The National Weather Service (NWS) in Cleveland has forecasted a stretch of primarily sunny and stable weather conditions for the eastern Great Lakes to the New England region, under the influence of high pressure through Thursday. A slight shift in the weather is expected with a weak cold front pushing across the area on Friday, followed by reinforcing high pressure for the weekend. This information was detailed in their NWS Area Forecast Discussion, which was issued early Monday morning.
Monday's early hours saw localized fog in parts of Northwest and North Central OH. The NWS Cleveland issued a targeted Special Weather Statement to address the patchy dense fog, affecting visibility during the morning commute. In their report, they noted "<1/4 mile visibility" in certain areas identified via webcams, AWOS observations, and nighttime microphysics GOES imagery. The trend of limited fog is expected to continue early Tuesday morning, with overnight lows once again in the 50s.
As we head into the short term, Tuesday through Wednesday night, the weather is anticipated to remain uneventful. The high pressure over New England will slightly weaken, but a narrow axis of weak high pressure will persist across the Great Lakes, thus sustaining quiet weather. Skies should remain mainly clear, with only occasional afternoon cumulus and very patchy radiation fog. Daytime highs are forecast to hover in the upper 70s along the immediate lakeshore to the low-mid 80s elsewhere.
Looking further ahead into the weekend, the NWS predicts the continuation of dry and warm conditions for Thursday. The weekend forecast suggests a breakdown of the current ridging as an upper trough and weak surface low approach the Ohio Valley/Great Lakes, potentially bringing rain by Sunday. "Dry, quiet and warm weather continues for Thursday as has been the forecast for days," states the NWS Cleveland report. Although the presence of a backdoor cold front on Friday or Friday night could bring about subtle changes in the weather, no significant rainfall is expected until possibly Sunday or Monday.
In terms of aviation and marine impacts, VFR conditions are expected to persist, with chances of MVFR visibility on the lake in the early mornings. Northeast winds are predicted to elevate on the Central basin of Lake Erie this afternoon through early evening, leading to moderate swim risks and 2 to 4 feet waves.
