Cold air returned to the area overnight and will remain in place over the region through most of the upcoming week. Temperatures will be at or below seasonal averages between now and Thursday as chilly air feeds into the region. We will, however, be mostly storm-free throughout the period as dry westerly winds prevail. That said, we do have one minor weather system to monitor and that feature may give us a touch of Christmas Eve snow.
A weak area of low pressure will pass through the Northeast and New England during the day on Monday, spreading a shield of clouds and light precipitation across the region. Initially, the focus of this precipitation will be over interior parts of the Northeast, where a nice light, festive snow will fall later tonight into the early part of Monday.
As the initial system starts to exit the region a follow-up energy center high in the sky will try to catch up with it and this subtle interaction should help initiate a second round of light precipitation over eastern and southeastern portions of Southern New England later Monday afternoon and into Monday evening. Temperatures are likely to be just cold enough for that precipitation to fall in the form of some flurries or pockets of light snow…perhaps adding a nice festive look and feel to Christmas Eve…fingers crossed!
You can see the evolution of this system nicely here:
