NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
643 am CDT Monday Aug 29 2016 


Aviation... /12z tafs/ 


Low to mid level cyclonic winds have picked up early this morning 
as a low pressure system drifts southwest along the Texas coast. This 
has altered prevailing wind directions, but most winds are 
expected to remain below 12 knots. Scattered showers generally 
east of Hwy 281 have picked up speed to around 15 mph so the 
influence over I-35 terminals has shifted forward for early in the 
forecast period. Some IFR cigs is adjacent to the showers near 
aus, but slightly higher cigs in the MVFR category are expected 
around San Antonio. Most of the heavier downpours and possible 
thunderstorms are expected to be brief so will keep vsch around 
Sat/ssf while slightly higher pwat values near aus could support 
more deep convection. Out west, drt is expected to see late 
morning showers from a West Texas/nrn Mexico disturbance. VFR skies 
are projected for much of this afternoon and evening, but 
increased stability and cigs down to IFR are expected to form 
after midnight over I-35 taf sites.

Previous discussion... /issued 343 am CDT Monday Aug 29 2016/ 


Short term (today through tuesday)... 
an upper level low meandering over the northwestern Gulf of Mexico 
and Texas coastal areas will bring slightly above normal moisture 
to south central Texas today through Tuesday. Daytime heating will 
be the main forcing mechanism with outflow boundaries maintaining 
them into the evening. Expect showers and thunderstorms to develop 
in the morning, become scattered in the afternoon, and dissipate 
by late evening. Locally heavy rains are possible due to the above 
normal moisture (pws of 1.8 to 2.2 inches) and expected slow storm 
motions. Wind gusts up to around 30 mph are possible near the 
stronger storms due to moderate dcape. 


Long term (tuesday night through sunday)... 
upper level low rapidly dissipates Wednesday with weak ridging at 
the surface and aloft over south central Texas through the Labor 
Day weekend. Decreasing moisture levels leads to only isolated 
daytime showers and thunderstorms. Tropical depression 9, possible 
storm is not expected to have an impact on south central Texas as 
its forecast track is across the northern part of the Florida 
Peninsula. However, a weak front possibly drifting into central 
Texas may continue the isolated showers and thunderstorms this 
weekend.
