Cleveland’s weather patterns are taking a twist as forecasters predict a swing from showers to snow by the Thanksgiving holiday. According to the National Weather Service of Cleveland, the low pressure that drenched the region will be moving out, paving the way for drier conditions and cooler temperatures throughout Saturday.
A "surface ridge will be able to build into the region today behind the surface low and dry conditions will be expected," the NWS report stated. The region can anticipate more settled weather with temperatures hovering steadily in the 40s, a noticeable dip from the norm. By Sunday, however, an upper trough and a northeastern low pressure system may bring a light rain and snow mix to the fringes of the area, especially favoring areas further east in Northwestern Pennsylvania.
Looking further ahead, "high pressure will return to the region for Monday," which will allow temperatures to bounce back toward average highs in the 50s. But the respite will be short-lived as a strong low pressure system is expected to target the Great Lakes on Tuesday and Wednesday, bringing with it widespread rainfall with estimates in the 0.25-0.75 inch range, according to NWS Cleveland.
As the holiday approaches, temperatures look set to plummet once more, "with 850 mb temperatures returning to -10 C by Thursday," the NWS points out. This could mean a shift back to snowy conditions, particularly affecting Northeast Ohio and Northwest Pennsylvania. The expected lake effect snow is typical of the region, but exact forecasts and band placements remain uncertain at this time. Yet, "it is worthwhile to place more likely PoPs into the forecast for Thursday night through Friday for far NE OH and NW PA," the forecast continues. Travelers and residents alike are advised to monitor weather updates as they plan holiday itineraries.
Marine conditions on Lake Erie will also feel the changing weather patterns, with northerly winds shifting to southwesterly and building to 4-6 feet waves on Sunday. A Small Craft Advisory is likely in effect for Sunday, and mariners should prepare for increased westerly winds of 20-30 knots post-Tuesday's cold front. "This will once again make marine conditions across Lake Erie hazardous," warns the NWS, highlighting the importance for those venturing onto the lake to heed advisories and stay alert for potential low water levels and elevated winds and waves throughout the week.
