(Today through Saturday night) Issued at 1223 AM CDT Thu Aug 28 2025 A few light showers have hung on late this evening near the coast supported by a weak quasistationary frontal boundary. While one or two showers can`t be completely ruled out through the early morning, expect this activity to remain minimal. However, convection will increase again by late morning with the boundary providing a focus for slightly above normal PoPs through the afternoon. The bigger weather issue in the short term will be a surge of deep moisture expected to push into the region Friday into Saturday ahead of another frontal boundary. Widespread showers and thunderstorms are expected to begin by late Friday morning and continue through Sunday evening. Coverage may be somewhat lower during the overnight hours Friday and Saturday, but storms are expected to continue through the night. The saturated moisture profile will yield efficient rainmakers capable of producing periods of torrential rainfall that could lead to nuisance street flooding. WPC has maintained a marginal risk for excessive rainfall across the entire region Friday through Sunday. The high rainfall and cloud cover will moderate afternoon highs which will peak in the mid to upper 80s over the weekend. Jones && .LONG TERM... (Sunday through Thursday) Issued at 1223 AM CDT Thu Aug 28 2025 A frontal boundary will push through the region Sunday with a somewhat drier and marginally cooler airmass advecting into the region Monday and Tuesday. Afternoon highs will peak in the upper 80s with overnight lows ranging from the mid 60s to 70 and dewpoints in the same range. It`s not quite fall, but it looks to be a noticeable and somewhat early relief from early September heat. Long range guidance shows the synoptic pattern of upper troffing remaining in place across the eastern conus through the end of next week possibly pushing another noticeable frontal boundary through the area toward the end of next week. Jones && .AVIATION... (06Z TAFS) Issued at 1146 PM CDT Wed Aug 27 2025 Mostly quiet / VFR night with exception to a few nocturnal showers along and south of the I-10 corridor. Some of these, especially near the lower Acadiana terminals, are heavy showers, leading to reduced VIS. Model guidance have isolated nocturnal showers along the coast through the night. Along with this, there still exist the possibility for patchy fog through the overnight hours. Tomorrow afternoon, we will see an uptick in showers and storms once again as a boundary continues to lift northward out of the Gulf. Some areas could see tapering in activity after sunset, however areas further north and closer to the boundary could see a continuation of activity throughout tomorrow night. && .MARINE... Issued at 1223 AM CDT Thu Aug 28 2025 Light onshore winds will prevail into early Saturday. A slowly advancing front slides south Friday into Saturday which should bring about widespread shower and thunderstorm activity. Winds will turn offshore late Saturday or Sunday through the middle of next week as the frontal boundary moves off the coast. && .FIRE WEATHER... Issued at 1223 AM CDT Thu Aug 28 2025 Scattered afternoon thunderstorms are expected Thursday enhanced somewhat by a weak boundary near the coast. Humidity will increase significantly Friday through Sunday as moisture surges ahead of another frontal boundary yielding widespread showers and thunderstorms through much of the weekend. The front will push through the area Sunday turning light winds out of the north Sunday through mid next week pulling some slightly drier air into the region Monday through Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
