We're riding the wave between spring and winter this week. And as you might expect surfing such a wave, we'll end up chilly and soaked.
A series of waves of low pressure is moving through this week, starting Tuesday night and today, scooping moisture from the warming Gulf of Mexico up and over the cold air that has descended on us from Canada.
Most of the precipitation this week is going to be rain -- a cold rain, with temperatures hanging in the 30s and 40s, but mostly rain. An inch or two of rain may fall by the time it's over Friday or Saturday.
There could be some snow and sleet this morning, especially in higher elevations and locations north of Roanoke, as the first wave of moisture encounters some temperatures below freezing just above the ground.
The mountains of West Virginia may get nailed by two or three periods of substantial snow this week, and some wind-whipped snow showers are possible in parts of Southwest Virginia late Friday or Saturday as a cold front follows the final wave of rain.
But we're just a little too late on the calendar for much more than that. Seasonal warming is just enough that we'll hang above freezing mostly in a pattern that could have been quite icy and snowy had it been January.
We'll keep riding this wave into the weekend, and perhaps early next week. Then, there are signals that springlike warmth will return and the winterlike cold will get wiped out.
