AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
655 PM EDT THU MAY 10 2012

.SYNOPSIS...
HIGH PRESSURE WILL BUILD EAST ACROSS THE AREA OVERNIGHT AND THEN
MOVE TO THE CAROLINA COAST BY SATURDAY MORNING.  A COLD FRONT WILL
MOVE SOUTHEAST ACROSS THE REGION SATURDAY NIGHT. MORE HIGH PRESSURE
WILL BUILD IN FROM THE WEST ON SUNDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
GOING FORECAST REMAINS ON TRACK AND ONLY MINOR TWEAKS MADE TO
CLOUD CONDITIONS WITH THIS UPDATE. WINDS REMAIN BREEZY IN EXTREME
NE OH/NW PA WHERE THE GREATEST THREAT FOR FROST WILL BE OVERNIGHT
WITH TEMPERATURES DROPPING INTO THE LOW TO MID 30S. THE PATCHY
NATURE OF THE FROST STILL LOOKS GOOD WITH SOME UNCERTAINTY IF
WINDS WILL GET LIGHT ENOUGH FOR ANYTHING MORE WIDESPREAD. WE WILL
CONTINUE TO CLOSELY MONITOR WINDS/TEMPS AS WE HEAD THROUGH THE
EVENING HOURS.

PREVIOUS DISCUSSION...HIGH PRESSURE WILL BUILD EAST OVERNIGHT
ALLOWING WINDS TO DIMINISH TO VERY LIGHT OR CALM. GOOD RADIATIONAL
COOLING IS EXPECTED OVERNIGHT TO ALLOW TEMPERATURES TO DROP IN THE
EAST. CURRENT TEMPERATURES ARE ONLY IN THE MIDDLE 50S EAST WITH
DEW POINTS IN THE LOWER TO MIDDLE 30S. I EXPECT SOME PATCHY FROST
TO DEVELOP...ESPECIALLY IN THE NORMALLY COLDER LOCATIONS IN INLAND
ERIE AND CRAWFORD COUNTIES OF PENNSYLVANIA ALONG WITH TRUMBULL AND
MAHONING COUNTIES. ELSEWHERE...I EXPECT TEMPERATURES TO REMAIN IN
THE UPPER 30S TO LOWER 40S AND SHOULD BE WARM ENOUGH TO PREVENT
FROST. THERE IS THE POSSIBILITY THAT SOME OF EXTREME COLD SPOTS
COULD SEE SOME FROST TONIGHT AS WELL BUT NOT WIDESPREAD ENOUGH TO
MENTION PATCHY FROST AT THIS TIME.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/...
HIGH PRESSURE WILL CONTINUE TO BE THE DOMINANT WEATHER FEATURE
ACROSS THE AREA ON FRIDAY AS IT MOVES SOUTHEAST TO THE CAROLINA
COAST. AS HIGH SHIFTS EAST...WARM AIR ADVECTION WILL RETURN TO THE
REGION. SATURDAY ALSO APPEARS TO BE A WINNER BUT WITH INCREASING
CLOUDS FROM THE NORTHWEST. AREA REMAINS IN THE SOUTHWEST FLOW AS
WELL SO WILL BE BUMPING UP TEMPERATURES A FEW DEGREES.

A COLD FRONT WILL SLIDE SOUTHEAST ACROSS THE AREA SATURDAY NIGHT.
THE PROBLEM WITH THIS FORECAST IS LIMITED MOISTURE AVAILABILITY WITH
THE FRONT SINCE IT IS ORIGINATING FROM THE PACIFIC. GULF MOISTURE
REALLY DOES NOT HAVE A CHANCE TO GET TAPPED INTO AS THE FRONT
APPROACHES. SO THE THREAT FOR SHOWERS APPEARS TO BE MINIMAL.  WILL
GO WITH SLIGHT CHANCE SATURDAY NIGHT AND A CHANCE TOWARD MORNING
INTO SUNDAY.  PRECIPITATION LAGS BEHIND THE FRONT AND TAKES ITS TIME
GETTING OUT OF THE REGION THROUGH SUNDAY NIGHT.

AIR MASS BEHIND THE COLD FRONT IS NOT REALLY THAT STRONG SO STILL
LOOKING AT TEMPERATURES IN THE LOWER 70S MOST AREAS...EXCEPT UPPER
60S IN THE EAST FOR HIGHS. LOWS IN THE 40S WARMING TO AROUND 50 BY
SUNDAY NIGHT.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
STILL TRYING TO RESOLVE SPLIT FLOW ISSUES FOR NEXT WEEK. IN GENERAL
WILL BE INFLUENCED BY UPPER TROUGH ACROSS THE GREAT LAKES AND NEW
ENGLAND. HAVE CONTINUED THE SAME TRENDS AS PREVIOUS FORECAST WITH
ANY LEFTOVER PRECIP EXITING MONDAY...AND DRY FOR THE REMAINDER OF
THE FORECAST. A WEAK FRONT IS SUPPOSE TO DROP DOWN SOMETIME
WEDNESDAY OR THURSDAY. WILL KEEP SEASONABLE TEMPERATURES.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
HIGH PRESSURE AND DRY STABLE AIRMASS WILL CONTINUE VFR CONDITIONS
ACROSS NRN OHIO AND NWRN PA OVERNIGHT AND FRIDAY.

.OUTLOOK...NON-VFR POSSIBLE LATE SATURDAY NIGHT INTO SUNDAY.

&&

.MARINE...
NEAR SCA CONDITIONS OVER THE EAST PART OF THE LAKE WILL CALM DOWN
SOME TONIGHT AS HIGH PRESSURE MOVES EAST INTO OHIO.  THE FLOW WILL
TURN SW FRI AS THE HIGH MOVES INTO SE OH AND CONTINUE UNTIL TURNING
TO THE NORTH AFTER A WEAK COLD FRONT PASSES SAT EVENING. HIGH
PRESSURE WILL REBUILD INTO THE LAKE SUN AND REMAIN THROUGH TUE TO
KEEP THE FLOW FAIRLY LIGHT WITH MAINLY A N TO NE DIRECTION WITH
DAILY AFTERNOON LAKE BREEZE ENHANCEMENT.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
PA...NONE.
MARINE...NONE.
