Marine Weather and Tide Forecast for Port Clinton, OH

NEAR TERM /THROUGH MONDAY/
Stationary front remains stalled south of the forecast area as an area of high pressure builds in from the north. Light winds and saturated low levels have allowed for patchy fog to develop across southeastern zones early this morning. Fog is expected to diminish after dawn this morning. Most of the area should remain dry through tonight though some isolated showers may clip the southern tier of the forecast area this afternoon. The front will gradually lift back north on Monday afternoon with isolated to scattered showers Monday afternoon and evening across the southern half of the forecast area. PWATs remain high and mean layer flow remains slow so any shower/thunderstorm will be capable of heavy rainfall and localized flooding on Monday.
Patchy fog/low stratus will be possible again tonight into early Monday morning across inland locations. Afternoon highs today rise into the mid to upper 70s with overnight lows settling in the lower 60s. A few degrees warmer on Monday with highs in the upper 70s to lower 80s, highest temperatures expected across Northwest Ohio.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/
The short term forecast period will favor a very warm and unsettled weather pattern with a quasi-zonal mid level flow. The recent stationary frontal boundary that has been over the Ohio Valley will lift northward as a warm front Monday night into Tuesday. At the same time, a weak mid level disturbance in the 500 mb flow will track slowly from west to east across the Upper Ohio Valley on Tuesday. Scattered showers and thunderstorms will be likely on Tuesday with the highest POPs across our central and northeast Ohio counties as well as northwest Pennsylvania. Lower POPs will favor northwest Ohio on Tuesday. Most of the convection Tuesday will be diurnally driven. High temperatures on Tuesday will range from the upper 70s over NWPA and lower 80s over NEOH. The warmest temperatures will be over NWOH on Tuesday in the middle 80s.

A shortwave trough will track through the Upper Midwest into the Great Lakes region Wednesday into Wednesday night. The timing is still a little uncertain for the mid-week system and will be key on how strong the convection may be for our area. A slow moving cold front will slide southward through the Great Lakes region into the Upper Ohio Valley late Wednesday into Wednesday night. Scattered showers and thunderstorms will be likely ahead of this front across the Upper Ohio Valley. We may have to monitor trends and timing for the potential of some stronger convection potentially as well as a localized heavy rainfall threat. High temperatures will be in the lower to middle 80s ahead of the front Wednesday.

LONG TERM /THURSDAY THROUGH SATURDAY/
The shortwave trough will track across the southern Great Lakes and Upper Ohio Valley region on Thursday dragging a cold front through the area. Scattered showers and thunderstorms will once again be likely with the highest POPs across the eastern CWA High pressure will build in by Friday with drier and seasonably warm temperatures for the mid to end of June. By the weekend, the overall weather pattern will shift to a large ridge across the southern CONUS. The Great Lakes and Upper Ohio Valley region will be in a northwest flow around the edge of this upper level ridge. We may have to watch for small disturbances coming down through the northwest flow around this growing upper level ridge. The ridge will expand into the Lower Ohio Valley by the end of the weekend with very warm temperatures and slight chance for POPs.

AVIATION /06Z Sunday THROUGH Thursday/
Generally VFR and clear skies across the majority of terminals with some MVFR ceilings at inland terminals along and east of I-71 (KMFD/KCAK/KYNG). Highest confidence in low stratus (IFR to LIFR) will be at KMFD/KCAK/KYNG beginning around 08Z before improving to MVFR around 13Z. Any lingering MVFR ceilings will lift to VFR in the afternoon. Showers should stay south of terminals but can't rule out a stray shower clipping southern TAF sites (KCAK/KYNG) in the afternoon.

Easterly to northeasterly winds 5-10 knots persist through the TAF period. Light and variable winds will occur across inland TAF sites through the morning.

Outlook...Non-VFR possible in patchy fog and lower ceilings early Monday morning. Non-VFR likely with periodic showers and thunderstorms Monday through Thursday, best chance Tuesday afternoon and Wednesday into Thursday.

MARINE
A frontal boundary has become nearly stationary south of the lake across central and southern Ohio. Northeast winds 10 to 18 knots will be around today into tonight. We will have to monitor trends for a possible marginal Small Craft Advisory conditions today with waves 2 to 4 feet. At the very least, there will be a moderate risk for rip currents for much of our lakeshore area today. Northeast winds will continue Monday 5 to 10 knots. Winds will become south- southwest 5 to 15 knots by Tuesday when a warm front pushes northward across the lake. Southerly southwesterly winds will continue Wednesday and Thursday 10 to 20 knots.
