There’s a weak weather system headed for southern Maine Monday morning and it is likely going to bring some snow to much of the area, including greater Portland.

Snow will move across Maine Monday morning and early in the afternoon.

Few forecasting situation don’t have their challenges.  Monday’s snow brings several possible issues, none of them major, but each can change the outcome of what you observe.

I think most areas will see some snow.  The further north you travel, the less likely there will be snow, just a few flurries.

Snow is likely in parts of Monday morning.

When Will The Snow Fall?

The timing of this event looks to be during and just after the morning commute. Roughly 4 a.m to 2p.m. is when the snow will fall over the region, but it will start later further east, and end earlier west.  After this period, temperatures will warm enough at the coast for some mixing or it will just simply be over anyway..

Snow will be breaking out west of Maine in the early morning hours Monday.

How Much Snow Will You See?

As far as accumulations, I am expecting a coating to an inch or two of snow.  Some spots in southwest New Hampshire could receive just over 2 inches if everything worked out just right and there was a heavier burst for an hour.

Will The Snow Stick?

Temperatures are going to fall quickly tonight with clear skies.  As an aside, be sure to check out Venus and the Moon in the southwestern sky again.

With temperatures below freezing and roads also become colder the snow will stick.  Of course treated roads won’t be an issue, but untreated surfaces could be slick for a few hours Monday.

What Could Change?

Since this is light event there isn’t much wiggle room for changes.  On the upper end of the scale the 1 inch line could make it closer to  Portland and a bit north or alternatively the just seeing a few flakes to a coating line could be further south.

When is our next system?

There’s another system possible with some light precipitation in the middle of the week.  I do see much colder air arriving this weekend. As I mentioned several weeks ago, this December is going to be much colder and likely snowier than last year.
