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

[Stratosphere747]

Whoa!

Now this is impressive! Even using the EWG scale on gusts... Solid gusts of 50/60 with small hail.

[Stratosphere747]

Little white showing up with the storms near Beaumont.



*Edit* 6:10 - This has to be about the most cloud to ground lightning I've seen in quite sometime.

[southerngale]

Wow! 54mph gust confirmed via KFDM - with a current rain rate of 4.60/hr.

Edit: Make that 4.80/hr. rain rate.

[Stratosphere747]

A bit surprised they took down the svr t-storm warning here. Where was that gust recorded Kelly? I know at my hotel off I-10 and 69 there were gusts in that range.

At Price E.S. in Beaumont. I heard Greg talking about it on the news. You can see the highest gusts at various locations through KFDM's Instaweather. It doesn't show the highest rain rates, however, just the current ones. It does show rain totals though.

Some of them don't work, but you can tell which ones... like the ones in the middle of the storms that show zero rain, etc. lol

Nice to have observations like that. Looks like the storms are finally winding down a bit in the Beaumont area, though rain is coming down at a decent rate. Still nasty storms to the south towards Nederland and Port Arthur.

[JenBayles]

The Dome has held all day, and we've been teased with thunder from storms all around us and maybe 3 drops of rain. DRAT!

[Yankeegirl]

I totally agree Jen, Its all black to the south of me and thundering... but no rain... It did pour at work this afternoon around noon-ish...

[srainhoutx]

Good thunderstorm going at my location for the past 1/2 hour. Lots of thunder and lightning and heavy rain. Yard needed it.

[jasons2k]

Big storms going-up NW of the Galleria area - looks like the "dome" is the bullseye today. I'm afraid that outflow now pushing east is going to pop some storms right over me just in time for the commute home....

[Yankeegirl]

Yes, the dome was nailed today!! I just now turned on the computer.. the power didnt know if it wanted to stay on or off... crazy lightning too!!

[jasons2k]

Luckily I left early yesterday and beat the rain.

It sure is pouring here near The Galleria - and quite a lightning show to the west.

[southerngale]

Anyone else getting intense storms this afternoon? It's pouring here... lots of thunder and lightning too.

We've been getting a lot of cloud to ground lightning with the storms lately. A 25 year old man was killed in Port Arthur a couple of days ago when he was struck by lightning.

And last night around midnight, a middle school was struck by lightning, which started a fire, and they had to close the school.

I don't know how many, but there are power outages in the Beaumont area right now. *crosses fingers* Please don't go out here!

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
842 PM CDT FRI AUG 31 2007

.DISCUSSION...
CLUSTER OF THUNDERSTORMS FROM DOWNTOWN HOUSTON ESE TO THE BOLIVAR
PENINSULA HOLDING TOGETHER AFTER SUNSET WHILE MOVING SOUTHWEST
NEAR 20 MPH. SOUNDINGS SHOW OVER 2 INCHES PW AND NO CAP SO MESO
BOUNDARY INTERACTIONS SUFFICIENT TO MAINTAIN SOME CONVECTION AFTER
DARK. NORTH OF I10 MOST ACTIVITY GONE FOR TONIGHT. WILL ADJUST
POPS SLIGHTY HIGHER COASTAL COUNTIES TIL AFTER MIDNIGHT AND LOWER
POPS NORTHERN HALF. OTHERWISE CURRENT FORECAST WORKING OUT WELL. 30

.PREV DISCUSSION... /ISSUED 259 PM CDT FRI AUG 31 2007/

DISCUSSION...
THERE IS A LITTLE MORE THUNDERSTORM ACTIVITY ONGOING COMPARED TO
YESTERDAY. MOST OF THE ACTIVITY IS MOVING TO THE SW WITH MAINLY
NE TO N FLOW ALOFT PER VAD WINDS AND WIND PROFILERS IN THE AREA.
ONE CLUSTER CONTINUES TO HOLD TOGETHER OVER HOUSTON/TRINITY
COUNTIES WHICH WILL PROBABLY AFFECT THE HUNTSVILLE TO COLLEGE
STATION AREA OVER THE NEXT COUPLE OF HOURS IF IT HOLDS TOGETHER.
THE OTHER AREA OF STORMS TO WATCH IS OVER THE COASTAL PLAIN
TOWARDS MATAGORDA BAY. THUNDERSTORMS ARE MOVING SO FLOODING HAS
NOT BEEN MUCH OF AN ISSUE EVEN WITH SOME RAINRATES AROUND AN INCH
AN HOUR. AGAIN EXPECT THIS ACTIVITY TO DIE OFF TOWARDS SUNSET.

