随着风暴向东行进，冬季风暴警报在拉斯维加斯北部生效，并延伸到墨西哥边境。
亚利桑那州的图森正在接受冬季天气咨询。图森市的居民可能会遭遇与纽约市周二相同的降雪量。
这场风暴将进入中心地带，在周四和周五带来一场恶劣天气的爆发。
首先，从德克萨斯州到田纳西州，恶劣天气的风险已经增加，在那里，整晚都有可能出现非常大的冰雹、破坏性的大风和强烈的龙卷风。
接下来是周四的主要威胁，届时可能会出现强龙卷风，风速可达每小时70英里。周四的靶心城市包括达拉斯、小石城、德克萨肯纳和什里夫波特。
大雨可能会导致从俄克拉荷马州到田纳西州的洪水泛滥。
这种恶劣的天气在周五向东南部移动，阿拉巴马州、乔治亚州和卡罗莱纳州处于风暴区。
到周五下午，同样的风暴系统将从芝加哥到纽约带来降雪或寒冷天气，并给华盛顿特区和费城带来大雨。
Cross-country storm slams the West before bringing tornadoes to the South
A major cross-country storm that first brought blizzard conditions to California is now heading to Nevada and Arizona before taking aim on the South.
In the wake of the storm,Yosemite National Parkis buried under 15 feet of snow and is closed indefinitely.
Near Lake Tahoe, California, an avalanche buried the first two stories of a three-story apartment building Tuesday night. No injuries were reported, according to the Placer County sheriff.
In San Bernardino County, California, where some residents are stranded, officials said Wednesday, "Our No. 1 priority is to get our residents the food, the medicine and access that they need. Plowing is going to continue over the course of the next several days."
As the storm marches east, winter storm warnings are in effect north of Las Vegas and extend to the Mexican border.
Tucson, Arizona, is under a winter weather advisory. Tucson residents could get the same amount of snow that New York City saw on Tuesday.
This storm then will move into the Heartland, bringing a severe weather outbreak on Thursday and Friday.
First, an enhanced risk for severe weather has been issued from Texas to Tennessee, where very large hail, damaging winds and strong tornadoes are possible through the evening.
Then comes the major threat on Thursday when strong tornadoes are possible and winds could top 70 mph. Cities in the bulls'-eye on Thursday include Dallas, Little Rock, Texarkana and Shreveport.
Heavy rain could lead to flash flooding from Oklahoma to Tennessee.
This severe weather moves into the southeast on Friday, with Alabama, Georgia and the Carolinas in the storm zone.
By Friday afternoon, that same storm system will bring snow or a wintry mix from Chicago to New York City, and heavy rain to Washington, D.C., and Philadelphia.
