NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1241 am CDT Tuesday may 24 2016 


Aviation... 
no significant changes to ongoing tafs. MVFR cigs will lower 
further through the night to LIFR in Austin and San Antonio. Drt 
will stay MVFR. There is a slight chance for light rain or drizzle 
around sunrise, but probability is low and any light precip will 
not change category. Improvement Wednesday will be slow and cigs 
will not rise to VFR until mid-afternoon.

Previous discussion... /issued 1025 PM CDT Monday may 23 2016/ 


Update... 
Tornado Watch 199 has been allowed to expire as convection has 
dissipated over the Rio Grande plains and the impressive supercell 
complex (with -82 deg c cloud tops and echoes to 68 kft) southwest 
of Eagle Pass in Mexico should stay out of our County Warning Area. A strong cap 
evident on the 00z drt sounding and recent aircraft soundings at 
aus and Sat suggest that only shallow convective shower activity 
would be possible tonight. Hi-res models show very little 
coverage overnight, so have removed pops everywhere except for the 
western Hill Country, Rio Grande plains, and Edwards Plateau. Kept 
a slight chance of thunderstorms along the border just in case 
another cell tries to pop up in any remnant outflow, but the cap 
should prevent this. Very isolated light showers are still 
expected along the I-35 corridor tomorrow morning after sunrise, 
though probably lower in coverage than the last two mornings. 


Previous discussion... /issued 334 PM CDT Monday may 23 2016/ 


Short term (tonight through Tuesday night)... 


Main highlight for the next 36 hours will the the slight to 
marginal risk of strong and severe storms across the Rio Grande 
plains and portions of the southern Edwards Plateau late this 
afternoon and evening. Main risks will be large hail, straight- 
line damaging winds and a brief tornado can not be ruled out. Storm 
coverage and strength is expected to decrease through late evening. 


Scattered light to moderate showers are ongoing across central and 
eastern areas as weak isentropic lift occurs underneath embedded 
mid-level impulses in the SW flow aloft. Luckily a capping 
inversion is in place and limiting vertical extent of this 
activity. Farther west however, warmer low-levels resulting in 
higher mixed-layer instability of 4000-5000 j/kg will be able to 
ignite strong and severe storms across The Big Bend of Texas and 
along the burros mountains. Kdrt model soundings and Storm Prediction Center 
mesoanalysis still suggest a capping inversion in place albeit 
weaker. Storms should initiate farther northwest of the area and on the 
higher terrain where the capping is weaker and then move towards 
Val Verde/Edwards late afternoon/early evening. Very large hail 
could be possible given the cape values and lapse rates in place. 
Downdraft cape is over 1000 j/kg that could result in pockets of 
damaging straight-line winds. Low-level 0-1 km srh is only 50-100 
m2/s2 but 0-3 km srh is upwards of 150 m2/s2 that could support 
the possibility of a brief tornado in this area. 


Storms are expected to weaken into the late evening and overnight 
as they slowly push east/southeast towards the southern Edwards 
Plateau and along the Rio Grande plains. 


Tuesday will feature slightly stronger 500 mb ridging as the dryline 
retreats farther westward. With ridging and capping in place, 
rain and thunder storm chances will be lower. However, if a storm 
were to break through the capping inversion, it could become 
strong. Capping will be slightly weaker over the Hill County and 
the burros again and this area will need to be monitored. 


Long term (wednesday through monday)... 


Potential heavy rain event could take form late week into the 
beginning of Memorial weekend. Multiple model guidance suggests 
an increasing probability of several rounds of heavy rain Thursday 
and then again Friday. Please stay tuned as we approach this time 
frame given the already saturated soil across the area. 


Wednesday will feature additional 500 mb ridging while a deeper 
trough develops across the desert SW of the US. A implied stronger 
shortwave trough will should shift across the Rio Grande plains 
ahead of the parent low pressure system late Wednesday night to 
help usher the first round of showers and storms across the 
region. Greater synoptic lift coupled with precipitable waters  increasing to 
near 1.8" to 2" could lead to very efficient rainfall through the 
day Thursday. A brief break may occur late Thursday night into 
Friday morning but then the greatest synoptic lift will shift 
across south-central Texas Friday afternoon and evening as the 
base of the parent trough shift over the Southern Plains. Again, 
with the ongoing, and by this time likely very saturated soil, 
high amounts of run off are becoming an increasing concern. A 
Flash Flood Watch may be needed for this time period. Please stay 
tuned as details and rain amounts become more clear going into the 
Holiday weekend.
