 Flash Flood Watch  Statement as of 3:27 PM CDT on May 25, 2015


... Flash Flood Watch remains in effect until 1 am CDT Tuesday...

The Flash Flood Watch continues for

* a portion of south central Texas... including the following
areas... Atascosa... Bandera... Bastrop... Bexar... blanco...
Burnet... Caldwell... Comal... De Witt... Fayette... Gillespie...
Gonzales... Guadalupe... Hays... Karnes... Kendall... Kerr...
Lavaca... Lee... Llano... Travis... Williamson and Wilson.

* Until 1 am CDT Tuesday

* showers and thunderstorms are producing locally heavy rainfall
across south central Texas... causing up to 3 inches of rain per
hour in parts of The Hill Country and I-35 corridor. The heavy
rainfall threat will gradually end from west to east this
evening. Rainfall totals of 1 to 4 inches are expected... with
isolated amounts over 5 inches possible.

* Due to the very moist conditions of the grounds and soils in
the area... rapid flash flooding of low water crossings and
some roadways will be possible where heavy rains develop. Area
rivers and streams are also out of banks or in flood. Some of
these rivers and streams will reach their flood stages very
quickly.

Precautionary/preparedness actions...

A Flash Flood Watch means flash flooding is possible in or near
the watch area. If you are in the watch area... plan now for what
you will do if flash flooding develops. Stay informed and be
ready to act if you see flooding or if a Flash Flood Warning is
issued.

Do not drive into flooded roadways. Some roadways... low water
crossings... and bridges may be inundated or overtopped. If you
see water flowing over a roadway... do not try to pass! Remember...
turn around... dont drown.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
717 PM CDT Monday may 25 2015 


Aviation.../00z tafs/ 
storms have cleared all taf sites...but will include thunderstorms in the vicinity through 
01z for Sat/ssf/aus in case backbuilding storms produce a rogue 
lightning strike. A mesoscale low has formed behind this line...which 
will cause variable winds below 10 kts at Sat/ssf/aus for the next 
few hours...will handle this with amendments if they increase 
above 10 kts. Dry air evident on WV imagery will help dry out the 
middle and upper levels...but moist low level southeast flow will allow VFR 
ceilings to lower to IFR by 7z at Sat/ssf/aus and MVFR by 9z at drt. 
Model guidance suggests LIFR ceilings could develop between 10-14z at 
Sat/ssf/aus...but will reevaluate this with the 06z taf package.

Previous discussion... /issued 447 PM CDT Monday may 25 2015/ 


.Significant flash flooding ongoing across the northern and 
central parts of south central Texas... 


Short term (today through tuesday)... 
a strong negatively tilted upper level trough has caused a 
significant severe weather event that has already produced a few 
tornadoes in The Hill Country and widespread flash flooding in The 
Hill Country and I-35 corridor is ongoing this afternoon. A flash 
flood emergency has also been issued for eastern Williamson and 
Travis counties after 3 to 5 inches of rain fell in two hours. The 
primary threat for the next several hours will continue to be 
significant flash and river flooding...with the latter continuing 
into at least the overnight hours. Rainfall rates up to 4 inches 
per hour have occurred this afternoon...but these rates should 
begin to decrease slightly as these storms continue to merge into 
a line over the I-35 corridor from the San Antonio metropolitan and areas 
north before pushing east across our County Warning Area. Dry air moving in from 
the west evident on WV imagery should continue to cause precipitable water 
values to decrease and end the heavy rainfall threat from west to 
east as we move into the evening and overnight hours. Thus...the 
Flash Flood Watch has been cancelled for our westernmost 
counties...but continues for the vast majority of south central 
Texas through 1 am CDT Tuesday. 


Although shear values have decreased slightly from the 50-55 knots 
seen earlier this afternoon in The Hill Country...helicity values 
above 200-300 m^2/s^2 and low LCLs along and east of I-35 will 
likely continue the tornado threat for this area for at least the 
next few hours. Tornadoes will be possible within more discrete 
cells within the line of storms currently centered over the I-35 
Corridor North of San Antonio and expanding into NE Texas and southeast 
OK. Thus...a Tornado Watch continues until 10 PM CDT for the 
eastern Hill Country...and all counties along and north of the 
I-10 corridor and along and east of the I-35 corridor northeast of 
the San Antonio metropolitan. 


Dry air will graciously fill into the entire County Warning Area by early Tuesday 
morning...but another weak shortwave rotating around the 
persistent longwave trough to our west may trigger isolated 
thunderstorms Tuesday afternoon in the serrenias del burro that 
move into the Rio Grande plains. Elsewhere...ample boundary layer 
and soil moisture with daytime temperatures rising into the upper 
80s may still allow for very isolated afternoon showers and 
thunderstorms...but dry air should prevent development. In 
addition...weak shortwave riding should begin to build in by late 
Tuesday night to limit our rain chances. 


Long term (tuesday night through sunday)... 
a brief period of shortwave ridging with relatively dry air will 
continue through early Thursday...giving the region a much needed 
break from the heavy rainfall pattern we have been in for several 
weeks for a few days. However...will still carry isolated 
afternoon showers and thunderstorms for Wednesday due to ample 
boundary layer moisture and soil moisture with highs nearing 90 
degrees. Another upper level trough approaches the region on 
Thursday to break down this ridge...increasing the coverage of 
afternoon showers and thunderstorms...particularly in the Rio 
Grande plains. Models generally agree that the main energy from 
this upper level trough should remain to our north...but also 
suggest that it will not be very progressive and stick around 
until at least Sunday. Considering that a few weak boundaries may 
slip into the region to provide an additional focus for 
convection...rainfall chances will likely continue through Friday 
and the weekend.
