NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1237 PM CDT Friday Sep 4 2015 


Aviation... 
ceilings have climbed to VFR in Austin and San Antonio and these 
clouds will linger through the afternoon. There is a slight chance 
that a shower or thunderstorm could pass over one of the 
airports...but this is not likely. Overnight we should see a 
repeat of this morning with MVFR ceilings developing and then 
improving late morning Saturday. 


At drt conditions will be VFR through the afternoon and evening. 
MVFR ceilings will make out there Saturday morning for a few hours.

Previous discussion... /issued 407 am CDT Friday Sep 4 2015/ 


Short term (today through saturday)... 
water vapor images are showing an upper level high pressure 
system extending from NE Texas southwestward to NE Mexico. 
Also...a middle to upper level inverted trough across the eastern 
part of south central Texas is being depicted. Both hires and 
medium-range models have this feature moving to the west today 
while moisture escalates. Precipitable waters  are forecast to increase late this 
afternoon (southeast counties) to about 2 inches. With that in 
mind and the lift provided by the middle level trough...expect 
isolated heavy showers across the coastal plains and south of a 
Kenedy to Schulenburg line. Rainfall amounts would generally by 
around few hundredths to one quarter inch with isolated spots of 1 
to 2 inches. Rest of the area should remain dry...but cant rule 
out an isolated shower or storm during the afternoon period. Partly 
cloudy skies will prevail for the afternoon hours with highs in 
the lower 90s across The Hill Country to upper 90s across the 
southern Rio Grande. Overnight lows are forecast to be around the 
low to middle 70s most areas. 


Isolated showers or storms are expected Saturday afternoon across 
the southeast counties...otherwise...partly cloudy skies and 
warmer temperatures with highs in the middle 90s across The Hill 
Country to 101 across southern Rio Grande. 


Long term (saturday night through thursday)... 
an upper level high pressure across central Texas will dominate 
from Sunday into the middle of next week. However...cant rule out 
few storms affecting the coastal plains and parts of the southeast 
counties each afternoon Monday through Wednesday. By 
Thursday...the upper level high pushes southwest into central 
Mexico and weakens while an upper short-wave trough swings across 
the northern plains into the Great Lakes. A cold front associated 
with the upper short-wave is forecast to approach the area late 
Thursday into Friday. Ecm and GFS are not in good agreement with 
the timing and passage of the boundary across our area. For this 
package...opted to do a model blend. However...if GFS verifies 
(wettest model per latest run)...some areas may get several 
inches of rain. Stay tuned.
