A Slushy Shift: Wintry Mix and Evening Advisories Return to Boston

Morning: A Gloomy and Damp Start

Bostonians waking up this Thursday, March 5, 2026, will be greeted by thick cloud cover and a generally damp atmosphere. The morning hours are expected to remain gloomy with high humidity levels hovering around 83%. While significant precipitation is not anticipated during the early commute, scattered rain or sleet showers are possible, making for a raw and chilly start to the day. Temperatures will hover near the freezing mark early on, so a warm coat and waterproof footwear are highly recommended for those heading to the office or school.

Afternoon: The Calm Before the Wintry Mix

As we move into the afternoon, the city will remain under overcast skies with a predicted high temperature reaching approximately 42°F. Despite the slightly higher numbers on the thermometer, a steady breeze of about 11 mph will keep the 'feels-like' temperature significantly lower, likely in the upper 20s to low 30s. This period serves as the transition point before a more active weather system moves into the region. While the impact remains low during the daylight hours, the atmosphere will continue to saturate, setting the stage for a messy evening transition.

Evening and Overnight: Winter Weather Advisory in Effect

The weather story takes a sharper turn after sunset. The U.S. National Weather Service has issued a Winter Weather Advisory for the Boston Metro area, officially taking effect at 5:00 PM this evening and lasting through Friday morning. As temperatures begin to tick down toward a low of 30°F, daytime rain and sleet will transition into a steadier mix of wet snow and slush.

• Precipitation: Forecasters expect rain to change to a sloppy mix of sleet and snow after dark.
• Accumulation: The Boston area could see between 1 to 3 inches of wet, heavy accumulation by early Friday morning.
• Travel Impact: Untreated roadways and sidewalks are expected to become slick and treacherous as the temperature drops.

Commuter Safety and Outlook

With the advisory beginning right at the peak of the evening rush hour, commuters should prepare for slower travel times and reduced visibility. Looking ahead, this wintry system is expected to linger into Friday morning before a significant weekend warmup brings temperatures back into the 50s. For tonight, however, the focus remains on the incoming ice and snow. Residents are encouraged to clear storm drains and exercise caution on the roads as the slush begins to build up across the city.
