Near record warmth Thursday with highs in the mid-upper 80's! Let's do it all again shall we? More sunshine on Friday with highs mostly in the mid 80's with light SW winds. I do expect an afternoon seabreeze to cool the coast during the afternoon. The upper level ridge will hold on for the first half of the weekend with more sunshine and unseasonal warmth, though temperatures will be a few degrees cooler, mostly in the Lwr 80's Saturday, with sea breezes keeping temps in the 70's at the coast.
I guess the lone weather maker of the next few days is a weak cold front pushing through Saturday night. Low pressure from the Great Lakes will track into Canada and slide a cold front through Saturday evening with a few clouds and maybe an isolated shower. The cold front will be off shore Sunday morning with clearing skies from west to east with increasing sunshine. Breezy NW winds will help direct a cooler more fall-like airmass into the New England with highs in the 60's and Lwr 70's. High pressure from the midwest will shift east and sit right over us Monday and Tuesday and wrap in a cooler wind direction from the NE. This will provide more sunshine but the cool onshore wind component will help to keep temps in the 60's and lwr 70's
This High will go a long way to keeping tropical moisture suppressed south of New England through the midweek with slightly moderating temps into the mid-70's. Another high will slide out of Canada and provide a reinforcing shot of cooler than normal, dry Canadian air just in time for next weekend. This is it folks. The last official weekend of summer. The unseasonal warmth is about to end. Will upper 80's return again? Not in this month. And then in October...it becomes even harder to do with the sun lower in the sky and shorter days. So moral of the story...live this weekend like you are dying...because...well...we are not getting any younger! Have a great weekend!
