993 FXUS64 KHGX 070458 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1158 PM CDT Fri Jun 6 2025 ...New LONG TERM, AVIATION, MARINE... .SHORT TERM... (This evening through Saturday Night) Issued at 110 PM CDT Fri Jun 6 2025 Mid-level ridge will continue to be the most dominant feature for the rest of today into Saturday. Although the ridge will limit our rain activity for much of Southeast TX, we could still see some isolated showers and possibly an isolated thunderstorm this afternoon, mainly along the coastal areas and for locations near the Galveston Bay region as we continue to heat up. Persistent onshore flow will continue to supply moisture from the Gulf and lead to Heat indices in the lower 100s this afternoon. Although these values are not yet within the Heat Advisory criteria, these temperatures can still lead to heat-related illnesses or injuries. Thus, continue to practice heat safety. If outdoors, stay hydrated, take plenty of breaks, limit the time spent outdoors, limit sun exposure, and wear appropriate clothing. Never leave children and pets unattended in vehicles. For tonight, we will start off with mostly clear to partly cloudy skies. As the night progresses, skies will become partly cloudy to cloudy. We may see some streamer showers during the overnight to early morning hours, mainly over the Gulf waters and the coastal locations, but accumulations will be minimal. Unfortunately, we wont have much relief from the warm and humid feels tonight, as low temperatures only dip into the mid to upper 70s for much of the area while dewpoints range a couple of degrees lower than the lows. Conditions heat up a little more on Saturday, with high temperatures in the mid to upper 90s for areas north of I-10, the lower to mid 90s for areas along and south of I-10, and the upper 80s to lower 90s along the coast. Heat indices are expected to range between 102- 106 deg F and can once again pose a heath risk for vulnerable populations as well as for those planning to spend long periods of time outdoors. The one good thing about Saturday is that we can anticipate somewhat breezy conditions as the pressure gradient tightens and a 25-30KT low level jet develops overhead. This will help a bit, however, make sure you are taking the necessary precautions during your time outdoors. Cotto && .LONG TERM... (Monday through next Friday) Issued at 1157 PM CDT Fri Jun 6 2025 Mid-upper ridging that brought us the hot conditions will gradually be suppressed to the s/sw as a larger trof dips further swd into the Midwest/Great Lakes/ MS Valley area early next week. Shower and tstm chances will gradually increase heading into the early and midweek time period due to the combination of prevailing moist onshore flow, less subsidence, daytime heating, and the ability for some intermittent upper disturbances and/or outflows from storms to our n/nw to make their way into the area. And with the increased cloud cover and rain chances should lead to temps lowering a bit closer to seasonable norms. During the mid and late work week, we should see another mid level trof take shape across West Texas and slowly track ene across the Southern Plains which should allow chances for daily showers/tstms to continue. 47 && .AVIATION... (06Z TAF Issuance) Issued at 1157 PM CDT Fri Jun 6 2025 Most locations are starting out with VFR conditions, though there are a few spots reporting 4-6sm vsbys in haze. Anticipate that we`ll see some MVFR cigs take shape across parts of the area later tonight into mid morning Saturday...with better chances more prevalent generally north of the metro area. Otherwise, look for VFR conditions along with some haze conditions during the day. Though a very short lived, an isolated shra or two can`t completely be ruled out, they`re not worth mentioning in the TAFs. 47 && .MARINE... Issued at 1157 PM CDT Fri Jun 6 2025 Fairly typical summer time pattern is anticipated for the next several days with a prevailing onshore flow. Speeds should typically be highest (14-17kt) at night in the Gulf and during the afternoon/evening in the bays. Seas will mostly be in the 3-5ft range. 47 && .PRELIMINARY POINT TEMPS/POPS...
