The National Weather Service in Cleveland has indicated that a high-pressure system will continue to park itself over the region through Monday, meaning residents can expect the mercury to rise along with humidity levels stepping up a notch today. According to the latest report, temperatures may very well flirt with the 90s, especially along and west of the I-75 corridor, and it's only getting hotter on Sunday, so make sure your air conditioning units are in fighting shape.
While high pressure typically spells out clear skies, there's a chance you'll see some pop-up lake breeze-induced showers and thundershowers, although at this point it's not a sure bet, but this could change in a New York minute, so for the love of all that is cozy, maybe don't leave your laundry out to dry or plan a picnic without a backup plan. Dew points are on the upswing, too—expect them to reach the mid to upper 60s starting today with hints that they might tap into the lower 70s if you're hanging out on the lakeshore in northwestern and north-central Ohio.
Moving into the week, don't put away those fans yet. The heatwave will keep on rolling through Tuesday with anticipated highs maintaining their grip in the upper 80s and lower 90s, though those looking up might catch a few more clouds and perhaps some rain by Tuesday afternoon as a cold front starts nosing in from the northwest—and with dew points hanging in the steamy upper 60s to lower 70s, it could get muggy enough to make your hair stand on end or at least curl a little more than usual.
As for the impending cold front waffling somewhere over the Great Lakes mid-week, that brings a big fat question mark on the forecast charts. The weather wonks seem to be scratching their heads a bit over the precise trajectory of that front which means, yes, you guessed it—more unpredictability with shower and storm chances lingering like unwanted houseguests right through to Friday, with the primary concern being potential heavy rains that could keep umbrellas up and gardeners grinning as long as it doesn't decide to overstay its welcome.
Lake Erie sailors and those looking to enjoy the water will be glad to know that it's smooth sailing with high pressure from New England extending a friendly hand over the water through the weekend. It's all about light breezes and soft waves, although come Tuesday, thunderstorms could play the part of party crasher, and these winds might shift from the southwest between 5-15 knots as that fickle front finally figures out where it wants to flop.
Bottom line: weather in the region seems to be as steady as a game of musical chairs for now, but if you're a betting person, bet on heat, a chance of flash umbrella openings, and maybe keep the number of your local pool handy.
