Hear me now, believe me later. We will see a "cool down" next week. Climatology shows that we typically get a "cool snap" at the end of September into early October.
The overall pattern shows the big chill may come next Wednesday on October 1st. Write it down and see if I'm right.
The GFS is advertising 850mb temps to be at about -2°C. That's the temperature at roughly 5,000 feet. If you crunch some numbers, that would translate into some upper40s for some of us for overnight lows!
Let's see what happens!
