AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
324 PM EDT THU MAY 27 2010

.SYNOPSIS...
A WEAK UPPER LEVEL DISTURBANCE WILL MOVE SOUTHEAST ACROSS THE
LOCAL AREA THIS EVENING. A COLD FRONT MOVING SOUTH ACROSS WESTERN
NEW YORK WILL AFFECT NORTHWEST PENNSYLVANIA AND NORTHEAST OHIO ON
FRIDAY. HIGH PRESSURE WILL BUILD OVER THE REGION SATURDAY AND
SUNDAY. A COLD FRONT WILL MOVE ACROSS THE LOCAL AREA ON MONDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
SCATTERED SHRA/TSRA CONTINUE TO DEVELOP OVER OUR WESTERN TWO TIERS
OF COUNTIES. MORE STORMS LIKELY THIS EVENING AS AN UPPER
DISTURBANCES DIVES SOUTHEAST ACROSS THE AREA. EXPECT MOST OF THIS
ACTIVITY TO BE OVER THE WESTERN THIRD OF THE AREA. WILL HOWEVER...
KEEP AT LEAST 20 POPS OVER THE ENTIRE AREA THROUGH THE EVENING
OURS. LAST NIGHT...MOST OF THE ACTIVITY TO THE WEST WAS GONE BY
03Z AND EXPECT A SIMILAR SCENARIO TONIGHT. A FEW OF THE STRONG
STORMS COULD APPROACH SEVERE LIMITS...ESPECIALLY THE NEXT COUPLE
OF HOURS. WET BULB ZERO TEMPS ONLY AROUND 9K FEET SO HAIL WILL BE
THE MAIN THREAT. A DOWNBURST OR TWO WILL ALSO BE POSSIBLE. WILL
FRESHEN THE HWO TO HI-LIGHT CONCERNS. GUIDANCE TEMPS IN THE
BALLPARK.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH MONDAY NIGHT/...
BACK DOOR COLD FRONT STILL ON TRACK TO AFFECT NW PA AND NE OH ON
FRIDAY. EXPECT SOME MORE SCATTERED SHRA/TSRA TO DEVELOP DURING THE
DAY. BEST CHANCES FOR STORMS WILL BE OVER NW PA BUT SMALL CHANCES
WILL STRETCH AS FAR WEST AS THE I-71 CORRIDOR. LOCATIONS FURTHER
WEST WILL REMAIN DRY. HIGH PRESSURE WILL ESTABLISH ITSELF OVER THE
AREA BOTH SATURDAY AND SUNDAY. TEMPS WILL BE WARM WITH HIGHS BOTH
DAYS WELL INTO THE 80S. STILL MODEL DIFFERENCES ON MONDAY. GFS

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
THE BEST CHANCE FOR CONVECTION THROUGH THIS EVENING IS OVER
WESTERN OHIO WHERE THE AIR MASS IS MOIST AND UNSTABLE ENOUGH AND
CONVECTION HAS STARTED TO DEVELOP. IT IS POSSIBLE THAT SOME ISOLATED
SHOWERS OR THUNDERSTORMS COULD OCCUR OVER THE SOUTHEAST PORTION
OF THE FORECAST AREA THROUGH THIS EVENING. CONFIDENCE IS LOWER IN
THAT AREA. FOR THE TAF SITES WILL ONLY MENTION TSRA OR CB FOR
TOL...FDY AND MFD. THE SHOWERS/THUNDERSTORMS SHOULD DECREASE
QUICKLY AFTER SUNSET. SOME AREAS OF MVFR FOG MAY DEVELOP AND BURN
OFF BY 14Z.

FOR FRIDAY THE MAIN THREAT OF CONVECTION WILL BE OVER
THE EASTERN PORTION OF THE FORECAST AREA AS THE BACKDOOR COLD
FRONT MOVES TOWARD THE REGION. THE AIR MASS IS NOT REAL MOIST SO
THE THREAT OF CONVECTION WILL BE LIMITED. THE TAF SITES THAT HAVE
THE BEST CHANCE TO BE IMPACTED WILL BE YNG AND CAK.
