561 FXUS64 KHGX 061115 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 615 AM CDT Sun Apr 6 2025 ...New AVIATION... .SHORT TERM... (Today through Monday Night) Issued at 212 AM CDT Sun Apr 6 2025 Gusty NW winds and lingering showers with isolated storms continue over the I-10 corridor and extending down towards the coast. The Cold front is now well offshore, but lingering elevated moisture overlapping with PVA from an upper level trough currently located over the Texas panhandle allows for rain/storm chances to persist going into the late morning hours. The passage of the 850mb front scoots out the lingering moisture and brings an end to the rain chances for quite awhile! You might need a light jacket in addition to an umbrella as you head out the door this morning as temperatures will be starting out in the 40s/50s. With lingering cloud cover north of I-10 and CAA prevailing, we won`t see too much in the way of warming this afternoon as high temperatures are only expected to reach the upper 50s to low 60s. Surface high pressure moves in later today bringing in much drier air (PW values near or below the 10th percentile). Northwesterly winds will remain a bit elevated going into tonight as a 25-30 kt LLJ remains overhead. Low temperatures tonight will still bottom out in the upper 30s to low/mid 40s...but those upper 30s are a product of skies clearing out allowing for more efficient radiational cooling. With surface high pressure overhead, Monday will be dry and pleasant with high temperatures in the 60s and low temperatures back in the 30s/40s. It`s not necessarily important to the forecast, but a shortwave trough axis will be moving in going into late Monday. With dry air still in place, this won`t do much other than generate a few upper level clouds...so we might get a decent sunset photo opportunity in some areas tomorrow night! Batiste && .LONG TERM... (Tuesday through Saturday) Issued at 212 AM CDT Sun Apr 6 2025 Ridging aloft will prevail through most of the week, leading to relatively dry conditions. Southerly flow will resume after Tuesday as the surface high shifts to our east. As result, a gradual warming trend is anticipated with highs climbing into the mid 80s by Saturday. Overnight lows will generally remain in the 50s and low 60s. Despite onshore flow, moisture will remain limited; therefore, dry weather will prevail through the period. JM && .AVIATION... (12Z TAF Issuance) Issued at 615 AM CDT Sun Apr 6 2025 MVFR ceilings are areawide this morning as lingering scattered rain showers continue along the coast and east of the I-45 corridor. These showers will gradually decrease in coverage throughout the morning hours and push completely offshore by the late morning/early afternoon. The main challenge for today will be the timing of ceiling improvements. Southern sites will see an earlier improvement to VFR (before or around 21Z) whereas northern sites are expected to linger around high-end MVFR/low-end VFR through the afternoon. VFR conditions will return by the evening hours. Northwesterly winds will remain gusty throughout the day with sustained winds around 15-20 kt with gusts up to 20-30 kt...the higher end of both of those ranges will be closer to the coast. Winds decrease to around 10 kt overnight, but will pick back up into the 10-15 kt range on Monday. Batiste && .MARINE... Issued at 212 AM CDT Sun Apr 6 2025 Light showers with a few embedded thunderstorms can be expected through early Sunday as the cold front continues to move east of the Upper TX coast. The main marine concern is wind and seas. Strong offshore winds are already impacting the Bays and Gulf waters with near gale fore conditions at times. Moderate to strong north to northwest winds will continue today and tonight. Winds/seas will finally start to weaken/subside by Monday. Small Craft Advisories remain in effect through Monday morning. Light onshore wind resumes on Tuesday and will persist through the rest of the week. JM && .PRELIMINARY POINT TEMPS/POPS...
