Our long run of above normal temperatures is finally coming to an end.
A cold front moved through the area overnight and delivered some cooler, more seasonable Autumn air to the Northeast and New England.
Temperatures will top out in the lower 50s today, tomorrow and likely on Thursday as well…which is a few degrees below the long-term average for the date (average high at Hyannis for November 8th is 55F). Nighttime lows will be in the 30s and lower 40s (about on target for this time of year), though if winds can slacken off tomorrow night, readings in the lower 30s – with pockets of frost – would be possible.
The story doesn’t end there, however.
A shot of very cold air for November-standards is poised to drop into the region late this week and sit over New England for much of the weekend. Temperatures will hold in the 40s on Friday and then fall sharply Friday night as northwest winds howl. By Saturday morning, most, if not all of the Cape, should be below freezing with many spots down into the 20s. In fact, model guidance is emphatic on temperatures in the lower 20s across most of the Mid and Upper Cape! Readings will struggle to get back to 40F on Saturday and will likely hold in the 40s again on Sunday.
