According to the National Weather Service, residents in the Cleveland area should ready themselves for a shift in weather as the calm spell courtesy of lingering high pressure gives way to an approaching cold front. As the high-pressure system takes its leave to the Atlantic Coast, the cold front is expected to land late tonight and pass through the southern Great Lakes on Wednesday, resulting in possible scattered showers and a noteworthy temperature dip.
The NWS update from this morning confirms no substantial changes to the forecast. Still, the twofold interplay of a dissipating upper-level trough and the cold front offers a point of interest—the former is only likely to increase cloud cover. At the same time, the latter prompts a switch-up with fresh, breezy conditions and a cooler airmass in tow, although with modest rainfall anticipated in the eastern zones of the CWA, we're looking at a few hundredths at most. The most significant telltale sign will be the shift of winds to the northwest after the front's passage.
The National Weather Service forecast also details that the melee of weather elements continues with a transient high pressure expected to usher in more agreeable conditions by Thursday. However, they'll be short-lived as another cold front is hot on its heels by Friday evening, possibly spurring isolated thunderstorms amidst rain showers. Temperatures are on a roller coaster ride, too. Thursday's highs will hover in the mid to upper 50s, whereas Friday sees a slight hike to the mid to upper 60s before returning to cooler climes come nightfall.
In the long-term outlook, the departure of the cold front on Saturday could spur some lake effect showers—especially within the snowbelt regions—but predominantly high pressure should promise a mostly dry tenure for the rest of the weekend and early next week with a gentle rebound of temperatures into the low to mid-60s as the region crawls back from overnight lows that settle into the 30s.
For mariners, anticipate increased wind activities with south-southwest breezes setting in today and amplifying tonight up to 25 knots as they shift to a northwesterly direction come Wednesday—conditions which will likely call for a Small Craft Advisory on Lake Erie, despite not being officially hoisted yet, the advisories are predicted to be necessitated given the looming 24-hour lead time. The marine conditions should begin to mitigate Wednesday night as high pressure starts to dominate from the west.
While climate records are unlikely to topple in Cleveland this year, Tuesday teases with highs edging close to previous record temperatures documented over the years at various locations across Ohio, per the latest climate data referenced by the National Weather Service.
