SHORT TERM (Today and Tonight)... Breezy afternoon winds have mixed some drier air aloft down to the surface as dewpoints have been trending lower through the afternoon. Despite winds remaining elevated, deeper low level moisture is expected to begin working into the region later tonight allowing both dewpoints and cloud cover to increase by early tomorrow morning.

LONG TERM (Sunday through Saturday)... An active weather pattern is expected for a majority of this forecast period with POPs slowly introducing itself Sunday morning then ramping up through the day. This activity will extend into the end of next week with rainfall totals around 1 to 3 inches expected... Southerly flow has already returned, enhancing moisture advection and priming the region ahead of the first frontal system set to reach our area tomorrow (Sunday). Storm Prediction Center D2 SWO has our CWA in a marginal risk for severe thunderstorms, with a slight risk clipping the northern fringe of our SETX Counties and CenLA Parishes. On D3, our CWA again is in a marginal risk. All modes of severe weather are possible, with hail and damaging wind gust being the prominent threats. Overall, though, the threat remains low with most of the severe weather expected for areas north of us. The front will slow then become quasi stationary over the gulf coast states by Tuesday. While this is a multi day event, most of the rainfall is expected Tuesday and Wednesday. The models project a bulk of the rain falling in our northern zones, around 1.5 to 2.5 inches, with 1.0 to 1.5 further south. Mid next week another frontal system will push east over the region. Thursday / Friday this front will help clear out the activity as a ridge of high pressure builds into the area behind it. The duration of this drier period is difficult to pinpoint with the models depicting different scenarios in the extended. Opted to load NBM POPs as a result.
