Winter Storm Warnings for Oklahoma, Idaho, Texas as Heavy Snow, Large Hail and Strong Winds Possible

A winter storm will move into the Central and Southern Plains from Tuesday before heading toward the Northeast region later this week. Heavy snow and severe thunderstorms with strong winds and large hail are possible in the South, including in Texas, Oklahoma and New Mexico, while a band of snow and ice will develop just north of the storm track, the National Weather Service warns.

The storm system has been building in the Rockies in the Northwest on Monday. "Heavy snow will overspread the region today [Monday] along with strong gusty winds. Tues into Wed, the focus moves to the southern plains where ice and snow could make for tricky travel midweek," the National Weather Service advised in a post on its official Twitter account.

"South of this storm, severe thunderstorms and heavy rainfall will pose a risk for flooding from the Lower Mississippi Valley to the Mid-Atlantic coast," the NWS adds.

Farther north across the southern Great Lakes and into New England, lighter snow is expected later this week, with freezing rain likely across parts of the Ohio Valley and in Pennsylvania.

While the Northeast has been experiencing spring-like weather in recent days, temperatures will drop into the teens in northern New England and the 20s in western New York and central New England by Wednesday. Temperatures will dip a bit less from central Pennsylvania to southern New England where they will be in the 30s and the upper mid-Atlantic coast will be in the 40s, AccuWeather reports.

Rainfall in the South could be between two and four inches across parts of Kentucky and Tennessee by Thursday morning, while the region from Louisiana to Alabama may be hit with severe thunderstorms. With a strong low pressure system currently over Texas, major snowfall is very likely from west-central Texas to central Oklahoma, where winter storm warnings are in effect, with some parts of the region forecast to see four to eight inches of snow by Wednesday night, the NWS notes.

A Winter Storm Warning is in effect in parts of central, southern and southwest Oklahoma and northern Texas from 9 p.m. (local time) Tuesday through 6 p.m. (Iocal time) Wednesday, while the same warning is in effect from noon (local time) Tuesday in the Rolling Plains and much of the South Plains of Texas, the NWS states.

A winter storm centered over the southern Plains Tuesday will shift to the Northeast through this week. A band of snow and ice is expected to develop along a front extending to the Northeast mid to late week. To the South, severe thunderstorms and heavy rainfall are forecast.

A Winter Storm Warning is issued when a significant combination of hazardous winter weather is occurring or imminent, while a Winter Weather Advisory is issued when either freezing rain or between two and four inches of snow are expected to cause a significant inconvenience, but not at a level that warrants a warning, the NWS explains.

The Sacramento Mountains region of Texas is under a Winter Weather Advisory from now through 5 a.m. (local time) Wednesday, with snow accumulation between two and four inches expected and up to six inches at elevations above 8,000 feet.

"Snow is expected this morning [Tuesday] through this afternoon, initially above 7,000 feet before gradually lowering to around 6,000 feet. Snow may taper off later this afternoon before a second round of snow begins this evening. Snowfall will create slick roads and reduce visibility making for hazardous travel conditions," the NWS warns.

Only general thunderstorms are expected today, but as a storm system moves into the Southeast tomorrow, several days of severe thunderstorms are possible with strong winds and large hail the main threats. Know where to go to take shelter if severe weather threatens your location!

A Winter Weather Advisory remains in effect until 8 p.m. (local time) Tuesday in parts of New Mexico including East Slopes Sangre de Cristo Mountains, Central Highlands, South Central Mountains, Johnson and the Bartlett Mesas region including the Raton Pass, the far Northeast Highlands, Northeast Highlands, Harding County, Eastern San Miguel County, Guadalupe County and Southwest Chaves County.

A Winter Weather Advisory is also in place from 11 p.m. (local time) Tuesday to 11 p.m. (local time) Wednesday in the Weiser River basin region of Idaho.

"Moisture from the Gulf of Alaska will bring snow to east-central Oregon and west-central Idaho beginning late tonight [Tuesday] through Thursday. Mountains will see moderate to heavy snowfall accumulations," the NWS warns.
