NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1100 am CDT Sat Aug 1 2015 


Update... 
drier air filtering into eastern areas of south central Texas with 
dewpoints about 10 degrees less than yesterday and precipitable waters  falling to 
around 1.2 inches. This drier air will slowly spread west today. 
However...sufficient moisture remains over the Edwards Plateau and 
Rio Grande plains for isolated to widely scattered showers and 
thunderstorms. Have removed probability of precipitation for the remainder of this morning 
as no development is ongoing and convective temperatures will not 
be reached until after noon. Remainder of south central Texas 
forecast is on track.

Previous discussion... /issued 618 am CDT Sat Aug 1 2015/ 


Aviation... /12z taf update/ 
VFR skies are forecast at taf sites through the next 24-30 hours. 
Weak divergence pattern and dry northeast surface winds should 
lead to little or no overnight stratus below 3000 feet...and dry air 
around the I-35 terminals should limit the potential for fog. A 
few visibility restrictions could occur through 15z over The Hill 
Country and any areas that received a heavy shower from Friday. Storms 
could impact drt this afternoon with shifty outflow winds that 
should diminish in the early evening. Pockets of middle level 
cloudiness could spill into The Hill Country from the north 
tonight...but taf sites should see a decreasing middle level cloud 
trend due to drier air moving in from the northeast. 


Previous discussion... /issued 301 am CDT Sat Aug 1 2015/ 


Short term (today through sunday)... 
convection from yesterday afternoon has ended across the area and 
we are only left with anvil debris. Winds are light and variable 
and temperatures are currently in the middle 70s. As heating 
occurs this morning east winds just off the surface...as seen on 
area VAD wind profiles...will be able to mix down to the surface 
and this easterly flow is expected to prevail into tomorrow. The 
airmass to our east is much drier with 60-65f dewpoints in place. 
This means that dry-air advection will be in place across much of 
the area limiting thunderstorm chances. The dry air is evident on 
forecasted cape fields with only small values of instability 
remaining across the western counties. Precipitable water values in this region 
will remain above 1.5 inches as the driest air remains east of 
this area. Will continue 20-30 probability of precipitation this afternoon for locations 
west of an Eagle Pass to Kerrville line. Temperatures are 
expected to be in the upper 90s to 102 degrees and any 
thunderstorms that do develop could produce gusty winds given 
ample dewpoint depressions. The drier air will limit the potential 
for higher heat indices this afternoon across the area. 


Dewpoints in the 50s/60s will continue on Sunday once again 
keeping heat index values below 105 across the area. Highs will 
be in the 96-102 degree range with the cooler temperatures across 
the northern Hill Country and the warmer temperatures closer to 
the Rio Grande. The atmosphere will be too dry across our entire 
County Warning Area for any rain chances on Sunday. 


Long term (sunday night through friday)... 
the extended forecast looks to be rather quiet as high pressure 
re-anchors to our west and builds in strength through the work- 
week. Southerly flow will slowly increase surface dewpoints 
through middle-week and we should see the heat indices slowly climb 
as well. Thursday looks to be the hottest day as 850 temperatures warm 
above 25c across much of the area. This should equate to high 
temperatures near or above 100 degrees for much of the area 
excluding the northern Hill Country. Afternoon dewpoints in the 
middle 60s will allow heat index values to be above 105 for much 
of the area. The long term portion of the forecast will remain 
rain free.
