DISCUSSION
KEY MESSAGE 1...
THE LATEST RADAR AND SATELLITE IMAGERY REVEAL A LARGE AREA OF
CLOUDS AND GENERALLY LIGHT RAIN SHOWERS ACROSS THE UPPER OHIO
VALLEY AND LOWER GREAT LAKES THIS AFTERNOON, ASSOCIATED WITH A
SURFACE TROUGH AHEAD OF A BROAD UPPER-LEVEL FEATURE TO THE WEST
ACROSS THE UPPER MIDWEST. SURFACE OBSERVATIONS ALSO DEPICT A
STATIONARY FRONT LOCATED FURTHER SOUTH NEAR THE LOWER OHIO
VALLEY, THUS THUNDER CHANCES FOR OUR AREA THROUGH WEDNESDAY WILL
REMAIN LIMITED. OCCASIONAL RAIN SHOWERS, PARTICULARLY ACROSS
PORTIONS OF NORTH-CENTRAL AND NORTHEAST OHIO, WILL CONTINUE INTO
THIS EVENING, BEFORE LARGELY DISSIPATING OVERNIGHT. CAN'T RULE
OUT RAIN PERSISTING ACROSS A SMALL PORTION OF NORTHWEST OHIO
OVERNIGHT INTO TUESDAY ALONG THE SURFACE TROUGH, THOUGH COVERAGE
SHOULD BE MORE ISOLATED AND LIGHT ELSEWHERE. THE NEXT CHANCE
FOR WIDESPREAD AND PERHAPS A MORE STEADY RAIN MAY RETURN LATE
TUESDAY NIGHT INTO WEDNESDAY AS THE UPPER-LEVEL FEATURE
APPROACHES THE AREA, WITH AN INCREASING ARC OF 850 MB E TO SE
WINDS TRANSPORTING MORE FAVORABLE MOISTURE INTO THE AREA.
PERIODIC RAIN SHOWERS AND CLOUD COVER WILL CONTRIBUTE TO BELOW
AVERAGE DAYTIME TEMPERATURES IN THE 60S OR PERHAPS EVEN UPPER 50S AT
TIMES AND LOWS IN THE 50S OR UPPER 40S.
KEY MESSAGE 2...
HIGH PRESSURE WILL BUILD SOUTH ACROSS THE GREAT LAKES BY THE
END OF THE WEEK AND LIKELY PERSIST THROUGH THE WEEKEND. INITIALLY,
HIGH PRESSURE AND THE DEPARTING CHILLY AIR MASS COULD RESULT IN
A FAVORABLE SCENARIO FOR SOME LOWS IN THE UPPER 30S TO DEVELOP,
PARTICULARLY ACROSS INLAND NORTHWEST PENNSYLVANIA, THOUGH 40S
SHOULD BE MORE COMMON ELSEWHERE. THE AIR MASS WILL GRADUALLY
MODERATE THROUGH THE WEEKEND WITH HIGH PRESSURE IN PLACE AS
TEMPERATURES RETURN TO THE UPPER 60S TO LOW 70S BY SUNDAY.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
A SIMILAR PATTERN AS OBSERVED ON MONDAY IS EXPECTED TO PERSIST
INTO TUESDAY AS SCATTERED LIGHT RAIN SHOWERS REMAIN POSSIBLE FOR
MUCH OF THE DAY. IN ADDITION, MANY TERMINALS ARE ALREADY NON-VFR
THIS MORNING WITH LOW CEILINGS BEING THE PRIMARY DRIVER OF THESE
CONDITIONS. THERE IS ISOLATED AREAS OF 4SM OR LESS WITH MIST
BEING REPORTED, BUT GIVEN THE BREEZY CONDITIONS NOT EXPECTED
MUCH IN TERMS OF FOG. THERE REMAINS QUITE A BIT OF UNCERTAINTY
IN THE AVIATION FORECAST GIVEN THE EXPECTED SCATTERED NATURE OF
SHOWERS AND UNCERTAINTY WITH HOW FAR NORTH LOW CEILINGS WILL
PUSH. HAVE OPTED TO HANDLE MUCH OF THE PRECIPITATION CHANCES
WITH TEMPO/PROB30. OVERALL, AVIATION CONDITIONS ACROSS THE AREA
TODAY WILL LIKELY BOUNCE AROUND FLIGHT CATEGORIES. THE ONLY
EXCEPTION IS KERI WHICH SHOULD REMAIN VFR.
NORTHEAST WINDS OF 10-15 KNOTS THIS MORNING WILL BECOME GUSTY
IN THE 20-25 KNOT RANGE BY THIS AFTERNOON. THE STRONGEST GUSTS
WILL OCCUR NEAREST THE LAKESHORE AND ALONG THE I75 CORRIDOR.
OUTLOOK...NON-VFR POSSIBLE WITH SHOWERS AND OCCASIONAL
THUNDERSTORMS THROUGH THURSDAY.
MARINE
ROUGH MARINE CONDITIONS WILL CONTINUE ACROSS LAKE ERIE THROUGH
WEDNESDAY WITH PERSISTENT EAST TO NORTHEAST WINDS OF 20 TO 30 KNOTS
RESULTING IN WAVE HEIGHTS OF 4 TO 7 FEET. CONDITIONS WILL REMAIN
CHOPPY ON THURSDAY AS NORTHEAST FLOW ONLY GRADUALLY IMPROVES TO 15
TO 20 KNOTS. WINDS WILL CONTINUE TO GRADUALLY WEAKEN ON FRIDAY INTO
SATURDAY, THOUGH WILL REMAIN OUT OF THE NORTH TO NORTHEAST WITH THE
BUILDING HIGH PRESSURE TO THE NORTH, 10 TO 15 KNOTS.
GIVEN THE LINGERING SURFACE TROUGH DRAPED ACROSS LAKE ERIE, CAN'T
RULE OUT A SMALL CHANCE OF WATERSPOUTS WITH ANY SHOWERS THAT DEVELOP
TONIGHT THROUGH TUESDAY, PARTICULARLY ACROSS THE CENTRAL AND WESTERN
BASIN OF THE LAKE.
