Weekly Outlook

Weekly Outlook: December 24-30, 2018

To qualify as a White Christmas meteorologically, we need to have 1″ or more of snow on the ground at 7am Christmas morning. We’re likely not going to have that this year, but that doesn’t mean the ground will be bare in some areas.

The week starts off with a weak system passing south of the region this morning and an upper-level disturbance crossing the region later today and tonight. Between these two, we’ll have some light snow and snow showers across the area today and tonight. Most of us will just see a dusting of snow, but it wouldn;t be a surprise if a few places picked up 1/2″ to 1″. Nothing major, but just enough to make the ground white in time for Christmas. As for Christmas itself, high pressure will build back in with sunshine and cooler conditions. The high will remain in place through Thursday with the dry and seasonably cool conditions expected.

By Friday, another system will be heading towards the Great Lakes. We’ll have milder air out ahead of it, with rain likely. We could see a little freezing rain at the start, especiallyinto central New Hampshire, as the colder air may be a little slow to depart. Friday looks wet and mild at this point. The storm passes to our north Friday night, dragging a cold front through early on Saturday, with drier and cooler weather returning during the day on Saturday after a mild start. Another Alberta Clipper will come through on Sunday with some light snow expected.

If you’re looking ahead to New Year’s Eve – right now it’s looking windy and cold with some snow showers as the Alberta Clipper pulls away from the region. If you’re planning to be outside for First Night activities, the models right now are showing temperatures in the teens with wind chills near or below zero. Obviously, we’ll have a closer look at the forecast in next week’s outlook.
