High pressure in control of the country will provide more people with a partly to mostly sunny Christmas than a white one, with no major storm systems impacting the country.
Snowflakes will fly over portions of the Rockies, with the higher elevations seeing 6-12″ of snow between now and Christmas morning. Lighter amounts of snow will fall over portions of the Pacific northwest, with light to moderate rain showers expected at lower elevations. Light snow is also likely over the Upper Midwest; however, even there, snow shouldn’t cause any major travel issues.
Some widely scattered showers and thunderstorms are possible over the southeast. No wash-out conditions are expected there on Christmas Eve or Christmas Day. This weekend the region will see a soaking rain storm with gusty winds, but it is expected to clear the coast before Christmas arrives.
High pressure will keep roads dry along the heavily traveled I-95 corridor in the northeast; no weather problems at all are expected between Washington, DC and Boston, MA.
