It pains me to tell you this, because I know Mainers LOVE humidity, but significantly drier air is on the way today. Bye bye humidity, hello normal air. (Using the quasi-throwback phrase "Peace out" in the title made me go through all the other discarded-but-once-popular-sign off phrases in my head: Lates (hated this one, it saves you ZERO letters), toodles, I'm outie, throwing deuces up, TTYL. Am I missing any?)
A cold frontal boundary is slowing moving through the state this morning. You may have thought the front moved through last night because of the showers and storms, but that activity was actually WELL out ahead of the air mass boundary. Once the front moves offshore by late morning (early afternoon Downeast), winds will turn west and the dry air will spill in from Canada.
Today: A few clouds as the front passes through this morning, otherwise mostly sunny. Dew points drop from 70 or so to the upper 50s by the afternoon, and that will make all the difference in the world. High temperatures will end up in the low 80s in most spots, some 70s along the immediate coastline.
Tonight: You can finally turn off that AC. Mostly clear skies and the lower humidity allow temperatures to drop into the mid 50s in most spots.
Tuesday and Wednesday: Safe to lump these days in together as a ridge of high pressure dominates bringing mostly sunny skies. Dew points will be in the low 60s so it's not fall-like crisp air, but it's reasonable enough. High temperatures in the low 80s along the coastline, mid 80s inland.
A cold front will pull through by Thursday afternoon, introducing our next chance of precipitation. It should just be garden variety pop up thunderstorms by the afternoon, however, and most of the day will remain dry and pleasant.
I wish I could say the same about Friday and Saturday. The computer models have locked into a large low pressure system spinning up the coastline and bringing us rain from Friday afternoon through Saturday. Still a while out so the timing may change, but for now I would pencil in losing half the weekend to soggy conditions.
