Big TIme Wind Headed Your Way!

Wind Advisory in effect until 6am Saturday, 30 hours of winds 40-45mph!


Good Morning,

A Nor'easter continues to gain strength over the waters east of Long Island and near southern New England early this

morning... As the lowest central pressure dropped from 1006 to 996 millibars during the night (or, from 29.70 to 29.41 inches

of mercury), winds out of the north and northeast on central and eastern Long Island started to pick up... And, as further

deepening occurs within the next 12-18 hours, the wind field will be rapidly expanding and the pressure gradient will be

tightening... A Wind Advisory has been posted for much of the Northeast, and it extends from the Tri-State Area northeastward

across most of southern and central New England... There are even parts of Maine which are under a High Wind Warning...

As the body of low pressure manages to stall near Cape Cod this afternoon and tonight, this won't result in a whole lot of rain for

the coastal plain (at least not anywhere south of coastal New Hampshire and Maine), but the northwest wind will be persistent,

and also very gusty... So, today and tonight, the maximum wind gusts which can occur are as follows:

- On Cape Cod, Martha's Vineyard and Nantucket/Block Islands: 55-60 mph

- On eastern Long Island, in southeastern Connecticut and for much of Rhode Island: 45-50 mph

- In the Tri-State Area, Fairfield County, CT and at the Jersey Shore: Around 45 mph

While a few widely-separated showers and strong winds impact much of the I-95 corridor south and west of Connecticut today,

the bulk of the precipitation associated with this Nor'easter will occur across upstate New York and in northern New England... In

fact, beneath a pool of colder air aloft associated with this low pressure system, a Winter Storm Watch has also been posted for

the northern Catskills (including western Ulster County), since there could be around half a foot of wet snowfall tonight in some

of the higher elevations above 2,000 feet... The wind gusts will have the potential to cause some downed trees and utility lines,

and in parts of upstate New York where most of the leaves have fallen, the combination of that and some heavy rain will lead to a

real mess -- not to mention what a heavy, wet snow will do to some trees in the Catskills and perhaps the Adirondacks...

Winds tomorrow will only weaken gradually as the pressure gradient associated with this ocean storm relaxes and the low

pressure system itself starts to drift into the Canadian Maritimes... So there'll probably still be many wind gusts that will be in the

30-40 mph range before the wind drops off dramatically early tomorrow night...

Better weather will prevail Sunday as the axis of a ridge of high pressure builds into the East, allowing for a good deal of

sunshine and a LOT LESS WIND... Most temperatures will be in the low and mid-60s Sunday afternoon... Monday is also

looking good, since the same high pressure system will be in control... But our next chance for getting some rain around here

will be increasing Monday night, and especially on Tuesday and Wednesday... During these time frames, it looks as if moisture

located in the southern Tier of states will get transported into the Ohio Valley, the mid-Atlantic states... If a nearly stationary front

with a series of low pressure waves sets up early next week, then there could be plenty of clouds, and a few rainy episodes...

No extremely warm or cold weather seems imminent during the next 5-7 days, with most temperatures averaging near to slightly

below normal... Have a good weekend!
