Today: Today we still have influence from high pressure, but it is slowly moving out of the region today. This will lead to highs around 87 degrees today with mostly dry conditions, but a few showers are possible around sunset today. Humidity will be higher than the weekend but not too high. Heat index values should stay in the low-90s. Overnight lows will drop to around 70 due to increased cloud cover and possible late rain.
Tuesday-Thursday: Showers will be more in coverage between 70 to 50% with rain chances most of the day, each day. The humidity will also be back to higher levels with highs in the mid-80s and partly cloudy skies otherwise.
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-80s.
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 5 days. We will have to watch these closely as the trek westward towards the Caribbean Sea.
One other tropical wave in the Atlantic is not a concern to Baton Rouge.
