— Flooding is NOT expected today
Warmer and drier is the name of the weather game today, as upper-level high pressure builds in across the western United States. High temperatures will be near normal for the first day of Summer, with skies remaining mostly sunny throughout the day. There exists a *small* chance (less than 10%) for an isolated thunderstorm or two near the eastern CO border during the afternoon hours, but even in the event one forms, it will quickly leave the state, providing almost no impact to Colorado. As the afternoon turns toward the evening hours, a pocket of upper-level moisture will move into the state from the northwest, increasing cloud cover for the overnight hours, especially over the High Country.
