Winter storm names: The entire list of names this season and the science behind how we name them.

Spring Freeze

  • A highly amplified jet stream pattern is in full force across the country with a large West Coast ridge and a deep trough in the East.
  • This pattern leads to extreme temperatures in both regions with unseasonably cold weather East and record warmth West.
  • The cold air has settled into the South and East with temperatures plummeting 15-25 degrees below average for the first half of the weekend.
  • Freezing temperatures anticipated for parts of the South where trees and early flowers are blooming Saturday and Sunday mornings.
  • Spotty record lows are possible Saturday and Sunday morning with a hard freeze (mid 20s) possible for parts of the deep South.
  • Temps remain generally at or below average Great Lakes and Northeast into next week as most other areas see a nice warmup.

Spring Snow

  • A clipper system tracks from the Upper Midwest into the Great Lakes and Northeast Sunday and Monday.
  • Light snow is likely with this system northern Minnesota to northern Michigan and into northern New England.
  • One thing to keep in mind, a Norlun trough may try to bring some light snow coastal New England to New Jersey Saturday.
  • Still uncertainty on exact location and intensity, but a few inches of snow could fall

Northern Storm Track

  • A series of disturbances will ride along the jet stream across the northern U.S. from late weekend through next week
  • The first system will produce Sunday showers from the upper Mississippi Valley to the upper Great Lakes down to the Ohio valley (snow mix north)
  • Another system brings rain/thunder to the Midwest and Great Lakes Wednesday
  • Some rain/snow showers over parts of New England Wednesday

2014-2015'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.

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.
