MARATHON FORECAST
It’s a cold start to Marathon Monday with folks waking up to frost on the ground! Enjoy the morning sunlight because clouds will build in the afternoon. Highs will climb to the mid to upper 40s by the end of the race, but a gusty west wind will make it feel colder, so dress in layers if cheering on the runners! Luckily FOR runners, this will be a tail wind.
We’ll also have to dodge a couple pop-up showers, especially in the afternoon as an upper-level disturbance pushes through... grab something to keep you dry just in case! With very cold air aloft, we can’t rule out some graupel or even inland snow mixed with some of these showers, along with brief gusty winds.
REST OF THE WEEK
Tuesday starts off cold with morning lows dropping into the 20s in the ‘burbs, around freezing in Boston. Highs reach the upper 40s with some sunshine and a few clouds. A weak disturbance brings the chance for showers late Tuesday night into early Wednesday; overall temps rise to seasonal levels by the mid to late week with highs in the 50s & 60s.
