Today: High pressure has lost its influence which will allow for more rain. Showers and thunderstorms will be more in coverage between 80 to 60% with rain chances mostly in the afternoon. The humidity will also be back to higher levels with highs in the mid-80s and partly cloudy skies otherwise. The higher humidity will lead to heat index values between 90 and 95 degrees if the rain gets a late start. Overnight lows will be in the low-70s.
Tomorrow: It will be very similar to Tuesday. More rain and similar temperatures and humidity.
Thursday: Thursday likely won’t be as wet as Tuesday and Wednesday but still, a 50 to 60% coverage of showers and thunderstorms is likely thanks to ample moisture still in the region. Highs will remain in the mid-80s.
Friday-Sunday: A front fails to fully make it to Louisiana, but drier air still moves in with high pressure settling in. This will lead to isolated rain chances with temperatures in the mid-to-upper 80s and partly cloudy skies.
Tracking the Tropics: Hurricane Sam is a major hurricane that will move north into the Atlantic, away from Louisiana.
2 more tropical waves off the West African coast have a high chance of development over the next 2 days. We will have to watch these closely as they trek west-northwestward towards the Caribbean Sea and middle Atlantic.
One other tropical wave in the Atlantic is not a concern to Baton Rouge.
