Heads up! Significant severe weather threat today, particularly this evening, including for the I-25 corridor. A few intense supercells will be possible, capable of producing very large hail exceeding 2-3" in diameter. Be weather aware! #COwx

Preliminary snowfall totals across the Denver Metro area. As expected the bullseye was on NW Boulder/SW Larimer Counties where 20-30" of snow fell. NOTE: Pink boxes mean this May snow event was the biggest of the entire snow season at that location. #COWX #Denver #Colorado

Flatiron Freddy the marmot, our local meteorological savant, did NOT see his shadow this morning in Boulder (thanks massive wave cloud), indicating there will be an early spring. Can spring really come early if winter never showed up in the first place? We're about to find out! Watch the sad news be revealed here (though be warned the audio glitches out in the important parts): youtube.com/watch?v=Hi0UMyi4… #Colorado #COwx #Boulder

Record High Temp today: 71F (old record 70F in 1955). This makes the third record high temperature broken for Denver this month. The record high for Christmas Day is 69F (last set in 2005). With tomorrow's forecast high of 69F, we could see another record being tied or broken.

High temperature so far today in Denver is 76F (old record 70F). This is the second warmest Dec temperature on record for Denver. Warmest Dec temperature is 79F set on Dec 5th, 1939. With temps of 73-79F in the Denver area, we could add a few more degrees to today's high. #cowx

Happy Winter! 10:03am Eastern Time today marked the Winter Solstice, the day of the year when the Earth's northern hemisphere is tilted furthest away from the Sun. This also means that today is the shortest of the year (daylight-wise) for those of us north of the equator. Will wintry temperatures be in your area? 😬 Visit weather.gov to see.

Another impressive list of high wind reports along the Front Range today. Peak gust of 112 mph recorded at the NCAR Mesa Lab, 102 near Niwot, and numerous other reports >80 mph. Humidity at same time was 8-14%! #COwx

It looks as though the🔥Heat Miser🔥has taken over the latest outlook for Christmas week (Dec 23-29)! We are looking at a high probability of warmer-than-normal temperatures for the vast majority of the U.S., with the Plains and South likely trading the Snowman for a Sunburn! The Pacific Northwest, Alaska, and New England have a much better chance of seeing the "classic" Christmas weather you remember as a kid.

It’s officially Denver’s first snow of the season! A whopping 0.2” at DIA = we’re on the board. First measurable snow since April 18 (225 days). ❄️ 2nd-latest first snow of the season (12/10/21). ❄️ 225 snowless days = T-3rd-longest snowless on record for Denver. #COwx
