Cool Down Expected in September
No one is going to argue that August’s heat wasn’t brutal. Here in Lawrenceville, there has only been three days when the high temperature has been below 90 degrees, and two of those were at the beginning of the month, before the heat wave got started. In Atlanta, every day has been above 90, more than seven degrees above normal. Normally, Atlanta will only get 36 days with temperatures 90 degrees or higher, and according to some historical data I saw on the National Weather Service website, this may be the longest streak of 90+ degree days ever.
The pattern change that began late last week will finally get temperatures below 90 again, but we may have to wait until September 1st to get there. The movement of the surface and upper-level high pressure systems to our west allowed moist air from the Gulf of Mexico to come into north Georgia, and has been responsible for the afternoon thunderstorms over the weekend. These will probably continue through the week.
By the next weekend, a ridge in the western United States, and a trough along the east coast should cause a northwest flow, which should bring cooler temperatures to much of the southeast. The Weather Service’s long-range outlook from September 1st through 5th calls for cooler than normal temperatures from Texas to the New England States. Of course, everything is relative. I’ll still be happy to see temperatures back towards normal, with highs in the mid 80s and lows in the mid 60s.
