Dry conditions expected through Friday then the return flow will begin to bring the humidity and warmth back to the area.
Saturday through Tuesday: a relatively strong late season cold front moves out of Canada Friday but quickly shunts eastward to bring an elongated frontal boundary into the western Gulf States region Saturday. This should allow for decent rain chances with frontal convergence interacting with gulf breeze that may induce fringe cold air advection off the coast by Saturday evening.
Frontal zone becomes diffuse to weak warm front in nature by Sunday to allow for spotty t-storms as it pulls north in advance of next Plains system. Models are showing slow evolution of that system into middle of next week, thereby leaving the gulf coast region under the influence of moderate onshore flow.
Temperatures should start off near normal Saturday but trend abnormally warm and humid into next week.
