Good morning, everyone! High pressure is gradually making its way into New England today. Skies will become partly sunny as the day goes on with the exception of some high-level clouds. Temperatures will be a bit milder compared to the cold temperatures we’ve been seeing the past week. Summit temperatures will be in the upper 20s, with base temperatures in the lower 30s. The recent dry, cold conditions mean that many resorts have increased their snowmaking efforts. Expect mostly machine-groomed, packed powder snow conditions for the weekend. Here is a photo from Bretton Woods from yesterday:

The warm up continues into Sunday, with even summit temperatures approaching the above freezing mark. This temperature trend is driven by an approaching low pressure system that will move towards New England from the Mid-Atlantic coast . Winds will become gusty (30-40 mph gusts) on Sunday afternoon ahead of the storm. The bulk of the precipitation from this system will fall on late Sunday into Monday morning. More details on this storm are included in the extended forecast below...

Low pressure will continue to slide northeastward off the southern New England coastline through the morning hours on Monday. Light snowfall will affect eastern New York, Vermont, New Hampshire, and portions of northwestern Maine during the early morning hours on Monday, with a possibility of mixed precipitation along the way. This round of precipitation will contribute to snow accumulations around an inch or less. Here is the latest run of the GFS:

As the storm departs on Monday night, high pressure will begin to approach from the west and tighten the pressure gradient between the two systems. Strong northwesterly winds will enhance upslope snow showers through the overnight hours and bring a blast of cold air to the Northeast.

Upslope snow showers will persist through the morning hours on Tuesday for most of the region, and will continue through the afternoon for northern New Hampshire. Additional accumulations will amount to 1-2 inches and potentially up to 3-4 inches in portions of northern Vermont and New Hampshire. Summit temperatures will linger in the lower teens to upper single digits. Wind chill values will be well into the negatives, so be sure to bundle up!

High pressure will nose its way into the Northeast during the day on Wednesday, bringing calming winds and high clouds. Summit temperatures will remain in the upper teens during the day on Wednesday. High pressure remains the story until another low pressure system takes its aim on the Northeast by Friday. Both the ECMWF and GFS are suggesting a significant rain event with the latest model runs.

A lot can change between now and the end of next week. Be sure to check back for more updates!
