OMG!!! I have never seen anything like this in all my years!!!
It did turn into a hailstorm again-pea to marble size- for at least 15 minutes!!! We are flooded in(local street flooding) with 2" and counting in the gauge. We have had winds to about 30 mph in gusts. When will it stop????? AAAAARRRRGGGGHHHHHH!!!!!

Jason are you seeing rotation in the hook off to the west of Hwy 6, just north of IH10?

JenBayles · #164 Postby **JenBayles** » Thu May 10, 2007 8:26 pm

Lost power for a few minutes. YIKES!! The cells from our West in Waller county appear to be merging with the existing severe storms in west Harris county. David, it's gonna be a while for you. :eek:

I know what that feels like. Sounds a lot like the hail storm I saw a year ago. We got three rounds and it lasted for 30-60 minutes. Seemed like it would never stop!

What is the damage status in your area right now?

#166 Postby **srainhoutx** » Thu May 10, 2007 8:30 pm

pea size hail at this time HWY 6 N/ Huffmiester

JenBayles · #167 Postby **JenBayles** » Thu May 10, 2007 8:30 pm

Continuous lighting under the Bear Creek Dome and heavy rain. Street is filled up... I feel like I'm back in Kansas again.

Looking at the radar loop, I think it'll be done here in a short time. Now for David, you got a ways to go yet...

#168 Postby **jasons2k** » Thu May 10, 2007 8:32 pm

We had some 40-50 mph gusts. Heard a few pings of hail but nothing major. Storm reports show 1.75" hail just a couple of miles form here.

David, one time in Lubbock I got hail from 5 seperate cells in April 1997 (there were 14 tornadoes on the South Plains that night). I probably had hail falling for about an hour total between the 5 storms. I've never seen anything close to it since.

Here are some radar shots in the last 30 min. One shows some real intense stuff by the airport:

I would expect a flood warning soon for at least Harris:

jschlitz - when this even is over, will you please start a new thread and tell me (and others with declining minds!) how to capture the radar images you've been getting? Really nice job for posterity by the way - thanks!

Yankeegirl · #171 Postby **Yankeegirl** » Thu May 10, 2007 8:37 pm

We havent lost the power here yet... seems like its dying down right now though...

It's not a true hook. It's an illusion as the storm from the NW merged with the one already there, it generated a hook-like signature on radar. It's linear.

all is quiet here now... think its over for the night?

Extremeweatherguy · #175 Postby **Extremeweatherguy** » Thu May 10, 2007 9:34 pm

well the storms have moved on off from my area without dumping any hail. However, heavy rain, lightning and a burst of 50-60mph winds that lasted 1-3 minutes sure made this an exciting night. The wind even did some minor damages in this area. Can't wait to see what daylight brings.

#176 Postby **jasons2k** » Thu May 10, 2007 9:49 pm

There is a brand new cell popping up west of here & also near Sugar Land.

OH - Fox 26 did it again - this time the "Doctor". He said radar estimated 9" on rain in NW Harris County.

I'm sure quite a chunk of that was hail contamination.

Ptarmigan · #177 Postby **Ptarmigan** » Thu May 10, 2007 9:53 pm

Lots of rain fell and plenty of lightning. NWS Doppler radar estimates up to 6 inches of rain fell.

weatherrabbit_tx · #178 Postby **weatherrabbit_tx** » Thu May 10, 2007 9:56 pm

moderate rain now, thunder/lightening seems like its forming right on top of me here in northern part of tomball, the rain is getting heavier.......

#179 Postby **jasons2k** » Thu May 10, 2007 9:56 pm

It's hard to see it unless you loop - but the outflow is really pushing SE in the SE part of Harris County and it is wrapped into a Meso-Low forming up near Kingwood:

I'm also getting new rumbles of thunder here now...

Thanks Jen! I tried to post earlier but that's when the board went kaput.

Anyway, I use GRLevel3 with many, many, many hours of customization to get it to look that way. I also pay for the Allisonhouse data subscription.
