Our weather will be returning to a more typical summer pattern for Thursday and Friday. That means highs in the low 90s, lows in the mid 70s, and a 40% chance of rain and storms in the afternoon hours. By late Friday a big trough of low pressure will move across the Rocky Mountains and that will weaken an area of high pressure to our north. This will allow an upper level disturbance to move our way on Saturday and that will combine with abundant moisture already in place. All of this means rain and thunderstorms look very likely on Saturday so if you have outdoor plans you may want to move them indoors!
We should return back to our typical summer pattern by Sunday with a slight reduction in the number of showers and storms through the middle of next week. So Sunday through Wednesday expect highs in the low 90s, lows in the mid 70s, and a 30% chance of afternoon showers and storms. If you have Labor Day plans the weather should cooperate for the most part, but there could be a few showers around.
The rest of the tropics are quite active too with Hurricane Cristobal expected to pass between Bermuda and the United States tonight and then move out over cooler waters and weaken quickly over the next few days. Elsewhere we are watching two tropical waves; the first is in the western Caribbean Sea but this will take a few days to develop if it develops at all. This could eventual reach the southern Gulf of Mexico by the weekend but it will likely stay well to our south.
The other area we are watching is near the coast of Africa where a strong tropical wave is about to move offshore and the environmental conditions look favorable for development over the next few days. However this system has two options; it could turn more northerly if it develops rapidly, or it could continue westerly if it remains disorganized for a while. The northern options would mean no threat to land, while the western options means it would have to be monitored for further development and possible interaction with land in a week to 10 days.
We will continue to watch the tropics closely and will keep you informed of any threats to Southwest Louisiana. But no need to worry about the tropics for now just the increased chance of rain for the weekend.
