Massive Sou'easter could bring damaging winds to Eastern MA


USCAPEWEATHERAF

Recommended Posts

After reviewing the 00z and 6z HIRES model data, there is the potential for the Cape and Islands to receive hurricane force winds tomorrow afternoon into the evening.  A powerful sub 985mb surface low will pass to the west of the region, allowing a warm front to penetrate northward into at least central new England and then allow most of SNE to warm sector.  A line of potentially strong to severe storms will impact the region within the next 48 hours.  These storms could produce damaging to hurricane force wind gusts as the precipitation drag occurs.

Inverted. Yawn.

Probably...waters are getting toward climo mins even if TAN pulls a 57/57. Over 80kt at 950 though.

If we can get near 60 interior SE MA as usual has the best shot. It's tough on CC with those waters.

It’s pretty slick out there. Weenies up here, please use caution.

Ditto that.   25.2F  light freezing rain too.  After a couple of below zero days the ground is super cold.  My driveway is absolutely unwalkable right now.  Waiting on the warm air,  so close  (look upwards) yet so far.

50F here in Harwich, MA, winds today could top 70mph especially if we get any convection in a line to develop later this afternoon into the evening hours.  Weakest GFS shows 85 knots at 925mb, while most other guidance shows 95mph winds sustained at 925mb and 100 knots at 850mb.  GFS shows -30C temps at 800mb next week.
