Boston woke up to winter’s version of a banana peel on Thursday, with mostly clear skies at Logan, temperatures hovering around 32°F and patchy freezing fog quietly turning untreated surfaces slick. The National Weather Service rolled out a Special Weather Statement early this morning, warning that leftover snowmelt combined with sub-freezing air has created icy spots on roads and sidewalks. Slippery conditions are expected through about 9 a.m., so commuters are urged to build in extra time and stay alert for thin ice on ramps and bridges.

Morning Travel Alert

“A combination of snow melt, below freezing temperatures, and freezing fog have led to very slippery travel conditions this morning,” the National Weather Service Boston/Norton said in an early-morning statement. Untreated sidewalks and ramps may be especially slick through about 9 a.m., and both drivers and pedestrians are advised to slow down and use caution. For the official notice, see NWS Boston/Norton.

What This Means For Travel

Logan is still digging out from this week’s nor’easter, and Massport has warned travelers to expect delays and to check flight status before heading to the airport. Local transit and ride-share trips may run slower than usual as crews treat streets, so plan on padding your commute this morning, especially on elevated ramps and bridges that ice up first.

Afternoon And Week Ahead

The rest of Thursday should brighten up, with skies turning sunnier, a high near 37°F and a light west wind around 5 to 8 mph, which should help most neighborhoods thaw out this afternoon. Saturday looks milder, with highs around 44°F, although a passing cold front could bring a chance of light snow Sunday morning with less than half an inch expected in the city. An Arctic airmass is then on track to arrive early next week, likely pushing lows into the single digits and keeping Monday’s highs only in the low 20s, so it is not time to stash the winter gear just yet.
