The National Weather Service in Cleveland has had its hands full, tracking a procession of weather patterns expected to hit northern Ohio. A cold front made its exit early Monday morning, and residents were treated to a quiet but cool Tuesday as high pressure took up residence over the region. According to the NWS Cleveland's area forecast discussion, temperatures dipped into the upper 20s to lower 30s overnight, while Tuesday stayed cooler with highs creeping into the mid to upper 40s, though those near Lake Erie found themselves huddling closer in response to chillier lower 40s, thanks to a northerly breeze.
Don’t let the brief return to chilly weather fool you, though. The reprieve is set to dramatically end mid-week as another low-pressure system barrels into the Upper Midwest. Wednesday is going to quickly warm up as a warm front lifts north, bringing potential complications with it. "Morning and midday rain showers will be likely with the warm front lifting through," warns the NWS discussion. They also highlighted the potential for "isolated, elevated thunderstorms," which could make for a tempestuous Wednesday morning.
The warmer air isn't merely for comfort. It's carrying energy that could fuel severe weather and thunderstorms late Wednesday into Thursday, NWS Cleveland cautioned, with storm threats potentially escalating in Northwestern Ohio. Specific details concretize the risks, as the Science and Operations Officer (SOO) briefed, "Damaging wind gusts, large hail, and an isolated tornado threat will be the severe hazards Wednesday evening." The mention of effective shear reaching 60 to 80 knots spells out concerns quite starkly; those in the area should ensure that the situation is monitored closely.
By Thursday, a cold front is expected to linger like a specter near central Ohio, prompting a continuous likelihood of precipitation. This increases the chance of heavier rainfall totals across the area, which could raise flooding concerns. With the outlook extending into the weekend, the front may be virtually stationary, with further rounds of rain adding up to not-so-insignificant totals. "Rainfall totals may add up from the mid week through the weekend to cause some flooding and hydro concerns on our local rivers," the NWS observation cautioned. The subsequent cool-down will come as a shard of arctic air plunges through the Great Lakes and Ohio Valley.
Amidst the shifts in winds and looming storm systems, Lake Erie boaters, and anglers have been advised of imminent Small Craft Advisories and the tangible prospect of severe storms that could dramatically affect the western basin. The NWS has already issued advisories for Tuesday into Wednesday, with winds ramping up to speeds that would give pause to even the most seasoned sailor. By next week, after the warm front's chaos, a robust and deep upper-level trough is set to send temperatures tumbling, with rain and snow showers expected to close out the weekend.
