Not much has changed over the past few days with temperatures reaching 90 then storms firing up in the afternoon. Near 90 degrees has been what we call the convective temperature, the temperature the earth must warm to in order for storms to develop with the lack of a front or lifting mechanism. Once that temperature has been reached the air is free to rise and condense into the clouds which later form storms.
Some areas had some pretty heavy rain today as storms trained over the same place. There was a flood advisory issued for St. Martin and Iberia parishes today. Rainfall estimates from radar indicate that some received up to 4 inches of rain. From just northwest of Loreauville to southern St. Martin parish there was a swath of 4 inches with another area from between New Iberia and Jeanerette that also had that amount. Elsewhere, most of us racked up on 0.5 to over 3 inches in the rain bucket. Lafayette recorded 1.42 at the airport.
Seabreeze storms will continue through the weekend and into next week with seasonable temperatures. I’m now able to get a peek at the preliminary July 4th forecast and it looks like a chance of rain in the afternoon then tapering off in the evening as we have experienced everyday lately. The tropics are still quiet with nothing expected to develop in the next couple of days.
