NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1009 PM CDT Sat Jun 25 2016 


Update... 
an outflow boundary has produced a line of thunderstorms mainly 
over Mexico extending south from lake Amistad. Some storms have 
moved into Val Verde County and weakened. This should continue for 
a few hours and have updated the forecast to reflect an increased 
chance for thunderstorms there. The rest of the area looks fine. 
Have also adjusted temperatures out west where rain has cooled 
things off more rapidly than we previously anticipated.

Previous discussion... /issued 634 PM CDT Sat Jun 25 2016/ 


Aviation.../00z update/ 
convection is currently most active across the western portions of 
the area while central and east are seeing areas of light rain and 
isolated rain showers. Expect the convection to end near or 
shortly after sunset. Low clouds begin to develop 07z across the 
east and I-35 corridor with MVFR cigs. Low clouds will develop 
west and will cause MVFR cigs at kdrt around 11z. Have included a 
brief period of IFR cigs at kaus and could see an hour or two at 
ksat/kssf but did not include in this forecast. Winds will be east/southeast 
near 10 knots across the east becoming southerly at 5-10 knots 
after 06z. Kdrt will see east/southeast winds 10-20 knots for first few 
hours of the forecast then decreasing to near 12 knots. After 15z- 
16z Sunday cigs begin to lift and will become VFR after 18z. Winds 
will become southeast 10-15 knots across the east after 15z and southeast 15-25 
knots at kdrt after 15z. Isolated convection expected across the 
eastern areas on Sunday and scattered along the Rio Grande. Did 
include vcsh after 16z for kdrt and later forecast may include 
thunderstorms in the vicinity based on trends. 


Previous discussion... /issued 307 PM CDT Sat Jun 25 2016/ 


Short term (tonight through Sunday night)... 
south central Texas is sandwiched between a compact ridge of high 
pressure over Louisiana and a weak upper level disturbance/TUTT 
low in northern coahuila that is slowly pushing north into The Big 
Bend region. This has caused a surge in precipitable water values in excess of 
2 inches along and east of the I-35 corridor, which coupled with 
weak dynamic forcing from the upper low and a weaker midlevel 
inversion, has led to scattered showers and thunderstorms in the 
coastal plains and I-35 corridor. Rainfall amounts are still 
expected to average in the 0.25-0.5 inch range with very isolated 
totals of 1-2 inches that receive multiple bouts of heavy rain. A 
stronger midlevel inversion out in the Rio Grande plains and 
Edwards Plateau is expected to hold for at least a few more hours, 
but some deeper convective cells are still expected out there 
during the late afternoon and evening hours. Storm coverage should 
decrease appreciably by the early evening hours elsewhere. 


Most models continue to take the upper level low slowly into West 
Texas, although a few models (most notably the nam) do keep the 
low fairly stationary around the Edwards Plateau region tomorrow. 
Nevertheless, all models continue to shear the low significantly as 
it becomes and open inverted trough. Thus, dynamic forcing 
provided by this dissipating TUTT low will be much weaker tomorrow 
to allow the upper level ridge over Louisiana to expand and 
reassert itself over East Texas. Therefore, storm coverage is 
expected to be much lower tomorrow with just isolated showers and 
thunderstorms across most of the region. The greatest chances will 
be in the Rio Grande plains where dynamic forcing is greatest and 
in the coastal plains where some isolated showers beneath a 
strengthening midlevel cap may form. However, most spots will not 
receive any rainfall and convection should be shallower in the 
coastal plains and I-35 corridor than today so thunderstorms in 
these areas should be very isolated. 


Long term (monday through saturday)... 
the upper level ridge should continue to slide to the west and be 
centered more over Texas on Monday to limit rain chances over most 
of the region. This ridge will indirectly merge with a building 
ridge over The Four Corners region by Tuesday which will help 
amplify a quick moving trough over the eastern half of the country 
that will drag a weak back door cold front into northeast Texas. 
Showers and thunderstorms forming along this front may move into 
the northeastern parts of south central Texas on Tuesday. Better 
rain chances for most of the region will most likely be on 
Wednesday afternoon along any outflow boundaries left behind from 
tuesday's convection. Stronger ridging for Thursday into next 
weekend should limit rain chances across the region except for 
some very isolated convection in the coastal plains. Temperatures 
next week will also increase into the mid to upper 90s with lower 
100s in the Rio Grande plains.
