An unseasonably warm start to our weekend with high temperatures flirting with 50° by the early afternoon under peeks of sunshine. However, today is the “calm before the storm” as the severe weather close to the Gulf will continue to materialize and strengthen as it paves its way up the east coast, into the mid-Atlantic by Sunday evening and into southern New England by Monday morning.
Before this potent system moves in, Sunday will start off mostly cloudy similar to this morning with temperatures into the mid-30s, but the clouds stick around through the afternoon and evening with showers starting along the southern coastline along CT, RI, and along the southern Cape and Islands, as early as noon. Highs will only reach into the low to mid-40s. Through the afternoon and early evening, these showers will extend farther northward from the southern coastline, into downtown Boston by dinner time (6:30 p.m.) with showers likely around Gillette Stadium by that time. Tailgating remains dry, but the rain will approach by kickoff of the Steelers vs. Patriots game. Showers should start to lighten up by the end of the game, but temperatures will still remain in the mid to upper 30s, so no threat of snow mixing in, at least for tomorrow night.
As those showers depart late Sunday night, that’s when the potent system makes its final approach to southern New England. A High Wind Watch has already been issued for the Cape and the Islands, including Block Island, Rhode Island in anticipation for the strong, possibly damaging wind gusts that are expected to be the strongest Monday night. We’re talking 50-60 miles per hour gusts along the southern New England coastline. Expect power outages and downed trees. If the storm lines up with the timing of high tides, coastal flooding is still a possibility.
Along with the high winds, heavy rainfall is expected through Tuesday with this system as early estimates place southeastern Massachusetts under 1-3” of rainfall. However, some areas of ice, freezing rain, and snow will extend into central and western Massachusetts, making for slow and dangerous travel for the Monday evening commute and into Tuesday morning’s commute.
