DISCUSSION
KEY MESSAGE 1...
POST-FRONTAL WIDESPREAD RAIN WILL GRADUALLY EXIT EAST OF THE
AREA LATER THIS MORNING, WITH AN ADDITIONAL 0.25 TO 0.50 INCHES
OF RAIN EXPECTED, MAINLY EAST OF THE I-71 CORRIDOR. STARTING TO
SEE SOME MINOR RIVER RISES, BUT NOTHING TOO SIGNIFICANT THUS
FAR. A COOLER AIR MASS WILL ARRIVE INTO THE REGION LATER TODAY,
CHARACTERIZED BY 850 MB TEMPERATURES FALLING BETWEEN 0 TO -2C,
WHICH WILL DROP OVERNIGHT LOWS INTO THE MID TO UPPER 30S. AT
THIS TIME, THE HIGHEST CONFIDENCE FOR FROST TO DEVELOP TONIGHT WILL
GENERALLY BE WEST OF THE I-71 CORRIDOR WHERE CLOUD COVER SHOULD
DIMINISH MORE QUICKLY VS FURTHER EAST. ANOTHER CHANCE FOR FROST
CONDITIONS IS POSSIBLE THURSDAY NIGHT, THOUGH A WEAK LOW
PRESSURE SYSTEM MOVING THROUGH THE AREA COULD INTRODUCE CLOUD
AND/OR RAIN CHANCES AND LIMIT THE OVERALL POTENTIAL.
KEY MESSAGE 2...
MORE WIDESPREAD RAIN CHANCES WILL RETURN FRIDAY NIGHT INTO
SATURDAY AS A LOW PRESSURE SYSTEM MOVES EAST THROUGH THE LOWER
GREAT LAKES REGION. THERE EXISTS SOME UNCERTAINTY ON THE AXIS OF
HEAVIER RAINFALL AND THE OVERALL EVOLUTION OF THE SYSTEM,
THOUGH THE AREAS WHERE RAIN OCCURS CAN GENERALLY EXPECT TOTAL
AMOUNTS BETWEEN 0.25 AND 0.50 INCHES. A STRONGER LOW PRESSURE
SYSTEM AND ASSOCIATED COLD FRONT WILL MOVE EAST THROUGH THE
REGION ON SUNDAY, BRINGING WIDESPREAD RAIN AND PERHAPS SOME
EMBEDDED THUNDERSTORMS ACROSS THE AREA. TOTAL RAINFALL AMOUNTS
WITH THIS SYSTEM, HAVE THE POTENTIAL TO BE SLIGHTLY HIGHER THAN
THE FRIDAY SYSTEM GIVEN THE MORE CONVECTIVE ELEMENTS INVOLVED.
ANOTHER COOL AIR MASS WILL ARRIVE BEHIND THE COLD FRONT EARLY
NEXT WEEK, WITH LOW TEMPERATURES FALLING INTO THE 40S OR UPPER
30S, ESPECIALLY MONDAY NIGHT INTO EARLY TUESDAY MORNING. THE
ACTIVE PATTERN IS FAVORED TO CONTINUE TOWARDS MID-WEEK AS A
THIRD LOW PRESSURE SYSTEM APPEARS TO IMPACT THE LOWER GREAT
LAKES REGION ON WEDNESDAY.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
THE LAST OF THE RAIN WILL END AT KYNG AND KERI OVER THE NEXT 1
TO 2 HOURS, WITH IFR/LIFR CIGS THERE IMPROVING TO MVFR.
OTHERWISE, ALL TERMINALS WILL BE PREVAILING VFR BY MID MORNING
AS DRIER AIR WORKS INTO THE REGION. VFR IS THEN EXPECTED
THROUGH TONIGHT AS HIGH PRESSURE BUILDS OVER THE GREAT LAKES.
NW WINDS WILL AVERAGE 5-10 KNOTS LATER THIS MORNING INTO THIS
AFTERNOON, BACKING TO MORE WNW BY THIS EVENING AND TONIGHT.
OUTLOOK...PERIODIC SHOWERS AND THUNDERSTORMS WITH NON-VFR ARE
EXPECTED FRIDAY THROUGH SUNDAY.
MARINE
MAINLY QUIET CONDITIONS WILL CONTINUE ON LAKE ERIE THROUGH THE
WEEKEND AS PRESSURE GRADIENTS WILL BE OVERALL WEAK, SUPPORTING
LIGHT WINDS MOST OF THE TIME. LIGHT AND VARIABLE WINDS EARLY
THIS MORNING WILL BECOME NW TO WNW AT 5-15 KNOTS THIS AFTERNOON
THROUGH TONIGHT BEFORE BACKING TO W AT 5-15 KNOTS THURSDAY. SW
WINDS WILL AVERAGE 10-15 KNOTS THURSDAY NIGHT AND FRIDAY, WITH
SW WINDS EXPECTED TO DOMINATE THROUGH SATURDAY WITH SPEEDS
RANGING FROM 5 TO 15 KNOTS. WINDS SHOULD FINALLY TURN N BEHIND A
COLD FRONT SUNDAY AND DECREASE TO 5-10 KNOTS. NO MARINE HEADLINES
