Synopsis – TUE SEP 23 2025

High pressure will bring on mostly sunny skies and temps a bit above normal. But by mid week, a cut off low off the CA coast shifts inland, as current high pressure moves into the N. Rockies. This will bring some moisture into our area and give us chances of showers and t-storms. Precipitation chances look to run some 30 – 40%, particularly over higher terrain, Wednesday and Thursday.
