It’s a slippery morning in much of Maine with temperatures below freezing and a winter weather advisory posted. This advisory will be lifted by mid-morning inland and earlier along the coast. In the mountains the advisory is posted into the afternoon.

Highs this afternoon will reach the 40s along the coastal plain and into the 30s well north and west. Some mountain areas may never really get above freezing until very late in the day.

There is a risk for a few light showers during the day today, but the bulk of the overnight mess is behind us. I would take the rain coat or umbrella if you need to walk any significant distance just to play it safe. Once mid-afternoon arrives the risk of any rain falls closer to zero and this will make for a drier and less slippery commute home than the one into work.

Thursday and Friday bring high pressure, the dry weather system, into the region. Since the high is coming from Canada the air is going to be cold, but it’s not coming from the arctic so it won’t be bitter. Highs will reach the upper 20s to lower 30s with the colder of the two days being Friday.

A small system brings some snow showers to the area on Saturday with lingering clouds for Sunday. It will be seasonably chilly, meaning the colder side of average, but not out of the ordinary by any means.

Late in the weekend the models are forecasting another coastal storm. It’s been an active fall and this pattern of a storm track up the coastline looks like it’s going to continue for a while. It’s way too early to say whether this system brings us rain, snow or is a miss.

You might ask, why talk about it if you don’t know more specifics yet? What’s great about the longer range forecasts is that they are likely correct there will be a storm. Here it is Wednesday morning and already the major computer models we use agree something is going to develop in the Atlantic and threaten New England. I think that is worth noting. What the models don’t know is the track and intensity. In these situations just 200 miles can make a huge difference between shoveling, umbrellas or needing sunglasses.

The follow maps are courtesy WeatherBell Analystics the first shows the Euro’s position of the predicted coastal storm Monday December 8th, the second is the GFS’s map for the same time.

If you hate having any chance of being stuck in an airport you could plan not to travel on those days where there is even a small chance of a snow event. This would mean staying away from Monday the 8th as of now. During the winter I will continue to let you know very early when weather might impact travel, it’s important you realize these are probabilities at this point and all I can say is the chance of a storm Monday is above zero. Think of this like weather insurance, you might not need it, but when you do, you’ll be glad you read this.
