DISCUSSION
KEY MESSAGE 1...
THE REMNANT LOW ASSOCIATED WITH ISAIAS HAS TAKEN A TRACK THAT
IS FARTHER TO THE EAST THAN PREVIOUSLY FORECAST, THROUGH EASTERN
TENNESSEE TOWARDS THE CENTRAL APPALACHIANS. THE AXIS OF DEEP
MOISTURE IS TO THE EAST OF THE TRACK AND IS PRIMARILY FOCUSED
ACROSS WEST VIRGINIA AND PENNSYLVANIA WHICH IS WHERE THE HEAVIER
RAIN IS GOING TO OCCUR. RAINFALL OVERNIGHT HAS BEEN QUITE
LIGHT, WITH A QUARTER INCH OR LESS AND MANY AREAS RECEIVING A
TENTH OF AN INCH OR LESS. AREAS LOCATED EAST OF I-77 COULD STILL
SEE AN ADDITIONAL HALF INCH OF RAIN WHILE AMOUNTS ARE GOING TO
RANGE FROM 0.10-0.25 ELSEWHERE. THE UPPER LEVEL CLOSED LOW IS
DISPLACED TO THE WEST OF THE SURFACE LOW AND WILL TRACK
NORTHEAST THROUGH THE OHIO VALLEY TODAY. THIS WILL MAINTAIN SOME
SHOWER ACTIVITY BUT DRY AIR IN THE MID LEVELS WILL BE A
LIMITING FACTOR AND CUT-BACK SIGNIFICANTLY ON RAINFALL AMOUNTS.
ALSO REMOVED THUNDER FOR TODAY AS WE HAVE SEEN ONLY ONE STRIKE
SOUTH OF OUR AREA OVERNIGHT. A MINIMAL AMOUNT OF ELEVATED
INSTABILITY REMAINS IN OUR SOUTHERN COUNTIES BUT THE BETTER
FORCING CONTINUES TO SHIFT EAST.
SOME LOCATIONS ACROSS NORTHEAST OHIO AND NORTHWEST PENNSYLVANIA
ARE STARTING TO SEE WINDS GUSTING AROUND 20 MPH WHERE THE
GRADIENT IS THE TIGHTENING UP. WE STILL BELIEVE A FEW STRONGER
GUSTS COULD OCCUR FOR NORTHERN PORTIONS OF ERIE PENNSYLVANIA
WHERE THE SOUTHEASTERLY WIND DIRECTION IS FAVORABLE FOR ENHANCED
DOWNSLOPING. GUSTS OF 30-40 MPH REMAIN POSSIBLE THROUGH MID
MORNING. ABUNDANT CLOUD COVER IS EXPECTED TODAY AND TEMPERATURES
WILL PEAK IN THE 60S.
KEY MESSAGE 2...
AN UPPER LEVEL RIDGE QUICKLY BUILDS NORTH BEHIND THE DEPARTING
TROUGH ON MONDAY. AT THE SURFACE, A RIDGE WILL BUILD EAST ACROSS THE
AREA WITH SOUTHWESTERLY WINDS AND WARM ADVECTION KICKING IN
ACROSS NORTHWEST OHIO DURING THE AFTERNOON. HIGHS ON MONDAY
RANGE FROM ABOUT 70 IN THE EAST TO 80 IN THE WEST. THE
ANOMALOUSLY WARM AIRMASS AIRMASS WITH 850MB TEMPERATURES OF
NEARLY 20C WILL BE IN PLACE ON TUESDAY AHEAD OF A COLD FRONT
SETTLING SOUTH ACROSS THE REGION. HIGHS ON TUESDAY MAY TIE OR
SURPASS MULTIPLE RECORDS ACROSS NORTHWEST AND NORTH CENTRAL
OHIO. SEE THE CLIMATE SECTION BELOW FOR DETAILS.
CHANCES OF RAIN HAVE SLOWED DOWN ON TUESDAY WITH A SLIGHT CHANCE
ACROSS LAKE ERIE TUESDAY MORNING AND THEN PUSHING INLAND LATE
TUESDAY AS A SHORTWAVE MOVES THROUGH THE FLOW ALOFT AND PUSHES A
COLD FRONT SOUTH OF LAKE ERIE LATE AFTERNOON AND EVENING.
CHANCES OF THUNDERSTORMS LOOK FOCUSED ACROSS NORTHEAST OHIO AND
NORTHWEST PENNSYLVANIA. SOME MINIMAL INSTABILITY IS FORECAST TO
DEVELOP AHEAD OF THE FRONT WITH DEWPOINTS IN THE LOWER 60S. MAY
NEED TO KEEP AN EYE ON ANY THUNDERSTORMS THAT CAN DEVELOP GIVEN
A STRONGER WIND FIELD WITH SHEAR IN THE 0-6KM LAYER OF 45-55
KNOTS.
KEY MESSAGE 3...
BY LATE THIS WEEK, MODELS ARE IN AGREEMENT THAT A STRONG TROUGH WILL
DROP SOUTH OUT OF CANADA USHERING IN THE COLDEST AIR OF THE SEASON.
