5400 - The First Sign of Snow

By: Buckey2745 , 8:20 PM GMT on September 25, 2013

It's early in the season, but we're seeing our first hint in the GFS of snow for the season. In an unusually early arctic blast, the GFS forecasts... gasp... lake effect snow? The kind of wrap around we see with mid season storms:

Early guesses say the snow stays to our east here in the Columbus area, as the fetch would most likely run from a Cleveland to Pittsburgh line. But still, there's a little excitement at the potential of one of the earliest snows in Columbus' history.

On top of that the GFS calls for a reinforcing shot of cold air about a week later, for what would probably officially usher in colder weather on a permanent basis.

I'll update in the coming days with what the models are doing.

UPDATE: September 26

The latest runs take the lake effect snow out of play, but it's still way too early to rule anything out. Considering we may hit 80 this Saturday, it would be an incredible 7 day swing to see snow the following weekend, but stranger things have happened.

I asked the NWS in Wilmington this morning to confirm our earliest snowfall here in Columbus:

Usually freezing rain and sleet is seen when there's an inversion in the atmosphere. If anything the air aloft will be cool enough, it's the surface that'll be too warm, so we could see some wet flakes that melt on contact possibly... that is if anything at all.

do you think the air temp will be cold enough to snow .. would think that freezing rain or sleet might be what you get if anything other then rain ..
