| Area Forecast Discussion National Weather Service Houston/Galveston TX 131pm CDT Tuesday September 30 2025 ...NewARINE... .KEY MESSAGES... Issued at 1106am CDT Tuesday September 30 2025 - Continue to use caution when working with open flame or equipment that can cause sparks and start a fire. Dry conditions persist. - Rain chances will be near zero through Thursday, but begin to rise late this week and into the weekend when moisture deepens enough to allow for some isolated seabreeze showers/storms along the coast. Issued at 1106am CDT Tuesday September 30 2025 Skies have rapidly cleared today from west to east giving way to a dry, seasonably warm day across SE Texas. These dry conditions will be the primary weather concern through Thursday as dry vegetation and the dry atmosphere will lead to enhance fire weather danger. Please use caution when working with open flames or any equipment that could cause a spark. More on this in the Fire Weather discussion below. By Friday, a more easterly wind will develop across the Gulf Coast into SE Texas as a strong surface high pressure moves down the Eastern Seaboard. This easterly fetch will help bring gradually increasing moisture to our area that will persist at least through early next week. This slight increase in moisture will lead to a chance of afternoon showers and storms along the sea breeze beginning Friday afternoon, and be possible each afternoon into early next week. Areas south of I-10 will have the best chance to see this afternoon shower and thunderstorm activity as the sea breeze will likely not be able to extend much further north than the I-10 corridor. Increased moisture across more of the area next week may help bring isolated activity further inland, however an upper level ridge centered over East Texas will likely be a limiting factor. Temperatures through Thursday will be unseasonably warm (about 5-8 degrees above normal) with afternoon high temperatures rising into the low to mid 90s across much of the area. And while it will be warm, it will still be feeling fairly pleasant per SE Texas standards thanks to the dry weather. Temperatures will be slightly cooler over the weekend into next week as the easterly flow gets established with highs in the upper 80s to low 90s, but the higher moisture will lead to slightly muggier conditions. Overnight lows will be in the upper 60s to mid 70s through next week. Marine Issued at 1106am CDT Tuesday September 30 2025 Light winds (driven by the land breeze/sea breeze circulation) and low seas will prevail through Thursday. A more predominate easterly wind will establish by Friday that will prevail through at least early next week. Small craft will likely need to exercise caution at times Friday into Saturday as the easterly winds increase to around 15-20kt with gusts to 25kt and seas increase to 4-6ft. Cannot out rule the need for a Small Craft Advisory Friday or Saturday if the higher wind gusts are expected to be frequent enough. There will be a chance of isolated to scattered showers and thunderstorms over the coastal waters beginning Friday through the start of next week. Fire Weather Issued at 1106am CDT Tuesday September 30 2025 No significant changes to the forecast from the previous discussion. There are a few Burn Bans in effect across the area: Madison, Colorado, and Wharton counties. Dry conditions will persist for the next several days. Daytime RH's are forecast to bottom out in the 28-35% range for a good part of the area through at least Thursday, and with drying fuels, this creates an environment more vulnerable to wildfire starts. Those doing land clearing will want to use some extra caution to ensure they are keeping any fire under control and have the resources to quickly respond if it gets out of hand. Those working with equipment (like loose chains, etc) - should be ensuring that sparks will be eliminated, minimized, or at least contained to non-flammable surfaces. Mitigating the dry fuel conditions will be light wind speeds that should be favorable to firefighting efforts in controlling any fires that may start, but it's probably really just better to avoid having the fires in the first place. A more easterly flow sets up heading into the weekend which should allow for a modest increase in dewpoints/RH's and low rain chances, primarily south of I-10 though. 47// NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None.
