Thursday's gloomy Seattle weather was nearly unique in its monotony

SEATTLE -- Thursday's thick, dark overcast with occasional light rain may not have seemed out of the ordinary for a November day, but believe it or not, it managed to do something fairly rare.

With a high of 44 and a low of 42, it was only the 27th time since 1950 that Seattle's had an entire day with only a two-degree temperature spread!

Joe Zagrodnik, a graduate student at the University of Washington, compiled all of Seattle's highs and lows since 1950 to find the somewhat unique correlation.

Only three days since 1950 have had just one degree spread -- all in January and all likely on a similarly thick, gray day: Jan 23, 1971 (44/43), Jan. 28, 1974 (45/44) and Jan. 13, 2014 (51/50).

But at least the low of 42 was not surprising. In fact, Zagrodnik says it's the most common low temperature in Seattle, typically paired with a 53 degree high. Seattle has had that 53/42 day 105 times since 1950.
