As the National Weather Service in Cleveland reports, high pressure is providing a blanket of stability over the region today. But don't get too cozy—a low-pressure system is on its heels, looking to stir things up by Friday. This system is expected to introduce a cold front sweeping through the area by late Friday, bringing instability before another aura of high-pressure sets in for next week.
A chill continues to grip Northeast Ohio and Northwest Pennsylvania post cold frontal passage, the low-level moisture clinging just enough to keep lake-effect clouds in play. But don't look for raindrops; they're not on this morning's guest list. The gray will hang through much of the morning, a stubborn guest that eventually gets nudged out as a ridge from the west muscles in by afternoon. "Lake-effect cloud cover may remain through much of the morning," the National Weather Service explains. Yet, sunshine isn't distant, particularly for those in Northwest and North-Central Ohio, where daytime highs could tickle the lower 60s.
Looking to Friday, keep the umbrellas at arm's reach if you're near the I-75 corridor in Northwest Ohio — that's where the first raindrops could fall come morning, leftovers from nocturnal convective activity further west. In the afternoon, showers may become more democratic, spreading along and east of the I-71 corridor as the cold front looms closer. Despite the looming gloom, temperatures are tipped to nestle into the 60s before the front's arrival.
Weekend warriors brace for a temperature tumble as the cold front exits the stage last Friday night, with a residual surface trough potentially squeezing out a few more showers into Saturday, particularly in the snowbelt. The National Weather Service notes, "These areas may see a few lingering showers into Saturday morning," but dry air should curb the precipitation by the afternoon. High pressure's return ushers in dry conditions and more extraordinary air – daytime highs restrained to the 50s, with nighttime lows dipping into the 30s over the weekend.
Skipping ahead to next week, high-pressure teams up with an upper-level ridge, forming a defensive line against precipitation. The highlight is a warming trend as temperatures are projected to leap above the norms for late October, with highs by Wednesday potentially flirting with the upper 70s. "The biggest story with this period will be the dominant southerly flow and increased WAA resulting in temperatures again surging into well above normal temperatures for this time of year," the National Weather Service prognosticates. Nighttime temperatures, meanwhile, stick to a milder script, lounging in the upper 50s and possibly low 60s.
