Might there be some snow in the air this weekend? AccuWeather's extreme weather blogger Henry Margusity thinks so. He's looking at a fairly intense storm brewing in the Rockies and predicting it will become a strong coastal storm by this weekend. He thinks it will barrel up the East Coast, knock into some pretty cold entrenched air here and drop some snow and ice on the mid-Atlantic on Sunday before everything changes to rain.

If he's right, it would be the first significant winter storm of the season. It would also reinforce some of the seasonal forecasts that predicted most of our wintry weather this year would come in December, to be followed by a very mild "La Nina" January and February.

If he's wrong, it would provide brickbats for those who see Margusity as a conduit for winter weather scares and hype, of the sort that boosts online traffic counts. And here I am, contributing to that.

Anyway, he says he'll be posting a snow map forecast at 8:30 tonight. We'll just have to wait and see how well he does with it.

In the meantime, our NWS forecasters out at Sterling, Va., looking at the same model pedictions, think the storm will move up the Ohio Valley rather than reforming offshore and coming up the coast. That would give us warmer temperatures. They see rain falling on Sunday, after an overnight low of 28. They're posting only "snow showers" for Sunday night. The chances for either rain or snow are put at 50 percent.

CapitalWeather.com has this take on the snow threat, which they give only a 20 percent shot: "Minor Event -- Some accumulation. Untreated roads hazardous, slick spots possible on treated roads during heavy precipitation. (Winter weather advisory criteria, dusting to two inches)"

Everybody is looking for sharply colder weather later next week.
