Pacific Northwest Snowfall Friday through Sunday Well ahead of next week, mountain snows develop across the Washington Cascades Friday with a few inches of snow at Pass levels.  Saturday into Sunday a more vigorous system will bring a round of heavier precipitation to the region with an area from the Cascades through Bitterroots getting over a foot of snow.  Some of the passes could begin with snowfall but as the weekend progresses the snow levels are expected to rise to 6,000 to 7,000 ft. Higher elevations will likely see 1 to 2 feet of snow.(MORE: Pacific Northwest Deluge This Weekend)Christmas Storm Possible For The Great Lakes Through Northeast Models are relatively consistent with advertising a deep low developing across the Great Lakes Region Wednesday, Christmas Eve. This system is tagged for consideration to name.  If it were to be named that would probably occur in the Monday to Tuesday time frame. The timing for winter impacts are listed below by day:Christmas Eve The system will circulate warm air ahead of it along the East Coast Christmas Eve bringing a soggy mess to the Eastern Seaboard.  From Washington to New York to Boston it will be a cold rain. Farther back to the west across the Great Lakes and Upper Midwest cold air will filter in to produce a snow event.  It is too early to determine the exact snow amounts. However, it is also forecast to be windy and the combination of wind and snow will create a travel mess for the Upper Midwest through Upper Great Lakes.  The rainfall on the East Coast may create significant travel impacts, especially to air travel Christmas Eve.Christmas Day ForecastnlargeChristmas Day Forecast Christmas Day The cold front associated with the system will cross the Lower Great Lakes through New England on Christmas Day and change rain to snow.  However by the time the cold air filters in, much of the precipitation will already have fallen so snowfall amounts may not be that significant except for the higher elevations of Interior New England through Upstate New York to western Pennsylvania.  Nevertheless, brisk winds could combine with the snowfall to produce travel impacts as well. (POLL: What Cities Will See a White Christmas?Christmas Storm For the West A system is forecast to race from the Pacific across the Inter-Mountain West and emerge east of the Rockies and spread snow across the Plains in the Wednesday through Thursday night time frame.  Model solutions still show a lot of uncertainty with this system.  At this point consensus suggests snow developing across the Northern Sierra through Southern Cascades Christmas Eve then spreads rapidly east across the Inter-Mountain West to the Central Rockies Christmas Day.  Although it is way too early to get into details, there are suggestions that the track of the Low could be favorable for significant „upslope” snowfall to develop along the Front Range of the Rockies including the Denver area. This system is also tagged for consideration to name and the naming could take place in the Monday to Tuesday time frame.(MORE: Christmas Week Outlook)Forecast: How Much Snow?48-Hour Snowfall Forecast48-Hour Snowfall ForecastNow: Snow, Sleet, Freezing RainCurrent Winter RadarCurrent Winter Radar Where’s the Cold?Current TemperaturesCurrent Temperatures2014-2015’s Winter Storm Names

In an effort to increase awareness and enhance communication of disruptive, impactful winter storms, The Weather Channel named winter storms starting in the 2012-2013 season. We are using a new list of names, shown above, for the 2014-2015 season.(MORE: Origin of the Names | Science Behind Naming Winter Storms)In 2012-2013, there were 27 named winter storms spanning over five months beginning with the post-Sandy Winter Storm Athena in early November and ending with Winter Storm Achilles in early May.(RECAP: Winter 2012-2013 Named Storms)In 2013-2014, there were 26 named winter storms beginning in early October with historic High Plains Winter Storm Atlas and ending with a mid-May Rockies snowstorm, Winter Storm Zephyr.(RECAP: Winter 2013-2014 Named Storms)Not every winter weather system will receive a name. The Weather Channel has specific criteria in place to determine when we name a particular winter storm. Our two main criteria for naming a winter storm are:
  • It is forecast to produce conditions that meet the National Weather Service winter-weather warning threshold(s) over a main population center or multiple states, beginning generally within 48 hours.
  • It is forecast to produce winter weather conditions that would be historic, especially unusual, or memorable, beginning generally within 48 hours.
