Holiday Storms

From the Weather Channel:
“Post-Christmas Travel Weather Forecast: Delays Likely for Many This Weekend"

At a Glance
- A significant winter storm is shaping up this weekend in the Midwest.
- Heavy snow and strong winds may produce blizzard conditions at times in the Northern Plains.
- Some snow and ice will also spread to parts of New England and upstate New York.
- Heavy snow has already pummeled the mountains of the Southwest. 
A powerful winter storm will bring heavy snow, some ice and possible blizzard conditions to parts of the Plains this weekend, before spreading snow and ice into the Great Lakes and parts of the Northeast into early week, potentially snarling holiday travel. This significant system has been named Winter Storm Gage by The Weather Channel.

Happening Now: Snow and ice have spread into the Northern and Central Plains and parts of the upper Mississippi Valley and the northern Great Lakes. Farther south, rain and thunderstorms are moving through the Central and Southern Plains, as well as into the mid-Mississippi Valley. A few severe thunderstorms are possible across portions of the mid-South.  A number of winter storm warnings and winter weather advisories have been issued by the National Weather Service from parts of the Central Plains region into the upper Midwest.  A winter storm watch has been issued for parts of New England and eastern New York from Sunday evening through Tuesday afternoon where ice may become a concern. In general, the worst conditions are expected where winter storm warnings are in effect. Strong wind gusts, blowing and drifting snow and icy conditions may make travel impossible, especially in the Northern Plains.  Mixed precipitation could make roads slick from southeastern Colorado to northern Michigan, including the Twin Cities, where winter weather advisories are in effect. 

Midwest Forecast:
Timing -Sunday into Monday: Snow will linger while winds may actually increase in the Northern Plains, with precipitation eventually changing to snow across much of the upper Mississippi Valley. Areas of lingering light snow and gusty winds may last in parts of the upper Mississippi Valley and Great Lakes Monday and Tuesday. A few severe thunderstorms could develop Sunday afternoon and evening from eastern Louisiana into the western Florida Panhandle northward into southern Kentucky. Strong wind gusts and an isolated tornado are the primary threat
Sunday's Forecast: Rain, Snow Forecast: The best chance of seeing heavy snow will be from central South Dakota into northern Minnesota, with over a foot of snow possible in this general area.  Strong winds could lead to blizzard conditions this weekend, perhaps lasting into at least early Monday in the Plains. You need to make alternate plans if you have travel plans this weekend in this area. Road closures, including stretches of interstate highways, are  Some ice accumulation is possible from eastern South Dakota into the Upper Peninsula of Michigan that may lead to hazardous roads, particularly overpasses, and may trigger some power outages. Ice accumulations of 0.10 inches or less can cause travel to be extremely dangerous but usually are not damaging to trees and power lines.

Northeast Forecast:
Timing : By Sunday, precipitation should spread into most of the East. Warmer air on southerly winds should keep precipitation mainly in the form of rain for most in the Northeast Sunday and Sunday night, with the exception of northern New York and parts of New England, where stubborn cold air will allow areas of freezing rain, sleet and snow to coat surfaces. Monday, colder air and the potential of an area of low pressure forming off the New England seaboard should allow precipitation to change to snow in parts of upstate New York as well as in central and northern New England. Monday's Forecast: Some snow will linger in the interior Northeast into New Year's Eve (Tuesday), with rain showers in southern New England.
Rain, Snow Forecast: The majority of computer forecast models suggest the Interstate 95 corridor from southern New England to Washington, D.C. should see predominantly rain, rather than ice or snow, but impacts for central and northern New England could be significant. Parts of northern New England and northeastern New York may pick up moderate to locally heavy snow accumulations, while moderate to locally heavy rainfall is possible toward the coast. In between the warmer rain to the south and the colder snow to the north, some kind of mix of sleet, freezing rain and snow is likely for large portions of central New England and eastern New York.  Specifically, the higher terrain of eastern New York, western and central Massachusetts and southern Vermont, there is moderate to high potential for a significant icing.  Portions of the Berkshires, Litchfield Hills and Adirondacks seem to have to possibility of up to 1/2" of icing if the temperature profiles in the lower levels of the atmosphere line up correctly for ice. If warmer air becomes present, this precipitation may fall as rain. Colder air would produce snow or sleet.  This kind of icing could lead to dangerous travel conditions, scattered power outages and tree damage. 

^ I am in the path of this storm and am supposed to get ice and a lot of snow on tonight and through Monday and then more snow on New Year’s Eve. ^
