Denver now has  a high of 36c Monday and 4c to -3c Tuesday. 32c drop in one day would beat most UK extremes for whole year. 

 

Surely if the temperature has been well into the plus +30c for weeks on end how would snow settle? Anyone? Wouldn't the ground be too warm?

Prolonged icy precipitation will soon cool the surface.
I'd be surprised if it's the earliest ever Denver could probably see falling snow in any month though July least likely.

January 2013 I think on 21st we had over 18 hours of snow and nothing settled here in Exeter and on 17th March we had 24 hrs of snow and it only left a trace before temperature fell to -1c and it covered and ended up with 6" of snow well into 19th March.

Crazy for Denver to go from a record breaking high temperature to record breaking September low including early snow but still don't know how people cope with the 30c or so drop in less than 24 hours. with heating off then back on and air con off won't they get sick?

Also looking at Death Valley - temperature high of 53.0c today - I know it's early but September is an Autumn month.

Residents of Denver would be able to have dinner outside in short sleeves at 8-9pm open all doors or close to keep cool and then wake up the next morning to 10cms of snow and -3c. Great

But seriously must be difficult but I would like to experience such rapid change and see how the weather can turn within less than 1 day!? Temperature falling some 2c per hour? Rain starting off as tropical thunderstorms and then as temperature drops from 35c to -3c it just turns to snow and settles!? Would love to experience this meteorological transition I guess.  

A fascinating temperature change one of which I'm sure we'd all like to experience! Must be incredibly odd.

Wild temperature swings of the past decade in Denver
Feb. 24, 2014: In two hours, the temperature jumped from 26 degrees to 57 degrees in the midafternoon. The temperature stayed at 63 degrees until 10:30 p.m. By midnight, it had fallen to 29.
Jan. 5, 2015: 27.9-degree jump, from 12 degrees to nearly 40 degrees in one hour. The same day featured a 15-degree drop in one hour, thanks to a stalled stationary front. After a morning low of minus-4, the thermometer stood at 55 degrees just before midnight, marking the largest one-day temperature swing of past decade. Wednesday’s cold front just missed the mark.
Dec. 9, 2016: 11 degrees at 3 p.m., 53 degrees at 8 p.m.
Dec. 27, 2017: 2 degrees at 2 p.m., 45 degrees by 6 p.m. Two days later, on Dec. 29, the temperature swung from 63 at 8 p.m. to 30 degrees by midnight. The next morning’s low was 9 degrees.
Oct. 9-10, 2019: 82 degrees at 3 p.m., 32 degrees at 10 p.m. Winds gusted to 55 mph as the cold front rushed through, with snow falling shortly thereafter.

You're talking in Fahrenheit!? - I am not good at the conversion but get the jist!

So, September hasn't had falling snow for at least a decade. In fact it was September 2000.

Can't say that I've ever seen a downburst from a #pyrocumulonimbus before.

Terrifying stuff. https://t.co/Fcz7DhHGhT

Goodness me - Just thinking of the wildfires in California and Oregon!?

Looks like the heat is set to stay - look at those record high uppers looking at 18z ENS for LA & Sacramento!?

No rain for the next 2 weeks either!? 

The first major Arctic plunge of the 'Winter' will hit central USA early next week, and will be noticed all the way down to Southern Texas ....

I think Death Valley which currently a record hot October of over 38C 100F days and some 40's days, used to see only once or twice in October now will see big drop in temperatures to 20C early next week so that effects of the cold air in mid-west.

Nice to see this thread back up and 'running'.

Where are the usual guys who use to report on here regularly many years ago on a daily bases - I remember Pete - ExCalgaryMetO, - who reported from Calgary, Alberta - Stuart - Aka Ontario Snowman (reporting from Hamilton, Ontario) and also 'Britbob' - who reported from New Brunswick. Anyone?

Good point Tally. I used to love reading their on the spot reports!
