By Thursday morning, February 19, 2026, Boston was sitting on a weather tightrope. Logan Airport (KBOS) reported cloudy skies and about 31°F, with light north winds keeping most of the city hovering right around freezing. After Wednesday’s bands of rain and wet snow, all that lingering moisture on the roads sets the stage for trouble once temperatures slip later on. As readings drop through the evening, that wet pavement is primed to refreeze, creating a real risk of black ice for the Thursday morning commute, especially on secondary streets, bridges, and highway ramps.
Black Ice Tonight Into Thursday Morning
According to a National Weather Service special weather statement, temperatures are expected to fall into the 20s overnight, and “areas of black ice” may develop and persist into the Thursday morning commute. Light winds will actually work against drivers, limiting how quickly wet surfaces can dry out. That leaves untreated roads and elevated surfaces like overpasses and ramps as the biggest concern.
Drivers are urged to slow down, leave extra space between vehicles, and treat shaded intersections and bridges as likely slick spots. In other words, assume the pavement is worse than it looks.
How To Prepare
If you can, delay nonessential travel on Thursday morning and give yourself extra time if you have to be on the road. Clear all snow and ice from your vehicle’s windows, leave a wider gap behind other cars, and avoid sudden braking or sharp turns on bridges and ramps where black ice likes to hide.
Transit riders should check MBTA updates before heading out. Road crews will be treating major routes, but neighborhood streets and less-traveled areas may stay slick into the morning.
Friday Commute And Weekend Outlook
The relatively simple black-ice threat quickly evolves into a more complicated story on Friday, February 20, 2026. Forecasters say a larger system will move in with a wintry mix that may start as snow in the morning, flip to rain near the coast during the day, and then transition back to snow Friday night. The National Weather Service forecast discussion highlights ongoing uncertainty in both precipitation type and amounts.
As it stands, the metro area may pick up anything from a dusting to a couple of inches of snow inland, with sleet or freezing rain possible over higher terrain and during those changeover periods. Either way, travel on Friday afternoon and evening looks messy.
On Saturday, February 21, 2026, conditions should trend colder with a chance of lingering light snow. Forecast guidance also hints at a stronger coastal system late Sunday into Monday that could bring heavier snow and coastal impacts if current trends hold.
Bottom Line
Tonight into Thursday morning, treat every road as if it could be icy and plan for slower commutes through the day. Keep an eye on updates from the National Weather Service and check with your transit operator before heading out if you rely on buses, trains, or ferries.
