You should look at what happens east of the Rocky Mountains…
Denver had a 66 degree F drop in just 24 hours.. From a high of 82 to 16 degrees just 24 hours later and snowing.
That blue cold northern that happens when a very strong arctic front pushes down and south along the front range of the Rocky Mountains is incredible.
Then the warm down sloping Shinook winds can raise temperatures 40 to 50 degrees in very, very short periods of time too. I think the record for warming up was somewhere in Montana I think where it went from -4 F to 47 F in like 10 minutes…
A 51 degree temperature change in hardly no time.
One time in my area it went from 33 degrees F at midnight and warmed up to 65 degrees F by 6 am… That was incredible. We had a bit of snow left on the ground from a snowstorm a few days before. And it was melting as fast as possible and it was night time and dark out. Temperature was rising all night long. Pretty impressive and shocking. I drove on Rte 199 near me when it first started warming up and the temperature at the top of the hills was near 41 degrees F and when you got to the bottom of the hill it was 34 degrees F. And the elevation change was only 40-50 feet. Very interesting to see that happen like that. Took awhile for the warmer air to scout out the colder air in those slightly lower elevations.
