NOAA released their updated Three Month Temperature and Precipitation Outlooks on June 20th for the months July, August, and September 2019. From the charts below, you can see both coasts in the contiguous US have the highest probability of above-average temperatures over that period with more seasonal/below average temperatures expected for the rest of the country. The Precipitation Outlook does show some relief to the very wet Spring/Summer we have been having. Most regions look to see near average precipitation levels with the highest probability of rain expected in the Rockies and western half of the Midwest. Follow the link below to NOAA’s post.
