Severe Weather Alert Descriptions

 Special Statement  Statement as of 3:46 PM CDT on July 25, 2014


... Heat index values around 105 degrees this weekend...

The combination of warm temperatures and high dewpoints will
produce heat indices ranging from 103 to 107 degrees during the
afternoon hours this weekend. The most likely locations to
experience these heat indicies will be along and south of a
Lexington to San Antonio to Eagle Pass line.

Take extra precautions if you work or spend time outside. Wear
light weight and loose fitting clothing when possible. Drink plenty
of water and take frequent breaks from the heat. Young children...
disabled adults and pets should never be left unattended in
vehicles under any circumstances. This is especially true during
warm or hot weather when car interiors can reach lethal
temperatures in a matter of minutes.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
331 PM CDT Friday Jul 25 2014 


Short term (tonight through Saturday night)... 
recent mesoscale model runs still show hints of convection over 
the southern Rio Grande plains this afternoon into early 
evening...but chances are low so we only kept isolated early 
evening wording in the text forecasts. Any storms that develop 
should dissipate by 02z. Otherwise...the upper level ridge builds 
east across Texas and northwest across The Rockies...so expect hot 
and dry conditions on Saturday. 


&& 


Long term (sunday through friday)... 
the upper level ridge maintains a strong influence across Texas 
through Tuesday. Height/thickness values support slightly above 
normal temperatures. The combination of heat and increasing dew 
point will produce heat index values of 100-107 for a few hours 
each afternoon across the coastal plains. We will highlight this 
in the severe weather potential statement and issue an Special Weather Statement...but in reality it/S really not much 
hotter than typical conditions for late July. 


A deep upper level trough over the Great Lakes...the ridge over 
The Rockies...and a trough along the Pacific coast will form an 
Omega blocking pattern next week. This will result in an unseasonably 
cool air mass for the eastern half of the country...including Texas. 
Medium range models have been consistent in pushing a main cold 
front and potentially minor outflow boundaries through most of 
Texas. Isentropic lift and moist air pooling along these 
boundaries (pw approaching 2.4 inches) will create an favorable 
environment for at least scattered storm coverage...and potentially 
heavy rain. Extensive cloudcover and rain may keep high 
temperatures well below normal. Due to uncertainty in specific 
placement of features...we will start the trend to increase probability of precipitation 
and quantitative precipitation forecast...and decrease high temperatures...for Thursday and Friday. 
Expect additional adjustments as model guidance and observations 
clarify expectations.
