Snow, Ice for West, Midwest, Northeast From new winter system

Winter safety and preparedness

A low pressure area will move in cold air that is delivered by high pressure from Tuesday to Wednesday, resulting in widespread snow and ice from parts of the Midwest to the East.

  • A new storm system will bring snow to the southwest and central High Plains until Monday evening.
  • This system will bring large amounts of snow and ice to the Midwest and parts of the east from Tuesday to Thursday.
  • Winter storm watches are issued in the east of the Washington D.C. and Baltimore metro areas.

A storm system at the moment in the southwest will bring a widespread winter mess of snow and ice to parts of the plains, Midwest and East, during the first half of the week.

Happens now

This storm is currently dumping snow on the southern Rockies, including parts of Arizona, Colorado and New Mexico.

Up to 14.1 inches of snow has been reported at the airport in Flagstaff, Arizona, from Monday morning.

Snow even fell parts of the metro area of ​​Las Vegas late Sunday evening. The snow forced a closure of Interstate 15 Monday morning from the southern end of the Las Vegas Valley to the California border.

This storm also brought extra heavy snowfall to Sierra Nevada in California during the weekend, snarling travel.

Warnings for winter weather

(From the National Weather Service)

Winter weather warnings and winter weather warnings are issued by the National Weather Service in parts of the southwest and central High Plains.

Winter Storm watches are also posted in parts of the Midwest and Mid-Atlantic, including Des Moines, Iowa, Washington D.C. and Baltimore.



  • Snow will continue until Monday evening in the southern Rockies.
  • Parts of the Albuquerque and Santa Fe, New Mexico, metropolitan areas will see snow blowing from Monday morning to Monday evening.

Tuesday-Tuesday evening

  • From New Mexico and Colorado snow is expected during the day in the Texas Panhandle, western and central Oklahoma, Kansas, Nebraska, South Dakota, Missouri and parts of Iowa.
  • A narrow area of ​​ice-cold rain and sleet could cut roads from west-central Texas into central Oklahoma, southern Missouri and northwest Arkansas.
  • Snow will spread further to the north and the east on Tuesday evening to the upper Midwest and the Great Lakes. A mix of snow, sleet and sleet can flow from central Missouri to the Ohio Valley.
  • Snow or ice can also occur in the mid-Atlantic and southern Appalachians.

Tuesday forecast

(The green shades indicate where rain is expected.) Areas that are blue shaded are expected to snow. Purple shaded locations can see rain or snow, pink areas are expected to see sleet or ice (ice).)

Wednesday-Wednesday evening

  • Snow will spill over the upper Midwest and parts of the Great Lakes, with implications for travel in Des Moines, Iowa, Minneapolis-St. Paul and Milwaukee.
  • A combination of snow, wet snow and sleet is likely to affect travel in the Mid-Atlantic and parts of the Northeast.
  • The Washington D.C., Baltimore and Philadelphia subways will see piling up of snow before they switch to a mix of snow, sleet and rain. This would make the morning commute in those cities dangerous.
  • New York City was able to see a few inches of snow on Wednesday before it changed rain on Wednesday night. The snow can affect the afternoon commute.
  • The mess of snow and ice spreads on New England Wednesday to New York, including Boston, where a first blizzard will probably turn into rain.

Forecast of Wednesday

(The green shades indicate where rain is expected.) Areas that are blue shaded are expected to snow. Purple shaded locations can see rain or snow, pink areas are expected to see sleet or ice (ice).)


  • Snow and ice can linger in the north of New England and in the north of the state of New York.

Snow and ice forecast

  • Parts of Southern Colorado southern Rockies in northern New Mexico may receive more than 6 centimeters of snow, with localized amounts to a height of the highest altitude.
  • Most locations in the Plains and Midwest get less than 6 centimeters of snow from this system.
  • The biggest probability of snow totals of 6-plus-inches is in parts of the upper Mississippi Valley, including from Iowa to southern Minnesota.
  • In the east, the biggest chance is half a foot or more snow in the central Appalachians.
  • The subways of Washington D.C. and Baltimore could see up to 6 inches of snow. Snow totals in those cities will depend on how fast the transition to snow and sleet occurs, although that part of the forecast is uncertain. A faster transition would result in lower snow totals.
  • At least slight ice formation is possible from parts of the Ozarks in the middle of the Mississippi Valley, Ohio Valley, Appalachians and Mid-Atlantic.
  • In most areas, this ice will be an impact for travelers on untreated roads.
  • Some heavier amounts of ice can damage the central Appalachians, causing damage to the trees and dispersion of power. This includes an area of ​​Northwest North Carolina in West Virginia, East West Virginia and South Central Pennsylvania.
