GRADUALLY DIMINISH FROM WEST TO EAST THROUGH SUNDAY EVENING.
GENERALLY ANTICIPATE COVERAGE TO REMAIN ISOLATED TO SCATTERED
DURING PERIODS OF SHOWERS AND THUNDERSTORMS THIS WEEKEND. ANY
SHOWERS AND STORMS THAT OCCUR WILL BE CAPABLE OF PRODUCING HEAVY
RAIN AS PWAT VALUES RISE TO 1.75-2.00 INCHES SATURDAY INTO
SUNDAY.

VFR CONDITIONS ARE EXPECTED THROUGH MUCH OF THE TAF PERIOD WITH
HIGH PRESSURE ACROSS THE REGION. WINDS WILL CONTINUE TO FAVOR A

SHOULD BE GENERALLY CLEAR BUT SOME AFTERNOON CUMULUS MAY
DEVELOP IN NW OHIO. AS HIGH PRESSURE MOVES EAST, WINDS WILL BACK
TO THE SOUTHWEST FOR FRIDAY MORNING. SOME MVFR VISIBILITY MAY BE
POSSIBLE AT KCAK AND KYNG ON FRIDAY MORNING.

LIGHT NORTHWEST FLOW WILL REMAIN OVER THE LAKE TODAY AND WILL
SHIFT TO THE SOUTH ON FRIDAY WITH HIGH PRESSURE MOVING EAST. FOR
THE WEEKEND, A LOW PRESSURE SYSTEM WILL APPROACH FROM THE WEST

BRING THE CHANCE OF SHOWERS AND STORMS TO THE REGION. EAST TO
NORTHEAST FLOW WILL BE FAVORED ON SATURDAY AND WAVES 1 TO 2 FT
WILL BE POSSIBLE AROUND THE LAKE ERIE ISLANDS REGION. WINDS WILL
INCREASE A BIT FOR SUNDAY AND BECOME MORE NORTHERLY AND WAVES 1
