The National Weather Service in Cleveland has reported a significant weather shift impacting Ohio and parts of Pennsylvania as low-pressure systems and high-pressure buildups influence the region's forecast. According to the National Weather Service, a low-pressure system hovering over lower Michigan is making its way east to Lake Ontario, bringing a mix of showers and cooler temperatures, especially noticed in areas near Lake Erie. A high pressure is expected to build over the region from Tuesday through Thursday, likely providing clearer skies and a respite from the dreary conditions.
Cooler weather and light precipitation are the general outlook for the start of the week. As for temperatures, they're tapering off into an almost fall-like feel, especially in Northeast Ohio and Northwest Pennsylvania, where highs may struggle to escape the 60s. "For most of the region, QPF amounts will be light with mean QPF amounts of around 0.1-0.25", though locally higher amounts of up to 0.5" are possible in Northeast Ohio and Northwest Pennsylvania," said the National Weather Service. The area is also subject to potential lake-enhanced rain showers as a result of the moisture wrapping around the departing upper-low.
Diving into the short term, conditions are set to improve marginally. The dreaded cold front that has been lingering is supposed to give way to clearer skies due to the high-pressure system moving southeastward. Overnight temperatures are forecasted to dip into the 50s starting Tuesday, with daytime highs creeping only into the 60s and 70s for much of Northern Ohio and Pennsylvania. Wednesday night might offer even cooler conditions, with lows again in the upper 40s to mid-50s.
As the week progresses, however, temperatures are expected to climb back to more seasonable figures. "The ridge above aloft is expected to continue to build gradually from the north-central United States and vicinity during this period," indicates the National Weather Service discussion. By Saturday, the region can look forward to the 80s, with overnight lows stabilizing in the mid-50s to mid-60s. It's a nod to the proverbial light at the end of the wet and cool tunnel that's defined the region's weather pattern of late.
Marine conditions on Lake Erie have necessitated small craft advisories and beach hazard statements. The discussion notes by NWS, "Waterspouts are possible through Monday, especially along the cold front and post-front surface trough axes." Boaters should anticipate winds from 10 to 25 knots and waves building up to 3 to 6 feet, particularly troublesome in the western and central parts of the lake. These advisories are in effect until Tuesday evening in certain areas. Conditions on Lake Erie should mollify by Wednesday morning, offering a smoother sail for mariners.
