Boston woke up socked in by dense fog and on-and-off drizzle on Saturday morning, March 7, with Logan sitting at about 36°F and visibility knocked down across the city. Pockets of freezing drizzle hung on over the higher terrain overnight, creating a risk of black ice on untreated surfaces for the morning commute. Drivers and pedestrians should keep an eye out for slick bridges, shady stretches and parking lots as the sun comes up.
Areas of drizzle and patchy fog are expected to hang around before 4 p.m., with skies staying mostly cloudy and a high near 49°F. South winds of 5 to 14 mph will keep things damp and sluggish at times, so plan on slower-than-usual travel today, according to NWS Boston.
Foggy Mornings, Warmer Afternoons
A Special Weather Statement highlighted pockets of freezing drizzle and the threat of black ice in the higher terrain, a concern that should ease once temperatures climb above freezing later this morning. Hoodline's March 6 coverage flagged the messy commute and urged extra caution on bridges and in higher spots, advice that still fits for Saturday's drive.
Tonight Into Sunday
Patchy fog is expected to redevelop tonight, and a weakening band of showers may brush the region from late this evening into early Sunday, with a slight chance of a rumble of thunder. Lows near 45°F should creep higher overnight, and Sunday should top out near 61°F inland. The immediate south coast may stay cooler thanks to colder ocean temperatures, according to NWS Boston.
Weekend Warm-Up And Flood Watch
A spring-like warm-up is on deck for next week, with highs possibly reaching the 60s and even the 70s in some spots. That fast melt of the remaining snowpack brings a modest risk for minor river flooding between Monday and Tuesday. Local coverage has been flagging the flood potential for low-lying, river-adjacent neighborhoods, so residents should stay tuned to updates from local authorities and the National Weather Service, via Boston 25.
What To Do This Morning
Give yourself extra time for the morning commute, slow down in low visibility, and watch untreated surfaces for black ice, especially on bridges, overpasses and parking lots. Mariners should note that Small Craft Advisories remain likely across the outer waters through the weekend, so check marine notices before heading out and bring a waterproof layer.
