National Weather Service Shreveport LA 701 AM CDT Sat Apr 20 2024 ...New AVIATION... .SHORT TERM... (Saturday through Sunday) Issued at 335 AM CDT Sat Apr 20 2024 Very diffuse frontal boundary has cleared our southernmost zones this morning with spotty post-frontal showers starting to expand across parts of East Texas and North Louisiana. This trend will continue to ramp up over the next 24 hours in terms of convective coverage and intensity as a series of upstream shortwave impulses translate eastward across Texas into the Lower MS Valley. Although convection will gradually overspread the entire region later today and tonight, pockets of heavy rainfall and embedded thunderstorms are expected to become more focused along and south of the I-30 corridor where 1-2 inches of rainfall will be common along with localized higher amounts near 3+ inches. The bulk of this rainfall should occur from this afternoon through early Sunday morning before the primary trough axis finally pivots overhead and gradually brings an end to the rainfall. Cloud cover will eventually follow suit by Sunday afternoon with at least some sunshine returning late in the day. As a result, afternoon warming will allow high temperatures to climb into the 60s areawide versus slightly milder rain-cooled air across the majority of the region today. The exception will be across our far southern zones closer to the frontal boundary where cool air advection hasn't been quite as pronounced given how diffuse the front has become. Regardless, we will maintain below average temperatures areawide with morning lows bottoming out in the 40s near 50 degrees across the region. /19/
