NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
253 am CDT Thu Sep 29 2016 


Short term (today through friday)... 
cold front passage progged for 14-15z for aus this morning should 
shift winds to the north and re-enforce the dry atmosphere in 
place over the region. While guidance values are not too gung-Ho 
about surface wind fields. There is some potential for 15-20 kt 
winds to mix down to the surface from indication in the rap 
sounding analysis. Have notched up winds in the grids just a bit 
over superblend for this possibility. 


Otherwise, biggest news in the short term will be how pleasant 
Friday will be. Morning lows should fall to the low 50s and would 
not be surprised to see upper 40s in a couple of low lying areas 
such as river channels or valleys. Euro ensembles are showing some 
members in the upper 40s for Kerrville/Fredericksburg and the 
surrounding Hill Country, even Austin Bergstrom. While the 
radiational cooling set up will be peachy, think the likelihood of 
any place getting 40s will be best in The Hill Country. 


&& 


Long term (friday night through wednesday)... 
the weekend will shape up to be quite nice as well with morning 
lows in the 50s and highs in the upper 70s and low 80s Saturday. 
Gradual warming trend will begin Sunday as highs reach back into 
80s throughout the County Warning Area. 500 mb ridging will set up through the 
beginning of next week but will be short lived as another closed 
low from the Pacific northwest pushes east through the Rocky 
Mountain range. 


By Wednesday morning, both GFS and European model (ecmwf) are indicating a cold 
front being pushed into the state from the northwest. While 
considerable differences exist in synoptic pattern, namely 
negative tilting (ecmwf) vs positive tilting (gfs), both are 
indicating a possible mesoscale convective system passage with this next frontal system 
Wednesday. Since considerable uncertainty in details exist, only 
opted to go with slight chance pops for day 7 for now. But for 
now, no hazardous weather inclusion was made to the forecast.
