5/10 – Rob’s “Midday News” More Humid Forecast
HOT & HUMID will continue as light onshore flow on the western side of the high-pressure centered over the northeast Gulf of Mexico will remain in place. Strong subsidence aloft today and tomorrow will keep dry weather and mostly sunny skies in place. By Saturday, the ridge axis should begin to break down as a broad upper level trough of low pressure moves into the central and eastern Gulf of Mexico. An increase in mid-level moisture is expected as this trough gradually approaches from the south, and scattered afternoon showers and thunderstorms will be possible Saturday afternoon…mainly in SE Louisiana.
By Tuesday, a transition in the pattern is expected with ample tropical moisture feeding in from the south, scattered showers and thunderstorms should develop in the afternoon hours. The convection will once again be driven by daytime heating as temperatures climb into the lower 90s and instability values peak.
