NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
720 PM CST Friday Dec 19 2014 


Update...overcast cloud deck across the northern County Warning Area has expanded 
south this evening...along and east of U.S. 281. There may be 
additional expansion to the southwest overnight. Minor updates 
made to sky grids to reflect current 11-3.9u satellite trends as 
well as output from the WRF abi synthetic 10.35-3.9u imagery. 
Minor adjustments also made to hourly T grids. Rest of forecast 
remains on track.

Previous discussion... /issued 542 PM CST Friday Dec 19 2014/ 


Aviation... /update for 00z tafs/ 
a deck of MVFR ceilings covers Austin early this evening...and should 
expand southwest to impact Sat/ssf terminals in the next 2-3 
hours. A light but steady nearly wind overnight should keep most 
areas from seeing significant visibility restrictions...but ceilings are 
likely to gradually fall to borderline LIFR/IFR levels toward 
daybreak. Gentle surface ridging continues to be overrun by zonal 
winds aloft through Saturday...so models are trending toward 
overcast skies in the MVFR category all day into Saturday evening. 


Previous discussion... /issued 346 PM CST Friday Dec 19 2014/ 


Short term (tonight through Saturday night)... 
as of 3 PM...skies were beginning to clear up on the Escarpment 
and Rio Grande Valley. Temperatures were able to reach the middle 60s 
in that area with the i35 corridor still only in the upper 50s 
with cloud cover persistent. Believe this gradual sky cover trend 
will play a role in overnight lows and fog potential in the 
morning tomorrow. 


A light northerly wind and cloud cover off the Escarpment will 
probably be enough to inhibit much in the way of fog. However from 
the i35 corridor west...decent radiational cooling and T over 
values of -2 to -6 were indicated in MOS guidance. 
Therefore...included patchy fog for these locations. 


Long term (sunday through friday)... 
a series of cold frontal passages between now and next weekend 
will be the focus for the long term periods. Our first of which 
will be Monday night into Tuesday morning. While this cold front 
is prognosticated to be a quick one...it looks like it will be passing 
through too dry of an air mass set up across the southern half of 
the state. The dry conditions Tuesday night and high surface pressure 
in place will make next Wednesday morning the coldest of the week 
most likely. Opted to decrease the lows a couple degrees for this 
period due to pretty significant ensemble variation lending to the 
idea that the guidance values may not be too accurate. But with a 
surface high pressure center over the Rio Grande Valley keeping winds 
at a northerly component...strong northerly 850 mb winds...and a 
dry column...would imagine the colder side of the fence is the 
best way to lean for Wednesday morning. 


Christmas day is shaping up to look quite pleasant...unless you 
were hoping for cold and snowy. It should begin rather 
chilly...lows in the middle to upper 30s...but certainly not snowy. 
In fact...clear skies and weak ridging should allow highs to reach 
the 70s in some locations. 


The next frontal passage has been slower to arrive with each model 
run the last couple days. While the GFS would have the front 
through our area by Saturday...the Euro doesnt have it clearing 
ewx until Tuesday morning. The upper level patterns of both models 
begin significant Christmas day on handling the next possible 
upper level system so it is unclear which outcome holds more 
water at this point.
