The day started out mostly cloudy and ended mostly cloudy. It was very hot throughout the late morning through the evening. No rain while I was at work in the Heights area of Houston, TX during the morning and early afternoon. It looked like it had wanted to rain when I was eating food with my friend at Willies near my house in Northwest Houston, TX during the late afternoon. I could see rain shafts and a rainbow traveling down 290 east on my way to the Petsmart in Katy after dropping off my friend in Cypress, TX during the early evening. There was a light drizzle and the roads were very slick as I was driving down I-10 west towards Katy, TX during the late evening. The roads were dry and there was not any more rain falling as I was driving home from Petsmart during the early night.

000 FXUS64 KHGX 292338 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 638 PM CDT Sat Aug 29 2020 .AVIATION [00Z TAF Issuance]... Some evening showers and thunderstorms in the area but not in the TAF sites. Most are in a broken line from the Hunters Creek area to the southwest around El Campo and continuing to move northeasterly and dissipate as the sunsets. After that, VFR conditions prevail until the early morning hours with some MVFR ceilings through mid morning. By 15z the lower stratus will scatter out with the heating and some fair weather cu will prevail through the day. Afternoon and evening showers and coastal thunderstorms are possible tomorrow as well. Most will be short lived and move out by sunset. 35 && .SHORT TERM [Tonight Through Sunday Night]... A few isolated showers and thunderstorms showing up on radar this afternoon, although coverage thus far has remained minimal. Despite this, sufficient instability (3000+ J/kg SBCAPE) and ample low-level moisture should prove favorable for the formation of some additional storms over the next couple of hours before activity diminishes upon the loss of daytime heating. Development should be limited to airmass thunderstorms given the lack of effective wind shear. Hot and humid conditions otherwise remain the main weather story through the remainder of the weekend. Look for similar conditions on Sunday to what has been observed thus far today, with onshore flow continuing to provide a steady supply of Gulf moisture to the area. This should keep heat index values in the hazardous range, potentially reaching as high as the low 110s as we`ve seen over the past couple of days. This may require another Heat Advisory tomorrow, although that decision will come with the overnight forecast package. Global models continue to indicate a stronger surge of moisture beginning tomorrow, with both the NAM & GFS solutions indicating a rise in PW values above 2.0 in across the southern half of the CWA with the greatest moisture availability around Galveston Bay. Have maintained PoPs in the 30-40% range with the highest numbers remaining in the southeastern portion of the area. Development is likely to mirror the activity of the past few days, with showers and storms developing offshore in the morning and pushing inland throughout the day. For those looking to enjoy some time on the beach this weekend, the risk for strong rip currents will continue given the persistent onshore flow. If you do enter the water, remember to only do so near a trained lifeguard and know the steps to take should you become caught in a rip current. Cady .LONG TERM [Monday Through Saturday]... Expect shortwave to travel south across the Rockies and carve out a trof across central parts of the country by midweek. Model solutions vary somewhat on its evolution beyond then...whether a part of the trof separates and travels under the western ridge, and/or weakens and travels north and east of the ridge stretching from the Atlantic across the northern Gulf Coast. Probably won`t impact wx all that much locally regardless considering lack of support for a continued southward push into the area with its associated frontal boundary. Better rain chances look to be to our north closer to the weakening front. Otherwise, typical late Aug wx anticipated across the area with iso/sct diurnally driven precip this week. 47 .MARINE... Look for a tightening pressure gradient has we head into the early- mid parts of next week. Expect southerly winds to increase and building seas as this occurs. May need some caution flags at times. Speeds should be highest at night in the Gulf and during the day in the bays. Winds/seas should then be on a downward trend during the second half of the work week as a weak front sags into Texas and becomes diffuse. 47 && .PRELIMINARY POINT TEMPS/POPS...
