Our First Taste Of Winter?

It was bound to happen sooner or later, and if the latest model runs hold true, our first taste of winter weather could fall under the "sooner" category.

European Model - Tuesday Morning
A couple of model runs have a strong area of low pressure passing just to our south next Tuesday. The European model has been pretty reliable as of late and shows the center of low pressure just off to our southeast Tuesday morning.

GFS Model - Tuesday Midday
The GFS model shows a similar path. While the heaviest of the precip with this system would stay closer to the Gulf states, we could easily see some precip of our own.

GFS Model - Freezing Line for Tuesday Midday
Here's where things get interesting. The GFS has the freezing line for this system just off to our south. Everything north of that line has plenty of cold air aloft to support snow. What does that mean for us? In short, a couple inches of the white stuff. That's if the models don't change between now and next week... and that's a BIG if.

Some models show this system staying south. Here's the general rule as we head into next week. The further south the low moves, the less chance we have of seeing anything. The further north the system moves, the messier things could get for us. Stay tuned!
