Video of the thunderstorm passing over my house in northwest Houston, TX.


Summary: The day was warm, mostly cloudy, and windy. Lots of rain. mostly during the night. Light to moderate rain and drizzle passed over the Houston, TX area during the afternoon and evening. A line of heavy thunderstorms passed over the Houston, TX area, during the night. I started to see on and off light to moderate drizzle in west Houston, TX, where I work, sometime during the early afternoon. The on and off drizzle continued up through the early evening. I also saw a few brief moderate showers in west Houston, TX, where I work, during the afternoon. A line of heavy to really heavy thunderstorms passed over my house, during the early night bringing 30 to 40+ maybe even to 50, or 60 mph wind gusts with loud rumbles of thunder and some possible cloud to ground lightning. The wind speeds were calm with moderate to moderately strong gusts and some really strong 20 to 25 mph gusts, during the morning, afternoon, and evening. There was a wind advisory issued up until the early night. Then there were several sever thunderstorm watches, warnings and statements with tornado watches and flood watches/advisories issued for the Houston, TX area, during the night. The low temps were in the 60's and the high temps were in the 70's with maybe a few 80's, for the Houston, TX area. There was no damage from the showers and thunderstorms that I know of, other than my thermometer that broke as it was carried by the wind from the thunderstorms. There might have been some flash flooding. Rain was reportedly dropping between 1 to 2 inches per hour in some locations.


Locations: Northwest and west Houston, TX.


Thoughts: I was excited to see the thunderstorms. I was not happy about my thermometer breaking, but oh well.

My broken thermometer.

AVIATION...
Cluster of storms has managed to get going across western portions
of se Tx. Short term hires guidance suggests this, or a portion
of, this cluster will maintain itself for the next 4-6 hours as
it treks eastward toward the I-45 corridor. Storms between CRP &
SAT have been losing their luster the past several scans & will
monitor that area to see if capping wins that battle. Appears main
time period for possible impacts to the Houston area airports
will be between 1-5z. May see another thin band of shra and/or iso
tsra develop along the front itself as it passes from CXO to the
coast between 10-14z. VFR conditions should prevail from mid
morning onward Sat. 47
