NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
946 PM CDT Monday Sep 15 2014 


Update... 
overall...short-term forecast is on track with only minor 
adjustments made to the overnight sky and weather grids. 
Latest nam12...sref and ruc13 solutions show an area of isolated 
showers overnight across the I-35 corridor...especially over 
parts of Comal...Hays and Travis counties. Therefore...increased 
pop across that area to a 20%. Still look good for rain chance 
late Tuesday into Wednesday and Thursday as tropical airmass 
arrives from the south at lower levels and from the northwest at 
middle to upper level. 


&& 


Previous discussion... /issued 657 PM CDT Monday Sep 15 2014/ 


Aviation... 
high pressure should hold back cloud cover to VFR through at least 
07z despite a good amount of available moisture and southeasterly low level 
winds. Some isolated sea-breeze convection forming over the 
coastal Bend is suggested to shift focus to the I-35 taf sites by 
the finer res model data toward midnight...but with slow storm 
motions noted...will leave this feature out of the tafs for now. 
Abundance of high clouds could delay the MVFR ceiling development late 
tonight and will look at a possible update for this shift as 00z 
model data arrives. Late in the period...a weak surface low moves 
onshore into deep S Texas and northwest flow develops aloft...leaving more 
favorable conditions for convection in the afternoon and early 
evening. 


Previous discussion... /issued 305 PM CDT Monday Sep 15 2014/ 


Short term (tonight through Tuesday night)... 
isolated showers continue over The Hill Country and Edwards 
Plateau...but amounts are negligible and the showers should move 
off to the northeast and out of our area by 00z. The primary short 
range issue is the increase in moist air...at low and middle-levels 
from the Gulf...and at middle- and upper levels from Pacific Hurricane 
Odile. We expect sprinkles tonight as the moist Gulf air (pw over 
2 inches) undergoes gentle lift due to terrain. Without a significant 
low level source of lift other than a weak sea-breeze...we expect 
scattered probability of precipitation and modest quantitative precipitation forecast Tuesday and Tuesday night. Temperatures will 
remain slightly below normal with extensive cloudcover and scattered 
storms. 


Long term (wednesday through monday)... 
higher probability of precipitation and quantitative precipitation forecast are forecast for Wednesday and Thursday as 
Odile becomes extratropical and is sheared/absorbed by a shortwave 
trough moving through the southwestern states. Precipitable water should be at or 
above two Standard deviations above normal for September...so when 
combined with general lift ahead of the trough axis...will bring 
more substantial convection. However...without a source of low- 
level lift and focus...we still expect quantitative precipitation forecast to only be in the 1/4 
ot 1/2 inch range at many sites for Wednesday through Friday. 


The southwestern states trough is slow to move over the weekend... 
and may be bolstered by another eastern Pacific tropical cyclone 
by Sunday/Monday. We decided to maintain probability of precipitation each day...but less 
coverage and with low quantitative precipitation forecast due to a lack of low-level focus. 
However...lesser cloudcover and convection should allow 
temperatures to rebound to near normal. Longer range models 
indicate a cold front passage just beyond this forecast (middle of 
next week)...which should lead to continued low to moderate probability of precipitation 
and near to slightly below normal temperatures.
