SE TX/SW LA weather: Much cooler and WET after Tuesday

[vbhoutex]

Houston metro storm reports from Jeff Lindner:

Busy afternoon across Harris County with large severe thunderstorms erupting along southward moving outflow boundary and colliding seabreeze front. End result was hail and wind damage across the county with the worst being in a corridor from The Galleria to Rice University to Hobby Airport where multiple microbursts resulted in wind damage and a wall collapse at Rice University



Houston, Harris: ***1 fatal and 7 inj*** Estimated winds to 60mph resulted in second floor brick wall collapse under construction on construction workers seeking shelter. Isolated nature suggest microburst as thunderstorm core collapsed



Houston, Harris: Hobby Airport ASOS recorded 66mph wind gust and pea size hail. 1.31” of rainfall in 24 minutes. Airport microburst detection system indicated microburst in the region likely resulting in the 57kt wind reading at the ASOS site.



Jersey Village, Harris: nickel size diameter hail at US 290 and Huffmeister



Jersey Village, Harris: walnut size hail at FM 529 and SH 6



Copperfield, Harris: damaging winds blew down wooden fences in subdivisions



Pasadena, Harris: Dairy Queen sign blown down at Strawberry and Pasadena Blvd



Houston, Harris: pea size hail report by NWS employee at I-45 S and Beltway 8



Houston, Harris: Public reported nickel size hail and strong winds 5 miles SE of Hobby Airport



Wharton, Wharton County: penny size hail increased to nickel size before ending.



Next upstream complex is already ongoing over W KS and NW OK and its remains/outflow should arrive into SE TX on Friday…resulting in another round of strong to severe thunderstorms.

Good view of Meso tonight...

I dont like the looks of the storms up by the dallas area... wonder if they will meander their way down to the houston area? we got one heck of a storm here today... had a few large pine tree branches fall on the house, luckily no damage to the house... but we had to get a chain saw to cut them up and get rid of them cause they were so big... We got lucky...

[jasons2k]

No updates from Jeff yet.

My gut feeling is that there is still much uncertainty with what to do with today's rain chances. The MCS is dead now and winds all across SE Texas are very light and mostly from the West. There doesn't seem to be much of a boundry except the seabreeze, and any storms that do form will create their own outflow boundries. In a nutshell, it's anyone's guess where exactly storms where fire (except along the seabreeze) and 50/50 odds look good for now.

[srainhoutx]

Have to agree with you Jason. With lack of early morning cloud cover from last nights MCS for our area, 50/50 seems reasonable. Still a lot of moisture to work with during max daytime heating along various boundries...

OVER THAT REGION THIS MID MORNING. ISOLATED CELLS FIRING UP ALONG

Just had a nice little shower and now out comes the sun. Oh the humidity is arising!

[jasons2k]

Hopefully the show will start soon. Impressive outflow from collapsing Galveston County storms now approaching the south loop/I-45 area. Maybe, just maybe, if some decent storms get going over Houston metro they can push another outflow north into Montgomery County later on....we shall see.....

I didn't end up getting anything yesterday, although it was hard to tell that on radar. The storms were close.

After about an hour of intense thunder, we just had a good thunderstorm. Boy, these storms are moving slow!

Hopefully the show will start soon. Impressive outflow from collapsing Galveston County storms now approaching the south loop/I-45 area. Maybe, just maybe, if some decent storms get going over Houston metro they can push another outflow north into Montgomery County later on....we shall see.....

Cool the way that boundary is spreading out in a near perfect circle. Like a pebble in a pond. Looking out the window, it has fired up a cell South of the Galleria.

[jasons2k]

Looking good so far....today might be my lucky day!

Good to see some well needed rain.

[srainhoutx]

Only a sprinkle here today. But did get the yard done.

[jasons2k]

Rain all around, but I got .01" - missed yet again.....

A FAIR AMOUNT OF UNCERTAINTY CONCERNING AFTERNOON INLAND
CONVECTION. ISOLATED OFFSHORE THUNDERSTORMS...WITH NO DISCERNIBLE
SEA BREEZE DEVELOPMENT AS OF 17Z...HAS PUT SOME DOUBT INTO WHETHER
HUBS WILL SEE ANY SIG CONVECTION THROUGH THIS EVENING. 18Z TAF
PACKAGE WILL HANG ONTO THE IDEA THAT...DUE TO EFFICIENT INLAND
HEATING AND VICINITY BOUNDARY INTERACTIONS WITHIN AN UNSTABLE
ENVIRONMENT PER MORNING`S RAOBS...NORTHERN AND CENTRAL HUBS WILL
EXPERIENCE LATE AFTERNOON CB`S WITH POSSIBLE VCTS/SH. HUBS SOUTH OF
HOUSTON METRO MAY SEE ACTION LATER IN THE EVENING...AND QUITE
POSSIBLY...PAST MIDNIGHT INTO EARLY SUNDAY...AS TODAY`S OFFSHORE
CONVECTION MAY TAKE AWAY INFLOW FROM ANY DEVELOPING CBS BUT...WITH
A LINGERING NEAR-STATIONARY FRONT PARALLELING THE COAST AND GULF
STORM OUTFLOW BOUNDARIES DRIFTING INLAND...BOUNDARY INTERACTION
WITH A WEAK NOCTURNAL LAND BREEZE MAY AID IN FIRING OFF EARLY
MORNING -TSRA OVER OR AROUND THE ISLAND. FOR WHAT IT IS
WORTH...MODELING DOES SUGGEST ENHANCED (NEAR) COASTAL
PRECIPITATION IN THE OVERNIGHT HOURS. 31

I have to disagree with the doubt over inland convection. To me, it looks like TCU and some storms are popping from Franklin to Crockett and Nacagdoches and this area will increase in coverage and move south into the Houston metro area later this afternoon. JMO!!

[srainhoutx]

HGX Update sounds reasonable.

STRONG TO SEVERE THUNDERSTORMS HAVE BEGUN TO DEVELOP ALONG AND AHEAD
OF THE WEAK SOUTHWARD MOVING FRONTAL BOUNDARY ACROSS OUR NORTHERN COUNTIES
AND FURTHER SOUTHWARD ALONG THE IMMEDIATE COAST AND A LITTLE BIT INLAND
WHERE A SEABREEZE FRONT CONTINUES TO TRY TO GET ORGANIZED. EXPECT ACTIVITY

Going to enjoy some pool time in the meantime.

[PTrackerLA]

Still waiting for a big soaking here. We've had a few showers over the past week but the heavy storms have all missed my area. Hopefully we'll get a good storm later today as it appears to dry out and heat up starting tomorrow.
