Big time brrr!
No, seriously. A low aloft is funneling cool air from up north down on top of us through today, and as a result, we're forced into much cooler straits for a few days; it started late last night with a base cooldown, but even the sun can't help us along for today. There is the chance for some light flurry activity for today and tomorrow, but don't expect more than a couple of centimeters, if any.
