.DISCUSSION... Issued at 1228 PM CDT Wed Sep 17 2025
Daily low to medium rain and thunderstorm chances (20-40%) continue through early next week in response to a few passing disturbances in the flow aloft combined with enough Gulf moisture and diurnal heating/instability. Most of the activity can be expected to occur along the sea breeze, and in the late morning to afternoon hours. By next week, however, some models are indicating a slight uptick in moisture over the area along with a somewhat stronger mid- level disturbance passage. This could lead to slightly higher rain chances, but have capped the NBM at 60% inland, until better agreement is reached. Otherwise, expect slightly above to above normal temperatures through next week, with highs in the 90s and overnight lows mostly in the 70s.
A persistent easterly flow over the coastal waters during the past few days has lead to tide levels reaching 1.6-1.7 ft at high tide in Port Aransas. This has resulted in water reaching some of the walkways and approach the dunes overnight, before receding by daybreak. No Coastal Flood Advisory is currently in effect, but conditions will need to be followed closely in case one is required overnight for the next high tide cycle (~ 4 AM).

.AVIATION... (18Z TAFS) Issued at 1228 PM CDT Wed Sep 17 2025
Mostly VFR conditions will prevail across area terminals through the cycle, with the exception of a brief period (08-12Z) of MVFR visibilities at VCT early Thursday owing to patchy fog formation. A few showers could impact the western sites this afternoon, but confidence on timing and location remains low. Therefore, have not added a mention of it in the TAFs, but will keep track of the current activity in case amendments are necessary. Winds will generally be light and variable, except at CRP where gusts to 20 knots are expected this afternoon.

.MARINE... Issued at 1228 PM CDT Wed Sep 17 2025
A gentle to moderate (BF 3-4) east to southeasterly breeze will persist through early next week. There will be a low to medium chance (30-60%) of showers and thunderstorms through the week into the weekend, with slightly higher chances next week (60-70%).
