The best bet for outdoor plans will be to get them done today or tomorrow. The risk of showers increases Thursday and Friday in time for high school football.
We are between storm systems today. Warmer air will pump up from the south tomorrow and Thursday as a low pressure center develops over western South Dakota and eastern Wyoming. There could be a random thunderstorm tomorrow afternoon, but the better chance will be Thursday with isolated showers and thunderstorms form. The best chance will be Friday as the low moves off to the east and cooler air pulls down from Canada. The weekend should be very pleasant.
This is, of course, the autumnal pattern: A gradual cool down marked by wide swings in temperature every few days. We'll see fewer and fewer days with afternoon highs in the 80s as we get into October and an increasing number of frosty mornings.
Look for sunshine today with highs of 70-75. Tomorrow's sky will be dotted with clouds and there is a small chance of a late afternoon or evening shower as winds pick up from the southeast. Highs will be 77-82.
There will be a good chance of scattered showers and thunderstorms Thursday. Highs will be 75-80. Scattered showers will linger for Friday with a high of 68-73.
