After a not-so-hot start to August, a heatwave with multiple days of temperatures near or just above 100 degrees will be possible by the end of the workweek through the weekend.

An upper-level ridge, or an area of high pressure, in the middle of the atmosphere will expand farther east over the ArkLaTex late this week and will be planted over the ArkLaTex this weekend.

Expect a ton of sizzling sunshine and temperatures near 100 degrees Friday through early next week.

With more heat and little to no rain, drought conditions likely will worsen across the area.

The latest run of FutureTrack shows afternoon highs near or just above 100 degrees across most of the area Friday, Saturday and Sunday. A few places could top the century mark.

The average high Aug. 24-26 is 94 degrees. So temperatures will be well above average for this time of year.

It's a little to early to tell if we'll break any records, but we could be close.

Record highs in Shreveport

  • Aug. 24: 103 degrees (1899)
  • Aug. 25: 103 degrees (1881)
  • Aug. 26: 105 degrees (2011)

The air is not only going to be hot, it's also going to be humid.

Heat advisories or warnings about excessive heat could be issued later this week or this weekend.

If you plan to spend a lot of time outside this weekend, make sure you beat the heat.

With the heat and humidity scheduled to crank back up in the ArkLaTex, make sure to enjoy Wednesday afternoon.

Even though it's still going to be hot, temperatures will be near average for this time of year.

Plus, our humidity levels will be low. The lower humidity levels will help take the edge off the heat.

The KSLA First Alert Weather Team will continue to be your First Alert on the potential for dangerous heat later this week and this weekend.
