From LWX:
.LONG TERM /FRIDAY THROUGH MONDAY/...
From Friday through the weekend and into early next week, the
hemispheric pattern does not appreciably change. More
specifically, this features an upper ridge over the eastern
Pacific, another high near the Bahamas, and a deep upper low to
the north of Hudson Bay. Split flow is evident in the guidance
which carry waves across the western U.S. as well as within the
cyclonic longwave flow regime over the central/eastern U.S. At
this juncture, there is little to no interactions with these
streams which is often the recipe for a more pronounced winter
weather threat.
You can tell that LWX is a little baffled at how this winter is going, huh?
