The National Weather Service in Cleveland has updated its area forecast, noting that residents downwind of the Great Lakes, particularly in Northeast Ohio and Northwest Pennsylvania, can expect continued lake-effect rain today. The detailed report, recently shared by the NWS Cleveland, indicates that higher precipitation totals of 1-3 inches may occur in the primary snowbelt, which includes the counties of Cuyahoga, Lake, Geauga, and Ashtabula in Ohio, as well as Erie/Crawford in Pennsylvania. Thunderstorms could also be on the radar—quite literally—for some areas.
The forecast has made it clear that while the majority of the rain will be confined to areas north and east of Lorain to Youngstown, other regions might see some residual showers carried over from Lake Michigan. The National Weather Service urges caution, as isolated minor flooding could be a concern in places where higher quantities of rain fall, particularly in low-lying areas or on roads obstructed by fallen leaves in storm drains.
Temperatures across the region are expected to dip, according to the forecast communicated, with daytime highs in the low 50s and overnight lows ranging from the low 40s to mid-30s. A Frost Advisory was under consideration but has not been issued due to models suggesting that low clouds and enough of a pressure gradient might prevent frost from forming, even if temperatures hit the 33-36 degree range.
Looking ahead, the near-term forecast indicates that lake effect rain will persist through Friday night but should lessen and shift east as high pressure makes its way in. Frost formation is likely to form overnight/early morning through the weekend, with frost advisories or freeze warnings potentially necessary. Uncertainty remains, however, about the weather outlook for Northeast Ohio and Northwest Pennsylvania, where lingering low-level clouds could limit the frost's reach. Some model guidance has moisture becoming trapped underneath a temperature inversion, which could greatly limit radiational cooling and subsequent frost potential, the NWS detailed in their report.
In terms of aviation and marine impact, the NWS Cleveland predicts that trough conditions over Lake Erie will lead to periods of scattered showers and lake-enhanced rain, affecting visibility at local airports, with a Small Craft Advisory in effect for several areas along the lake through at least Friday afternoon.
