The good news: The weekend forecast has improved. The bad news: That only makes it decent, not great. The Fox News: Fair & Balanced & Brutally Republican.

Today: High pressure will give us a one day reprieve from our generally wet pattern. Morning clouds and fog will be stubborn to burn off (low level moisture behind yesterday's front is trapped along the coastline), but skies will become partly sunny by the afternoon. Temperatures will respond well to this sunshine as the air mass in place is relatively mild aloft, look for highs in the 68-74 range, which is a good 5-10 F above average. Late in the afternoon I have to include an isolated sprinkle over the far northwest (right up against Canada) as a cold front approaches, but the threat is minimal.

Tonight: An isolated sprinkle is possible as that cold front pushes into western Maine. The chance of showers falls in the 10-15% range, however, so most of the state will remain dry this evening. Partly cloudy conditions will transition to mostly cloudy by the early morning. Low temperatures will be relatively mild due to the cloud cover, with lows staying in the 50s.

Saturday: At this point the cold front will be draped across the mountains so showers will begin by mid morning over western Maine. Meanwhile east of a line from Lewiston to Millinocket the shower activity won't arrive until the afternoon. Before the showers arrive there could be a few breaks of sunshine over southern coastal Maine and southern New Hampshire. But, for the most part, cloudy conditions will prevail with that boundary so very close. In short: Western Maine will be showery from start to finish but you might be able to squeeze some outdoor plans in over eastern Maine before the rain arrives. High temperatures will top out in the mid to upper 60s.

Saturday Night: Showers will continue along the coast until around 9 PM. After that the front will move offshore and gradual clearing will take place. After midnight the entire state should be partly cloudy and cooler with lows in the 40s. (I have a rare weekend morning off on Sunday so I'll be able to go out Saturday night. My pre-going-out song? This is How We Do It. If listening to that didn't make your day 25% better...you might not have a soul)

Sunday: With the cold front offshore most of Sunday will be dry. HOWEVER, Sunday will also be mostly cloudy as the boundary doesn't move far enough away to totally clear out the associated cloud deck. The best chance for some sun will be western and northern Maine, they might be far enough away from the front to sneak out partly sunny skies. Cooler air will begin rushing in from Canada so highs will be hard pressed to crack 60 F. Some light shower activity will  push into very southern Maine (Read: York and Cumberland Counties) by 4-5 PM but it shouldn't be much of a factor until the evening.

Computer models disagree on the intensity of a coastal low pressure system on Sunday night/Monday morning. If you buy the stronger solution there will be some moderate rain along the coast Sunday night with some mountain snowflakes mixed in. I am splitting the difference for now calling it light coastal rain with a flurry possible in the higher terrain. Some VERY chilly air will be pulled down from Sunday night through Monday leaving highs only in the 50s and lows in the 30s.

Columbus Day itself should be decent with a morning sprinkle over northern Maine giving way to mostly sunny skies. I say only "decent' because it will be cool and breezy. With highs in the 50s and a strong northwest wind it will be definite jacket weather for most.

We look pretty troughed out and cool for the rest of the work week with our next storm system arriving on Thursday. That system has an even better chance of bringing the first mountain flakes as it comes down from Canada.

See ya!

So I reach for my 40 and I turn it up...designated driver turn the keys to my truckkkkk....
