The 4 Day Forecast is visually deceiving; (Much like me right now. Trust me, I AM decent looking under the ginger stache!) lots of snow icons in a forecast that won't actually feature much snow. See, we have some snow squalls tonight (no big deal), then some light snow Saturday (still no big deal) followed by a light mixture over northern Maine on Sunday (the littlest deal of all).
Rest of today: A mixture of sun and clouds and quite chilly. Not chilly as far as raw air temperature (mainly mid 30s), but more in terms of wind chill as winds gust around 20-25 MPH in most spots. By late this afternoon a round of snow squalls will enter the mountains of western Maine and northern New Hampshire. Most of us will wait until this evening to see any flakes however.
Tonight: Those snow squalls are associated with an arctic cold front pushing down from Canada (our first true arctic of the season). My experience with these fronts has been that the mountains squeeze out a solid 1-2" of snow quickly, the foothills get a nice coating and the coastline sees very little in the way of accumulation...just some flakes. That's how I think tonight will play out, so be advised over western Maine that there could be a brief burst of moderate snow and gusty winds but if you are reading this from closer to the coastline just a few snow showers will do it. I've made an accumulation map (largely because I'm bored), it's on the graphics page.
Friday: Mostly sunny and cold. Temperatures struggle to get out of the 20s and in many spots do not. Southern Maine will see some increasing cloud cover by the afternoon...but they will be the exception to the general clear rule. Winds continue to be a bit gusty, adding to the frigid feel.
A warm front starts slinking towards us by Saturday and sets up a classic "overrunning" light snow scenario. Basically as the warmer air approaches Maine it is forced upward in the atmosphere as it "overruns" the cold air dome in place from Friday. The net result is some periods of light snow over southern Maine and up to the Midcoast on Saturday afternoon. All indications are that accumulation will be minimal to non existent...probably in the dusting to 1" range. Still it could be a bit of a nuisance for travel. This is only southern and Midcoastal Maine though, the rest of the state is mostly cloudy and quiet.
A brief mixture/some freezing rain situation could set up Sunday morning over northern Maine as the warm front continues to push north, but for most of us Sunday will be overcast and warmer.
An all rain front comes through Sunday night before we settle into a very mild Monday/Tuesday. Highs on those two days will likely crack 50 F.
Ok only one day left to donate to my Movember cause...let's finish strong! http://mobro.co/keithcarson
