NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
453 PM CST Wed Dec 7 2016 


Aviation... 
low MVFR ceilings are expected to continue for the next 24 hours 
as colder air filters into the region. There could be some IFR at 
times, but will not mention it at this time. Winds will begin to 
increase and become breezy after midnight as the main front makes 
it to the region. Should see speeds around 15-20 knots with higher 
gusts. The winds should diminish around sunset tomorrow. 


&& 


Previous discussion... /issued 235 PM CST Wed Dec 7 2016/ 


Short term (tonight through Thursday night)... 
a few weak echos starting to show up on radar this afternoon 
across the southeastern counties. Isolated showers will be 
possible through this area for the remainder of the afternoon and 
tonight ahead of the front. The cold front is still on track to 
enter the northern County Warning Area after midnight and clear the southern County Warning Area 
before daybreak. 


Colder behind the front and windy throughout the day on Thursday. 
Funneling of winds along the edge of the Escarpment will lead to 
the strongest winds along and just east of the I-35 corridor, 
where gusts of 30-40 mph will be possible. This will prompt a Wind 
Advisory for this region. Temperatures on Thursday likely not to 
make it out of the upper 30s across The Hill Country and low to 
mid 40s elsewhere. Combined with the winds, wind chill values will 
be in the mid to upper 20s across The Hill Country and 30s 
elsewhere during the day on Thursday. 


Models continue to indicate some light quantitative precipitation forecast being generated well 
behind the front on Thursday across west central Texas into 
central Texas, clipping the far northern County Warning Area. This appears to be 
is association with ascent near the right entrance region of an 
upper level jet streak. In the cloud layer temperatures are 
supportive of ice introduction. However forecast models have come 
in warmer with the warm nose between 800-700mb, beneath the cloud 
base, but also drier. This could result in wet bulbing but should 
remain just warm enough to support a light rain or light sleet mix 
using the top down approach. A slight chance of rain/sleet mix 
remains in the forecast mainly north of a Fredericksburg to 
Georgetown line. We anticipate ground temperatures, including 
elevated structures, to remain just above freezing and combined 
with the light quantitative precipitation forecast amounts do not expect any significant impacts. 


Models have trended slightly stronger with the winds staying up 
Friday night near and east of I-35, and also a deg or two warmer 
on the overnight temps. We are still expected a widespread freeze 
across The Hill Country Thursday night/Friday morning in the mid 
20s, with freezing temps of 9-12 hours in this region. Along the 
I-35 corridor and east, north of I-10, lows in the upper 20s to 
low 30s are expected with a freeze likely in the Austin Metro area 
but less certain now in San Antonio. Temps farther south and along 
the Rio Grande are forecast to remain just above freezing. 


Wind chill values Thursday night into Friday morning will dip into 
the upper teens across The Hill Country and 20s elsewhere. 


Long term (friday through wednesday)... 
continued cold temperatures on Friday with highs only in the 40s, 
but much less wind and partially clearing skies should make it 
feel warmer compared to Thursday. A return flow will set-up 
Saturday and Sunday with gradually modifying temperatures. Some 
slight chances for showers across the central and eastern 
counties over the weekend. Models are still indicating another 
front on Sunday evening.
