Currently, CenLa is sort of sandwiched between an upper level ridge of high pressure in the center of the US, and a wave of tropical moisture in the gulf, which puts us in a difficult position while forecasting. While most of SE Louisiana is expected to be wet tomorrow, the vicinity of the high pressure is bringing drier air from the north and suppressing thunderstorm activity. As the moisture moves toward the west, the dry air may inhibit development of this moisture. It really depends on how much this area of high pressure influences the region. The southern portions of our viewing area may see rain while the N and NW areas may not. I believe if a choice had to be made, that the high pressure will likely influence our weather pattern slightly more than the moisture from the gulf, so I'm calling for a 40% of thunderstorm coverage tomorrow. More about this moisture from the gulf can be found on our hurricane blog located here.
SATURDAY NIGHT...Partly cloudy with a slight chance (around 20%) of rain. Temperatures will reach the lower 70s with some patchy fog possible.
SUNDAY...Patchy fog is possible early followed by partly cloudy to mostly cloudy with a 40% chance of showers and thunderstorms. Highs near 93. The peak heat index may reach 104. SE
