The first significant snowfall of the season is on the way for the NYC metro area and much of the Mid-Atlantic region. Low pressure will develop over the eastern Gulf of Mexico later today and intensify as it tracks northeastward along the east coast on Wednesday. The low is expected to pass just east of New Jersey on Wednesday evening before reaching the New England coastal waters late Wednesday night. This coastal storm will have a big impact on the interior Mid-Atlantic region on Wednesday and Wednesday night resulting in rather typical fashion in this region of generating more snow to the north and west and less snow to the south and east.
Precipitation should overspread the region from the southwest around dawn. Precipitation should start off as rain or a mixture of rain and snow before changing to all snow from northwest-to-southeast during the afternoon hours. Snow is likely for most, or all, of the storm in places well to the northwest of here such as in the Hudson Valley region. The last area to change over to snow will be over Long Island and they can expect less snowfall (2-4 inches in western and central sections). Northerly winds are forecast to increase to 10 to 20 mph on Wednesday with gusts to 25 or 30 mph possible. The snow will be of the heavy, wet variety.
As far as road conditions are concerned, initially the snow will have trouble sticking thanks to the recent round of warm weather. The worst driving conditions are likely to occur during the late afternoon and especially tomorrow evening when the effectiveness of the sun diminishes and temperatures drop to near freezing. One other note, looking ahead, signs point to a break in the weather pattern as we begin December with above-normal temperatures quite likely for awhile.
