337 AM MDT Sat May 26 2018

.DISCUSSION...
It should be another hot day with scattered late day
thunderstorms developing in the western districts. A few storms
may produce hail and heavy rain. A weather system will then park
itself over the central Rockies Sunday and Monday. This will
result in widespread showers and thunderstorms for the entire
area. Temps will be cooler Sunday/Monday as well. Look for warm
temps and just isolated showers by the middle part of next week.
