Area forecast discussion, Jun 8, 2:03 PM EST, 4 hours 57 minutes before

AREA FORECAST DISCUSSION...ISSUED BY CLEVELAND OHIO
NATIONAL WEATHER SERVICE BUFFALO NY
302 PM WED JUN 8 2005

.SHORT TERM (TONIGHT THROUGH SATURDAY)...
FRONTAL BOUNDARY REMAINS NEARLY STATIONARY ACROSS THE NORTHERN
SECTIONS OF THE FORECAST AREA.  A FEW SHOWERS AND THUNDERSTORMS HAVE
DEVELOPED NORTH OF THE BOUNDARY ACROSS LAKE ONTARIO AND ARE MOVING
INTO THE EXTREME NORTHEAST SECTIONS OF THE FORECAST AREA.  THE
MODELS INDICATE THAT THIS BOUNDARY WILL MOVE NORTH OVERNIGHT. THIS
WILL KEEP MOST OF THE AREA IN THE WARM SECTOR.  THE HEIGHTS RISE
OVER THE REGION TOMORROW AND 850MB TEMPS WILL REMAIN AROUND +16.
WITH SW FLOW I EXPECT A SIMILAR TEMPERATURE PATTERN ON THU AS WE
HAVE TODAY.  THE INLAND AREAS SHOULD ONCE AGAIN BE AROUND 90.  THE
SOUTHERN HIGH COUNTRY IN THE MID 80S AS WELL AS BUF.  THE PATTERN
REMAINS PERSISTENT THROUGH FRIDAY SO I DO NOT SEE MUCH OF A CHANGE
ON FRIDAY.  DIURNAL INSTABILITY WILL ALSO EXIST THROUGH THE PERIOD
SO SCATTERED AFTERNOON THUNDERSTORMS WILL DEVELOP EACH DAY.  THIS IS
HANDLED IN THE CURRENT FORECAST AND FEW ADJUSTMENTS WILL BE MADE.

&&

.LONG TERM (SUNDAY THROUGH WEDNESDAY)...
LARGE BERMUDA HIGH WILL DOMINATE THE WEATHER PATTERN OVER THE
EXTENDED PERIOD.  THIS SHOULD LEAD TO A PERIOD OF FAIRLY CONSIST
SUMMER LIKE WEATHER.  THE GFS SHOWS HIGH RH VALUES MOVING AROUND THE
WEST SIDE OF THE RIDGE AND SETTLING OVER THE EASTERN LAKES.  THIS
MOISTURE MAY BE OVER DONE SINCE SIGNIFICANT ADVECTION OF MOISTURE
FROM THE SOUTH IS NOT PRESENT THIS WEEKEND.  THE GFS IS CONSISTENT
WITH THE MOVEMENT OF A TROPICAL SYSTEM FROM THE GULF AROUND THE WEST
SIDE OF THE BERMUDA HIGH.  THE GFS TRACKS THE REMNANTS OF THIS
SYSTEM INTO THE OHIO VALLEY AND WESTERN NY AS EARLY AS TUE OF NEXT
WEEK.  IF THIS SOLUTION IS REALISTIC...NUMEROUS SHOWERS MAY EXIST
OVER THE REGION FOR THE EARLY TO MID PART OF NEXT WEEK.  AT THIS
TIME I WILL KEEP THE POPS AT CHC VALUES.  TEMPS WILL REMAIN WARM
THROUGH THE PERIOD.  I WILL NOT STRAY FAR FROM GUIDANCE.

&&
.AVIATION 18Z-18Z...
HIGH PRESSURE TO CONT TO DOMINATE WX CONDS FOR NEXT 24 HOURS OR SO.
A LIGHT SOUTHERLY FLOW WILL COMBINE WITH SOME RELATIVELY WEAK
INSTABILITY TO PRODUCE SCATTERED OR WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS. FOR THE MOST PART LOOK FOR VFR CONDS. SOME VSBY
RESTRICTIONS ARE POSSIBLE OVR NITE. WILL MENTION SOME PCPN FOR THIS
AFTN.
