.DISCUSSION... Issued at 1255 PM CDT Sun Sep 7 2025
Scattered showers and thunderstorms, some locally heavy, this afternoon should wane in coverage this evening as drier air behind a frontal boundary filters into SE Texas. However, the front is expected to stall offshore, keeping a chance of isolated to scattered showers / thunderstorms in the forecast into the overnight for areas near the coast. As we head into Monday and Tuesday, expect generally dry conditions with much lower humidity. The forecast has trended a little cooler, with Monday/Tuesday highs ranging from the mid 80s in our northern counties to upper 80s to around 90 in our southern counties. Based off the trends, I`m now thinking that even areas within the urban heat island have a shot of dropping into the 60s (likely upper 60s) on Monday night and Tuesday night. Rural areas away from the coast likely fall into the low to mid 60s. The coolest northern Piney Woods spots could fall into the mid/upper 50s! The heat starts to build again thanks to a building ridge overhead later in the week, with highs expected to be in the low/mid 90s by week`s end. Humidity is expected to be on the rise as well. But it isn`t forecast to be THAT bad for SE Texas standards.
Despite the mostly dry forecast, the presence of the stalled frontal boundary offshore will keep a slight chance of showers and an isolated thunderstorm in the forecast for areas near the coast and especially offshore through much of the week.

.MARINE... Issued at 1255 PM CDT Sun Sep 7 2025
A frontal boundary moving into the area now will stall offshore, keeping a chance of showers and storms over the Gulf waters through much of this week. A steepening gradient between the front and a passing surface high to the north will enhance northeast flow, especially on Monday when winds and seas may warrant caution flags (winds 15-20 knots w/ higher gusts, seas 3-5 feet). For most of the rest of the week, winds are expected to average out of the east near 10-15 knots. But occasionally higher winds will be possible. Locally higher winds and seas will be possible in the vicinity of any thunderstorm.
