Most of the upcoming weekend should be pretty good weatherwise, but probably not all of it.
An upper-level low pressure area will pull away tonight, but a few showers are still possible through the first part of the night, mainly near the coastline. High pressure builds in for Friday into Saturday with drier conditions. While Friday should feature a decent amount of sunshine, Saturday will likely have more clouds as a weak system passes by to the north. Could it produce a few showers? Maybe, but mainly in southern New Hampshire.
Sunday is when things get really tricky. A low pressure area will be slowly moving in from the west, sending a warm front toward the region. The question is, how far north does the warm front get before stalling out? This will have a large impact on temperatures. Our best estimate at this point is that it will at least get up to the Mass Pike, but beyond that, we’re not sure. South of the warm front, it will be warm and humid, with temperatures likely getting into the 70s. North of the front it may stay in the upper 50s and lower 60s. The next question is – when does the rain move in? Right now, it looks like we may have some showers late Sunday afternoon and evening ahead of the warm front, but that isn’t set in stone at this point. Late Sunday night into Monday do look wetter, but again, this is far from a lock.
