Continental U.S. had warmest May on record, NOAA says
The National Oceanic and Atmospheric Administration or NOAA said that this was the hottest May on record in U.S. history. This was due a to variety of factors. One was being that the jet stream was position more northerly than normal. This allowed a heat ridge to sit over the mid-western United States. A study has also come out that shows hurricanes are moving 10 percent slower. This means more storms like Harvey from August of 2017 which dumped a tremendous amount of rainfall.
