Effective: Mon December 1, 2025, 6:58 AM

Patchy black ice is possible this morning, as temperatures have fallen below freezing. Moisture remaining from yesterday's rain is refreezing, creating slick conditions on untreated surfaces like sidewalks, driveways, and bridges. Conditions will improve later this morning as temperatures rise above freezing. Motorist and pedestrians should use caution. Reduce speed, allow extra time, and be prepared for areas of slippery travel.

Visibilities may drop below 1/4 mile due to falling and blowing snow. Periods of moderate and heavy snow will combine with low visibility to create dangerous driving conditions. The hazardous conditions could impact the Tuesday morning and evening commutes.
Monitor the latest forecasts for updates on this situation. Persons should consider delaying all travel. If travel is absolutely necessary, drive with extreme caution. Consider taking a winter storm kit along with you, including such items as tire chains, booster cables, flashlight, shovel, blankets and extra clothing.
