Bostonians waking up to a mixed bag of weather today should expect a slight tease of afternoon showers before a clearer skies take the stage on Marathon Monday. The National Weather Service predicts a 30 percent chance of rain post 5pm with partly sunny conditions and a high near 60 degrees. Come nightfall, the chance of showers jumps to 50 percent before concluding around 11pm.
Looking ahead, Marathon Monday is expected to be mostly sunny with highs brushing 65 degrees — optimal for the spectators, but potentially sweat-inducing for the long-distance runners hitting the pavement, depending on personal thermostat settings. "Enjoy a sun and clouds Sunday morning before rain chances increase by the evening," NBC Boston reports, tipping off citizens on the temperate days ahead.
The outlook for Tuesday shows a continuation of sunshine with a high near 64, featuring gentle west northwest winds blowing between 7 and 10 mph. These conditions are likely to hold through the evening, making for another clear night with the thermometer dipping to around 42.
However, the fair weather isn't set to last with the midweek forecast signaling a shift. Wednesday starts off partly sunny but soon gives way to rain chances by nightfall. "Midweek changes bring in rain chances by late Wednesday," NBC Boston states, forecasting a damp tail end to what starts as a runner's and spectator's dream weather scenario for the historic Boston Marathon.
Thursday's runners and commuters should brace for a dreary day with rain likely and highs only cresting the low 50s. The pattern of potential precipitation continues through Friday and Saturday, posing a threat for weekend activities with unsettled weather and temps hovering in the high 50s. As always, these conditions are no strangers to New England's fickle springs, and Boston's resilient residents will likely take the week's mixed signals in stride, umbrellas at the ready.
