Tuesday, April 21 opened on the chilly side in Boston, with mostly clear skies and temperatures in the mid-30s (about 34°F at Boston Logan, KBOS). The sun looks like it will hang around through the afternoon, but clouds are set to roll in tonight as a wet system gears up for a Wednesday arrival.
This Afternoon
Expect mostly sunny skies with a high near 47°F and northeast winds around 6–12 mph, which will keep things feeling crisp and a bit breezy. Coastal neighborhoods should run a little cooler, while inland spots could sneak a few degrees warmer by late day.
Rain Wednesday, April 22
Rain is likely Wednesday morning, with showers developing after about 7 a.m. and a daytime high only near 46°F. According to the National Weather Service, totals should stay light at generally under a tenth of an inch. Higher terrain could briefly mix with some wet snow very early, and south winds of 8–12 mph will help lock in a damp, gray commute.
Thursday Into The Weekend
A slow-moving low over the Canadian Maritimes is expected to keep conditions cooler and a bit unsettled on Thursday, with the best chance for additional light showers then. From Friday into the weekend, conditions trend drier with highs generally in the low-to-mid 50s, though coastal areas will likely run a bit cooler than inland locations.
Commute And What To Bring
Green Line B branch riders should be ready for changes. Service between Kenmore and Boston College will be suspended from April 22 through April 30, and shuttle buses may creep along more slowly on wet streets, according to Boston.gov. A waterproof jacket and umbrella will serve you well, and it is a good idea to budget extra time for shuttle replacement service during Wednesday’s rainy stretches.
