| 24 hr Max/Min: 80/53 ; Peak Wind 36 // Mostly Cloudy. CBs/T-storms developed early-mid afternoon over the Front Range/foothills and moved NE. The southern end of the line missed Milliken with a outflow boundary producing a gust of 36. It generated a shower over Johnstown/Milliken ~1745-1805. I observed sprinkles again @ 1915L. A line of t-storms developed to the S ~ 2000L with lightning strikes within 7 mi to the S-E, no thunder was observed and no rain on station as it moved NE along US 85.// |

| Spitting rain 9:30am, showers 3-3:15pm, rain off and on from 3:30pm til 3:45, then heavy rain with what may have been tiny hail and a single lightning-thunder pair. Rain continuing, fairly heavy, now with multiple claps of thunder, some even nearby, and almost continuous. Heavy rain with wind continues with locally flooded streets (overflowing culverts only) and occasional tiny hail. Sun emerges at 4:20pm while heavy rain continues, with distant thunder heard. Slows to a light rain by 4:25pm, distant thunder still quite loud and persistent. Ends at 4:35pm as storm heads to the east and sun is out. Gauge measures 0.43”! SigWx form submitted :) |

We had another shower later. Our high temperature was in the 50's and our current temperature is 36 degrees with a clearing sky. Our weather feels more like September and fall. |
