Rain Tonight, Rain Tomorrow

Posted: Updated:

We've seen showers and thunderstorms throughout the day here in Cenla. Several different factors are helping this rain to develop. First, a high pressure ridge to our south has continued to break down, allowing for a stationary frontal boundary to sag into Central Louisiana. Warm, moist air from the Gulf of Mexico is riding up over this boundary allowing showers to develop. There is also a strong shortwave trough in the upper levels that has continued to approach us from the west throughout the day. This energy has combined with the stationary boundary and daytime heating to allow numerous showers and thunderstorms to continue to develop. As this upper level "vorticity max" moves into the area this evening we can expect a line of thunderstorms to move through Cenla, bringing heavy rains and strong winds at times. Some of these storms could be strong to severe.

The same is on tap for tomorrow as another shortwave is progged to move into the area. The stationary boundary will continue to hang around as well, allowing for continued thunderstorm development. By Thursday, this energy will move off to the east and a ridge of high pressure will slowly build back in. This will allow for less rain chances as we head towards the weekend. However, some models bring an inverted shortwave trough into the area by the later portion of the weekend, which could bring us increased rain chances again. It's still a little too early to tell at this point.

In the meantime, don't forget the umbrella.
