Most are going to need their sunglasses over their rain gear this afternoon and on Thursday. However, our rain chances continue to increase late this week and, especially, this weekend. Only isolated downpours are expected this afternoon and Thursday. Scattered showers and storms will develop late Friday, which could impact some Friday night football games, and widely scattered to numerous showers and storms will be possible this weekend.
Rain is not expected the rest of tonight. We will just be left with a few clouds. Overall, it’s going to be warm and muggy. Lows will be in the low to mid 70s. There will be no need for a light jacket first thing Thursday morning.
Thursday will be our last hot and humid day before we start to see some changes. Highs on Thursday will be in the mid 90s. Keep in mind, the humidity will add a few degrees to the actual air temperature. Max heat indices will be near or just above 100 degrees. Once again, a isolated downpours will develop in the heat of the day. These showers and storms will driven by the heat, so they will quickly diminish Thursday evening.
The upper-level ridge that has kept us hot and humid so far this week will start to move east of the ArkLaTex on Friday. This will allow a cold front to drop far enough south to help increase our rain chances. Scattered showers and storms will be possible on Friday, especially late in the day and north of I-30. Highs on Friday will be in the low 90s.
Our rain chances will continue to increase this weekend. Scattered to numerous showers and storms will be possible on Saturday. Sunday won't be quite as wet, but a few more showers and storms will be possible, mainly south of I-20. Because of the clouds and rain, temperatures will be much more seasonable for this time of year. Highs will be in the mid to upper 80s.
Scattered showers and storms will possible through the middle of next week. Highs on Monday and Tuesday will be in the mid to upper 80s. Some of the forecast models are hinting a strong cold front could blast through the ArkLaTex towards the middle or end of next week. This front could bring in more showers and storms and our first taste of fall. Highs temperatures late next week might only be in the 70s and lows will be in the low 60s. This is something we'll continue to watch closely.
Stay cool and have a good night.
