Gulf: Tropical Storm Hermine

[Nick Biermann]

Selected forecast soundings available from http://www.stormchaser.niu.edu/machine/fcstsound.html using the 8 Sept 0z NAM indicate between 100-400 J/Kg CAPE and 200-400 m^2/s^2 0-3 km SRH across central/southern/SW Oklahoma by 21-0z tomorrow afternoon. If we can get some breaks in the overcast and a few good updrafts develop in Hermine's rainbands, I certainly wouldn't rule out the possibility of tornadic spinups. I will definitely have my camera charged and ready to go after work.

Well after 4.66 inches in 12 hours yesterday I just got an additional 4.72 from midnight CDT to 3:30 am. Been up helping my neighbor bail out, siphon, and pump his side yard that was under 6 inches of water from a clogged drain. When I went to bed the rain train was SE of me from Seguine to San Marcos to just west of Austin, shoulda realized that a northerly trend would bring that beast right back to me..... <face palm>. Now to try and get some sleep before work.

Multiple tornado reports around the Dallas/Fort Worth area, and a couple along the OK/TX border. Wondering if anyone got any footage.

Well, I tried... Left from work around 530pm and spent much of the evening between Ardmore and Marietta but still didn't manage to get on the right cell. Saw some rising scud and "funnel-like" clouds but not anything rotating. I'll look over my pics and add a response to the reports thread if I find anything interesting...

I was spotting in south east Collin county and went over to Rockwall after that. Saw a brief wall cloud that had slight rotation but it died out few minutes later. By the time the cells moved past Dallas, they began to weaken. Mainly became rain systems.

Hermine is an impressive cyclone. The surface obs and radar presentation across S TX have been spectacular for an inland tropical storm.

Again, it makes me wonder if the cyclone might have been stronger than operationally assessed at landfall. I'm sure the NHC is going to do thorough postanalysis on this, and it will be interesting to see if they make a posthumous upgrade to hurricane status (like they did for Cindy 2005). To be clear, I'm not suggesting this was a hurricane in TX-- I'm just wondering if it might have been at landfall, in MX.

It was extremely intriguing experiencing this storm as it moved just west of our area. According to the DFW NWS Aviation summary the morning of the storm, wind speeds were progged at 50 to 60 + knots starting "just above the ground" and looking up I could see the low clouds really racing NW along with higher clouds moving swiftly from more of a southerly direction, presenting quite a sheer.

With the racing low clouds and rounds of torrential rains, it reminded me of when I experienced the outskirts of Hurricane Ike when I had intercepted it in Deer Park, a suburb SE of Downtown Houston.

More than 10 inches of rain fell just SW of Downtown Dallas in the Arlington area, and all stations in our regions exceeded more than 5" in just several hours during the day of it's passage on the 8th.
