I am loving what I am seeing here in the guidance! This set up screams of winter weather potential, maybe even a storm or two before or around Christmas. If you like winter storms, you want to see this pattern. If you like cold weather, you will LOVE this pattern. Plus, I am getting a lot of observations stating this block is not going away any time soon.
The best part of this 10-day forecast is that this data is supported by observations. In all forecasting, observations should always lead the way. This is why when someone sends me a 300 HR GFS forecast I ask, okay show me the observations that would get you to this solution? What's your trigger? What's the process? In this case, the triggers and process to get from point A to Z is right in front of us and it is so much fun to watch!
