Moderate to heavy snowfall is expected on Wednesday across portions of the Southern Rockies and High Plains. Light to moderate snowfall is possible for the Mid Atlantic, specifically from West Virginia to Delaware.
Mid-Atlantic: The clipper system will Push from the Ohio Valley to the mid-Atlantic coast on Wednesday, allowing for light to moderate snowfall across the region. A more southerly track is forecast for the low pressure system compared to yesterday’s forecast, and as such the greatest risk for 2 to 4 inches of snowfall has shifted more into West Virginia, northern Virginia, Maryland, and Delaware, with a secondary risk area in eastern Ohio and western Pennsylvania. Eastern PA, New Jersey, and the NYC metro region are now expected to receive under 2 inches of snowfall, and coastal New England may escape unscathed or only with very light snow. Very light and patchy icing is possible between Washington and New York, but any icing should quickly change to snow.
Southern Rockies & Southern Plains: An upper level low moving across the Southern Rockies into the Southern Plains on Wednesday will allow for light to moderate snow to develop across southeastern Colorado Wednesday morning, then shift south and southeast into eastern New Mexico and the Texas Panhandle during the afternoon and night. Snow totals of 3 to 7 inches will be common across the area, but higher totals, up to 10 inches or so, are certainly possible across northern and northeastern New Mexico. Any icing prior to changing over to snow, mainly limited to portions of the Panhandle and eastern New Mexico, should be fairly limited and light.
