Enjoy this fall warmth while we've got it. Tomorrow will be warmer than today with highs in the lower 80s. There's a mighty Arctic front heading our way that will bring the first big chill of the fall. Temperatures will drop 20 to 25 degrees by Saturday! Temperatures will struggle to climb above 60° once the front crosses. The chilly air mass will also bring the first chance for frost Sunday morning.
This front is already causing trouble across the Rockies and northern Plains. Up to three feet of snow plus blizzard conditions are possible through Sunday for parts of the Dakotas. The front will march through the Bluegrass Friday night and weaken in the process. A few showers and thundershowers will be possible through mid-day on Saturday. Skies will gradually clear into the second half of the day.
