August 22 – Weather forecast update for Shreveport, Texarkana

There will likely be seven straight days of record heat and then some relief

ArkLaTex will continue to see near-record temperatures through the end of the week. A front will move through the area on Sunday and bring a slight chance of rain. More normal temperatures return behind the front next week.

Current temperatures around ArkLaTex

Dangerous hot weather continues: We saw a new record high temperature in Shreveport on Monday with a high of 107 degrees. Don’t expect much change over the next few days. The record highs between now and Sunday are as follows: Wednesday: 106, Thursday: 103, Friday: 103, Saturday: 105, and Sunday: 103. There is a good chance we will see all of them lower. If that happens, it means we will see seven straight days of new record heat. Temperatures will likely start Wednesday well above normal with lows in the 70s and 80s. Daytime highs on Wednesday will once again reach 105 degrees across much of the region. Expect the heat index to remain an issue during this period and remember to protect yourself from potential health issues caused by the heat.

Tomorrow’s forecast

Continuing dry weather: Although Tropical Storm Harold is over far southern Texas, dry weather in the ArkLaTex will persist. Futurecast shows we will see mostly clear skies tonight. Expect plenty of sunshine again on Wednesday, clear to partly cloudy skies Wednesday night, and plenty of sunshine again on Thursday. We could see a very small chance of pop-up rain starting Friday, but rain chances will be very slim as most of the area will remain dry.

Finally, more normal temperatures: The large area of ​​upper-level high pressure that has caused extreme heat over the past month is now centered to our north. It will approach us on Thursday and then end up over the Rocky Mountains. The hottest days ahead are likely to be Thursday and Friday. Highs will likely be in the 105 to 108 range around the area. The all-time record high in Shreveport is 110. We probably won’t see temperatures that hot, but that can’t be completely ruled out. As the ridge moves west, upper level winds will become more northwesterly. This will push the front southward which could move through ArkLaTex Sunday. We could see a slightly higher chance of rain on Sunday, chances will remain low. Cold, dry air will move behind the front next week. Highs will eventually settle into the mid-90s. Overnight lows will fall into the lower 70s. Both are very close to normal for this time of year.

Probability of rainfall for 10 days: So far this August, Shreveport has received only a trace of precipitation, making it its driest August on record. The long-term model mix still shows that Shreveport and most of the ArkLaTex could stay completely dry through next week. If that happens, not only will this month be considered the driest, it will also tie or set a record for the most consecutive days without measurable rain. Remember, there is hope for some rain on Sunday, but if we do get some, it probably won’t be very heavy. So today’s forecast holds good and bad news. The good news is that some heat relief is on the way. The bad news is that we will likely stay dry.
