Lots Of Winter Ahead…After a brief weekend thaw, winter’s set to roar back with authority this week. Morning freezing drizzle and freezing fog should diminish and give way to a mostly cloudy day. It’ll be much colder than what we enjoyed over the weekend as temperatures hold nearly steady through the day.
Sunshine returns briefly Tuesday, but another fast-moving weather disturbance will bring a light rain shower Wednesday. As a shot of arctic air drills in here Wednesday night and Thursday, snow showers will blow into town with gusty winds.
A second and even more intense surge of bitter arctic air will pour south Saturday into Sunday. Dangerously cold air will be accompanied with this surge, including below zero wind chills and more snow showers.
We’re eyeing early next week for the opportunity of a more widespread winter event. Stay tuned…

Not A Bad Day Today; Snow Event Wednesday…After a cold start today, temperatures will moderate into the lower to middle 30s this afternoon. We’ll be in a weak southerly air flow this afternoon as a disturbance tracks to our north.
The big focus of this forecast package has to do with Wednesday. We forecast a quiet start to the day, but clouds will quickly lower and thicken and widespread snow, briefly heavy, will overspread all of the region tomorrow afternoon. This will be a dry, powdery snow as all of the snow will fall behind an arctic boundary that will slip through the region. As of now we forecast 2″-3″ of snow tomorrow afternoon into tomorrow evening. Strong and gusty north winds will lead to blowing and drifting issues Wednesday evening. All in all, expect the Wednesday evening rush to be impacted. Frigid air will settle over the region by Thursday morning with dry conditions returning.
Temperatures will slowly moderate briefly out ahead of our next weekend weather maker. Keep an eye on Sunday-Monday as that will be our next opportunity for accumulating wintry precipitation.

Models are handling the arctic front and associated wave differently from one another, but we tend to favor more of a GEM/ European blend. As it is, even the GFS is beginning to see the snow threat. The NAM (below) sees snow overspreading the region Wednesday afternoon and evening.
This is a different set-up than anything we’ve seen this winter as the majority of precipitation develops on the backside of the frontal boundary. An “ana front” is one that features clouds and precipitation developing behind the frontal system. The air behind this boundary will be of arctic origin and lead to very high snow ratios- meaning it won’t take much moisture to “fluff” up a few inches of snow across the region. Strong and gusty winds will also develop Wednesday night and temperatures will plummet (single digits or below zero Thursday morning). Blowing and drifting will be a concern. Stay tuned as we continue to look over the data.
The other item on the agenda has to do with Sunday. Once again we’ve got another major model battle on our hands. Taken verbatim, the GFS would imply a relatively boring weather weekend with some clouds and light rain (possibly ending as light snow Saturday night into Sunday). On the other hand, the European model implies a winter storm threat for the Ohio Valley Sunday….
Needless to say, there’s a lot going on and despite the headaches of last weekend, we may be back in a similar position for the upcoming weekend. And you thought you wanted this job?! 🙂
