The good news is that we don’t have a significant drying or warming trend over the next 7 days, the bad news is we will remain in the low 90s throughout the week, with the only hope for a cool down coming from the daily afternoon and evening pop up showers and thunderstorms.
For Saturday evening into Sunday morning, we will see a few isolates showers/t’storms over southern Arkansas. While this activity produced flash flood warnings last night, the rain tonight doesn’t look to have much staying power, so it should dissipate in the hours after sunset. Lows will be in the low 70s.
Sunday is shaping up to be another warm day with afternoon highs pushing into the low 90s. We may see the rain chances switch around from the northern ArkLaTex/I-30 corridor, to the southern half of the area south of I-20 in Texas and Louisiana. A better chance for sea-breeze driven rain will take shape late in the day.
Beyond the weekend, the ridge of high pressure will be overhead or just to our west throughout the week. This will keep the heat in place, but as the ridge slowly wobbles back and forth it will allow the daily 20 to 30% rain chances to continue. The best chances for rain appear to be late Tuesday through Thursday, and again we may see the best rain chances play out across the northern ArkLaTex (Oklahoma/Arkansas) throughout the week.
At least one model, the GFS, brings a tropical system along the Louisiana coast next weekend. Given many of the other models aren’t showing it, I have kept our rain chances low going into next weekend.
