Severe Weather Alert Descriptions

 Special Statement  Statement as of 2:48 PM CDT on July 22, 2014


... Heat index values near 105 degrees Wednesday afternoon...

High temperatures Wednesday will again range from the mid 90s to
near 100 degrees across the Rio Grande and coastal plains. In
addition... southeasterly winds will continue to provide a supply
of Gulf moisture to the region. The heat and moisture in place
will combine to drive heat index values to around 105 degrees
during the afternoon hours. As temperatures fall around sunset
heat index values should drop below 100 degrees.

Take extra precautions if you work or spend time outside. Wear
light weight and loose fitting clothing when possible and drink
plenty of water. Never leave children... disabled adults or pets in
parked vehicles.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
636 PM CDT Tuesday Jul 22 2014 


Aviation... 
VFR conditions are expected to prevail through the taf period. 
Could see brief MVFR stratus at ksat/kssf in the near dawn hours. 
Surface winds will be southeast-southerly mostly 5 to 10 kts overnight...with a 
slight backing to the southeast-east Wednesday afternoon.

Previous discussion... /issued 338 PM CDT Tuesday Jul 22 2014/ 


Short term (tonight through Wednesday night)... 
the strong upper ridge has put a lid on convection across most of 
Texas this afternoon. We do not expect any showers or thunderstorms 
from now through the night. Look for a repeat on Wednesday for 
most of our area...as the ridge essentially stays in place. 
However...we did add small probability of precipitation for the far eastern coastal plains 
as precipitable water increases (quite substantially in the NAM...less so in the 
gfs) and the sea-breeze may be enough to generate isolated storms. 


Long term (thursday through tuesday)... 
a TUTT-low (or at least an upper-level trough) now over southeast 
Louisiana will move west-southwest and eventually all the way to 
the lower Rio Grande...and beyond. We stayed near the previous 
forecast and kept low probability of precipitation for the plains east of the I-35 
corridor on Thursday. Without a strong surface focus other than 
the sea-breeze...and increasing middle-level capping and lower precipitable water to 
the west...it seems convection will have a hard time moving west. 


Beyond Thursday...the upper level ridge re-configures to a more 
meridional (north-south) orientation...as a deep trough forms over 
the Great Lakes. Despite the orientation change...the ridge will 
still maintain near or above normal temperatures through the 
middle of next week. There are some indications in the GFS/European model (ecmwf) 
for a backdoor cold front to move into East Texas by the middle of 
next week. There is too much uncertainty at this forecast range to 
mention probability of precipitation in the forecast...other than we will be monitoring 
this in coming days.