A WEAK DIFFUSE FRONTAL BOUNDARY MAY HANG ACROSS THE AREA BUT IT
WILL QUICKLY DISSIPATE. DRIER AIR LOCATED OVER ARKANSAS IS STILL
FORECAST TO SHIFT INTO SE TX MAINLY OVER THE PINY WOODS OVER TO
THE BRAZOS VALLEY. DOUBT IT WILL MAKE IF AS FAR SOUTH AS I-10 SO
WILL STILL CARRY SOME CHANCE THUNDERSTORM POPS OVER THE WEEKEND.
THE 12Z NAM/GFS SOLUTIONS SEEM TOO MOIST GIVEN NE TO E 850MB FLOW
EXPECTED TO PERSIST TOMORROW. CURRENT WATER VAPOR IMAGERY DOES
PICK UP A DEVELOP UPPER LOW OVER W CENTRAL TX AND THIS WILL LIKELY
BECOME A PLAYER IN THE WEATHER EARLY NEXT WEEK BUT SHOULD NOT BE
MUCH OF A INFLUENCE FOR THE WEEKEND.

BETTER MOISTURE IS EXPECTED TO RETURN TO SE TX MAINLY SUN THROUGH
TUE NEXT WEEK WHICH BRING BACK DECENT POPS AS WELL. THE FORECAST
WILL UNDERCUT GUIDANCE A BIT BUT KEEPS SOME HIGHER POPS OFF
TOWARDS MATAGORDA BAY WHERE MOISTURE WILL BE BETTER. A DIGGING
TROUGH OVER THE ROCKIE MOUNTAINS EVENTUALLY PICKS UP THE UPPER
LOW INTO THE WESTERLIES WED INTO THU SO MAY SEE POPS TAPER OFF A
BIT TOWARDS THE END OF THE WEEK. THE EXTENDED RANGE IS NOT AS
OPTIMISTIC WITH THE COLD FRONT AS PREVIOUS FORECASTS. THE PATTERN
IS LESS AMPLIFIED THAN BEFORE WHICH WOULD LEND TO THE FRONT
STALLING. AN UPPER LEVEL RIDGE ALSO REMAINS QUIT STRONG OVER THE
W ATL AND E GULF LATE NEXT WEEK WHICH WILL BE DIFFICULT TO BREAK
DOWN. FOR NOW THE FORECAST WILL CONTINUE WITH PREVIOUS TRENDS OF
MAINLY AFTERNOON THUNDERSTORM ACTIVITY WITH THE TYPICAL GULF
MOISTURE IN PLACE.

MARINE...
THE LIGHT PRESSURE GRADIENT WILL PERSIST FOR THE NEXT SEVERAL DAYS
RESULTING IN PERIODS OF VARIABLE WINDS AT 5 TO 10 KNOTS. A LIGHT
NORTH WIND MIGHT STILL END UP BEING THE PRIMARY DIRECTION OBSERVED
UNDER THIS REGIME. AN ONSHORE FLOW IS STILL ANTICIPATED TO RETURN TO
THE AREA ON TUESDAY AND STRENGTHEN BY WEDNESDAY IN RESPONSE TO
LOWERING PRESSURES TO THE LEE OF THE ROCKIES. 1 TO 2 FOOT SEAS ALL
THE WAY THROUGH TUESDAY WILL BEGIN TO RISE TUESDAY NIGHT AND
WEDNESDAY. CAUTION FLAGS MIGHT BE NEEDED AROUND MIDWEEK NEXT WEEK. 42

AVIATION...
AFTERNOON CONVECTION WILL COME TO AN END THIS EVENING. WE COULD SEE
SOME DEVELOPMENT AGAIN OVERNIGHT...BUT CONFIDENCE IS LOW ON WHEN
THIS WILL HAPPEN OR WHERE IT MAY OCCUR. WITH DEEPEST MOISTURE LEVELS
NEAR THE COAST...HAVE STUCK A VCSH IN ONLY THE KGLS TAF. HAVE ALSO
MENTIONED SOME OVERNIGHT PATCHY LIGHT FOG AT A COUPLE OF OUR INLAND
TAF SITES NORMALLY PRONE TO FOG FORMATION. HAVE GENERALLY GONE WITH
VFR CONDITIONS FOR BOTH TONIGHT AND TOMORROW MORNING. 42

Looks like all the rain and storms are all around Houston... Good for us!!

[southerngale]

I guess heavy rain every day is the norm again. Nothing like driving down I-10 at 40mph, going faster than most of the people around you... well, you *think* there's people around you, but you can't see very well.

It rained off and on again yesterday, then heavy thunderstorms last night that lasted quite a while. Already a lot today, with minor street flooding as I was out this afternoon... nothing serious. Heavier storms seem more plentiful lately.. with those high rain rates/hour.

We probably won't be swimming or grilling tomorrow as there's a 70% chance of thunderstorms. But who knows? Maybe it will be hit and miss and we'll get some miss. If not, it's Phase 10!

Hope everyone is enjoying their wet Labor Day weekend.... at least the temps are a lot lower!

[Yankeegirl]

No rain here today... Just a lotta sun, which is good since we are having a BBQ today... But my leg is hurting, so I know the rain is on the way.... Maybe later tonight when Im toasted it will rain??
