Northwest Houston, TX, during the early evening.
Summary: The day was warm, wet, and mostly cloudy. A slow moving stationary front brought heavy rain to the Houston, TX area, during the early morning and then some isolated to scattered light to moderate showers, during the mid and late morning, afternoon, and evening. Heavy thunderstorms passed over my house in northwest Houston, TX, during the early morning. I saw some on and off light to moderate rain and drizzle, during the late and maybe mid-morning and during the afternoon, and maybe early evening. Stratus, stratocumulus, and some occasional nimbus clouds looked to cover the whole sky, during the morning and then most of the sky, during the afternoon and evening. The wind speeds looked to be calm with maybe some gentle to moderate gusts. It felt warm, during the morning, afternoon, evening, and night. There were numerous flood watches, warnings, and advisories issued, along with a Special Weather Statement. There was also a Hazardous Weather Outlook issued for the Houston, TX area, by NOAA. The low temps looked to be in the 70's and the high temps looked to be in the 80's, for the Houston, TX area.
Storm Summary: There were reports of flooding on roads and highways with cars and trucks getting stuck and stalling out. I also heard of a downed tree. So there looks to have been some storm damage as well.
My Storm Summary: Lots of heavy rain with loud thunder and bright lightning, maybe some cloud-to-ground. I am pretty sure there was a lightning strike right next to my house. I heard the thunder right as the lighting was striking, instead of a few seconds later, like I usually do. I witness some flash flooding on the roads that I take to work in northwest Houston, TX, during the early morning and early evening. There still looked to be some flooding on the roads on my way home in northwest Houston, TX, during the early evening. I didn't see any storm damage, but I heard of a downed tree, from a co-worker, who said there was a downed tree in her neighborhood.
Locations: Northwest Houston, TX.
Thoughts: Well I guess I should have guessed that there would be flooding when I heard that their was going to be stalled front,or maybe low passing through Houston, TX yesterday and today. I just didn't really think about it.

000 FXUS64 KHGX 090202 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 902 PM CDT Tue Aug 8 2017 .DISCUSSION... For the evening update, we have added Galveston County (mainly for the Bolivar Peninsula area where some heavy rainfall fell late this afternoon through early this evening) to the Flash Flood Watch. There is some potential for additional shower and thunderstorm development overnight closer to the center of the slow moving low that we have been dealing with for the last couple of days. Hard to pinpoint exactly where the heaviest rains might fall, but best potential looks to maybe be setting up between the Houston and Beaumont areas where WPC upgraded their slight risk to a moderate risk in their Day 1 Excessive Rainfall Outlook. Any heavy rains falling on already saturated grounds will quickly lead to flash flooding. 42 && .PREV DISCUSSION... /ISSUED 717 PM CDT Tue Aug 8 2017/ AVIATION... Widespread scattered showers and thunderstorms are continuing to spiral around the area of low pressure currently centered just east of IAH. Expecting most precip to diminish for a short period of time this evening around 23-01Z, resulting in a lull in showers and thunderstorms until the late evening hours. Short term guidance such as the HRRR and ARW indicate redevelopment for the northern TAF sites around 02Z, shifting a line of convection southeastward through the IAH/HOU/SGR region by 09Z. Additionally, a second band of showers and thunderstorms pinned along the coast also redevelops around 07Z and pushes northward impacting LBX and GLS through the afternoon. Although there will definitely be the potential for scattered showers and thunderstorms circulating around the area of low pressure overnight, there is less confidence in how this low propagates. If the center of the low moves further eastward, we could see a shift in the rainfall more to the east, resulting in less impacts to all TAFs sites. Short term guidance has appeared to be sliding the precip further east in the most recent runs and forecasting the center to move eastward, so will have to continue to monitor to see if this trend continues. Otherwise, VFR conditions through late evening, with a MVFR deck expected to develop around midnight and hold through early morning. Overnight, winds will vary in direction around the center of the low, but should remain less than 5 kts inland and between 5-10 kts along the coast. Hathaway PREV DISCUSSION... /ISSUED 319 PM CDT Tue Aug 8 2017/ DISCUSSION... The main item of concern for this evening through Wednesday morning is the possibility of heavy rainfall mainly over the eastern areas. To that end, have continued the flash flood watch for Harris, Chambers, Liberty, Montgomery, Polk and San Jacinto counties through 8:00 AM Wednesday. A consensus of the models are fitting the location of the MCV (mesoscale convective vortex) which was near San Jacinto County at 2:30 PM. Because the area of the heavier rainfall looks to occur mainly from Chambers County northward, have dropped the watch for Waller and Fort Bend counties. From an overall perspective, a weakness in the upper level high pressure ridge will likely cause the MCV to meander a bit. Most models show the feature drifting southeastward and turning northward tonight. If the MCV shears apart, another MCV could develop if another mesco-scale convective complex forms tonight. With all the uncertainty, confidence in the model solutions are moderate at best. WPC 50th percentile showed heaviest rainfall possible across and east of Chambers, far eastern Harris and Liberty counties. Higher resolution models then have potential into San Jacinto and Polk counties. Best chances for showers and thunderstorms will be over the eastern and coastal counties on Wednesday. For Thursday scattered coverage of showers and thunderstorms is expected. As the upper level ridge builds overhead from the west, only slight chances are expected Friday through the weekend and into early next week. The building ridge will lead to less cloud coverage and increasing daytime temperatures into the mid 90s over the inland locations. Moisture from the Gulf could also increase and lead to an increase in the heat index to between 105 and 107 over the weekend. MARINE... Scattered showers and thunderstorms are possible once again tonight given the proximity of the upper level disturbance over SE TX. Best rain chances will be over the bays and nearshore waters. Otherwise, winds will remain light and from the SW overnight. Winds are expect- ed to become more SE and slowly strengthen by late tomorrow evening as this system moves out of the area. This increasingly moderate on- shore flow will be coupled with the possibility of increased swells from Franklin as it moves into the Bay of Campeche. Seas could range from 4-6 feet by Weds night through Thurs before gradually tapering off by this weekend. Rain chances should also be decreasing through the rest of the week with progs of an upper level ridge building in from the west. 41 && .PRELIMINARY POINT TEMPS/POPS...

The Flash Flood Watch continues for * A portion of southeast Texas...including the following counties...Chambers...Harris...Liberty...Montgomery...Polk and San Jacinto. * Until 8 AM CDT Wednesday * Shower and thunderstorm coverage is expected to increase across portions of the watch area overnight. Storms that repeatably move over the same locations have the potential to produce rainfall rates of up to 3 inches per hour which could lead to flooding. High rainfall amounts over the past few days have led to saturated soil conditions in some areas, and any additional rainfall overnight could lead to flooding. PRECAUTIONARY/PREPAREDNESS ACTIONS... Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Vehicles caught in rising water should be abandoned quickly. If your vehicle stalls...abandon it and seek higher ground immediately. Rapidly rising water may engulf your vehicle and its occupants and sweep them away. Move to higher ground. A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. && $$
Seemed like several big storms in your area, Joseph. Our monsoons have temporarily left us; bringing warmer temps, but no humidity. I can live with that :)

Lol, that's good! Houston can always use a day without humidity.
