NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
636 PM CDT Thursday may 5 2016 


Aviation... 
/00z tafs/ 
VFR conditions will prevail across area terminals through the 
forecast period. Light and variable winds will dominate the area 
tonight through Friday morning. Later in the period...winds are 
expected to shift to the southeast across south-central Texas as a 
surface high pressure system over the Central Plains pushes to 
the southeast and into southeast Texas coast. It will be a bit 
gusty Friday afternoon across the Rio Grande as pressure gradient 
tightens as a result of a developing surface low pressure system over 
West Texas. 


&& 


Previous discussion... /issued 259 PM CDT Thursday may 5 2016/ 


Short term (tonight through Friday night)... 
wind fields this afternoon have been variable and light...allowing 
surface temperatures to rise a few degrees from yesterday. As high 
surface pressure moves southeast and offshore...surface winds 
should shift to a southeasterly orientation by Friday morning. 
Visible and WV satellite imagery shows some moisture moving into 
the western half of the state and resulting in some high clouds 
over the County Warning Area. 


More of the same expected again tomorrow as the high amplitude 
ridge axis bisects the state. As thicknesses continue to increase 
and winds return to the southeast...temperatures should continue 
their warming trend over the last couple days and warm into the 
middle 80s to lower 90s across the County Warning Area. 


Of some concern is the increased pgf over the far western zones 
tomorrow afternoon during peak heating. Min relative humidity values should 
decrease to the lower 20s by middle afternoon and coupled with winds 
in the 15-20 knots range...could result in an elevated fire weather 
concern. However...fuels continue to stay at or above normal 
moisture levels. 


Long term (saturday through thursday)... 
as the Omega block pattern shifts and evolves into the 
weekend...pop chances increase beginning Saturday evening out west 
and spreading east through Monday. Forecast soundings at kdrt 
Saturday night show capping and minimal cape above 600 mb. Models 
have also been underestimating cap strength along the Rio Grande 
as of late and deep moisture appears to be lacking. However...low level jet 
strength in the GFS shows 50+ kts out of the due south as an 
embedded shortwave disturbance translates northeast into central 
Texas...so included at least slight chance probability of precipitation for these areas 
west Saturday night through Sunday morning. 


Sunday...a dry line develops just west of the western Val Verde 
border with another strong low level jet running parallel to the dry line at 
40-50 kts. Another embedded shortwave is prognosticated to pass north of 
the County Warning Area and develop storms to our north. Forecast soundings this 
time show an uncapped but dry environment at the 
surface...suggesting the dry line may mix in the low levels 
further west and hinder cirrus development on the plateau in our County Warning Area. 
But enough elevated cape and deep layer shear should remain 
present for the potential for strong to severe storms...should 
they develop. 


The next broad shortwave passage on Tuesday night will interact 
with the lesser defined dry line bisecting the County Warning Area. Storm 
possibilities should stay east of i35. While all long range models 
produce quantitative precipitation forecast...the GFS an outlier producing significantly higher 
quantitative precipitation forecast than the ECMWF/Canadian/dgex/UKMET. Left slight chance and low 
end chance probability of precipitation...mostly east...for this time period. Beyond 
Wednesday...only slight chance probability of precipitation in the forecast through the 
rest of the 7 day.
