CONCERNING...TORNADO WATCH 203...

VALID 272330Z - 280130Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 203 CONTINUES.

CONTINUE WW ALONG/AHEAD OF SVR/QUASI-LINEAR MCS NOW EXHIBITING NET
MOTION SEWD 20-25 KT. TORNADO THREAT WW SHOULD BE CLEARED BEHIND
THIS COMPLEX...GIVEN STG LEADING-EDGE OUTFLOW BOUNDARY...MESOHIGH
ANALYZED TO ITS N...AND RESULTANT DISRUPTION OF BOTH SHEAR AND
BUOYANCY BEHIND INITIAL CONVECTION.

SVR AND HEAVY RAIN POTENTIAL WITH MCS MAY EXTEND EWD ALONG COASTAL
COUNTIES TOWARD SABINE PASS AREA. SVR GUST MEASURED 50 KT AT VCT
DURING PAST HOUR...AND RAIN RATES TO 3 INCHES/HOUR WILL REMAIN
COMMON. GIVEN NARROW LAND AREA AFFECTED AND FCST LOSS OF SFC
HEATING -- EVENTUALLY REDUCING SFC-BASED BUOYANCY -- WHOLE NEW WW IS
NOT ANTICIPATED ATTM. HOWEVER...AS CONVECTIVE TRENDS WARRANT...A
FEW ADDITIONAL COUNTIES MAY BE TACKED ONTO ERN EDGE OF WW 203 IN WFO
HGX DOMAIN...AS WITH LIBERTY COUNTY ALREADY. ACTIVITY IS BEING
SUPPORTED BY RICH BOUNDARY LAYER MOISTURE AND FAVORABLE LOW LEVEL
SHEAR -- WITH SELY/ONSHORE SFC WINDS TRANSPORTING PW TO 1.75 INCH
BASED ON GPS READINGS AND MODIFIED RUC SOUNDINGS. LOW LEVEL
STORM-RELATIVE INFLOW WILL REMAIN STG...BETWEEN THOSE SE WINDS AND
30-40 KT SLY-SSWLY LLJ EVIDENT IN HGX/CRP VWP. THIS SHOULD AID BOTH
IN POTENTIAL FOR MESOCYCLONIC SPINUPS ALONG LEADING EDGE OF
MCS...AND IN PRECIP EFFICIENCY AS SLAB OF MARITIME/TROPICAL AIR IS
FORCED ABOVE COLD POOL.

[JenBayles]

Just got power back after an hour+ outage. Street flooded, but not as badly as a couple of weeks ago. Along with the torrential rains, the wind kicked up incredibly a few times and actually blew the chimney flue open. Scared the crap out of me and Dave - along with the dogs and birds.

We have sump pumps in the back yard, but when it comes up from the front there isn't a dam thing we can do other than raise important things up as high as possible.

Did someone say another "event" is probable this coming Sunday?

Getting dark again and hearing more thunder. If it will hold off another 30 minutes we just might make it with no water in homes here in Bear Creek.

[setxweathergal]

Can anyone tell me if/when these storms will be in the Beaumont area?

[southerngale]

It's usually still light outside, but it's really dark and started seeing lightning and hearing thunder a few minutes ago. We had a heavy shower earlier, but it was brief. A little light stuff on and off, but now it looks like the main enchilada will be here soon.

I'm not liking what I'm seeing on radar.

Will someone check the Austin and San Antonio radars for me? Please tell me that's false echos I'm looking at and not redevelopment for tomorrow?

[srainhoutx]

Looks like strataform rain for us Jen, but nothing back W. What an afternoon/evening.

[southerngale]

I know it may not end up being severe (as is often the case), but this is headed right for me. The radar looks mean.
