Cleveland is experiencing a winter wallop as a low-pressure system and its cold front exit, yielding a strengthening trough that will hover over Lake Erie through the weekend. According to the National Weather Service, Northeast Ohio and Northwest Pennsylvania are already seeing the changeover from rain to snow, particularly in areas above 1000 feet. Although some spots accumulate measurable snow, others, especially those near Lake Erie or lower elevations, still experience rain as the dominant form of precipitation due to mid-30s temperatures that inhibit snow from sticking.
The NWS describes a transition to all snow across the region by early afternoon, with Geauga County, Ohio, and interior portions of Northwest Pennsylvania expected to see the best snowfall accumulations. Yet, there's a catch—areas like Mansfield and around Interstate 71 could see up to an inch of snow, hindered by limited snow growth aloft. The near-term forecast indicates a brief lull in snow intensity later this morning into early afternoon for the snow belt as conditions reorganize for the main lake effect snow event.
Meanwhile, as the upper trough absorbs into the broader northeast trough, the area braces for a renewed burst of cooler air and a saturated snow generation zone. National Weather Service notes, "More importantly, this will bring in some cooler air aloft and a saturated DGZ about 5 to 7 kft above the surface that will build into a more traditional lake effect with help from upstream lake connections." Initial northwest-oriented multibands are expected to target the Northeast Ohio and Northwest Pennsylvania snow belt. Furthermore, a backing flow through Thursday could provide a brief respite from the snow for most of Ohio, sparing only Erie County, PA, by the end of the period.
The NWS discussions maintain current winter weather advisories and warn of potentially shrinking Northeast Ohio's 8" snow contour. Conditions are flirting with the issuance of an advisory for northern Summit, Portage, and Trumbull Counties, with accumulations possibly reaching up to 5 inches by Thursday evening. Nevertheless, those specific locations are being spared a formal headline for now.
Looking ahead, the short-term outlook isn't exactly heartwarming. The snowy blanket over the region might just get thicker as we head into the weekend. The forecast suggests that with light west-southwest flow, some lake effect will likely still be at the least clip locations from Lake County up through northern Ashtabula County and portions of Erie County, PA, Thursday night." The lake effect is seen as marginal until Friday, when a low-amplitude shortwave could introduce a spell of light snow across much of the forecast area. Conditions will deteriorate further with cold air influx, prompting potential lake effect snow rates of 0.5 to 1.5 inches per hour. Are the current snow warnings for Northwest PA likely to endure, affecting the Ohio snowbelt? The impending weather certainly seems to underscore that possibility.
