The weather in Cleveland is taking a turn as a low pressure system from the southwest heads northeast, aiming at New England by Friday. This update, courtesy of the National Weather Service in Cleveland OH, details a subsequent trough that'll linger around the Great Lakes through the upcoming weekend. A brief high pressure respite may grace Sunday before another system makes its mark early next week.
The area's near-term forecast includes mid to upper 50s for today's highs, quite the normal for this time of year, but prepare for a shift this evening. "Scattered light rain" is expected to roll in from the south—particularly along and south of U.S. Route 30—owing to a mix of isentropic ascent aloft and Gulf moisture, the National Weather Service in Cleveland reports. Overnight, look for lows spanning the upper 30s to upper 40s, inching towards daytime highs in the cooler upper 40s to lower 50s by Thursday. Seize the milder temps while they last because heavy, persistent rain is lined up for Wednesday night through Thursday.
Severe weather enthusiasts, keep an eye out; the lake's impact could intensify conditions as lake-enhanced precipitation joins the fray. "During Thursday night, lake-enhanced or effect rain should transition to pure lake-effect rain, heavy at times," states the NWS Cleveland. If you’re near the lakeshore, particularly from Lorain County to Erie County, PA, brace for wind gusts that may hit 40 to 50 mph as the forecast evolves.
Looking into the weekend, the wet saga continues with cyclonic flows stirring up isolated to scattered showers from Friday to Saturday night. Breaks in the precipitation are possible, particularly as a ridge builds and crests eastward over northern Ohio and Northwest PA, but the primary snow belt could still see rain squeezing every last drop from the clouds. "LER, primarily light in intensity, should stream generally E`ward over/downwind of Lake Erie," the NWS official discussion notes, though rain is not expected to mix with wet snow in the higher elevations during this short-term period.
