Marine Weather and Tide Forecast for Port Aransas, TX

DISCUSSION
Issued at 1208 PM CDT Fri Jun 13 2025

Will maintain a low (20-40%) chance of Pops across the forecast area for this afternoon given the weakness in the height fields aloft.
Moisture levels, PWs, were running around 1.8" with a weak onshore flow, high instability and a weak cap. WPC has highlighted the Victoria Crossroads area in a Marginal ERO for this afternoon, given all the rainfall in this area yesterday, but since there is no boundary to focus precipitation, we are not expecting flooding today. The shower activity should dissipate with the loss of heating this afternoon. Forecast soundings also show the cap increasing later this afternoon and evening. The weakness in the height fields persists through nearly the entire forecast period into the middle of next week. Thus we will keep low chances (20-40%) for PoPs in the forecast each day. An inverted trough could approach the area from the gulf Wed-Thu increasing our moisture and rain chances for late week. Subsidence ahead of this trough, could lower rain chances slightly on Tue.

Temperature wise, expect fairly seasonal temps with heat indices mostly in 105 to 109 range. Some locations could flirt with heat advisory criteria (110 or greater). But not confident enough to issue just yet.
