Today: The ridge of high pressure that has been keeping us hot and dry is beginning to move away from our region. Right now it is to our northwest and will move to our northeast in a few days. This combined with a low-pressure system over the Bahamas is leading to an overall atmospheric flow from the east. This will bring in more moisture into our region. Rain chances are back on the scattered to numerous spectrum, so expect a wet afternoon today with heavy downpours and isolated flooding issues remaining a concern with some of the storms. The actual temperature today could reach 93 today in Baton Rouge. Tonight will be partly cloudy with a lingering shower or storm possible. Overnight lows near 75 degrees.
Thursday-Saturday: Highs will be around 90 degrees each day with scattered to numerous showers continuing. Overnight lows in the mid-70s.
Sunday-Monday: The same pattern with highs around 90 and scattered showers and thunderstorms is expected to stick. However, this can change based on what happens in the tropics with a possible tropical storm or hurricane making landfall on the gulf coast somewhere on Monday morning. It is still too early to call.
Tracking the Tropics: Eyes are on the Caribbean where there is a high chance of development of a system in the next 5 days over the western Caribbean or the southern Gulf of Mexico. Development continues to look favorable as it approaches the Gulf Coast. We’ll have to monitor this one closely. Most global weather models currently project a hurricane making landfall near Lake Charles on Monday morning.
Two other disturbances in the Atlantic have a chance of development but are not a threat to Louisiana.
