What you notice right off the bat is the disturbance in the southwestern U.S. This storm would then ride northeast toward the Great Lakes on that fast flowing jet streak moving directly toward Chicago out of the desert southwest. This setup is a perfect example of what we see typically in La Nina years. The really bitter cold Winter air is bottled up in the northern tier, while the southeast is seeing warm conditions because they are south of that jet. The Ohio Valley lies right in the war zone. This pattern is why we see a storm system roll through every week, but it is also why we won't see snow anytime soon because it's keeping the cold air held north of us.
That ripple, or dip in the jet that you see moving into western Texas on this chart will eventually move through the Ohio Valley... this will drop our temps after the front passes and give us some rain. Then a couple days later the chart will look just like this again and Kentucky will be basking in 60s. It's a broken record, and it looks to me like it will be the rule in November.
I would strongly caution people to keep in mind that this is exactly what we dealt with last year. October was gorgeous. November was a rollercoaster of ups and downs. Then in December the bottom fell out and it was full-blown Winter here. I'm not saying that it's going to happen again this December.. but it's a distinct possibility that when the dam breaks and that cold air bottled up in Canada does finally drop in, it might come in with a vengeance.
For now, enjoy these nice Fall days we are seeing in November. It is, afterall, the month of Thanksgiving for all God has created and all He has blessed us with.
