Winter Storm Olympia is continuing to spread snow and create dangerous travel conditions, with snow and icy rain mixes covering the eastern U.S. on Monday. Over the weekend, several multi-vehicle accidents occurred in the Midwest as a result of the storm, according to The Weather Channel.

Hundreds of flights have been canceled due to snow and ice in the Tennessee Valley up to Washington, D.C., according to Accuweather.

Precipitation in the East should start as snow or ice but will most likely change to rain as the storm persists. A low-pressure system moving inland from the South to the Northeast should warm the air in the region along the I-95 corridor.

Boston, which saw temperatures as low as -9 on Sunday, should see temperatures shoot up to the mid-50s with rain Tuesday, reports The Weather Channel.

Monday will bring snow in the mid-Atlantic, but it will change to a wintry, sleet mix. Snow can be expected up to the Lower Hudson Valley and southern New England, according to Weather Underground. Moisture will beat out subfreezing air by the surface, causing freezing rain and sleet for some time in southern New Jersey and southeast Pennsylvania, out to Virginia and most of North Carolina. Sleet will also come down on northern South Carolina and northeast Georgia.

On Monday, the arc stretching from northern Maine, southwest along the Canadian border to western New York, northwest Pennsylvania and northeast Ohio will see the most snow.

Ice has the penitential to linger Monday evening from northwest North Carolina to western Virginia and other parts of the mid-Atlantic before changing to rain, but by Tuesday most of the East should warm enough for it to have changed to rain. Temperatures will be in the high 40s to the mid-50s across the mid-Atlantic.
