NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1258 PM CDT Sat Apr 19 2014 


Aviation... 
all sites are currently VFR although middle and high cloudcover 
continues to stream over the area from the southwest. Precipitation on 
the kdfx radar is staying off to their west as of right now. Pop 
is too low to include in the drt taf for the afternoon and evening 
hours. If organized convection can form over Mexico...may be able to 
input a tempo group with some impact at the drt taf site. All 
sites were left with no mention of precipitation in the tafs. 


All MOS guidance and simulated WRF satellite show IFR conditions 
developing late tonight around that 07-09z time frame...advancing 
in from the southeast. Went with these lower ceilings in the forecast and 
mentioned IFR all locations developing prior to or around dawn. 
NAM was very robust in keeping low ceilings all day on Sunday...unlikely 
given the time of year and partial heating expected on Sunday. No 
doubt looks to be plenty of moisture in a few layers across the 
area and went MVFR at least through all the morning hours. More 
optimistic with some VFR by early afternoon as moisture mixes just 
a bit. Will watch convection chances out west near drt once 
again...later forecasts may have to input a prob30 grouping for 
Sunday afternoon ts possibilities.

Previous discussion... /issued 1022 am CDT Sat Apr 19 2014/ 


Update... 
first period forecast is on track with expected weather conditions 
through this afternoon. Isolated showers and couple of thunderstorms 
are possible through this afternoon mainly across Val Verde County 
as a short-wave disturbance/vorticity maximum moves over southwest 
Texas. Still expecting a larger coverage of convection for this 
evening across the southern Rio Grande plains and Edwards Plateau 
as a second but stronger upper level short-wave disturbance pushes 
to the northeast and over central Texas. Activity should diminish 
significantly at or after midnight tonight/early Sunday. Rainfall 
amounts will generally be light or from a trace to few hundredths 
of an inch. 


Previous discussion... /issued 651 am CDT Sat Apr 19 2014/ 


Update... 
showers appear to be ahead of schedule...so just updated the 
forecast to have probability of precipitation all day for the northern Rio Grande plains. 
Still expecting spotty coverage and light quantitative precipitation forecast amounts. 


Previous discussion... /issued 350 am CDT Sat Apr 19 2014/ 


Short term (today through sunday)... 
the main changes in atmosphere over the next 48 hours will be 
increasing moist Gulf flow at low levels...and Pacific moist air 
at middle and upper levels...as a ragged upper low moves from Southern 
California into the Southern Plains. Smaller vorticity centers 
will rotate through the larger circulation...with one timed early 
this morning...and the second for late tonight. The first will not 
impact our area...but the second will affect the Rio Grande 
plains...where low probability of precipitation were added for an overnight weak mesoscale convective system or 
cluster of storms that will originate on the Mexican mountains 
during the late afternoon before moving east. 


Another piece of vorticity and the approach of a jet streak/S left 
exit region should be enough for probability of precipitation across the entire area on 
Sunday. The best chance again will be across the Rio Grande 
plains...where there will also be the possibility of severe 
storms with the main threats of large hail and damaging winds. 
Overall...quantitative precipitation forecast will be spotty and generally light today and 
Sunday.
