There is a caveat here, and it could contribute to greater precipitation, or, frankly, it might not; looking at this glorious wind map, take a look at the incredibly dense and high strung low pressure system south of Greenland- it has sustained winds of 145 km/h, and by virtue of its cog-like motion, it is accidentally speeding up the southern and adjacent high pressure system (spinning clockwise), causing upper air winds near 40 km/h to barrel straight into the New England coast. Additionally, two nearby systems contribute to the retrograde airflow. This is a temporary arrangement of course, but it will slow the procession of the storm significantly. If anything, at least, this culmination of multiple local systems (and the Greenland one alongside) is the reason it will linger at all in the first place. The little low pressure system bearing fronts off the southeast coast might occlude with the incoming one, or, if the upper one narrowly passes unoccluded, could follow in its place (b2b). Either way, essentially, Im saying this will last a while, and these data indicate succinctly why. Looking at the big picture can help you in your travels and also determine how conditions have spread to wherever you think youve gone to outrun it, so it always behooves you to look a bit further; always cultivate your curiosity- you might find you have interest in something youve never heard of before. Systems function like cogs- forecasting is about layering data and assessing how these systems are impacted in all vectors and dimensions and aspects.
