As we ready our coats and umbrellas for what's ahead, the National Weather Service in Cleveland has dropped the latest forecast, and it's a mixed bag for Ohioans. The low pressure dance concludes today, making room for high pressure to slide in from the southwest. This fleeting respite promises dry weather extending through Monday evening. But don't get too cozy just yet—another robust low pressure system is eyeing the Great Lakes region, ready to serve up impacts that'll stretch well into the week.
Today's transition period, a sort of meteorological intermission, presents a low-chance mix of rain and snow for those in NE OH and NW PA this afternoon. "Outside of that, the low pressure system and upper trough will pass to the east and high pressure will enter for the rest of the period, allowing for dry weather through Monday evening," the NWS forecast discussion outlines. Despite the sunnier outlook, though, a mighty system from the south plans to disrupt this calm with a rainy Tuesday, with precipitation ranging from 0.25 to 0.75 inches.
Wednesday is shaping up to be particularly noteworthy—with temperatures plummeting following a cold front, rain will give way to snow, and swiftly so. Expectations are for the white stuff to come in hard and fast for the lake-effect prone zones of NE OH and NW PA, which could prove challenging for Thanksgiving Eve travel. Be prepared for potential snow accumulation and "blustery" conditions post-frontal passage, a detail not to be disregarded when planning holiday commutes.
Lake effect snow is then poised to dominate the conversation through to Friday. Current forecasts harbor "increasing confidence in accumulating snowfall" in NE OH and NW PA, teased for both Thanksgiving and Black Friday. However, specifics regarding totals, rates, and impacts are still being ironed out. For mariners, it's a bit of a waiting game—strong post-cold front winds may flirt with gale force come Wednesday night through to Friday, conditions permitting. The NWS cautions, "This entire period from Wednesday through Friday will need a marine headline of some kind as hazardous conditions are expected." A brief, but chilly, calm is anticipated to follow on the heels of the holiday frenzy.
For aviators, clearer skies are on the radar with VFR conditions expected to hold until the new system arrives Monday night. NWS advised, "VFR is favored through Monday before non-VFR chances return Monday night through Wednesday." And for those on the ground, it seems the upshot is to enjoy the dry spell while it lasts, and brace for an eventful, possibly white, Turkey Day.
