Quick spotty showers blowing through early this evening. Few rumbles possible, mainly east of Denver. The cold front will come in later, then πŸ₯Ά for the rest of the week! #cowx
⚠️ FREEZE WARNING for the next two nights in the Boulder-Denver area. Going down to ~28° tonight, with lower 20s Tuesday night. You can get away just draining above ground pipes (backflow) tonight, but we recommend fully winterizing your system before Tuesday night! #COWX

Nice little low pressure spinning across southern Colorado this afternoon, providing upslope flow aloft over Denver. Too bad the storm is so small, weak and lacking moisture. Soon enough we'll get a real autumn upslope storm.... #COWx
Boulder had its first freeze of the season Tuesday morning dipping to 30 degrees.

This is just one of several milestones as we transition deeper into autumn towards even colder weather and eventually snow!

Who's ready? β˜ƒοΈ #COwx #Boulderwx #Colorado #Boulder
Yeah this is a rough estimate map. There were mixed obs in your area some just below and some above.

Our station got down to 31.2 Sunday morning. Today was warmer at 33.5.
Remember frost doesn't necessarily mean that you were below freezing. It only means the ground surface was below freezing.
Based on the latest temperature data from this morning and Sunday, there are still some parts of the #Boulder-#Denver Metro area that have NOT dropped below freezing yet.

Are you in one of the "lucky" neighborhoods? #COWX #Freeze
Some peak obs...

Boulder Airport: 44 MPH
NCAR Mesa: 55 MPH
DIA: 44 MPH
NREL Wind Site: 69 MPH
Rocky Flats CDOT: 73 MPH
πŸ’¨ Peak wind gusts so far thru 10AM Monday. Widespread 30-45 MPH gusts, locally 50-60+ MPH

⚑️ Xcel Energy is reporting some outages (~10k customers in Metro w/o power). No planned power cuts were enacted for fire safety

πŸ”₯ Winds will remain strong into the afternoon w/ near-critical fire risk #COWX
FYI: A huge global Amazon Web Services outage is impacting some aspects of our site and preventing our weekly Monday morning email from going out. Hopefully this is resolved soon but we have no ETA. πŸ’₯
