How's this for irony: My nerdy love for the weather (thunderstorms rolling through) kept me up too late last night (9 PM...lame, I know), causing me to get less sleep than normal.... making it harder for me to do the weather this morning. THAT'S full circle, people.

Those thunderstorms last night were the leading edge of a cold front that is currently stalled along the Maine coastline. We picked up on the likelihood of this happening yesterday morning and, sure enough, it has played out as planned. With the front still nearby look for lots of clouds and scattered showers along the coastline. Meanwhile, the further west you head the more sunshine you will see as drier air pours in from the northwest (classic "the front has passed" wind direction around here). I've created a Chance of Showers map that can be found under "Weather Extra." I think the wettest region today will end up being Downeast as the curvature of the coast has them much closer to the front than the rest of the state. The most favorable region will be western Maine and into New Hampshire. Temperatures stay in the 70s in most spots with a FEW isolated low 80s.

Any remaining showers taper off by 11 PM tonight, ending last over Downeast. After that look for rapid clearing as the front finally moves totally offshore. Lows will drop into the 50s with decreasing humidity.

Sunday looks like a winner statewide with a ridge of high pressure moving in. The high won't move TOTALLY overhead but it will still be the dominant weather player as that stubborn frontal boundary will be too far offshore to give us any problems. The result? A good deal of sunshine with temperatures in the upper 70s to lower 80s.

We should be able to squeeze out another nice day on Monday, although there may be a few more clouds around in general.

Showers and thunderstorms are likely overnight Monday and into Tuesday as a weak low pressure system develops offshore. It should stay far enough away to just brush Maine with precipitation, but if it comes any closer we could be looking at heavier rain during the Tuesday time period.

A ridge of high pressure will build in on Wednesday and we are looking GOOD, real good, from Wednesday through Saturday. Upper 70s to low 80s with a bunch of sunshine.
