE...THINK BEST WAY
TO HANDLE THIS AT THIS TIME IS WITH A VCTS. A BIT OF A TRICKY
FORECAST OVERNIGHT TONIGHT AS WEAK SURFACE LOW OVER UPPER GREAT
LAKES IS FORECAST TO PUSH DOWN INTO OHIO THROUGH 12Z THURSDAY AS
BOUNDARY PUSHES ACROSS THE AREA. THERE IS A SMALL AREA OF IFR CIGS
ASSOCIATED WITH THIS LOW UP ACROSS NORTHERN MICHIGAN THIS MORNING
AND THE GFS IS HINTING AT THE POSSIBILITY OF SOME LOW CLOUDS ACROSS
OUR AREA LATER TONIGHT. MEANWHILE...THE NAM IS RELATIVELY DRY. GIVEN
THE CLIMATOLOGICAL TIME OF YEAR...AM HESITANT TO FORECAST IFR CIGS
THAT FAR OUT SO WILL MAINTAIN AN OPTIMISTIC FORECAST FOR NOW.

THE FOLLOWING WAS ORIGINALLY ISSUED AT 516 AM EDT WED JUN 7 2006

SHORT TERM /REST OF TODAY/...
QUICK UPDATE TO ADD LIKELY POPS TO NW ZONES. PRECIP HAS HELD
TOGETHER BETTER THAN PREVIOUSLY THOUGHT.  RLG

 /ISSUED 346 AM EDT WED JUN 7 2006/

SHORT TERM /TODAY THROUGH FRIDAY/...
CURRENT SURFACE ANALYSIS DEPICTS LOW PRESSURE OVER LAKE MICHIGAN
WITH COLD FRONT TRAILING SOUTHWEST THROUGH WESTERN MISSOURI.
RADAR IMAGERY SHOWS SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
OVER CENTRAL INDIANA THIS MORNING. THESE SHOWERS WERE ASSOCIATED
WITH A WEAKENING VORT MAX. ANTICIPATE THIS TO WEAKEN AS IT MOVES
INTO OUR CWA WHICH IS MORE STABLE. GREATER CHANCE OF SHOWERS AND
THUNDER STORMS WILL BE THIS AFTERNOON AS WEAK BOUNDARY APPROACHES
FROM THE WEST AND SHORT WAVE DROPS SOUTHEAST ACROSS THE REGION.
AN ISOLATED SEVERE THUNDERSTORM IS POSSIBLE IN THE WESTERN
CWA...WHICH SPC HAS PLACED UNDER A SLIGHT RISK. WET BULB ZERO
HOVERS AROUND 9000 FT AND SOME MARGINAL INSTABILITY WILL EXIST.
HAVE TAPERED POPS OFF IN THE WEST BY THURSDAY MORNING AND BY
THURSDAY AFTERNOON IN THE EAST. HIGH PRESSURE BUILDS IN FOR
FRIDAY ALLOWING FOR DRY CONDITIONS.

WITH SCATTERED NATURE OF CONVECTION...HAVE BUMPED HIGH
TEMPERATURES UP A DEGREE IS TWO TOWARD WARMER MAV GUIDANCE.
GUIDANCE SEEMED FAIRLY REASONABLE FOR THE REMAINDER OF THE PERIOD
SO USED A BLEND. RLG

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
THE EXTENDED FORECAST IS IN CONSIDERABLE FLUX...PARTICULARLY THE
GFS AND MAV GUIDANCE. THE EXTENDED CONTINUES TO BE DRIER THAN
RECENT WEEKS...AND IS NOW TRENDING COOLER THAN YESTERDAYS RUNS.

FRIDAY AND SATURDAY...THE AREA REMAINS IN N/NW FLOW WITH DRY
CONDITIONS AND HIGH TEMPERATURES BELOW NORMAL.  HAVE BUFFERED THE
NEW LOWER MAV GUIDANCE SOMEWHAT BY NOT TRENDING QUITE AS LOW
FOR HIGH TEMPS AS GUIDANCE AND LOCAL TEMPS APPLIED TO THE 12Z GFS
INDICATE.

FOR SUNDAY...A WEAK DISTURBANCE MOVING ALONG A BNDRY NOW SKIRTS THE
SOUTHERN FCST AREA.  AT THIS POINT...GIVEN THE RUN TO RUN
VARIABILITY...WILL MAINTAIN SLIGHT CHANCE POPS EVEN IN THE NORTH.

THEN MONDAY INTO TUESDAY...SOUTHERLY FLOW SETS UP AS HIGH TEMPS PUSH
WELL INTO THE 80S.  INSTABILITY PICKS UP AND WILL CARRY LOW CHANCE
POPS.
