Good Thursday evening. Our warm front made it’s way across the state a little earlier today with a few showers. Temps soared once that front moved northward with everyone hitting the 60s. Not too bad. The weekend continues to be the big ticked weather deal as far as the forecast goes.

In the short term… we will be seeing a mild night with most areas staying in the 50s. Those 50s will be with us into the first half of Friday before dropping quickly through the 40s by later in the day as our front moves through. Showers and even a few thunderstorms will be with us later tonight and Friday.

The weekend storm continues to take center stage. The models are still trying to get a handle on the EXACT track of the low and they won’t get nail it down until later Friday in all likelihood. It is all about the evolution of the closed upper level low as to whether we are shoveling a heavy wet snow or watching most of the snow pass us by to the south and east.

We are getting close to the time that the NAM model becomes something to really watch. The latest run of the NAM looks a lot like some of the recent runs from other models. It is farther west and stronger with the low…

That is a storm that produces it own cold air on the northern and western side of the low (Dynamic Cooling) so one should not pay a whole lot of attention to the 0c 850mb line. Check out the snowfall map from this run of the NAM…

Nam Snowfall Forecast


The green is 4″… the white is 6″ while the blue shows 8″-10″. This run looks like an earlier run from the GFS from very early this morning…

6z GFS Snowfall Forecast


Those two model runs are the farthest west of the day. That does NOT mean they are right by any means!! The latest runs of the GFS have shifted a bit farther east and southeast…

Saturday Evening


The GFS does have a bias of being too far east with surface lows in the eastern part of the country. That said… it does have support from some of the other models. Still… it is printing out several inches of wet snow in the south and east.

If the seasonal trend holds true… one would expect this storm to continue to come farther northwest. I say IF because the setup with this is one that can miss us mainly to the south and east. The is no forecasting room for error with this storm and I am seeing some forecasts out there that just blow my mind because they aren’t looking at the possibilities with this thing.

Even the folks at the NWS’s HPC are outlooking parts of the region for a possible snowstorm…

Saturday


Sunday

They are obviously taking the new run of the GFS hook line and sinker.. but that is more than some folks are doing!

So, what is going to happen this weekend? I wish I could tell you, but I am trying to outline the possibilities for you guys. Anybody attempting to say this is EXACTLY what will happen is just asking for trouble!!!

I will have another update for you later tonight and this MAY include an upgrade to THREAT level. We shall see.

Have a great evening and take care.
