POLK TX-LIBERTY TX-
536 PM CDT FRI MAY 24 2013

...SIGNIFICANT WEATHER ADVISORY FOR POLK AND NORTH CENTRAL LIBERTY
COUNTIES UNTIL 600 PM CDT...

AT 527 PM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR WAS TRACKING
A CLUSTER OF STRONG THUNDERSTORMS ALONG A LINE EXTENDING FROM
CHESTER TO 11 MILES SOUTHEAST OF LIVINGSTON...AND MOVING NORTHWEST
AT 25 MPH.

HAIL UP TO THE SIZE OF PEAS AND WIND GUSTS UP TO 40 MPH WILL BE
POSSIBLE WITH THESE STORMS. IN ADDITION...BRIEF HEAVY RAINFALL WILL
BE POSSIBLE WITH 1 TO 2 INCH AMOUNTS REACHABLE IN THE STRONGER
ACTIVITY. FREQUENT LIGHTNING STRIKES ARE POSSIBLE TOO.

LIVINGSTON...CORRIGAN...ONALASKA...GOODRICH AND SEVEN OAKS.

Fri May 24, 2013 5:53 pm

Well, that line of storms out west is slowing and weakening as it tries to move east. May not make it here at all but I've not given up just yet. Strong storm moving toward Livingston now. I'm surprised we have not had more scattered storms pop up in the heat this afternoon. I saw some nice cu towers going up around 1:30 but too much of a cap to overcome for now.

Fri May 24, 2013 6:57 pm

high resolution HRRR did a great job with this activity suggesting little eastward movement. IT also caught the northern counties development well. None of the meso models suggested the SW TX activity would make it this far east. None suggest development tomorrow either, but boundaries will be closer in from the west and weakness aloft out west overhead...so I could see possibly more development than today on Saturday.

Slow moving MVC's in a moist air mass can really put down the rainfall as noted on 88D's out west. Much needed rain...but as usual way too fast.

Sat May 25, 2013 8:17 am

The flooding continues to our W in San Antonio this morning where 4 inches of rain fell in an hour at the airport. The 06Z HRRR is suggesting showers and storm may move a bit E toward Houston and SE Texas later this afternoon as a speed max drifts our direction in a very blocked pattern with little upper air flow aloft to push this along. We will see.

From NWS San Antonio/Austin:

San Antonio International Airport is now up to 9.57 inches for today. This is now the 2nd all time daily rainfall. No 1 is the 11.26 set on October 17, 1998. These rains are similar to that day.

Sat May 25, 2013 9:52 am

Is it just me or did this system sorta creep out of nowhere and is dumping a LOT more rain than anyone thought? We have friends in town from Austin and they were saying 'yeah, on the way to work yesterday the weather report said only about a 30% chance of rain and no big deal. Next thing you know, our building was flooding'.

It'll be interesting to watch this evolve today. I need the rain but of all times, it's suposed to be pool time.

Sat May 25, 2013 9:54 am

Update from Jeff:

NWS has issued a Flash Flood Emergency for Bexar County and the city of San Antonio.

This morning 8.77 inches of rainfall has fallen across Bexar County making this the all-time wettest May day on record and only 2 other days ever had recorded more rainfall in the city. Significant and life threatening flash flooding is ongoing across the San Antonio metro area including severe flooding of small creeks and the San Antonio River.

Heavy rainfall continues to focus in a zone of low level convergence and moisture influx from Austin to San Antonio to north of Corpus Christi. Rainfall rates of 2-3 inches per an hour have been common under these very slow moving thunderstorms leading to rapid flash flooding. Storms should gradually weaken with time this morning, but the tropical air mass in place will support additional rainfall of 1-3 inches on top of what has fallen.

Flash flooding is ongoing and many low water crossings in and around the San Antonio area. Avoid these crossings and if water covers the road…turn around Don’t drown.

Looks like we will miss out on much if any rain around SE Texas other than the Beaumont/Port Arthur/Lake Charles area. Fired up the smoker and filled it with a couple of hogs. Time to kick back and enjoy the Holiday weekend!
