Mid-Atlantic – The Week Ahead (Oct 31-Nov 7)

Winds will begin to subside tonight as we start to get cooler again. Temperatures this week will generally be below average, which is likely a trend that will prevail over the next couple of months, with occasional warm shots between extended periods of cooler weather. The first snow flakes for D.C. could be seen this week as a coastal storm forms around mid-week. The models are still having a tough time on precipitation timing and placement, but it looks like the region should get a healthy dose of rain late Wednesday night through Thursday. On the back end of this system, cooler air and lingering moisture could bring some light snow into the region, with some accumulation expected on the western side of the Appalachians through the second half of the week.

This mid-week system will be very hard to predict as two pockets of energy, one lifting from the Southeast and one diving in from the Northern Plains, collide over the Mid-Atlantic region. How these two pockets of energy evolve and interact will be crucial in bringing precipitation to different parts of the region.

As this system lifts to the north and east, northerly winds will keep the region on the cooler side over the weekend. Another low pressure system could form off of the East Coast late next weekend, which could bring some wintry precipitation to the coastal areas as we head into next week.

The summer-like conditions are finally over. It’s time to prepare for winter.
