.UPDATE... Issued at 606 AM CDT Sat Sep 6 2025
Adjusted PoPs through this evening weighing more of a solution that pushes the frontal boundary mostly through central Texas during the daytime. Rainfall overnight has primarily been in locations around San Antonio Bay with radar rainfall estimates near 1-1.5 inches over the last several 2-4 hrs. Just gives us a sense what these slow-moving storms can wring out.

.DISCUSSION... Issued at 1233 AM CDT Sat Sep 6 2025
Near normal temperatures will return this weekend into next week as cloud cover and rain chances increase. Very little changes from previous forecast packages. Increase moisture from the remnants of Lorena will continue to filter into the region ahead of an approaching boundary. What we do know is that rain chances will increase and all of South Texas should get some rain. What we still don`t know is just how much rain will fall and what areas will get the most. The forecast for rainfall amounts and location should come into better focus within the next 24 hours as Sunday and Sunday night (the expected most active periods) begin to enter the temporal resolution of the convective allowing models. The boundary is expected to be draped across the Hill Country Saturday morning and slowly move south before stalling somewhere across South or Deep South Texas. Where that front stalls will be key to what areas will see the most rain. A front stalling just north of South Texas will promote wetter conditions this weekend into early next week trapping moisture ahead of it while a stalling front further south over Deep South Texas would allow some drier air to filter in and provide a relief from the rain early next week. Therefore, kept high rain chances through Monday. Due to the the possibility of periods of heavy rain, the Weather Prediction Center has highlighted Sunday and Sunday night under a Marginal Risk of Flash Flooding (level 1 of 4) with a 5-14% chance of isolated flash flooding. Regardless of which solution plays out, a mid to upper level ridge is expected to

.AVIATION... (12Z TAFS) Issued at 606 AM CDT Sat Sep 6 2025
This morning, a lower cloud deck associated with showers and thunderstorms move onshore leading to borderline MVFR conditions.. PROB30 groups accounting for reduced VIS and CIG go through the late morning/early afternoon. Additional PROB30 groups for the afternoon convection have similar aviation reductions in flight categories. Tonight, convective storms diminish in the late evening. Sunday morning, most of the storms will develop wherever a sagging frontal boundary ends up, which may be closer to the coastline. Therefore a PROB30 group was added after 06Z to KCRP.

.MARINE... Issued at 1233 AM CDT Sat Sep 6 2025
A gentle to moderate breeze (BF 3-4) is expected this weekend through next week with a medium chance for a fresh breeze (BF 5) to develop Monday across the northern marine zones. Medium to high rain chances will enter the coastal water forecast today and persist through Monday, before dropping to low chances (less then 40%) Tuesday and Wednesday.
