Area Forecast Discussion National Weather Service Houston/Galveston TX 543am CST Thu Jan 23 2025 Long Term (Saturday through Wednesday) Issued at 246am CST Thu Jan 23 2025 At the start of the weekend, surface high pressure will be off to our east leading to a steady increase in low-level moisture through the return of onshore flow. If we look a couple of km above the surface, we'll find a rather robust LLJ extending SW to NE across central/east TX up towards the Great Lakes region. This is feeding into surface low pressure well into Canada, but it will help by providing an initial source of lift for the increasing moisture. Moisture further increases towards the 90th percentile (~1.33") by Saturday night and extending into Sunday as a slow-moving frontal boundary pushes into Southeast Texas. The LLJ will still be there on Sunday albeit a bit weaker, but likely still suitable enough for some LLJ enhancement for shower/storm coverage. Locally heavy rainfall will be possible on Sunday with high rainfall rates in the strongest storms. WPC has already placed the majority of Southeast TX in a marginal risk (level 1 out of 4) for excessive rainfall on Sunday. The return of onshore flow also means a steady upward trend in temperatures...although there's a brief pause into early next week due to the FROPA on Sunday. In general, expect high temperatures in the 50s/60s and low temperatures in the 40s/50s through Monday. Tuesday and beyond we move into a more active weather pattern as an upper level low approaches from the southwestern CONUS around midweek and establishes southwesterly flow aloft. This will send rounds of shortwaves/PVA to interact with the in-place moisture giving us daily chances for showers/storms through most of the week. There is a frontal boundary towards the end of the forecast period that looks to surge low-level moisture and potentially giving us another round of heavy rainfall, but there is too much uncertainty on the exact timing of this. Just know that you'll need to keep an umbrella with you throughout the week. High temperatures will be mainly in the 60s Tuesday onward to pair with low temperatures mainly in the 50s. Batiste Marine Issued at 255am CST Thu Jan 23 2025 Light northeast flow tonight will become increasingly moderate during the daytime on Thursday following the passage of a dry cold front. This will result in caution flags for at least the farshore Gulf waters through Friday morning. Winds gradually transition to easterly on Friday then southeasterly by early Saturday morning. The onshore flow strengthens to moderate during the day on Saturday likely necessitating at least caution flags into Sunday. Seas increase in response and look to approach 6-7 feet Saturday night into Sunday. Chances for showers/storms return late Saturday, but will peak on Sunday afternoon/evening as a cold front pushes through leading to offshore flow prevailing into Monday.\ Batiste NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...Small Craft Should Exercise Caution from 9am CST this morning through Friday morning for GMZ370-375. |
