December is coming in like a lamb in Southwest Virginia, with warm, dry, mostly sunny days. Widespread highs in the 60s are likely in Southwest Virginia Sunday through Tuesday, with some 70s possible at Roanoke and points south and east on Monday and Tuesday. A front arriving at midweek will trim the temperatures back some, to 50s for highs mostly, and back into 20s/30s for lows after a couple mornings that may stick in the 40s and even some 50s. It appears that most of the rainfall will stay north and west of us this week, with perhaps some showers pushing in with Wednesday’s front. While December is beginning mild, cold air continues to build in Canada over a thick snowpack, and it is only a manner of time til some — or a lot — of this cold air oozes southward. A storm system developing next weekend or early the following week may be able to pull a chunk of this Arctic air southward by early next week, but it remains uncertain whether this will be the start of a long-term cold pattern, or at least, a step toward something colder. We’ve only just begun this winter.
