BATON ROUGE, La. (WAFB) - Relatively normal summer weather is anticipated Monday and Tuesday. Temperatures will climb into the low to mid 90°s with feels like temperatures reaching the low triple digits.

Jeff Morrow and the WAFB First Alert Weather team provide an update on What're We're Tracking Next on Monday, Aug. 8.

By mid-afternoon, scattered to numerous showers and t-storms will pop up. Rain amounts on both days should be manageable with most picking up between 0.25-0.50″.

An easterly wave (weak tropical wave) will be moving west across the Gulf of Mexico beginning Wednesday. Rain chances will increase into the likely category Wednesday through Friday. Rain could also fall outside of the typical afternoon timeframe during these days. Moisture levels will increase as the wave moves closer (Wed. PM - Thur. PM). The Weather Prediction Center has already issued a Marginal Risk (1 out of 4) for flash flooding Wednesday into early Thursday. It’s likely we will see another risk for flash flooding on Thursday as we get closer. Localized bullseyes of 2-4″ will be possible on both days which could lead to flash flooding of low lying, poorly drained areas. The majority of flood concerns will be nuisance type (roads, ditches, bayous, and streams). The easterly wave will begin to exit on Friday helping to reduce the heavy rain threat heading into the weekend.

Drier air in the mid levels will approach the area over the weekend as an East Coast trough deepens. This will help reduce rain chances back to the scattered category for Saturday and Sunday. Therefore, don’t cancel any outdoor plans you may have this weekend. Temperatures will increase back into the low 90°s, but for now, we’re keeping them below normal into next week. Rain chances may increase some towards the end of our 10-day forecast.

In the tropics, we continue to keep an eye on a tropical wave moving off the coast of Africa. We are still several days from any potential threat to the U.S. So we have plenty of time to monitor how things develop.
