9/27 – Rob’s “Continued WET” Morning Forecast

A moving frontal boundary will serve as the main features driving the forecast today. Conditions look favorable for an axis of repetitive showers and thunderstorms to develop along the frontal boundary this afternoon. The potential for some higher rainfall amounts will exist where heavier storms pass over the same area. Due to the extensive cloud cover and increased convective activity expected today, temperatures will remain near to slightly below average in the low to mid 80s.

Tomorrow will see the weak frontal boundary remain stalled along the Mississippi and Louisiana coast. It will continue to serve as a focus for scattered shower and thunderstorm activity. Saturday into Saturday night will see a deepening upper level low over Texas begin to force the weak frontal boundary along the coast back inland.

Monday through Wednesday will see a much drier and warmer weather pattern develop across the Gulf South. A strong upper level ridge will become centered over the region, and a resulting increase in subsidence will suppress convective development through the remainder of the extended period. The subsidence will dry out the mid-levels of the atmosphere. However, there should continue to be enough low level instability in place to overcome the mid-level capping inversion during peak heating hours in the afternoon, and have kept in a low end chance precip chances of around 30 percent through Wednesday to reflect this risk.

Thursday will see a deep pool of drier air advect in from the east, this deep pool of dry air will effectively kill any rain chances, and have a dry, sunny, and warm forecast in place. Temperatures should be well above average around 90 degrees Thursday afternoon.)
