As the Midwest braces itself for a shift in weather patterns, Clevelanders are looking at a weekend of ventilation curated by no other hand than that of Canadian high pressure. The National Weather Service in Cleveland warns of an approaching cold front today, which will bring with it a cooler airmass as we march toward the weekend. A developing wave along the front near the Ohio Valley is also expected to stir up the atmosphere, poking at the possibility of convection, particularly near Lake Erie.
The nearly friendly banter between the waves of low pressure and the cold front, though less likely to escalate into severe threats, could still punctuate the dusk hours with isolated convective stirrings, especially in the western zones after 9 p.m., or 21Z in meteorological speak. "A severe threat is on the lower side at this time," the NWS forecaster's discussion indicates, however, winds at about 30 knots on the low level and mimicking in the mid levels could lend a hand to the storm organization into early Thursday. As we say goodbye to the upper 80s on the thermometer today, sentiments unspoken will settle as we welcome the lower to upper 70s Thursday.
Staring down the barrel of the short-term forecast, which runs from Thursday night through to Saturday night, one can almost hear the collective sigh of relief as dew points descend from previous sauna-like conditions. Prospects for temperatures in the 70s, clear skies, and markedly cooler evenings paint a pleasant picture, with some areas possibly even flirting with the upper 40s, though mainly sticking to a more modest lower 50s away from the lake's embrace and lower to mid 60s along its shores.
Looking ahead, "completely dry forecast in the short term," confirms the Area Forecast Discussion, with the weekend expected to unfurl under sunny spells and a return to the 80s by Monday – yet, the Great Lakes might dip back into the folds of upper level troughing just as the southwestern U.S. puffs up under an upper level ridge. Meanwhile, the marine forecast paints a less serene lake state, with winds sweeping across Lake Erie today, shifting northerly then picking up speed this evening with predictions of 15-25 knots running through late Friday; certain zones could push brief gusts of up to 30 knots, especially between the Islands and Willowick. Small Craft Advisories and Beach Hazard Statements stretch their arms across the marine zones.
For those with nautical inclinations, patience will be a virtue as tranquility holds off until later Saturday. But until then, "Small Craft Advisories... run into Friday or Friday night, lingering longest across the central basin," the dispatch from local meteorological minds advises. Subsequently, a more agreeable state for waterborne entertainment is on the horizon, projected to sail smoothly into the early half of the following week.
