Discussion
After a very mild weekend, noticeably colder air has moved into the Mid-Atlantic region during the overnight hours and a reinforcing cold air mass will push into the area for the second half of the week. One impulse of energy should generate some snow activity on Tuesday with small accumulations possible and then, as the next cold air mass approaches the region, a wave of low pressure is likely to form near the Mid-Atlantic coastline early Wednesday. Some snow is likely to break out late Tuesday night/early Wednesday as this low pressure system organizes near the coast and additional small accumulations are possible. Once this mid-week low pressure system departs, another cold air mass that had its origins in Siberia will move into the Mid-Atlantic region.
Looking elsewhere, a change in the overall pattern over the Pacific Ocean will bring two separate systems into California later this week (Wed/Thurs) and during the early part of the weekend (Fri/Sat). The result should be substantial rainfall to coastal California over the next 5 or 6 days along with several feet of snow to the interior mountain locations (Sierra Nevada). The second system is likely to be the stronger one at the end of the week, but both systems could ultimately affect the weather in the eastern U.S. Specifically, the first (weaker) system could produce some light snow in the eastern states early this weekend and then the second (stronger) system has a chance to cause big problems in the eastern states in about a week's time. Stay tuned on that one.
