Quite a storm here in the spring branch neighborhood.
Tons of lightning, thunder, heavy rain. Power has already started flickering.

Hi Pros,

Thank you for all you do!
I am confused with all the posts on here.
I realize the weather is going to get treacherous however, I am so confused now, as to where.


Is the line along I 10 and south of same now? Into Sugarland or as far west as Katy?
Thank you!

Unfortunately the "where" is yet to be determined. Storms are rapidly developing and it's time for folks to get off the roads as soon as possible and ride out the storms at home. Stay safe everyone!

Hubby is not home yet and he usually is home by now. He doesn't watch the weather like I do. Hopefully he will be home soon.

I’ll tell y’all one thing - maybe stating the obvious - but today was the first day all summer it really felt like summer. The heat and humidity were very tropical feeling today.

I’m grilling fajitas and sweating bullets right now, watching the radar.

Hey — it may be hot, my t-shirt may be drenched, but this is still 100x more tolerable than freezing cold!!!

I think Stafford is hearing the thunder from the huge cell that is just to the north of us. I can't tell which way it is moving, but everytime I look it looks bigger with more red.

Flood threat increasing with storms to our West...

Mesoscale Precipitation Discussion 0222
NWS Weather Prediction Center College Park MD
756 PM EDT Thu May 09 2019

Areas affected...South-Central & Southeast Texas

Concerning...Heavy rainfall...Flash flooding possible

Valid 092355Z - 100355Z

Summary...Thunderstorms are expanding in coverage near the edge of
the mid-level cap. Hourly rain totals to 2.5" and local amounts
of 5" are possible.

Discussion...Thunderstorms are developing in proximity to a
thermal boundary near the edge of the mid-level cap in
south-central and southeast TX at the present time, which is
approximated by the 9C isotherm at 700 hPa. Other storms are
attempting to cross the US/Mexican border. Dew points are in the
mid to upper 70s within the capped atmosphere to the southeast of
the convection. Inflow is cyclonic at 10-15 knots out of the
southeast per VAD wind profiles. ML CAPE in the region is
impressively high -- 4000-6000 J/kg. Effective bulk shear of
40-50 kts exists in the area per SPC mesoanalyses.

Thunderstorms within such a volatile atmosphere tend to gain high
rain rates quite quickly. The mesoscale guidance -- mainly the
22z HRRR, 18z NAM CONEST, 18z Canadian, and to some degree the 12z
NSSL WRF have some idea of what's ongoing. The guidance shows
local amounts in the 3-7" range through 06z -- believe local
amounts of 5" are possible through 04z. The environment favors
mesocyclones which may choose to periodically train near the edge
of the cap as they move at a right angle to the mean 850-400 hPa
wind. Hourly rain totals to 2.5" should be possible in this
region. Since the area has received 200-400% of the average
rainfall over the past couple weeks, soils should be somewhat
saturated. Flash flooding is a concern.

Just hearing thunder here in Stafford. No lightning. The current storms are currently to the Northwest of us and appear to be pushing north.
