National Weather Service Austin/San Antonio Texas

VFR conditions will continue at all terminals through the taf 
period with light and variable winds overnight becoming southerly 
between 6 to 8 knots tomorrow.

Aviation... 
/00z tafs/ 
VFR conditions will prevail across area sites through the 
period. Light and variable winds through Saturday afternoon. 


Previous discussion... /issued 300 PM CDT Friday Oct 24 2014/ 


Short term (tonight through Saturday night)... 
the upper ridge axis over Texas will lead to highs well above normal 
this weekend with a few 90 degree readings expected Saturday. With 
light winds over the area...ground and vegetation moisture is 
holding up dew points a few extra degrees...especially in the 
morning hours. The moisture will help minimize cooling under 
mostly clear skies the next couple nights...with mins expected to 
remain slightly above normals. 


Long term (sunday through friday)... 
southerly surface winds return Sunday but should continue to 
decouple at night. Thus we adjusted the moisture return downward 
slightly Sunday as daytime mixing should reduce the accumulated 
low level moisture through Monday. By Tuesday...moisture depth 
should increase sufficiently to produce a more significant area of 
morning cloudiness and thus help to offset afternoon heating by a 
few degrees. A broad troughing feature expected in the middle of 
next week continues to show a delayed frontal timing with each 
subsequent model run...and the 12z runs now suggest the front will 
not make significant progress through south central Texas until 
Wednesday night or Thursday morning. The GFS continues to suggest 
a weak frontal feature to stall over north central Texas Tuesday to 
enable a slight chance of rain over central Texas Tuesday night into 
Wednesday. Will continue to Show Low rain chances Tuesday night into 
daytime Thursday with timing uncertainties and limited moisture 
availability providing reason to cap the chances at 20 percent.
