Last day before the temperatures crash (back to normal)

Expect another day with temperatures near the 70-degree mark. A front brings showers later this afternoon, and a (not too) drastic cool-down for the middle part of the week.

Hello Tuesday!

Hopefully those folks who love the above-normal temperatures are enjoying their out-of-season warmth... I for one am hoping we don't see many more of these days until March or so. I'm an everything-in-its-season kind of guy, and tis the season for snowfall ;-)

However, we're not going to be seeing anything close to that this week, specifically today. Another northern jet kind of system swings across the Canadian border, giving us the trailing cold front showers. Here's how it looks on the NAM:

NAM - Tuesday PM NAM - Midnight Tues/Weds NAM - Wednesday AM

A quick hitting system that loses steam when it crosses the mountains. Initially there was some thought to the idea that thunder can be a part of this thing, but now it's looking more of an outside shot at best, primarily in KY and southwest WV.

Following the passage of this system, sunshine fills in quickly behind. Humidity levels drop, so we have a nice set of afternoons ahead. However, radiational cooling in the morning will remind us that we are, in fact, still in December.

NAM - Thursday Morning

Dew points sink down into the mid-20s in a lot of places Thursday morning, so expect the kids to have to bundle up (like a December day should). These cold temperatures still don't have much staying power though, because by the time the next system arrives, we'll be creeping above-normal again. This one is lining up for the weekend, but there are some indications that some of this rainfall will end up running north of us, at least at first:

GFS - Friday PM GFS - Saturday PM GFS - Sunday PM

I put the orange arrow in there to indicate the gentle surface wind that will be in play as this system arrives. Not only will this try to inch the temperatures upward, but also push drying air down the north side of the Appalachian mountains and make it more difficult for the immediate downwind areas to saturate to get rainfall. In this scenario, the bulk of the rain would stay just to our north, and maybe hold out of the Kanawha Valley (for instance) until after Saturday's Christmas Parade, even perhaps until Sunday. That's not all bad, right? There's still some flux to this, but one thing is for sure-- it's not going to be snow :-/
