The National Weather Service in Cleveland has issued a Winter Storm Watch for a significant portion of Ohio and parts of Pennsylvania, in anticipation of a potentially major snowfall event slated to impact the region from Saturday evening through Monday. According to the NWS forecast discussion, the storm is likely to produce moderate to heavy accumulations. Areas east of the I-71 corridor are expected to bear the brunt of the snowfall, with at least 6 inches projected and possibilities of totals reaching 12 inches or more, although those higher accumulations remain less certain.
In addition to the snowfall, the forecast has underscored concerns about a prolonged cold snap, with sub-zero wind chills anticipated to start on Friday and potentially extend into the following week. It's been advised to prepare for dangerously cold conditions, with wind chills potentially reaching as low as -15 degrees F. "A Cold Weather Advisory may be needed as early as Friday morning," the NWS has indicated, suggesting imminent action to protect against the impending freeze.
Further to the wintry conditions, a cold front moving east is expected to cause a brief period of snow showers and gusty winds, primarily affecting the northern half of the forecast area. Wind gusts of 40 to 45 mph have been observed following the front's passage. The NWS has also noted that current conditions are likely to limit additional snow accumulations and coverage of snow showers.
Meanwhile, aviation forecasts for the area are calling for VFR (Visual Flight Rules) conditions in most sites early on, with a shift to MVFR (Marginal Visual Flight Rules) due to additional snow and lower visibility later in the night. Lake Erie's marine conditions will be influenced by breezy west to southwest winds through Friday and a potential for 20-30 knot winds. Northeast winds are to strengthen come Sunday, as a low-pressure system crosses the Ohio Valley.
The cold temperatures and accumulating snow will also contribute to the expansion of ice across Lake Erie, which is already largely ice-covered. The continued cold is expected to facilitate further ice growth over the next week. Those navigating Lake Erie's waters or residing in the affected areas should stay tuned to the National Weather Service for the latest updates and advisories.
