The National Weather Service in Cleveland is closely monitoring a low-pressure system poised to introduce a dynamic weather pattern to the region starting late today. The forecast discussion details the arrival of a warm front, trailed by a potent cold front expected to induce a band of scattered rain showers across the forecast area as it moves through Sunday evening into Monday.
Temperatures ahead of this cold front are set to soar into the 60s, thanks in part to warm air advection. Dew points will also be on the rise, reaching into the 50s, which "should be strong enough to trigger some showers and storms across the region," despite some atmospheric capping, the NWS Cleveland advisory stated. The primary threat from these incoming storms appears to be the potential for damaging winds and large hail, with a rope of 70 knots of 0-6 km bulk shear coinciding with a 70 kt 500 mb jet streak escorting the frontal boundary, according to the same source.
By Monday night, as the cold front exits southeastward, a wedge of drier weather is expected, but only temporarily. Shortly after, another more convincing cold front is forecasted to once again bring volatile weather conditions Tuesday, including potential rain showers mainly east of the I-71 corridor along with the possibility of snow in some areas. Tuesday, temperatures will also struggle to climb, ranging from the mid-40s to around 50, with west-northwest winds gusting 30-40 MPH due to ongoing cold air advection.
Marine activity will be affected as well, with the NWS anticipating a Small Craft Advisory from late Monday through midweek. On Lake Erie, "light/southerly winds of 10kt or less" are expected today but will pick up in intensity with the arrival of the warm front, potentially reaching gale force on Tuesday over the central basin, which "will build 1 to 3-foot waves in the open waters tonight into Monday," the advisory suggested.
High pressure is set to bring some relief by mid-week, reducing winds and ushering in drier conditions. By Thursday, the high-pressure system will create a more tranquil environment across the Great Lakes. However, another low-pressure front coming in from the west is predicted to onset increased shower activity and potential thunderstorms toward the week's end. Nonetheless, with the forecast still a few days out, there remains some uncertainty regarding the exact evolution of this weather system.
