Record heat has dominated the weather across the Southeast this weekend, and a couple more days of it is ahead as we get into the weekend. The reason: a very strong ridge of high pressure stalled over the Southeast. This high pressure will keep much of the region warm as well as dry due to sinking and suppressed air aloft.
On Saturday, widespread high temperatures in the 70s and 80s is likely. Major cities that will be in the 70s includes; Little Rock, Nashville, Raleigh, Charlotte, and Atlanta. Even more cities will experience high temperatures in the 80s. That includes: Columbia, Charleston, Savannah, Jacksonville, Tampa, Miami, New Orleans, Birmingham, and Jackson. Many of these cities that we have mentioned are also expected to either tie or break their record high temperature. In fact, nearly two dozen climate stations in the Southeast are expected to achieve a new record.
Record warm low temperatures will become even more widespread Saturday night or Sunday morning. With record warm low temperatures, it means that there has never been a low temperature as warm as the current record. Over three dozen climate stations are forecast to accomplish a record warm low temperature. These records will be widespread across the Mid-Atlantic, Carolinas, Georgia, Alabama, and Florida. Most of these locations will experience low temperatures in the 60s, but in South Florida it will be in the mid 70s.
The record heat will stick around on Sunday, although it won’t be as prevalent. Only about half a dozen record high temperatures are forecast to be either tied or broken. This includes: Wilmington, Charleston, Savannah, Jacksonville, and Gainesville. As you may tell, the record heat will remain confined to the Atlantic coast, and this is where temperatures will range from the upper 70s to the mid 80s. It may even get into the upper 80s across the interior Florida Peninsula. For the rest of the Southeast, it will be slightly cooler but still above average with highs in the 60s and 70s.
Looking ahead to next week, temperatures will remain up to twenty degrees above average, although record-breaking heat is not expected. For most days during the week, high temperatures will be in the 60s, 70s, and 80s.
