The day was mostly cloudy with puffy cumulus clouds and very hot. There was a 30 percent chance of rain for the Houston, TX area but I did not see any through my travels in southwest Houston, TX, Missouri, TX, and Katy, TX during the late morning and early afternoon. I did not see any rain at my house in northwest Houston, TX either. The sky looked hazy during the late night at my house in northwest Houston, TX.

000 FXUS64 KHGX 302346 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 646 PM CDT Sun Aug 30 2020 .AVIATION [00Z TAF Issuance]... VFR conditions for the night with some morning MVFR ceilings in the CLL/UTS/CXO TAF sites. Tomorrow the day will stay VFR with some coastal showers starting early and slowly moving inland. As seabreeze becomes stronger the showers are expected to build into thunderstorms in the LBX/SGR/HOU/IAH areas. These should only last through the evening and dissipate as the sun sets and sea breeze diminishes. After that, VFR conditions should prevail through the night. 35 && .SHORT TERM [Through Monday Night]... Expect scattered showers and thunderstorms to continue to popup (and quickly fall apart) along the sea breeze through this evening. The showers and thunderstorms should get to between Houston and Conroe by the late afternoon before the loss of daytime heating ends the activity. An uptick of PWATs late tonight into Monday morning coming in from the Gulf will help start showers along the coast a bit earlier tomorrow - just before or around sunrise. The isolated to scattered showers tomorrow will also be able to spread across most of the area by the afternoon. These showers and associated cloud coverage may be able to provide some brief relief from the oppressive heat, which will again be on for tomorrow. Heat indicies this afternoon has climbed into the 105 to 110 degree range and continue to rise. Some spots along the coast have climbed even a couple of degrees higher. This heat will continue tomorrow, with the one caveat alluded to above. If the coverage of the showers and thunderstorms is large enough, then the heat indicies might be a few degrees cooler. Take this morning for example at Galveston: The heat index at 10am was 111 degrees, but a shower moved through the area and at 10:45am the heat index dropped down to 98 (though it has since bounced back to 111). If enough showers popup tomorrow, then we may get a reprieve from the heat. Nevertheless, the Heat Advisory for today has been extended through tomorrow evening due to not much of an overnight cool down and heat index values to still climb into dangerous levels tomorrow. Fowler .LONG TERM [Tuesday Through Sunday] and TROPICAL... A continued warm, but dry midweek period is expected. Surge of drier air, currently seen near the Yucatan on the GOES Total PW product, should advect northward into the region. Combination of this and breezier southerly winds should limit most seabreeze activity and drive the higher moisture and focus better rain chances north and northwest of our CWA. As the pressure gradient weakens and PW`s slowly increase, slight chances should gradually return Thurs-Fri. May need to keep an eye on any convection/outflows that develops to our north late in the week on a diffuse frontal boundary should any try to sneak into northern parts of the region. Wouldn`t anticipate the front itself to make it all the way here. In regards to the tropics: a tropical wave near the Windwards should continue moving west the next several days. NHC gives this system a good chance of developing into a depression in the next day or two. Majority of the medium range solutions take the "center" toward Central America and Mexico, though a wave axis along its northern periphery may emerge off the Yucatan and into the Bay of Campeche late in the week...and toward the Mexico`s east coast this weekend. Upper ridging situated across the northern Gulf Coast states should theoretically keep things to our south, and of note, few models show much if any organization. That said...we are heading toward peak season (and it is 2020 after all) so it`s always worth keeping an eye on things regardless. 47 .MARINE... A tightening pressure gradient will lead to increasing southerly winds and building seas tonight into midweek. Combination of SCEC/SCA`s will probably be required at times. Winds/seas should gradually diminish during the second half of the work week. Offshore waters may see an increase of precip chances heading into the weekend depending whether the northern extent of an easterly wave axis described above extends that far north. 47 && .PRELIMINARY POINT TEMPS/POPS...
