Widespread snow and some ice will develop from parts of the Plains and Midwest to the mid-Atlantic by this weekend as a new storm system moves across those regions.

High pressure has moved over the Midwest and East, providing a fresh supply of cold air.

An area of low pressure will tap into that cold air as it moves from the South to off the East Coast Friday through Sunday. There will be accumulating snow and some ice along and to the north of where the low tracks.

A weather system will move across the southern and eastern United States late this week into the weekend, when it will encounter a fresh supply of cold air. Accumulating snow is likely along the path of this storm.

This appears to be a moderate snow and ice event for most areas from the central Plains to the mid-Mississippi Valley, Ohio Valley, central and southern Appalachians and mid-Atlantic. Travel impacts are likely this weekend in parts of those regions.

Winter storm warnings have been issued for central and northern Missouri. These areas are the most likely to see dangerous travel conditions and heavy snow.

Winter storm watches have been issued by the National Weather Service from parts of central and eastern Missouri into southern Illinois, including the St. Louis metro area, southern Indiana and southwestern Ohio.

Winter weather advisories have been issued from much of Kansas eastward into western and northern Missouri, southern Iowa and northwestern Illinois, including the Kansas City and Des Moines metro area.

Winter Weather Alerts

Here is our latest thinking on what to expect from this storm.

Snow, Ice Timing

Friday-Friday Night

  • During the day, snow or a rain-and-snow mix will begin to develop from northern New Mexico, Colorado and southern Wyoming into parts of Kansas, Missouri, southern Iowa and western Illinois.
  • By Friday night, snowfall will become more widespread as it pushes farther east. Areas from eastern Colorado to Kansas, southeast Nebraska, Missouri, Iowa, Illinois, Indiana, northern Kentucky and southwest Ohio could see accumulating snow.
  • Freezing rain may cause slick travel conditions in the Ozarks of northern Arkansas and southern Missouri during the day and overnight.
  • Impacted cities: Denver | St. Louis | Kansas City, Missouri | Indianapolis (night)

Friday's Forecast

Saturday-Saturday Night

  • During the day, a swath of accumulating snow will likely extend from eastern Kansas and southeast Nebraska to Missouri, central and southern Iowa, Illinois, southern Wisconsin, southern Michigan, Indiana, Ohio, West Virginia, western and central Pennsylvania, western and northern Virginia and western North Carolina.
  • Saturday night, snow will continue from eastern Missouri into Illinois, Indiana, Ohio, Pennsylvania, West Virginia, northern and central Virginia, Maryland, Delaware and New Jersey. Light snow is possible as far north as the New York City metro area.
  • Parts of the southern Appalachians as far south as southwestern North Carolina and the adjacent Piedmont could see a wintry mix of snow, sleet and freezing rain.
  • A strip from northern Kentucky to southern West Virginia may also see some icing, potentially causing slick travel conditions.
  • Impacted Cities: Cincinnati | Indianapolis | Roanoke, Virginia | Washington D.C. (late Saturday/overnight)

Saturday's Outlook

Sunday-Sunday Night

  • Snow may continue from the Ohio Valley eastward into West Virginia, northern and central Virginia, southern Pennsylvania, Maryland, Delaware and southern New Jersey.
  • A mix of snow, sleet and freezing rain is possible as far south as western and north-central North Carolina depending on how much cold air is able to drive southward along the eastern side of the Appalachians.
  • The majority of our forecast guidance suggests the storm will slide far enough off the East Coast to prevent significant snowfall from spreading farther north than the mid-Atlantic region.
  • Some light snow could linger into Monday from the central and southern Appalachians into the mid-Atlantic.
  • Impacted cities: Baltimore | Richmond, Virginia | Washington D.C.

Sunday's Outlook

Snow and Ice Forecast

  • A broad area running near and either side of Interstate 70 from Colorado through the central Plains, mid-Mississippi Valley, Ohio Valley and mid-Atlantic should see at least a few inches of snowfall.
  • Heavier totals of up to 6 inches (locally higher) are likely in parts of the above mentioned regions. The area with the greatest chance of seeing those heaver totals right now is from central and eastern Missouri into southern Illinois as well as western Virginia and eastern West Virginia.

Snowfall Forecast

  • Some sleet or ice accumulations are possible from western Virginia into western North Carolina, Kentucky, southern Missouri and northern Arkansas.
