NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
909 am CST Friday Nov 21 2014 


Update... 
to better define severe threat Saturday. 


&& 


Discussion... 
we have decided for consistency to focus the severe threat on 
Saturday afternoon and early evening. Have adjusted weather grids 
to reflect this. Otherwise forecast looks good for now. 


&& 


Previous discussion... /issued 548 am CST Friday Nov 21 2014/ 


Aviation discussion...for 12z taf package... 
a complex forecast for this taf period as low level moisture is 
plentiful resulting in MVFR/IFR/LIFR categories in visible and ceiling 
throughout the night. These conditions will likely persist through 
the morning hours before all terminals generally improve to MVFR 
ceilings by middle day. Kaus/kssf/ksat terminals should experience 
isolated to scattered shower activity throughout the day as well 
with possible -tsra in the afternoon. By nightfall...br should 
return for all terminals to at least MVFR. 


An approaching storm system will impact all terminals tomorrow 
morning with highest chance at kaus so included prob30 late in the 
period for planning purposes beyond 24 hours.

Previous discussion... /issued 409 am CST Friday Nov 21 2014/ 


Short term (today through saturday)... 
cloudy skies and patchy fog have overspread south central Texas 
overnight as continued southerly flow pumps in warmer temperatures 
and higher moisture into the area. The weak lift associated with 
the warm air advection has led to isolated shower development 
since yesterday and this will continue mainly across the eastern 
zones early this morning. Currently...the low-level flow is south-southwest in 
the lowest 4 km of the atmosphere. By the afternoon most guidance 
members are backing the winds to the south-southeast and increasing the low- 
level jet in response to the approaching upper low which is 
currently over Southern California per latest water vapor 
analysis. The backing of the wind and increasing of the speed will 
lead to a strong push of positive Theta-E advection beginning 
in the southeast zones...near the coastal plains this afternoon. 
The nose of the increasing Theta-E values will then push northwest 
to the I-35 corridor by 6 PM and then The Hill Country and Edwards 
Plateau by midnight. Positive Theta-E advection is a direct 
measure of increasing temperature/moisture which is lift. This 
lift can also be seen on isentropic charts on constant Theta 
surfaces. Expect about a 50 to 60 percent coverage of showers and 
thunderstorms in the form of a broken line beginning this 
afternoon across the southeast and then moving northwest through 
midnight. 


As we get into tomorrow morning...continued weak lift on 
isentropic charts will result in isolated to scattered activity 
across much of the area. Also by tomorrow morning...the upper low 
is prognosticated to be near northern Mexico...entering West Texas. 
Models are in fairly good agreement with the placement and 
strength of the low as it progresses through the area. This low is 
expected to transition from a positive tilt to either a neutral or 
slightly negative tilt as it moves over the area Saturday 
afternoon. A negative tilt to an upper trough is more conducive 
for thunderstorm development as upper diffluence commences ahead 
of the trough. Models are forecasting the center of the strongest 
lift of the upper low to move across The Heart of our County Warning Area as is 
evident by the peak tropopause fold to 430 mb over San Antonio 
Saturday night. This should equate to substantial upper forcing 
for ascent and will lead to widespread shower and thunderstorm 
activity across much of if not all the County Warning Area. The question then 
turns to the instability/shear parameters and any mesoscale 
features that come into play for severe weather chances. 


Models are in fairly good agreement that there will be around 750 
to 1500 j/kg of surface based cape across much of the area 
Saturday. This amount of instability in addition to 40 knots of 
0-6 km shear will be sufficient for organized convection. The main 
limiting factor will be the amount of activity and what effect 
that will have on severe chances. If there is too much of a 
coverage of activity...it will be difficult to realize the peak 
instability values. Nevertheless...the most likely scenario will 
be widespread activity with embedded rotating thunderstorms as the 
activity moves from west to east during the day Saturday. Large 
hail and damaging winds will be the main threats. The sherb index 
is a forecast tool to help with these high shear/Low Cape events 
and current forecasted values are above 1.0 which is favorable for 
severe convection...mainly in the form of a qlcs or individual 
line segments. This seems reasonable and can somewhat be seen on 
the high-res models. The tornado threat is non-zero given the 
amount of low-level shear expected over the area. Would like to 
see more discrete activity and a focused surface boundary over the 
area to expect anything greater than isolated tornadoes. 


Models mostly agree that the activity will shut off from west to 
east pretty rapidly in the afternoon. By 6 PM...the back edge of 
the convection should be just east of the I-35 corridor. Dry west 
winds from the surface to 850 mb will move in ahead of the upper 
low and this will end things. The outlier is the NAM which is 
developing another line of storms around 6 PM west of the I-35 
corridor...but the NAM 850 winds are unrealistic. It keeps the 
west wind shift directly underneath the 500 mb low...while the 
rest of the guidance members have the wind shift ahead of the low 
which is more realistic. 


The last thing to focus on is the heavy rain potential across the 
area. The highest rain totals will be across the eastern and 
northern zones. Moisture should pool up nicely in that corridor 
as a weak surface low develops just north of our County Warning Area. Precipitable water values 
will be around 1.5 or about 2 Standard deviations above the mean 
for this time of the year. These areas will likely receive 1 to 2 
inches of rain with isolated locations picking up 4 inches. 


Long term (saturday night through thursday)... 
the rest of the thunderstorm activity will be exiting the area by 
midnight Saturday night. Dry west winds will be left in place 
Sunday and this should be a warm and sunny day for the area with 
highs reaching lower to middle 70s. A longwave trough will pass 
through the plains Sunday and will send a dry front into the 
region by Monday morning cooling things off once again. The rest 
of the week should remain dry with highs in the 60s and lows in 
the 30s/40s. Thanksgiving looks dry and seasonal.
