As temperatures begin to drop across the region, the National Weather Service in Cleveland is anticipating a significant chill and potential for accumulating snow from Sunday night into Tuesday, which could shake up the already brisk November weather patterns. The forecast discussion issued early this morning points to a strong low-pressure system that's set to usher in much colder air entering the Great Lakes, and folks near the lakeshore can expect spotty showers as another cold front makes its way through today.
The emerging low pressure system, that's currently tracking across the Mississippi Valley, will inch closer to southern jurisdictions of the National Weather Service Cleveland area by Sunday, subsequently dragging in a vehemently chill blast with rain poised to transition into snow for northwest Ohio come pre-dawn Sunday - though a transitory upswing in temperatures in the upper 30s could stave off the final switch to snow until later in the day. Rain changes to snow west to east after 18Z, and while the whole conversion should be realized by Monday evening, the finer particulars of snowfall accrual depend largely on the whims of low-level flows and uncooperative patches of dry air.
With the contentious swirl of the system exiting stage right by Tuesday, all eyes will be set upon the surface and low-level flows off the lakes, and with the warming influence of mid-50-degree water temperatures buttressing against the stealthy, frosty tendrils of 850mb air around -11C, the resultant precipitation will primarily hinge around our trusty Lake Erie. However, according to the National Weather Service, keep your snow shovels at the ready but expectations in check; snowfall estimates remain 'manageable' despite the occasional moderate flurries.
While chilly grips are expected to persist with 30-degree days and 20-degree nights early next week, we’ll witness a gradual uptick in the mercury as upper ridging muscles over the Midwest, potentially nudging temperatures into the upper 40s. The local mariners aren't left out of this atmospheric tango—with north and northeasterly winds ratcheting up to 25-30 knots Sunday and waves cresting at 6 to 9 feet, a Small Craft Advisory was in effect until early this morning, and lake goers should brace for gusty conditions that may rival gales midweek when a trough lumbers into the region.