THE FRONT LOOKS TO ARRIVE ON FRIDAY WITH COLD AIR FILTERING INTO THE
REGION THROUGH SATURDAY. THERE ARE SOME NOTEWORTHY DIFFERENCES IN
THE LONG RANGE PATTERN BY THE WEEKEND AS THE ECMWF DOES NOT PHASE
THE CANADIAN TROUGH WITH AN UPPER LEVEL LOW MOVING OUT OF THE ROCKY
MOUNTAINS AND IS MORE PROGRESSIVE WITH THE COLDER AIR QUICKLY
SHIFTING EAST. THE 00Z GFS AND CANADIAN BOTH INDICATE THERE WILL BE
PHASING WITH THE UPPER LOW WHICH RESULTS IN A SLOWER TROUGH AND
PERHAPS LAKE EFFECT PRECIPITATION. WILL NEED TO MONITOR TRENDS AS
LARGE SPREADS CURRENTLY EXIST IN TEMPERATURES BASED ON TIMING. IT IS
POSSIBLE THAT WE COULD SEE FROST AND FREEZE CONDITIONS NEXT WEEKEND,
ESPECIALLY IF HIGH PRESSURE ENDS UP OVERHEAD ON SATURDAY NIGHT.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
MVFR AND IFR CEILINGS HAVE MOVED IN FROM THE SOUTH THIS EARLY
THIS MORNING. CEILINGS WILL BECOME IFR AT ALL TERMINALS BY MID
MORNING AND PERSIST THROUGH THE TAF PERIOD. SCATTERED RAIN
SHOWERS ARE EXPECTED FROM KMFD EASTWARD AND WILL TAPER OFF WEST
TO EAST THROUGH THE AFTERNOON. LINGERING DRIZZLE AND MIST MAY
LOWER VISIBILITY THIS EVENING. AFTER 06Z TOMORROW, PATCHY FOG
IS POSSIBLE FOR KMFD, KTOL, AND KFDY THOUGH WILL BE CONDITIONAL
ON HOW QUICKLY CEILINGS CLEAR OUT. CONFIDENCE IS LOW IN
VISIBILITY LESS THAN 2SM IMPACTING TERMINALS.
WINDS WILL BE OUT OF THE EAST, 080-130, AT 8-13 KNOTS ACROSS
THE REGION INTO THE MORNING BEFORE WEAKENING TO AROUND 5-10
KNOTS. KERI WILL HAVE A MORE OF A SOUTHEASTERLY, 130-150, WIND
AND WITH DOWNSLOPING, COULD SEE GUSTS UPWARDS OF 20 KNOTS
THROUGH 17Z. WINDS WILL GRADUALLY BACK TO BE OUT OF THE
NORTHEAST, 020-050, DURING THIS AFTERNOON AND REMAIN 5-10 KNOTS.
AFTER 00Z, WINDS WILL SHIFT TO BE MORE NORTHWESTERLY, 310-340,
AND WEAKEN TO LESS THAN 5 KNOTS.
OUTLOOK...NON-VFR EXPECTED IN LOW CEILINGS SUNDAY NIGHT INTO
MONDAY, WITH IMPROVING CONDITIONS FROM WEST TO EAST THROUGHOUT
MONDAY. NON-VFR POSSIBLE TUESDAY AND WEDNESDAY IN
SHOWERS/THUNDERSTORMS ASSOCIATED WITH A COLD FRONT.
MARINE
SOUTHEAST WINDS ARE STARTING TO INCREASE IN THE NEARSHORE WATERS
FROM AVON, OH TO RIPLEY, NEW YORK WITH SPEEDS OF 15-25 KNOTS. THE
WINDOW OF STRONGER WINDS WILL BE SHORT LIVED AND EXPECT TO BE ABLE
TO LET THE SMALL CRAFT ADVISORY EXPIRE AS PLANNED AT 8 AM THIS
MORNING. WINDS SHIFT AROUND TO THE NORTHEAST LATER TODAY BUT ARE
EXPECTED TO GENERALLY BE LIGHT.
TWO COLD FRONT ARE EXPECTED TO CROSS LAKE ERIE THIS WEEK WITH
IMPACTFUL CONDITIONS. THE FIRST IS ON TUESDAY EVENING WHEN A COLD
FRONT WITH WINDS OF 15-20 KNOTS SHIFTS ONSHORE. WAVES OF 2 TO 5 FEET
WILL BE POSSIBLE FOR A FEW HOURS BEHIND THE FRONT ON TUESDAY NIGHT
AND A SMALL CRAFT ADVISORY MAY BE NEEDED EAST OF GENEVA-ON-THE-LAKE.
BY LATE THIS WEEK, A MUCH STRONGER COLD FRONT LOOKS TO CROSS LAKE
ERIE IN THE FRIDAY TIME FRAME. WINDS ARE FORECAST TO REACH 30 KNOTS
WITH POTENTIAL FOR A GALE EVENT. THE STRENGTH AND TRACK OF THIS LATE
WEEK SYSTEM WILL BE MONITORED OVER THE COMING DAYS.
