Retrograding Low Pressures!

What is this, March? Sure feels likes it. We have been stuck in a nasty easterly flow for the past 2 days and we still have one more day left. If this pattern brings back memories of early spring time, you aren't far from the truth.

A combination of an upper level low over New York state and a stalled out low pressure system just south of Nantucket is the same pattern that kept eastern Mass on the warm side of late winter storms as well as the same pattern that gave us record breaking rain in March. Think of it as mother natures way of reminding you all that she is in charge and even though this "blast from the past" sticks around for a few days, keep it in mind for our Fall and early Winter seasons. Seems like we might be seeing this again.

As for tomorrow, the Low pressure system regains strength off our coast overnight as this NAM image shows. Looks like most of the heavy precip stays offshore but this is no guarantee. Don't be surprised if we have a very similar day to today.


The good news is that after tomorrow, a STRONG High Pressure system sets up shop all of next week and brings a potential heat wave to the east coast. Summer isn't over yet!
