Nice call by the SPC with the slight risk across the area.

I don't think the storms will make it here, but at least someone is seeing some rain

Yeah..weird...

Just walked outside, still warm and humid at almost 10PM! But unfortunetly the "pulse severe thunderstorms" are living up to their name tonight. Storms in Polk and San Jacinto counties have dramatically weakend in the last couple frames of the radar loop.

[jasons2k]

It was pretty decent line up towards Huntsville earlier. Notice how the cell near Willis fell apart though. Not good news.

[svrwx0503]

Radar indicating hail core descending to the ground with the severe thunderstorm just southwest of Hunstville. The storm has also been showing a little mid-level rotation over the past several minutes.

[weatherguy425]

While the line as a while is breaking up, some cells are re-strengthening and becoming more discrete. Big hailer in southern Walker county!

Yes indeed! Radar indicating 3'' hail just southwest of Huntsville. Nice 71.5db core up around 23,000 ft with a storm top over 50,000ft. Watch out around New Waverly.

[svrwx0503]

The first hail core has dropped with a second one developing aloft around 25,000 ft. 4.37'' hail possible!

[weatherguy425]

Also some new echos just South and east of bryan, we'll need to watch those, along with more thundershoers within the band of light rain to our northeast.

[svrwx0503]

Large hail core dropping once again just south of Huntsville with a 78.5db return on the lowest tilt of the radar which up there is at about 7,000ft. Good bet that golf ball sized hail or larger might be falling about 4.5 miles south of Huntsville and 2 miles west of I-45.

It looks like that storm is taking on some supercell characteristics with a v-notch and mid-level rotation. Tornado threat remains very low as it is likely somewhat elevated as the surface cools down this evening.

That is an impressive chunck of ice falling to and striking the ground, svrwx0503. Rectify me if I am wrong, but would that size be grapefruit or very close to it?

Come on thunderstorms, coerce that cap to crumble & shatter.

[weatherguy425]

^svrwx, Storms to the west appear to be re-intensifying as well. Do you think some of these storms could at least make it into Northern Harris county before the night is over?

That would be closer to softball size; however some of it is likely melting before hitting the ground. I would expect mainly golf ball sized hail with the southern Walker county storm at this time.

[sleetstorm]

incredible lightning off to our WNW - hope we don't get hail, but would love the rain

I understand, unome. Yet, none of us have any control as to what those thunderstorms produce and where they dump their cargo.

The storms out west look to be falling apart as they move away from the frontal boundary where the best low level convergence is occurring. As the boundary gets closer later tonight, there could still be some isolated showers and thunderstorms around that might make it into the Harris county area as some models have been hinting at. The overall severe threat will be on the decline as we head towards midnight and we loose any surface based instability.

Thank you for clearing that up for me, svrwx0503.

Just hopin' for some rain!
