A rough day across SE TX on Friday with a large long lived destructive bow echo moving from south of San Antonio to Galveston Island in about 6 hours and then all the way to SC Louisiana. Widespread wind damage and power outages especially across southern Fort Bend, southern Harris, and Brazoria Counties. Intense meso low formed over SW Fort Bend County helping to bow out the leading edge line into Brazoria County. Radar reflectivity was nearly 65dbz over western and central Brazoria County indicating very large hail. Hobby Airport tower radar was recording inbound radial velocities above the surface or 90-100mph. Town of Angleton, TX was especially hard hit with tennis ball size hail driven by sustained winds near 75mph…resulting in extensive damage. Meso low intensified over southern Harris County resulting in incredible rainfall rates and rapid flash flooding. This was one of the most intense bow echoes I have ever worked in SE TX with radar velocities frequently pegging 100mph along its 6 hour track….such events are more common over the central plains, Midwest and northern plains in the summer months. However the last 48 hours have produced a large long track tornadic supercell on Thursday afternoon and then the bow echo yesterday afternoon.
As of 1000am this morning there are still over 40,000 residents without power over Brazoria, southern Harris, Fort Bend, and Galveston Counties…the areas hard hit with the bow echo. Power has been out at some locations for over 14 hours.
Note: At one point last evening the National Lightning Detection Network was recording over 6500 strikes in 10 minutes over SE TX.
