NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1155 PM CST sun Dec 21 2014 


Update...06z aviation below. 


&& 


Aviation...at 05z IFR ceilings prevailed along and southwest of 
a erv-Sat-vct line. Exception was sky clear out at drt...but this 
should fill in over the next hour or two. Northeast of this line 
MVFR ceilings prevailed. Shallow moisture will remain trapped 
beneath inversion overnight...with saturation and cloud deck 
lowering early in the morning. Looking more likely for mix of 
IFR/LIFR conditions across southern and western areas...and 
continued to indicate this at Sat/ssf/drt. In addition...patchy 
-dz occuring overnight along the I-35 corridor. Westerly low 
level flow will develop along the I-35 corridor 15z-18z with 
passage of low level trough...with northwest flow over the Rio 
Grande and Hill Country. This should result in better mixing and 
clearing along and west of I-35 middle to late morning...and 
eventually VFR conditions at all taf sites. 


&& 


Previous discussion... /issued 1131 PM CST sun Dec 21 2014/ 


Update... 
updated to include drizzle mention through 09z for i35 corridor 
and east due to latest observation. Fog is beginning to set in along the 
southern Rio Grande Valley and up to the southern periphery of the 
Escarpment. This is on track with the evolution depicted in the 
models so confidence has increased in the current forecast. 


High clouds are moving in from the northwest in addition to the 
low ceiling development spreading back west towards kdrt. Seeing 
winds just north of the County Warning Area at 15-20 miles per hour sustained with gusts up 
to 25 miles per hour in response to a tightening pressure gradient. For 
now...the forecast still looks pretty good for the winds but if 
they continue to increase...may need to update again to account 
for this.

Previous discussion... /issued 737 PM CST sun Dec 21 2014/ 


Update... 
latest infrared satellite shows low level cloud deck deteriorating west 
of i35 corridor. Kdrt showing some light fog already at 01z. 
Both RUC and hrrr indicate zero degree dewpoint depressions along 
the Rio Grande up to kdrt and up onto the Escarpment beginning 
around 06z. With a tightening surface gradient over our west and 
resultant winds in the 10-15 miles per hour range already...dont think fog 
will be able to set in on the Escarpment much...however included 
areas of fog along the Rio Grande Valley and south of the 
Escarpment by 09z. Also updated sky grids...hourly T...and hourly 
dew T grids to capture latest trends. 


Previous discussion... /issued 339 PM CST sun Dec 21 2014/ 


Short term (tonight through Monday night)... 
clearing has been very stubborn this afternoon but areas out west 
and southwest are finally starting to show some sunshine. Upper 
trough axis is over the state right now with more cloudiness and 
moisture upstream over The Rockies. Most areas will cloud back up 
overnight and have mentioned some patchy fog over southern areas. 
Areas that clear this evening will have a better chance of getting 
the fog. Low and middle level wind fields will have a westerly 
component on Monday meaning warmer temperatures and more sunshine. 
Most areas should reach into the 70s. Should be a very pleasant 
day. Although we lose the low clouds tomorrow night we will still 
have some middle and high clouds around with the upstream system over 
The Rockies. Lows Monday night expected to be in the 40s to low 
50s. 


Long term (tuesday through sunday)... 
will see a cold front push through the County Warning Area early Tuesday morning while a 
deep trough develops over the central and Southern Plains. An upper 
wave will push southeast out of The Rockies on Tuesday with some of its 
energy staying over south central Texas early Wednesday. With the cold 
front and upper level troffing...looks like Tuesday will be mostly 
cloudy and cooler. 700 mb trough axis shifts east late Tuesday night 
which should mean a clearing pattern on Wednesday although temperatures will 
remain cool as the surface high remains over West Texas and The 
Rockies. The upper pattern flattens as Texas is at the base of a 
long wave troffing pattern across most of the country by middle week. 
Moisture levels will remain low for Thursday and Friday which will 
translate to mostly sunny skies...cool/cold nights...and cool 
afternoon highs in the 60s. Will see a return of morning lows in 
the 30s middle to the end of the week. Another cold front is 
forecast for Friday but should come through dry as there will be 
little to no moisture to work with.
