1-minute Mesoscale Domain Sector GOES-16 (GOES-East)<\/em> Visible\/Infrared Sandwich RGB<\/strong><\/a> images from 1300-1800 UTC (above)<\/strong><\/em> included plots of 1-hour surface precipitation amounts — and showed clusters of thunderstorms moving across North Texas and the greater Dallas\/Fort Worth area early in the day on 22 August 2022<\/strong><\/a>. These storms were focused along a quasi-stationary surface front that was draped across the region; heavy rainfall during this 5-hour period caused additional flash flooding in locations that had already received substantial precipitation within the previous 24 hours.<\/p>\n

A GOES-16 Visible\/Infrared Sandwich RGB image at 1410 UTC (below)<\/strong><\/em> displayed cursor readouts of the 3 RGB components along with the available Level 2 Derived Products — cloud-top infrared brightness temperatures were colder than -80\u00baC, Cloud-Top Heights were greater than 54,000 feet and Rainfall Rates were nearly 3.7 inches per hour just south of Terrell, Texas. The Dallas\/Fort Worth airport received a record 3.01 inches of rain in 1 hour (tweet<\/strong><\/a>). <\/p>\n

Hourly MIMIC Total Precipitable Water<\/strong><\/a> images viewed using RealEarth<\/strong><\/a> (below)<\/strong><\/em> depicted TPW values in the 60-70 mm (2.4-2.8 inches) range, with a peak value of 78 mm (3.1 inches). The 22 August \/ 00 UTC rawinsonde report<\/strong><\/a> from Fort Worth had a TPW value of 2.34 inches, which was a record maximum value<\/strong><\/a> for that date\/time.<\/p>\n

At 1pm the 24 hour rain totals range from 15.16" in east Dallas (White Rock Creek @ Scyene) to just 0.82" at McKinney airport just 25 miles away. #dfwwx<\/a> #txwx<\/a><\/p>— NWS Fort Worth (@NWSFortWorth) August 22, 2022<\/a><\/blockquote>
