East coast heat wave


Slate has an article by Eric Holthaus about the weather:
The Washington Post’s Capital Weather Gang has long been the royalty of internet weather. On Wednesday, they said what everyone already knew: 
It's gross out.
Those three perfectly timed words, coming from a group of meteorologists known more for their in-depth analysis, were exactly what we needed to hear on a day like today.
At fault for the horrid weather, besides the fact that it’s late July, is a weird little storm system moving through southern Canada that’s pulling loads of subtropical humidity northward along the East Coast. That same swirl produced an “exceptional” summertime snowstorm in the mountains of Montana on Monday, along with sixty mph wind gusts. “This pattern should not happen in July,” wrote the National Weather Service forecaster in Billings, stating the obvious. 
Fast forward two days, and parts of more than thirty states are expected to top ninety degrees on Wednesday, including New York City, Philadelphia, Washington, DC, Boston, and much of the West Coast.
Thankfully, some relief is on the way, at least in the East. Once this swirl moves out of the picture by Thursday, humidity levels will drop, alleviating that whole “gross” factor. Still, a recent analysis by Climate Central showed that, in addition to more frequent heat waves, global warming is already making the air more stagnant and sultry on the hottest summer days, contributing to poor air quality. An air quality alert is in effect today for a good portion of the Northeast, from Delaware to Philadelphia to New York City to coastal Connecticut to southern Massachusetts.
Rico says it's pretty gross...
