Something tells me the Bear Creek Dome will once again repel the coming storm. If we even get 1/4" out of this system I'll be surprised. Looks like it's going to go north of here. Again.

Hang on Jen, it's pouring just a bit N of you.

[JenBayles]

LOL! I see that. I also see the southern end of the line that might have hit us rapidly unraveling. How much you wanna bet it splits right at Bear Creek with half going north and half going south of us?

[CajunMama]

Nasty storms headed se towards frack. Stay safe!

[JenBayles]

I don't believe it. The Dome won again. Just a trace of rain, no lightning, no wind, no nada and it's all passed to our east.

[southerngale]

It's looking pretty wild outside. Thunder and lightning like crazy... heavy stuff almost here.

SNAVELY/SHAMBURGER

[southerngale]

This was the most intense storm I've seen in a while.... incredible lightning show with those loud boomers that make you jump out of your skin!
Very heavy rain - lost electricity briefly. So thankful that it came back quickly... it would probably still be out at my old house.

[setxweathergal]

No ma'am it wouldn't still be out cause it never even blinked !

[jasons2k]

The storms last night were some of the most intense I've seen in a long time.

I had wind gusts over 50mph. Haven't seen anything like that since Ike. Had some small hail and ended-up with 1.95" of rain yesterday. It looks like in the end I'll have more rain from this event than the rains we had last week!

[jasons2k]

This was from Jeff Lindner A 6:53 AM this morning:

Very active evening yesterday as squall line developed and pounded areas N of I-10.

Infamous surface boundary draped along a line from Wharton to just N of Galveston this morning with cool surface air north of this boundary and warm muggy air south. Sugar Land has a dewpoint of 60 with Palacios a dewpoint of 70. Surface boundary will begin to trek northward this morning as next short wave approaches from N Mexico...sound familiar.

Low clouds should burn off by late morning/early afternoon allowing good surface heating. Short wave induces mid level cooling resulting in a very unstable air mass by mid to late afternoon. Thermodynamic parameters (LI's down to -10 and CAPE of 3000-4000 J/kg) along with convective trigger temperatures in the mid to upper 70's point to an active afternoon. While 0-3km shear values are lower than yesterday the extensive to extreme instability will more than make up for the lack of shear.

Once trigger temp is exceeded and weak capping is broken expect to see rapid and explosive thunderstorm growth. Given the amount of low level and mid level instability, updraft speeds of 150-250mph will be possible if not common yielding a very large hail threat. Damaging winds will also be possible especially as storms congeal and begin to grown upscale into a linear MCS this evening...similar to Wed evening over Montgomery and Liberty Counties.

The tornado threat is a little more uncertain today given the weaker wind fields and lower amounts of low level shear. However locally higher shear will be found near the frontal boundary where low level winds remain backed out of the NE on the north side of the boundary. This boundary and about 20 miles either side were very favorable yesterday for mesocyclone formation and tornadoes....and may be such again today.

While the most favored areas today will be along and N of US 59 the coastal areas even Matagorda Bay will stand at least a chance of seeing some weather and wetting rains.

Friday-Sunday:

Strong winter storm system will drop into the southern plains with heavy snow and blizzard conditions from extreme N TX into Kansas. In fact snow may fall as far south as the Red River Friday night. Extensive amount of cold air will spill into the region after a powerful frontal passage late Friday. Most moisture will be swept eastward tonight and only meager amounts will remain near the surface. Expect only a few storms with the front late Friday. Strong cold air advection on NW winds will drive temps. well into the 40's by Saturday AM and will see slow recovery only into the mid 60's Saturday under cooling 850mb temps. Clear skies and light wind point to excellent cooling conditions Saturday night. Guidance continues to trend downward on lows for each run and some areas will likely see the mid 30's Sunday AM. Typical cold areas may hit freezing and given the amount of green up that has occurred in the last several weeks some sensitive vegetation may get nipped.

Wednesday Storm Reports:

Cleveland, Liberty: trees and power lines downed estimated winds to 70mph

Cut and Shoot, Montgomery: winds estimated at 60mph

Conroe, Montgomery: penny size hail at League Line Rd and I-45

5WNW of The Woodlands, Montgomery: 55-60mph winds

Huntsville, Walker: Tornado reported by law enforcement near Huntsville State Park at 754pm.

[southerngale]

No ma'am it wouldn't still be out cause it never even blinked !

LOL - well, that's good to hear. I'm just hoping I don't have as many power outages here as I did there.

[Johnny]

We also got slapped very hard just south of Lake Conroe Dam. The last time I saw wind gusts like that were, uh...well, Ike! That was a darn good storm last night. One of the best spring time storms I have seen in a good while. We did get pea size hail...sure am glad it wasn't any bigger than that. Round 2 should be here in the next few hours.

[jasons2k]

And another severe T-storm watch goes up for the SW 1/2 of the area. Gonna be another interesting day for sure. If we had more heating we'd be off to the races, but it looks like a marginal hail/wind event shaping-up.

[JenBayles]

May have Bear Creek Dome failure shortly. Lots of thunder rumbling to our SW and rain starting now.

[vbhoutex]

You guys on the North side got slapped hard last night. Looks like it is or turn further South today. Strong storms moving in as I type w/ plenty of cg. Doesn't look like we'll go severe, at least not yet. As for last night-some torrential downpours-short lived- producing 0.40" at the house. Finally washed all the nasty yellow pollen off the vehicle. Here's hoping for a dome failure Jen, However, not sure how much rain is really in these, at least the earlier ones, More following though. Looks like it could be a stormy/rainy afternoon.
