Another very warm day will unfold on Tuesday ahead of an approaching backdoor cold front, which is a front that advances from the northeast.
Temperatures will rise into the middle and upper 80s, falling just short of Tuesday's record high of 90 F from 1944. It will remain sticky, setting the stage for the front to trigger showers and thunderstorms.
In the wake of the front, shorts and sunglasses will likely be replaced with spring jackets and umbrellas on Wednesday.
