A weak area of low pressure, tied to an Arctic cold front, was over central New England this morning, and will continue to track northeast away from the Capital Region today. A cold airmass was in place this morning, and is forecast to continue through the start of the weekend. Another reinforcing shot of colder air, in the form of another fast moving cold front, looks to pass through the area early Friday morning. Cold high pressure to our north briefly builds into the region through the day Friday, and this will likely send temperatures on Friday night into the single digits (above zero). Lower readings will be possible further north and west, where snowfall has accumulated a bit more.
The weekend looks a bit turbulent, in terms of the weather, as a storm system moves from the Mississippi Valley Saturday morning, to the Mid Atlantic coast by Sunday morning. The combination of an inland low pressure area over the upper Great Lakes, and cold high pressure to our north over southeastern Canada, will help ensure that any moisture that falls from the skies through this period over the Capital Region will be in the form of snow.
Activity will wind down by Sunday afternoon, becoming just snow showers. High pressure builds into the region to start the new work week, with another weaker system approaching by Tuesday of next week, bringing the chance for additional precipitation, and a slight moderation in temperature.
