NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
626 am CDT Thursday Aug 21 2014 


Aviation... 
the I-35 taf sites have been alternating between VFR and MVFR this 
morning due to patchy stratus across south central Texas. Expect 
the status to stick around through 15z causing periods of MVFR 
ceilings along the I-35 terminals. Del Rio could also see periods of MVFR 
ceilings...similar to the last two mornings...so have continued to 
carry the tempo group from 13 to 15z. VFR conditions this 
afternoon under partly cloudy to mostly sunny skies. Stratus will 
once again develop tonight...building over the I-35 terminals 
between 07z/08z and at drt around 11z Friday morning then burning 
off by 16z. 


Winds will continue to be strong and gusty today out of the south 
(aus/Sat/ssf) and southeast (drt). The highest wind speeds are 
expected to be this afternoon when we could see sustained winds 
between 10-15 knots and gusts as high as 25 knots. Winds weaken to 
around 10 knots tonight.

Previous discussion... /issued 342 am CDT Thursday Aug 21 2014/ 


Short term (today through friday)... 
a couple of weak showers continue from storms that moved into the 
western zones late this evening. These should continue to weaken 
as they progress north over the next few hours. Otherwise...today 
will be hot and dry for much of south central Texas. Cant 
completely rule out a stray shower this afternoon but moisture 
levels are too low to warrant any mention of activity in the 
official forecast at this time. Precipitable water values remain around 1.5 
inches or less on Friday and will keep the forecast dry. The 
drying of the atmosphere is in response to a building high moving 
in from the east. The subsequent subsidence is therefore drying 
out the atmosphere and ending rain chances for the area. Low-level 
thermal profiles are not expected to change too much and high 
temperatures should be persistent...around the middle 90s to near 
100 degrees. 


Long term (friday night through wednesday)... 
the upper high is forecast to weaken and lift north by Sunday. 
This is in response to a low pressure system moving into the 
northern plains. This should allow moisture values to slowly 
increase again with afternoon shower and thunderstorm activity 
returning to the forecast on Wednesday. The return of precipitation could 
be a bit sooner than that depending on the rate of the moisture 
return...but opted to leave the forecast dry until Wednesday for 
now. Just beyond the current package...the GFS is forecasting a 
fairly progressive trough moving through the plains Thursday which 
would send a frontal boundary into Texas Thursday/Friday bringing 
rain chances for much of the forecast area. The European model (ecmwf) is much 
slower with its handling of the upper trough and keeps high 
pressure persistent over the Southern Plains. The more progressive 
pattern of the the operational GFS is supported by most of the 
gfsensemble members as well as the Canadian so it does bear 
watching.
