Across Colorado, a solid plume of monsoon moisture still resides over the state. With this, we’ll be in store for another round of potent afternoon thunderstorms today, just like the past two afternoons. The narrow plume of moisture, tracing back to the Gulf of California, is seen in the precipitable water anomaly map below.

Expect highs to soar into the mid 90’s by mid-afternoon before clouds and storms build in. Storm coverage will be similar, if not slightly reduced from yesterday. We’re still looking at about a 30% chance for everyone across the region.

Enjoy the rains…. they look to continue (though slightly less widespread) right through the upcoming weekend!
