NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
615 am CDT Sat Aug 23 2014 


Aviation... 
areas of stratus with MVFR ceilings east of kcot to kuva to kaqo line 
will dissipate by middle morning leaving VFR skies with few VFR level 
cumulus and cirrus late morning through evening. Areas of stratus 
with MVFR ceilings will redevelop overnight mainly east of kcot to kuva 
to kaqo line and then dissipate by middle morning Sunday with VFR 
skies by midday. S to southeast winds will increase to 10 to 15 kts late 
morning through evening with gusts to 22 kts possible. Winds will 
decrease to 7 kts or less tonight before increasing again Sunday.

Previous discussion... /issued 328 am CDT Sat Aug 23 2014/ 


Short term (today through sunday)... 
south central Texas remains on the periphery of a high pressure 
currently centered over the southeast United States. The high 
pressure will keep the area dry and hot through the weekend. With 
no chances of precipitation the main weather story is the heat. 
The good news is that across our western counties heat index 
values will remain below 100. That is not the case across the 
coastal plains. With dewpoints in the upper 60s to near 70 we 
expect another day of heat index values above 105 along and south 
of a line from Floresville to Gonzales to La Grange. Have elected 
to keep the heat advisory through 7 PM this evening for this area. 
Those out and about enjoying the last weekend before school starts 
on Monday should be aware of the high heat index values and take 
appropriate precautions to avoid heat exhaustion. Elevated fire 
weather conditions are expected along the Rio Grande plains this 
afternoon and evening. 


Long term (sunday night through friday)... 
the ridge continues to be the main weather feature for the start 
of the work week. Partly cloudy to mostly sunny skies and mostly dry 
conditions can be expected for the first half of the week. Having 
pushed off to the north and east the ridge will have less of a 
grip on our temperatures. While temperatures will still be above 
seasonal normals they should be a degree or two cooler. 


A major change in the weather comes middle week. First models show a 
weak shear axis moving along the Texas coast Tuesday and 
Wednesday. This will act to enhance the sea breeze shower and 
thunderstorm activity these two days. Middle Range models then show 
an upper trough moving into the Central Plains on Wednesday. A 
weak cold front will accompany the trough and stall across North 
Texas on Thursday. This front looks similar to the other fronts we 
have seen across central Texas this Summer. Most of our 
precipitation with this trough/front will come from remnant 
outflow boundaries left over from convection to our north closer 
to the front. The best chances for precipitation and best lift look 
to be Thursday afternoon through Friday as what is left of the 
front pushes through our area. Because the front will be weak with 
the main trough pushing off into the Ohio Valley will continue 
only slight chance probability of precipitation for now. While this front will not have a 
significant impact on temperatures it will drop them a few degrees 
closer to our normal temperatures for this time of year.
