NATIONAL WEATHER ONLINE - NORTHEAST REGION

Wrapping up the Blizzard of '10

I'm sure you've heard about the Blizzard of 2010 by now.  It is long gone, but the damage has certainly been done.  Hundreds of thousands lost power due to the weight of the wet, heavy snow.  Some areas received over 3 feet!  Colesville, MD took the prize of the most snow with 40".  Unfortunately for storm-weary Mid-Atlantic residents, another storm may impact the region during the middle part of the week, bringing more accumulating snow!  This one may track a bit farther north, impacting New York City and Southern New England as well.  As always, the exact track determines how much snow falls.  It'll be a fun one to track.

Hybrid storm continues backing toward the Mid-Atlantic - damaging wind threat thru Fri AM

(** 9:25 PM Update:  Delaware Bay buoy 44009, 16 foot seas, 36 mph sustained NNE wind, gusts to 47 mph.  Thanks for the info via Twitter @weatheronline!!)

At issue this evening is the creature that's been retrograding westward toward the Mid-Atlantic coast.  I'd hoped to post here about this storm earlier today, but was limited on time and ended up tweeting instead.  First, to set my frame of reference, I'll include the list of my tweets from 11 AM this morning (I'm @mattnoyes on Twitter for those who'd like to follow).  Then, I'll deliver my thoughts on where we stand as of now (Thursday night):

List of Tweets From 11 AM:

• Initiating a full analysis of the storm developing off NJ coast. Need to determine what, if any, potential exists of this going tropical.
• Visible and IR satellite imagery indicates dual convective clusters rotating around mid-level center, *displaced* from low level center
• Though mid-level circulation is displaced, t'storm clusters are both N/NE and S/SW of surface low at long/lat 72W, 36N
• Atlantic City, NJ, marina gusting 38 mph. Largely pressure gradient driven. 36 mph gusts buoys 44025, 44017, 44008, all far from storm.
• Water temp under storm circulation is abt 80 degrees. MIT potential storm strength puts this area as Cat 3 or 4, 960-965 mb potential.
• Mid-level wind shear is strong, 4cast to weaken, then pick back up again. 35-40 mph gusts will continue, but stronger wind core to develop.
• Summary: Storm at 36N/72W to move W and "landfall" Southern Delaware Bay approx 2AM. Tropical features, but not tropical.
• Wind too removed S side of storm, shear too great to allow full organization, symmetry is lost by day's end.
• Mixing to 950mb with wind 55-60 kt means gust 60+ mph Cntrl/Srn NJ coast likely, iso 70 mph possible but unlikely to b recorded.
• In NewEng, gust to 40mph Long Island Sound early Fri AM, coastal flooding W end of sound. Otherwise, breezy leftover rain all that's left!

8:30 PM EDT THURSDAY ANALYSIS - HYBRID CREATURE RAMPING UP:

So, now the question is, how is this coming together this evening and where do we stand on the potential for damaging wind associated with the circulation.  I have to say I was quite surprised...

Rare November Tornado Watch Issued For Portions of The Northeast

Rain showers don't keep the deer away

A mild but active southeast wind brought whitecaps to Rehobeth and Dewey Beaches, but the wind surfers and surfers were enjoying. Here, deer are seen feeding on Assateague Island, MD, where 120 wild horses run free, as well. At 430 pm, a brief moderate shower blew through at 66 degrees. Heavy rain missed the Mid-Atlantic region for the most part today, however.

MID-ATLANTIC CONTINUES TO BE HIT HARD BY SEVERE THUNDERSTORMS

With funnel clouds reported and winds of over 100 mph, severe thunderstorms not only uprooted trees, but pushed homes clear off of their foundations Thursday night and Friday in Virginia, Maryland and North Carolina.

Severe thunderstorms caused damage around the Washington, D.C., area this weekend, uprooting trees and resulting in structural damage.  Hardest hit were Maryland suburbs of the Metro area as an energetic upper level disturbance interacted with a stationary surface front.  The video below gives a summary of the damage from the Associated Press.  Continue reading this post for the latest from the National Weather Service Office in Sterling, Virginia, on the exact details of this storm.
