Why does New England get so humid?
Some of the warmest water temperatures relative to normal are just offshore of New England in the Western Atlantic. Warmer water leads to more efficient evaporation and, ultimately, more moisture in the air. Stagnant areas of high pressure have helped hold the steamy air in place.

Why is Western America so dry?
The reason for the extensive drought is two-fold; long term drying fueled by human-caused climate change and, in the short term, a La Niña event in which cool Equatorial Pacific waters failed to fuel an ample fetch of moisture. Consequently, this past winter’s wet season was not very wet at all.
