@BarnettMPH @madbeatboy @Weather_West If you are a federal employee, the mandate was to show up to work in your office. Only 6% of federal employees followed the order. I didn’t make up the rules. Don’t show up, get fired for insubordination. It’s not rocket science. It’s a new boss.

BTW, if you work in the weather/climate/disaster/emergency management space and are/were a federal employee who has been fired in recent hours/days, there are multiple journalists interested in speaking to you (and will be watching replies on this thread).

Note there have been several station moves in the >120-year history of the Boulder COOP, so these Tmins aren't quite apples-apples. But 1/16-17/1930 was indeed super-cold; all-time Tmins at Longmont (-38) & Kassler SW of Denver (-32), and #2 at Fort Collins (-38)

On this date (1/17) in 1930, the Boulder COOP station dropped to -33 F, the all-time record Tmin. The Tmin at Boulder yesterday was -14 F -- plenty frigid, but it barely makes the 50 lowest Tmins since 1893 (see table). COOP data: SC-ACIS scacis.rcc-acis.org

@mdettinger I just noticed that last week. Appalling to see important state-level climate-change planning docs get not just ignored but *scrubbed* by a new admin, making them unavailable to anyone. As you say, a big step backwards for NV.

Nevada is backsliding on climate change (I can attest to this personally). Current governor has replaced its preexisting Climate Action Plan with an "Under Construction" symbol, with no signs of action/reconstruction in the community. thenevadaindependent.com/article/govern…

@CReppWx @farflungfoodie @9NEWS @NREL Agree that nearly all cars and trucks have been "supersized" in recent years. I was surprised to learn that my EV (VW ID.4)--which has a hefty 4900 lb curb weight--was only slightly heavier than my BIL's "normal" 2023 Ford Explorer (4700 lbs).

@farflungfoodie @9NEWS @NREL Good point. I know that a small electric car now outweighs the big SUV's and trucks of yesterday. But you're right, it does seem like we've been adding a lot of weight to our roads and bridges for a while now.

@LukeRunyon Fun fact: Historically (1895-2022), there is zero correlation between Oct precip in the Upper Colorado Basin and precip over the rest of the snow season (Nov-May). Having a decent amount of snow by the end of Oct is helpful (assuming it sticks around), but not very predictive.

@Dendrogobbler Yep, I've seen this in old (300-700 yr) Doug-fir in Colorado, at least a handful of times.

Any dendro folks experienced this? Fungus of some kind growing in the interior of Doug fir. This was in northwest Yellowstone

@CReppWx @BoulderCAST Several years ago, NRCS switched from the average to the median as their default "normal." I'm guessing that the text on their map that says "average" is a holdover from before. The legend (median) is correct.

@BoulderCAST They probably use median but say average in conversational context , kind of like we do in the media

Statewide snowpack is off to a decent start at 565% above normal. Of course, our average is next to nothing this time of year, but it certainly gets your attention haha #9wx

@LukeRunyon @KUNC Specific to the Colorado River, you've done a great public service in clearly conveying the nuts, bolts, and devil-in-the-details of some very complex issues. Appreciate all your hard work.

@Protons4B @micefearboggis Thanks for sharing your 'personalized' GMST time series--that's a compelling way to depict the human scale of change. The depiction of your own lifespan brought to mind this Stephen Wright joke: "I know when I'm going to die. My birth certificate has an expiration date on it."

Colorado has warmed over 2 degrees F in the past 40 years, impacting water supply, water demand, wildfire risk, ecosystem resilience, and much more. #ShowYourStripes ShowYourStripes.info

@KeithJGw @ParkCounty Thanks @KeithJGw--the fire perimeter released last night confirms that the 1700 asterisk was correct, but the *1500* asterisk was too far west. Totally understandable given the winds/terrain/smoke--impossible to locate the head of the fire at that point.

Update at 5:30 PM - the latest map is included below. It shows the evacuation area in purple and the new fire location, approximately 1/2 mile from the Teller County line. parkco.us/civicalerts.as…

Do you need climate-change information for local decision-making in the West (or elsewhere)? Check out this resource! And let us know if it's helpful, and how we can improve/update it. (Julie Vano of @aspenglobal and I developed it; funding: @NOAAClimate & @aspenglobal)

There are a lot of climate portals available. This "User Guide to Climate Change Portals" provides practical guidance for navigating the landscape of climate change portals and resources to find what you need. toolkit.climate.gov/tool/user-guid…
