As Cleveland braces for a shift from the old year's warmth to a new year's frigid embrace, the National Weather Service in Cleveland outlines a detailed forecast that sees a low-pressure system bringing a mixtape of weather phenomena to the area. Residents should expect rain transforming into snow as "a trough will set up over Lake Erie behind the low for Wednesday and remain through the weekend," per the NWS Cleveland report.
Today's low pressure over central Illinois is anticipated to bring a band of steady rainfall later this morning, becoming more "scattered" as the day progresses. "Have continued to mention a 100 percent chance of rain across the area," the NWS notes, perhaps preparing Ohioans for unavoidable wet conditions before the year's end. Tonight to bring a transition from the rain to wet snow, with snow accumulations expected to be more visible on grassy and elevated surfaces rather than roadways.
The weather shift is pronounced with "a strong surge of cold air" accompanying the cold front that will hit the area by Wednesday. Some areas, particularly Geauga County, OH and Erie and Crawford Counties, PA, are forecasted to experience significant lake effect snow events, promting the NWS to upgrade the Winter Storm Watch to a Lake Effect Snow Warning. These areas will likely encounter heavy snow squalls enhanced by "upslope flow in the higher elevation areas," adds the official NWS discussion.
In aviation, pilots can expect IFR conditions to become the norm as "IFR will be the expect ceiling across the region on the back side of the low pressure system and cold front with snow moving across the region," affecting visibility and flight schedules. Winds will also see a notable shift – starting easterly then veering to the northwest with gusts increasing up to 30 knots overnight, as stated in the NWS Cleveland aviation report.
Similarly, maritime conditions on Lake Erie will be far from calm as Small Craft Advisories have been issued in response to increasing northeast winds ahead of the low-pressure system. Following the low, a consistent west-northwest flow will maintain unsettled waters through the weekend. The Small Craft Advisory covers much of Lake Erie, differing expiration times depending on the location. Boaters in western nearshore waters can expect advisories until Thursday morning, while eastern waters should prepare for restrictions through Sunday, according to the NWS advisories' details.
