907 FXUS64 KHGX 011117 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 617 AM CDT Tue Jul 1 2025 ...New UPDATE, AVIATION... .KEY MESSAGES... Issued at 1209 AM CDT Tue Jul 1 2025 - The pattern of widespread afternoon showers and thunderstorms is over, but still could see an isolated afternoon shower or storm over the next few days. - Temperatures are on a warming trend with high temperatures expected to be in the mid to upper 90s by the end of the week. - Hazy skies persist as a layer of Saharan Dust moves over the region. - Got plans for July 4th? Make sure to stay hydrated and apply sunscreen if hanging out in the sun. Fowler && .UPDATE... Issued at 616 AM CDT Tue Jul 1 2025 Forecast remains on track, but nudged POPs up in the southern metro area later this afternoon. The last 10 runs of the HRRR have consistently shown a small cluster of storms pop up around the Houston Ship Channel/downtown area in the 2-5pm timeframe and probably worth the mention considering the population and possible impact to the late afternoon commute. 47 && .DISCUSSION... Issued at 1201 AM CDT Tue Jul 1 2025 The afternoon thunderstorms we experienced earlier had some oomph to them with rain rates approaching 2-4" per hour at times - but luckily they had enough movement to not cause any significant flooding concerns. There will be a slight chance of isolated showers or thunderstorms through at least midweek along and south of the I- 10 corridor, but coverage and intensity of these storms will much less compared to the past several days as high pressure builds overhead. However, this high pressure building overhead will also lead to rising temperatures through the remainder of the week. Temperatures are expected to peak Friday or Saturday with highs in the mid to upper 90s inland, and low to mid 90s along the coast. Expect continued hazy skies through this week as surges of Saharan Dust move through the region. If you have outdoor plans for July 4th, make sure to stay hydrated, take breaks in the shade or A/C, and apply sunscreen when outside. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 616 AM CDT Tue Jul 1 2025 Just some thin cirrus out there right now, but that has allowed for temps to cool to the dewpoint at several locations allowing for some patchy fog development. This should burn off a few hours after sunrise. Otherwise, VFR conditions should mostly prevail today...but terminals around the metro area should be on the lookout for some scattered pop-up tstms in the vicinity in the 20-23z timeframe as consistently indicated by the HRRR model. Precip should die off by early evening. SREF guidance indicates the potential for some more fog development along the I-10/US59 corridor later tonight...moreso just west of the I-45 terminals. 47 && .MARINE... Issued at 1201 AM CDT Tue Jul 1 2025 Light onshore winds between 5-10kt and low seas will persist through this week. An isolated shower or thunderstorm will be possible through midweek, but chances are much lower than compared to the past few days. Fowler && .PRELIMINARY POINT TEMPS/POPS...
