Summary:
Yesterday was quite the active finale for the weekend with scattered thunderstorms across the state, and stronger storms producing everything in the title of this discussion. West of the Continental Divide noticed a slight downtick in activity over previous days’, while east of the Divide had its most active day in a while. Northeast Colorado (including northern sections of the Front Range/Urban Corridor, as well as the Northeast Plains) saw a few severe thunderstorms, producing hail up to 1-1.5 inches in diameter, strong winds, and a tornado (4 miles ENE of Kersey, Weld County).
Due to the amount of moisture available, all thunderstorms invoked efficient precipitation processes, leading to locally heavy rainfall. While no flash flooding was reported, urban flooding in poor drainage areas was likely to have occurred under strong thunderstorms. A Flash Flood warning was issued for the High Park Burn Scar as heavy rain fell, but no flash flooding was observed/reported.
