Marine Weather and Tide Forecast for Akron, OH

NEAR TERM /THROUGH SUNDAY NIGHT/
Some light showers are present ahead of a cold front that is progressing southeast across the area and latest radar shows convective showers attempting to develop along the front.
Clearing across southeastern zones has allowed some surface- based instability to develop and there is still at least a small chance of one last round of convection within the next few hours before the front exits to the southeast this evening. If any storms do manage to develop, isolated instances of gusty winds and hail cannot be ruled out. With that being said, the best instability and higher risk of stronger storms will likely remain to the southeast of the CWA Have maintained high-end chance PoPs (around 50 percent) in locations that may see showers/storms through early this evening with PoPs quickly tapering off from 00Z onward as high pressure builds in behind the front. It's possible that showers/storms are a bit more hit or miss than anticipated, so PoPs may be tapered back further in the next update.

The break in precip will be short-lived and rain chances return Sunday night as the aforementioned front lifts north from the Ohio Valley as a warm front in response to a low ejecting from the Middle Mississippi Valley to the Upper Midwest. Isentropic ascent ahead of the warm front will allow PoPs to increase from southwest to northeast near or shortly after Midnight Sunday night. The best chances of precip will arrive after 12Z/8 AM Monday (see short term discussion below).

Tonight's lows will fall into the 40s in most spots, but portions of interior NW PA will likely dip into the upper 30s. Sunday's highs will likely reach the 50s and lower 60s with the warmest temps expected along and south of U.S. Route 30.
Northeast winds off of Lake Erie may keep temperatures across portions of northwestern Ohio in the upper 40s to lower 50s.
Sunday night's lows will be in the upper 40s to mid 50s, however locations downwind from Lake Erie will be in the cooler mid-40s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
Low pressure originating from the Central Plains will move north into the Upper Midwest during the day on Monday. This low will lift a warm front north across the Upper Ohio Valley early Monday allowing for some rain showers to develop during the daytime hours.
Southerly return flow will allow for temperatures to rise into the mid 70s. Dew points in the upper 50s to lower 60s coupled with diurnal heating should allow for enough instability to develop Monday afternoon and early evening to support isolated thunderstorms. Severe threat remains low given the weak instablilty but the wind field may support strong storms producing gusty winds and small hail. The low continues to lift north by Monday evening and will drag a cold front east Monday evening with PoPs decreasing through early Tuesday morning as high pressure enters from the west.
Tuesday will be dry under high pressure with forecast highs in the 60s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
High pressure gradually builds to the east on Wednesday while a warm front lifts east across Lake Erie. Models begin to diverge by Thursday as both the ECMWF and Canadian have the upper level ridge persisting through Thursday evening while the GFS lifts a shortwave across the region. Have maintained low PoPs Thursday afternoon onward with PoPs increasing on Friday given the better forcing aloft. High pressure will begin to build overhead from the north, but rain chances may linger through the first half of the weekend.

High temperatures are forecasted to rise into the low/mid 70s through Friday with slightly cooler highs in the 60s expected on Saturday.

AVIATION /18Z Saturday THROUGH Thursday/
Cold front is slowly pushing southeast across the area this afternoon. The first couple rounds of convection have exited the area and some scattered showers will likely linger over the region through this afternoon. There will generally be pockets of low-end VFR and MVFR ceilings, although there is some clearing on satellite so ceilings may become a bit more optimistic than currently forecast. The clearing may result in a bit of destabilization through early evening and some CAMs are hinting at another wave of convection lifting northeast into the region late this afternoon into early this evening. This round of showers/storms will either stay south of the CWA or scrape southeastern terminals and have added PROB30 groups for terminals that have at least a low-end chance of thunderstorms prior to ~00Z.

Visibility guidance suggests that a plume of fog and lower stratus could push off of Lake Erie and into NW PA late this afternoon into this evening. KERI may experience a period of IFR ceilings and as low as LIFR visibility between 22Z and 01Z.

High pressure will quickly build into the region as the cold front pushes south of the area tonight. Ceilings will gradually improve behind the front and all terminals will have VFR ceilings by no later than 09Z. VFR will prevail through the remainder of the TAF period.

West/northwest winds to 10 to 15 knots with periodic gusts to 20 to 25 knots will diminish below 10 knots at around 00Z and then gradually veer to the northeast overnight. Winds will likely increase to 6 to 12 knots at western terminals Sunday morning.

Outlook...Periodic rain showers and thunderstorms with non-VFR possible Sunday night through Monday night.

MARINE
Westerly winds 10-15 knots this afternoon will turn northerly behind a cold front by tonight. Northerly winds will gradually becoming northeasterly to easterly during the day on Sunday as high pressure builds overhead from the north. As the high exits to the east, a warm front will lift north towards the lake Sunday night into Monday morning which will shift winds southerly while increasing to 15-20 knots. A Small Craft Advisory may be needed for these higher winds on Monday morning and afternoon. Winds turn southwesterly behind a cold front Monday night and Tuesday while decreasing to 10-15 knots as another area of high pressure builds overhead.
