5/18 – Rob Martin’s “Eventually Storms Return” Wednesday Night Forecast
It’s more of the same at least into Thursday as high pressure in the gulf remains in control. The northwestern periphery of the high will start to break down by Friday, especially in the mid and upper levels. However, some slightly drier (although still humid) air over the western Gulf of Mexico will get pushed around the periphery of the high tonight into Thursday. This slight decrease in moisture, along with increased sinking air, should be enough to inhibit deeper updrafts from developing, thus capping any thunderstorm development. Showers or thunderstorms are unlikely Thursday due to proximity of the high, with a 20% chance of morning showers on Friday as the high gives some ground. Highs each day range from the upper 80s along the coast to lower 90s inland. Overnight temps will remain elevated in the mid 70s, a good 8-10 degrees warmer than average for the season.
