As the citizens of Cleveland look to the skies this Tuesday morning, the forecast promises a mixed bag of weather conditions over the next few days. In the latest update from the National Weather Service in Cleveland, a very weak trough hovers over the area while a cold front from the western Great Lakes approaches it. "Forecast remains valid per latest trends in obs and model guidance," says the NWS Cleveland update, ensuring no significant changes are expected in the immediate weather pattern.
Those venturing early may encounter patchy and dense radiation fog, especially west of roughly I-71. With breaks in the clouds and abundant low-level moisture, patches of dense fog formed, though the localized nature of the fog has so far skirted the need for a Dense Fog Advisory. According to the NWS Cleveland, forecasters predict the fog will dissipate later in the morning, thanks to diurnal convective mixing of the boundary layer.
Later in the day, the region can expect fair weather until midday before the approach of the shortwave trough and cold front brings chances for scattered rain showers. With conditions heating up to the 70s before the cold front passes and a concoction of weak MUCAPE, steep low-level lapse rates, and moderate effective bulk shear, "isolated thunderstorms capable of producing convective wind gusts up to 50 mph" are also on the table for northern Ohio, reports the National Weather Service. A small craft advisory kicks into gear late this afternoon, warning of strong winds and waves over Lake Erie that could potentially escalate from 5 to 8 feet in the central basin tonight.
The short-term forecast starting Wednesday night portends clear skies with temperatures a few degrees above normal, mid-70s for highs, and low 50s for lows. An upper-level trough is expected to sweep across the Great Lakes region with "isolated rain showers in Northwest Pennsylvania Friday night," according to the latest statement by the NWS in Cleveland. Even though the outlook for the weekend favors sunny conditions with temperatures taking a slight dip, it's worth noting that the expected cold front on Friday could mean pulling out those warmer layers by Monday once again.
For the aviation sector, the changing weather may cause disruptions. Today on Lake Erie, various conditions are set to unfold: from very weak surface troughs lingering to a cold front sweeping through between 19Z Tuesday and 06Z Wednesday. Pilots should be prepared for a sudden shift in winds, which could ramp up to 20-30 knots post-frontal passage, and expect to relent by Wednesday morning. The air traffic could also face low cloud-induced VFR to IFR ceilings and misty conditions that should clear as the day advances. "Widespread low clouds resulting in ceilings primarily in the 5kft to 1kft AGL range are expected to persist," warns the NWS, adding a note of caution for those needing to navigate these low-visibility conditions.
