Millions of people will be hitting the roads and skies this holiday week and with the ever changing weather it can cause headaches for those trying to reach their holiday destinations. Here’s a quick rundown of what you can expect:
Wednesday’s national forecast appears to be a smooth ride for many as the majority of the lower 48s will be dominated by a rising high pressure system. It will likely remain under control for much of the eastern half of the United States heading into Thursday. A brief short wave will likely bring a rapid expanse of snowfall north of the Twin Cities and closer to Duluth Thursday night as it straddles the north side of the departing high.
To the west, a continuing train of low pressure systems straddling the northern extent of an Alaska High and crossing the BC coastline will continue to present sloppy conditions for much of the Pacific Northwest, as rain and snow are likely.
Christmas Eve (Friday)
The high will move further south over the Florida peninsula by Friday morning presenting calm conditions. This high however will redirect the rapid eastward low wave trough that will bring snowfall north of the Twin Cities on Thursday evening. It could be a brief headache for parts of New England as travelers depart on Christmas Eve morning when the system arrives. Improved southerly winds locally will allow temperatures to rise into the mid 40s.
Back west, no change is expected as a continuation of rain and winter mixing will likely continue in areas like Seattle, while rain showers and high-altitude snowfall will continue in California. . That same moisture will then enter the Rockies and slowly become a sight for us here at home to watch on Christmas Day evening.
Christmas Day (Saturday)
As snow and rain continue to plague the west, this moisture will seep into the Rockies and head into the upper Midwest where we could be talking snowfall on Christmas Day evening. While snow amounts and forecast verification are not yet certain, it will be something to watch. This same system will then work eastward and arrive in the northeast early in the morning of Sunday 26th.
