Colorado Springs area

Mid to late June is a bit early for the regular monsoon moisture flow that typically starts in July. However afternoon isolated or scattered thunderstorms sure wouldn't be out of the question at all. Temps can be anywhere from mid 70's to upper 90's that just depends on the weather systems in place at the time though mid to upper 80s is probably the average. Not uncommon for their to be a 30+ degree temp swing between the high and low of the day. There can be what they call high based storms in the afternoon which means typically high wind while the storm passes by with little to no rain as it evaporates before it hits the ground. And then on other hand it could dump for 20 minutes with an inch or two of hail on the ground. Just like many other places if you don't like the weather check again in a few minutes it may be different.
Expect nice weather but be prepared for high winds(ie dont leave your awnings out if you are not going to be around), rain (ie have rain gear with you if you are out hiking) and hail (expect none but dont be too surprised to find yourself in a hailstorm).
