NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1238 am CDT Friday may 29 2015 


Aviation... 
squall line along a kdrt to ksat to kaus to ktpl line at initial 
29/06z time of tafs. Will carry winds of 25g45kts and 1sm +tsra at 
the taf sites. Then transition to 5sm -tsra for the remainder of 
the overnight as area of -ra with occasional ts follows the squall line. 
Ceilings/visibilities will be a mix of IFR to VFR. IFR/MVFR ceilings will become 
more widespread early Friday morning. Isolated/scattered rain showers/thunderstorms and rain are 
possible Friday afternoon into evening. However...will leave 
mention out of tafs due to low probs. Ceilings lift to VFR with clouds 
becoming scattered-broken in the afternoon. IFR/MVFR ceilings redevelop Friday 
evening into night. North-northwest winds decrease to 10 kts or less after 
the initial squall line and then turn to southeast-S by morning and 
increase to 10 to 15 kts by midday Friday. 


&& 


Previous discussion... /issued 808 PM CDT Thursday may 28 2015/ 


Update... 
Severe Thunderstorm Watch has been issued for the northern Hill 
Country and Edwards Plateau. A strong to severe line of showers 
and storms is just northwest of our County Warning Area but will continue to be 
fed by a rich and unstable airmass and the line should have no 
problem surviving for the next few hours. Should see some gradual 
weakening later this evening as the atmosphere stabilizes a 
bit...but showers and storms should continue to move southeast. 
Rainfall amounts still should be in the 1-2 inch rain on average 
with isolated higher amounts. It wont take much to aggravate 
already saturated soils. Given the expected forecast for 
tonight...increased probability of precipitation areawide by 10 to 20 percent. 


Previous discussion... /issued 703 PM CDT Thursday may 28 2015/ 


Aviation... /00z taf update/ 


Hi-res models suggest that the convective line will likely impact 
drt after 02z with isolated cells over Mexico possibly forming and 
joining into the line from Mexico by 03z. Impacts of the line 
should be after 06z along I-35 with improvements to follow the 
convection at roughly 3 hours after the onset. Some bowing 
segments of the line could result in spotty wind gusts to near 40 
knots...with the chance of strong gusts decreasing gradually 
after midnight. Downdraft air should result in some improvements 
to skies...but with the complex expected to weaken overnight... 
will show more pessimistic skies around daybreak. 


Previous discussion... /issued 307 PM CDT Thursday may 28 2015/ 


Short term (tonight through Friday night)... 


Locally heavy rainfall possible across much of area tonight and 
potentially Saturday and Saturday night... 
severe storms possible across Hill Country and Rio Grande 
tonight... 


Scattered thunderstorms have developed this afternoon across the 
eastern half of the County Warning Area in an unstable airmass and rich moisture 
plume. A few strong storms have developed...including tropical 
funnels reported in the Austin/Round Rock area. Overall this 
activity should diminish towards sunset. 


However...main concern will be developing convective complex 
coming out of West Texas and storms coming out of Mexico. Storms 
have already developed across West Texas and are beginning to form 
in the higher terrain of Mexico...all in advance of approaching 
shortwave coming out of nm. Storms developing in the Burroughs of 
Mexico could cross into Val Verde County early this evening. 
MUCAPE exceeding 4000 j/kg and effective bulk shear of 35 kts will 
support storms capable of producing large hail and damaging 
straight line winds across Val Verde County. An isolated tornado 
can not be ruled. 


Several hi resolution models develop the West Texas convection 
into an mesoscale convective system this evening with propagation southeast into a 
strengthening 35 knots low level Theta-E advection axis up the Rio 
Grande plains. The potential mesoscale convective system should make it into the Rio 
Grande and northern Hill Country 02z-06z. Severe potential is 
possible in this area...for mainly straight-line winds. 


Farther eastward into the I-35 corridor...the convective complex 
will be encounter increasing cin and weaker low level jet. Much 
will depend on how strong of a cold pool develops behind the 
complex. The hrrr and nam12 do bring the complex through the I-35 
corridor...while Texas tech 4km WRF and global models weaken the 
system. There is enough uncertainty...and out of an abudance of 
caution given the saturated conditions across the area...to expand 
the Flash Flood Watch east through the I-35 corridor. 


Fridays forecast will depend highly on what happens tonight. A 
organized complex that makes it through the County Warning Area may stabilize 
conditions for much of the day. A weakening complex...leaving 
potential outflow boundary in an unstable environment...may 
result in higher probability of precipitation across the central and eastern County Warning Area Friday. 


Long term (saturday through thursday)...models are coming into 
better agreement with middle and upper level trough axis sliding 
across the Southern Plains Saturday and sharpening across 
East Texas/AR/la Sunday into Monday. This will send a cold front 
into the area late Saturday...and good chances for rainfall across 
the central and eastern County Warning Area Saturday and Saturday night. Higher 
precipitable waters  will remain pooled ahead of the front and slow movement of 
the front could potentially lead to some local pockets of heavier 
rainfall. GFS and European model (ecmwf) generally in agreement better chances of 
rainfall shift south and east with the front Sunday...but will 
have to watch this closely if the front ends up stalling with a 
weaker upper trough axis to the east. 


Looks like drier conditions do develop Monday through 
Wednesday...although not totally removing probability of precipitation across the 
southeast zones/coastal prairies where better moisture is pooled 
and closer to the lower heights with trough axis just to the 
east.
