Today’s Commute: Gusts and a Few Showers
Commuters can expect a blustery ride as any lingering light rain moves out and clouds gradually thin during the afternoon. According to the National Weather Service, the chance of measurable rain is around 30 percent this morning, with winds easing after sunset. If you have lightweight outdoor furniture or decorations, it is a good idea to secure them before those early-day gusts kick in.
