Weather Synopsis November 6, 2012

(Cold air in place ahead of a coastal storm)
Chilly temperatures are greeting many across the Northeast this election day thanks to a cool high pressure system sitting over the region. Expect high temperatures generally in the 40s for most of the region, with 30s into northern New England. Despite the cold temperatures, this system of high pressure is also producing fair weather for today for the entire region with partly cloudy to mostly sunny skies. For tonight, mostly clear skies will prevail as that  high pressure system stays in place, this will allow temperatures to dip into the 20s across much of the region, with 30s along the coast from Boston down to Philly. As we head into Wednesday, fair weather will continue over the Great Lakes, however we'll be monitoring our next weather maker making its way into the picture that will be affecting coastal communities along the Midatlantic and southern New England. A strengthening storm will ride up the eastern seaboard from coastal North Carolina to the Midatlantic on Wednesday. This system is expected to rapidly intensify off the Midatlantic coast from Wednesday evening into early Thursday morning producing heavy precipitation and strong gusty winds for some of the same coastal areas already ravished by Hurricane Sandy one week ago. Winds could gust up and over 50 miles per hour along the immediate coast on Wednesday night from the Jersey Shore to Long Island to Cape Cod. Precipitation will start off as rain Wednesday afternoon initially.

( Rain to start, mixing with snow and sleet overnight Wednesday)
Then depending on the track of this storm as it comes up the coast, there could be enough cold air dragged in on the back side of the storm to produce a  mix of rain wet snow and sleet Wednesday night and early Thursday morning with a light accumulation from New Jersey to western Long Island including New York City, up to western Connecticut, western Massachusetts, southern Vermont and New Hampshire, to Maine. A slight change in the storm track would change this forecast considerably. If the storm track closer to the coast precipitation would remain in the form of rain for these areas, with any frozen precipitation pushing further inland. Temperature wise, we can expect the chilly temperatures to stick around for the next few days before a brief warm up heads our way this weekend, with some temperature readings in the 60s returning to the picture on Sunday.
