8/15 – Trey Tonnessen’s “Radar View” Thursday Night Forecast

Meteorologist Trey Tonnessen

Showers and thunderstorms across the state line into Louisiana continue Thursday night as we begin our 9:00 PM newscast. Cold pool driven convection continues to dive southward across southeast Louisiana. The main effects have been wind gusts to about 40 mph, and very heavy rain. Several areas have received upwards of 2 to 3 inches of rain in an hour. Convection has weakened somewhat with the loss of daytime heating, but it will likely still take another couple hours for storms to shift westward into southwest Louisiana and/or southward into the coastal waters. The help of the weak boundary across the area, will aid in storm development to our west again tomorrow. Much of the convection will again be dictated by outflow boundaries as well as sea and lake-breeze boundaries.
