As Bay Area residents bask in the glow of an early summer, those in Cleveland find themselves under the influence of a persistent high-pressure system. According to the National Weather Service Cleveland, the Great Lakes region enjoys largely sunny skies today with temperatures gradually inching their way upwards, despite remaining below normal. This sunny disposition is set to shift northeastward by late Tuesday as a low-pressure system bubbles up from the Mid Mississippi Valley.
While the start of the week might feel more pleasant with the sun breaking through, change is on the horizon. The NWS forecast discussion notes that "broad mid/upper troughing" continues, but the strong surface high pressure will remain mostly sunny. Tomorrow could bring a few showers, with the likelihood increasing by nighttime, especially south of the Findlay to Youngstown line. It's not until tonight that mid-level warm air advection and isentropic ascent increase, leading to a rise in high-level cirrus clouds across the region.
Moving into the short-term forecast, northeastern Ohio anticipates the arrival of a surface low pushing through the area on Wednesday. Yet, the rainfall seems to present itself in fits and starts rather than as a persistent deluge. While thunder may rumble, the chances remain dicey due to marginal surface-based instability. The evolving upper-level dynamics are expected to afford Clevelanders a brief respite from the wet spell, sometime between Wednesday night and Thursday night.
As the week chugs along, it's the weekend when things get spotty. The NWS Cleveland suggests an upper trough pushing through eastern Canada and the Northeast U.S. will spell scattered rain showers through the weekend. In a turn of events, temperatures this time are predicted to hover closer to the norm, without the recent unseasonal chill Clevelanders experienced. Set against this backdrop, the days offer a checkered outlook of intermittent rain chances and temperatures between the 60s and 70s. The weekend weather's final shape will hinge on the trajectory of the hovering upper trough, as is hinted in the long-term forecast.
Back on the waters, Lake Erie sailors and swimmers may need to exercise caution. There could be an elevated swimming risk and potential for a Small Craft Advisory due to anticipated northeast winds of about 15 to 20 knots on Tuesday. The lake is set to experience some offshore flow as the system exits, paving the way for southwest winds on Thursday. Even with the aquatic fluctuations, it appears that the weekend should settle into a pattern of west to northwest winds, in keeping with a marine forecast that sees a touch of unsettled weather playing at the fringes.
