For the past week the models have been showing something happening at the end of November and the beginning of December. What, we don't know just yet. All I know is there is going to be a pattern change to much cooler or colder weather. I think the models are having a bit of a difficult time with how much colder air we will see and if we get any precipitation with the cold air.
I think by Tuesday we should know what we will get in terms of how cold the air will be and if we get any moisture with the cold 🌨
