Severe Weather Alert Descriptions

 Flash Flood Watch  Statement as of 12:52 PM CDT on May 27, 2015


... Flash Flood Watch in effect from 7 PM CDT this evening through
Thursday morning...

The National Weather Service in Austin/San Antonio has issued a

* Flash Flood Watch for a portion of south central Texas...
including the following areas... Bastrop... blanco... Burnet...
Caldwell... Gillespie... Hays... Lee... Llano... Travis and
Williamson.

* From 7 PM CDT this evening through Thursday morning

* showers and thunderstorms capable of producing locally heavy
rainfall are expected to develop and move across The Hill
Country and parts of Interstate 35 (including the Austin Metro
area). Rainfall totals of one quarter to half inch are
expected... with isolated amounts up to 2 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 rain develops. Many rivers
and streams remain out of banks or in flood. Additional rainfall
will extend the time at or near crest levels and delay the
recession.

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.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
618 PM CDT Wednesday may 27 2015 


Aviation... 
VFR conditions prevail with breezy southerly flow. Overall chances 
of convection are too low to mention in the current taf package 
but may need to be introduced at a later time. MVFR...then IFR 
ceilings are expected tonight before lifting back to VFR by early 
tomorrow afternoon. 


&& 


Previous discussion... /issued 305 PM CDT Wednesday may 27 2015/ 


Short term (tonight through Thursday night)... 
visible satellite images are showing several outflow boundaries 
across the region including the one that helped storms to fire up 
across blanco and Travis counties middle morning. There are still 
few thunderstorms on going across western Llano County as they 
slowly push to the north. This activity may come to an end within 
the next few hours. However...later this evening...a line or 
complex of storms are expected to develop along outflow boundaries 
pushing west across central Texas...ahead of a dry-line over West 
Texas and north of the remnant of this morning surface/outflow 
boundary. At this time...some hires models and the 12z GFS 
solution continue to indicate convective initiation across central 
Texas and pushing across the northern Hill Country for this 
evening. Latest hrrr is showing convection north of Burnet and 
Llano counties early this evening but dissipate activity around 8 
or 9 PM. Latest ecm solution is not showing precipitation across our area 
through the first period. With all of these disagreements in 
place...we decided to go with the more aggressive solutions which 
shows showers and thunderstorms affecting the northern part of 
south central Texas tonight. Also...a Flash Flood Watch is in 
effect across The Hill Country from 7 PM this evening through 7 am 
Thursday. This decision has been made based on going flood issues 
across the area and the little amounts of rainfall that will take 
for areas to flood in a short period of time. As a reminder...we 
have a low confidence on tonight's rain due to poor agreement 
between models. 


For Thursday night into Friday...our confidence increase as 
models agree on bringing a line of strong to severe storms across 
the Edwards Plateau and Rio Grande plains. Heavy rain is likely 
and flash flooding is possible mainly across area 
roads...underpasses...poor drainage areas...and small creeks. A 
Flash Flood Watch could be issued for areas west of Highway 83 
later tonight or Thursday. 


Long term (friday through wednesday)... 
showers and thunderstorms will continue across south central Texas 
through the upcoming weekend with a drier trend expected for next 
week. The subtropical ridge will build across The Four Corners 
region and bring drier and warmer days for much of next week.
