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

[jasons2k]

I got .52" which is decent. I drove through it on the Hardy Toll Road on the way home and winds looked like they gusted to the 60-70mph range. It was pretty intense. One of the road signs was hanging on by only the top two screws, flapping in the wind. It did look like a strong tropical storm for a brief minute.

When I exited Riley Fuzzel there was a full grown pine tree snapped in half. Other than than, just some limbs & other debris down. Not as bad the further north you go...

I'm glad I got some rain though

So does that mean more rain to come overnight here?? I am seeing alot of lightning to my west....

[vbhoutex]

Out of all that I got less than 0.10" today after a 101ºf high. Still a halfway decent lightning show this evening on the way in from Cypress.

[southerngale]

Well, I'm glad some of you guys got some rain. It was hot and sunny here all day! And the chances for the next few days are slim to none.

Morning e=mail from Jeff Lindner...

TD # 2:

Sickly look tropical system is what remains of 02 at the moment as nearly the entire system is void of deep convection. The combination of dry/stable mid level air to the north, and moderate easterly wind shear have taken its toll of the depression. Not sure if the system will survive the rest of the day unless deep convection develops.

Track:

If the system does survive the track will be more westward as it has not gained much latitude and remains weak suggesting the mid Atlantic trough will bypass 02. This is confirmed by the latest guidance track reasoning showing a more westward track led by the GFDL, GFS, and EURO. The HWRF continues to show a turn into the weakness and is well north of the rest of guidance and NHC. In fact the NHC track is north of most of the models this morning and some additional adjustment southward may be needed.

Intensity:

The cyclone has failed to intensify as of yet and looks on the verge of becoming a remnant low. Without deep convection the surface circulation will spin down over time. Will keep the depression as such through the next 24 hours where there appears to be some better conditions for gradual development as the easterly shear abates some.

90L:

Large area of low pressure off the west coast of Africa has been declared 90L. While the cloud pattern suggest organization there is little convection within the system. Conditions are favorable for development of this area as if moves westward. While the SHIPS intensity guidance suggest rapid intensification…the broad nature of the system suggest more gradual strengthening over time. Guidance is in good agreement on a due west track south of the sub-tropical high over the eastern and central Atlantic.

Local Weather:

Widespread thunderstorms yesterday afternoon brought wetting rains to our parched southwestern counties. Widespread amounts of 1-3 inches with isolated totals up to 4-5 inches fell over southern Fort Bend, Wharton, Colorado, Jackson, Matagorda, and Calhoun Counties. Weak frontal trough remains parked over the area roughly along a line from Lake Charles to Conroe to College Station with a moist and unstable air mass south of this boundary and slightly drier air mass north. Given morning heating expect to see thunderstorms break out again especially over our SW counties where greatest moisture resides. Mesoscale 4km model shows development along US 59 pushing SSW from mid-afternoon onward and then a few storms going up from N Waller to N Liberty Counties late this afternoon.

Ridging builds in Friday and Saturday with drying conditions and warmer afternoon highs.

Sub-tropical ridge builds westward Saturday allowing tropical wave north of the Caribbean Sea this morning to move into the SE Gulf of Mexico by late Saturday. Aggressive model development yesterday with this feature is not maintained today and will continue to favor the less amplified solution of an open tropical wave/inverted trough moving WNW across the Gulf early next week. Main impacts will be to increase winds over the waters and bring deep tropical moisture to the area to enhance a more robust display of seabreeze convection each day starting as early as Sunday and on into much of next week.

[Ptarmigan]

The folks in Fort Bend, Wharton, Colorado, Jackson, Matagorda, and Calhoun Counties needed the rain much more than we needed.

[jasons2k]

And like a light switch, there are lots of storms going-up to the north of Houston. Looks similar to yesterday, just a little earlier in the day....

I thought most of the activity was supposed to be in the SW areas today...oh well I'll take the rain again (knock on wood).

[Flyinman]

Definitely take the rain. I am activating my super vacuum to get the storms to move more west . I too am glad to see them developing earlier in the day but please stay away severe weather.

[srainhoutx]

Today, the shortwave appears to be just a bit further E than yesterdays rainfall event (shortwave) that provide Central TX with some rain...

[Yankeegirl]

Looks like some action to the north of here... Hope it makes it down in this direction later in the afternoon!! Its HOT out there!!!!

At the moment, the convection is doing a little dance around my house. The outflow has pushed ahead of the main line so more storms should go up closer to Houston itself soon.

Just as I had feared...old line falling apart as it gets into Southern Montgomery county and the new line is taking over in Northern Harris. I get left with some leftover sprinkles from a decaying cloud....maybe bext time...

[mpic]

I'm down here south of Clear Lake like the guy on the runway giving a plane directions...trying to coax it to my house!

I'm in Baytown.... I'll let you know how it goes. just dark clouds and thunder now...

[vbhoutex]

Danced all around my place too. Lots of noise close by and a good cool down from the outflow boundaries as they came through, but that's it so far. Still managed 100ºf before it moved in.

[srainhoutx]

Not a drop at my location. No thunder, no wind, just a little cloud cover to cool me off from yard work.

[Flyinman]

It poured from I-45 to about 7 miles west into The Woodlands..Then nothing..Guess where I am..The nothing part. We did get a little left over rain but that was about it. MAybe next week.
