My friend Bob, who knows more about math and computers than any human safely should, created this loop to show the cold air moving into the Plains and toward the East Coast. The colors depict temperatures.
As he pointed out, earlier this afternoon there was a 50° temperature difference between eastern and western Iowa.
Even without knowing meteorology this map is impressive.
Mesmerizing. Would love to see a longer term version of this.. a week, a month? Really nicely done.
In the first hour after the front passed through here we dropped 22 degrees.
Yesterday we hit 47 degrees. Right now it’s 7.
