A soaking rain fell across much of the Denver Metro area yesterday thanks to a cold front teaming up with monsoon moisture. Numerous weak storms moved from the higher elevations eastward across the Plains. While they had a good pace of movement, precipitable water values near 1.5 inches across the region led to heavy bursts of rainfall at times. We cautioned that …

Both the NAM and GFS models are quite optimistic for seeing widely scattered thunderstorms across the Metro area today. We have the chance of rain at 20 to 30% region-wide. The main driver is a small-scale shortwave embedded in the northwest flow. This wave, while fairly weak, will be well-timed with afternoon solar heating across northern Colorado. After low clouds and …
