NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
701 PM CDT Sat Jul 23 2016 


Aviation... /00z tafs/ 


Aviation forecasts should follow persistence trends for one more 
day before a pattern change develops Sunday night. A few hours of 
MVFR cigs and perhaps a brief dip into IFR cigs are expected again 
as nighttime winds stay generally below 10 knots. Light to 
moderate late morning winds and drier air in the mid levels of the 
atmosphere should continue to lead to rapid mixing to VFR skies by 
around 15z. Isolated convection could impact approaches to the 
aus/Sat/ssf terminals from the distant east Sunday afternoon, 
with no impacts expected in the vcnty of these sites.

Previous discussion... /issued 303 PM CDT Sat Jul 23 2016/ 


Short term (tonight through Sunday night)... 
another warm night is in store across the area as low level moisture 
increases overnight. Dewpoint temperatures in the lower to mid 
70s are forecast to spread across the eastern two-thirds of 
south-central Texas through the period. Will start with broken to 
overcast skies on Sunday morning with clouds scattering out during 
the late morning hours. Sunday's high temperatures are expected 
to reach the upper 90s to 100 across much of the area and up to 
104 along the Rio Grande. Heat indices are expected to reach the 
102 to 111 mark east of Interstate 35 for several hours in the 
afternoon (1 PM to 6 pm). A Special Weather Statement is likely to 
be issued later on to give emphasis on these elevated values. 
Also, there is a slight chance of rain across the coastal plains 
Sunday afternoon as sea-breeze shower and thunderstorm activity 
pushes further inland. 


Long term (monday through saturday)... 
big changes are on the way for the first part of the week. As the 
subtropical ridge pushes farther to the west and into The Four 
Corners region, rain chances will be increasing across the area. 
Medium-range models are suggesting the development of an upper 
level short-wave dropping from the northern plains into the Ohio 
Valley late Monday into Tuesday. Convection along the short-wave 
axis is expected to push to the southwest along the periphery of 
the subtropical ridge. At the surface, remnant of a cold front 
pushing across the Southern Plains in combination with a moist 
southern flow will aid showers and storms to form and affect most 
of south central Texas, especially Tuesday. Also, an inverted 
upper level trough is forecast to move across the northern part of 
the Gulf of Mexico into the Texas coast. This will bring pwats of 
2 to 2.19 inches (per area forecast sounding of GFS model). With 
these values in place, we are expecting rainfall accumulations of 
one tenth to one quarter inch with isolated spots of 2 to 3 
inches. Weather conditions will improve Tuesday evening into 
Wednesday with dry conditions expected for the latter part of the 
week. 


We will have a break from the upper 90s and 100 degrees days 
seeing the past several days early next week due to increase in 
cloud coverage and rain chances. However, this cool episode is 
short-lived as dry and hot weather conditions return later in the 
week into next weekend.
