| Area Forecast Discussion National Weather Service Houston/Galveston TX 323am CDT Thu September 12 2024 ...New SHORT TERM, LONG TER Marine .SHORT TERM... (Today through Friday Night) Issued at 318am CDT Thu September 12 2024 Francine will push northward through the Mississippi River Valley today. Despite the storm's departure from our region, wrap around ML / LL moisture is pushing LL cloud coverage southward into our CWA (County Warning Area) this morning. These clouds are expected to break as the day progresses. Meanwhile, the mid/upper levels over Texas will continue to be dominated by the trough that helped push Francine to our east. The deep northwest flow combined with the clouds earlier in the day and relatively low mid/upper pressure heigheights will help keep temperatures in check, with highs mostly in the 85-90 degree range. Overnight lows will generally be in the upper 60s north of I-10 (low/mid 60s far north CWA), low 70s south of I-10 (and within Houston's urban heat inland), and mid 70s at the coast. Unfortunately for those who are looking for a cooling trend, the synoptic pattern will shift to ridging regime over south-central CONUS starting on Friday. RAP 500MB analysis already shows this ridge beginning to build over New Mexico and West Texas. This ridge will drift eastward, park its axis over Texas, and begin to amplify on Friday. Therefore, it is no surprise that Friday's forecast temps are a little hotter with most inland locations reaching the low/mid 90s. We do live in SE Texas y'all. It's hard to shake off summery weather in our neck of the woods. We'll feel the cooler winds of fall eventually. Just not anytime soon. Self Long Term (Saturday through Wednesday) Issued at 318am CDT Thu September 12 2024 A warming trend along with increasing humidity is expected through the long term period. Ridging aloft and surface high pressure to our east will dominate the weather pattern through most of the period. Strong subsidence and low PWATs (Precipitable Waters) (~1.2 to 1.5 inch range per NAM) will result in little to no precipitation, though a few showers cannot be ruled out near the coast. Increasing heigheights and onshore surface winds will bring back above normal temperatures. In fact, the NAEFS standardized anomaly table maintains 1 to 2 standard deviations above normal for 850 mb temperatures Saturday through early next week. This will add confidence that surface temperatures will range a few degrees above normal for this time of year. Have highs into the mid to upper 90s Saturday through Monday, with the warmest values generally across the Brazos Valley. Mid to upper level heigheights weakens a bit next week in response to the amplification of a trough moving across the Pacific Northwest. Weaker heigheights will lead to an increase in low- level moisture across our region through the week. Overall, expect hot and humid conditions with isolated showers or storms, mainly over the coastal zones. JM Marine Issued at 318am CDT Thu September 12 2024 Weather conditions will continue to improve today with light to occasionally moderate north to northeast winds and low seas. Surface high pressure will move over the region, resulting in benign weather into the upcoming week. Onshore winds return by Friday as the high pressure shifts to our east. A few showers will be possible every day, especially near the coastal waters from Freeport to Matagorda Ship Channel. However, impacts should be very minimal. Beach conditions: Conditions are improving, but there is still a risk of minor coastal flooding and a high risk of rip currents through this afternoon. JM NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...Coastal Flood Advisory until 7pm CDT this evening for TXZ214- 313-335>338-436>439. High Rip Current Risk through this evening for TXZ436>439. GM...None. |
