If THIS is an accurate pictorial for a normal cold front, then THIS is a good visualization of today's front. Point is, it's weaker. A lot weaker.
The boundary is currently pushing through western Maine but it is a shell of its former self (my wife will say that about me once I lose my hair), producing nothing more than increased cloud cover and a few sprinkles.
Today: Sprinkles push from west to east with the front, moving out of southern Maine by 10 AM, out of the Midcoast by noon, and lingering over Downeast through 3 PM. Again though, this activity is light and scattered so it won't ruin your plans. Behind the boundary look for a distinct transition to mostly sunny skies and dry air. Northwest winds will pick up a bit by the afternoon, pushing more Canadian air into the state and drying out the stubborn to clear spots over northern and Downeast Maine. Temperatures top out in the upper 60s to low 70s.
Tonight: Cool and quiet under mostly clear skies. Temperatures will drop into the 40s along the coastline but 30s further inland. There is a Frost Advisory in effect for Oxford and Franklin counties, areas likely to see at least patchy frost.
Sunday: With high pressure in place we are looking at a pleasant day. Mostly sunny skies will be the rule BUT it will be cool. High temperatures will stay in the 60s and a strong wind from the northwest will remind you that Fall is creeping (trust me on this one) in.
Sunday Night: Even cooler than Saturday night. Lows will drop to freezing in the mountains with low 40s even along the immediate coastline.
Monday: High pressure still rules the Northeast so look for another sunny day. Temperatures should recover a bit into the upper 60s to low 70s as winds shift.
Rain is still scheduled for late Tuesday through Wednesday morning but the latest data suggests the axis of heaviest precipitation will be to our west over VT and NY. Still I think we are good for 1" of rain statewide with some higher amounts in the mountains. I'm interested to see what the computer models spit out tomorrow morning as they may trend back to heavy rain for Maine if the feature is being improperly resolved on the large scale. (Nerd talk for I'll make a final call tomorrow)
I'm out for now. Enjoy your day!
