Snow hit us early in November just like it did in the previous winter of 2018-2019. But since then, December had above-normal temperatures and below-normal precipitation.

  • Glenn Zimmerman’s long-range forecast for fall 2019

    September: September is never really a Fall month. The first two weeks are always warm, much more like the summer heat and humidity most years. This year, I think September starts off on the unsettled side. Look for rain to be prominent in the first two weeks. The Tropics, which have been mostly quiet this summer, will start to come alive.
