Summary: The day was warm, sunny, and mostly cloudy. Maybe some rain. I think I felt a few drops. I also saw a few small light showers on the TWC, Houston, TX radar. The wind speeds were calm with moderate to moderately strong gusts and some really strong 20 to maybe 25 mph gusts. There were no watches, warnings, advisories, or weather statements issued for the Houston, TX area, during anytime of the day, that I know of. The low temps were in the 60's and the high temps were in the 70's and 80's, for the Houston, TX area.
Location: Northwest Houston, TX.
Thoughts: I'm getting ready for another stormy day tomorrow.

000 FXUS64 KHGX 020126 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 826 PM CDT Sat Apr 1 2017 .AVIATION... Long and messy TAFs. Updated just a few minutes ago to add VCSH across the board given the rapid development of SHRA across the area. One thunderstorm has already formed near PSX as 0035z. Guidance appears to be underforecasting the ongoing precipitation over SETX at least in the short term. As LLJ strengthens will probably see more hit or miss showers develop and race NNW. Winds have backed to the east and southeast as expected (which has helped to feed moisture westward into the Hill country and limit it`s northward advance through SETX) and will continue throughout the night with CIGS lowering and widespread MVFR decks to prevail. Showers and thunderstorms should pickup in coverage dramatically Sunday morning after 12z with impacts to the Metro area terminals 15-23z. Storms will be moving faster as the day wears on and may begin at 20 knots and by noon storms maybe moving at 35+ knots. At some point expect a more solid line to take shape in close proximity to the warm front near CLL-UTS- DKR with longer duration impacts for those areas. Dry slotting works into the area late afternoon but may see a few storms develop along the Pacific cold front as it marches through the region in the out period and beyond. 45 && .PREV DISCUSSION... /ISSUED 401 PM CDT Sat Apr 1 2017/ DISCUSSION... FLASH FLOOD WATCH IS IN EFFECT FROM LATE TONIGHT THROUGH SUNDAY EVENING... All of the elements required for active Sunday weather are forecast to synchronize over southeastern Texas during the daytime hours. High moisture flux into a developing warm front within a highly sheared environment all suggest that tomorrow will be a severe weather day. Other than a quick passing shortwave around the upper low throwing off the timing of onset...expect the most intense weather to occur mainly from around sunrise through (at the latest) early Sunday evening. The focus for the highest rainfall will be across the northern tier counties...or in the vicinity of the best low to mid level convergence provided by the northern-advancing warm frontal boundary. SPC has placed the region under a (fairly infrequent) Moderate Risk. There is also a Flash Flood Watch in effect across the far northern zones. Surface low pressure over the lower Rio Grande Valley will lift up and over central Texas tomorrow as the upper low over northern Mexico advances into extreme southwestern Texas. This will aid in drawing up a lower 70 F (sfc) dew point air mass. The warm front leading this moisture rich air will provide the needed lower level convergence for early day showers and isolated storms to fire. The atmosphere is turning in the lower levels and creating helicity indices supportive of rotating updrafts leading to tornadic super- cellular behavior. Winds veer more efficiently in the lower few km earlier in the day. Thus...the tornado threat from discrete cells leading a more organized central Texas line of convection will be highest earlier in the day...especially over the central and southern counties. As cells move across the warm front...lower level vorticity could become more enhanced. A strengthened lower level jet will provide better mid-level exhaust to maintain early day discrete cellular evolution. Pwat air of greater than 1.5 inches (possibly 1.7-1.8 inch pwats that would be above the 99th climate percentile) being pumped in at a greater than 60 degree angle should be ample fuel to maintain interior thunderstorm activity. In essence...when completing the flash flood decision tree...you get all high scores in relation to a classic warm air advection pattern set-up. A Flash Flood Watch will be in effect from 4 AM through 7 PM Sunday for the far interior northern counties as well are forecasting the highest rainfall from roughly north of a Caldwell to Huntsville to Groveton line. Lower wet bulb heights signal a hail threat with high column winds (shear) and weak PM inverted V`s lending themselves to a high (storm) wind threat. A better stacked lower to upper level low over northeastern Texas late Sunday night will aid in weakening the system over state late Sunday... a dry slot moving in from the west scouring out areal precipitation late Sunday night into early Monday morning. Other than a mid week (primarily dry) cold frontal passage...this coming work week`s weather is forecast to be tame. After a wet and overcast Sunday in the mean middle to upper 70s...60 F minTs with average middle 80 maxTs early in the work week will `cool` into the post frontal low/mid 50s for mins and mid/upper 70s from mid week through Friday. 31 MARINE... A moderate to occasionally strong onshore flow will persist tonight as low pressure over West Texas deepens. Will maintain the SCA for the Gulf waters but not sure that it is needed over the near shore waters as winds/seas slightly lower. An upper level disturbance will bring a good chance of showers and thunderstorms to the coastal waters on Sunday. Mariners should remain alert for rapidly changing conds on the water and prepare for strong storms Sunday aftn with damaging winds possible. The low will push NE Sunday night and Monday with a weak offshore flow developing on Monday. Winds will quickly back to the south Monday night and remain onshore through early Wednesday. Another cold front is progged to move across the coastal waters late on Wednesday morning. A strong offshore will develop in the wake of the front on Wednesday afternoon through early Thursday. Weak high pressure over the central plains will ridge into Texas on Friday bringing light and variable winds. A light onshore flow will develop Friday night as the surface high shifts east. The onshore flow will strengthen next weekend as the high shifts further east and low pressure over the central plains deepens. 43 && .PRELIMINARY POINT TEMPS/POPS...

The severe weather threat encompasses the whole region for the potential of tornadoes, hail and damaging winds. Locally heavy rainfall may also occur and lead to flash flooding in low lying areas as well as rapid rises on area rivers, creeks and bayous. There is still some uncertainty on the timing of these threats but generally think the potential will begin after midnight Sunday and persist through much of the day. .SPOTTER INFORMATION STATEMENT... Spotters will need to have a heightened awareness on Sunday. $$
