NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
703 PM CDT Monday Jul 25 2016 


Evening update... 
isolated to scattered showers and storms have continued to slowly 
progress farther southwest into the Austin area and surrounding 
locations through 7 PM. So far, this convection has resulted in 
some very localized rainfall totals of between 1 and 2 inches, 
namely in the Jollyville area in Travis County. Some half inch to 
inch amounts were seen with earlier cells in northern Bexar and 
Comal counties. 


Latest hrrr and ttu WRF show this activity continuing to push 
southwest and persist until about midnight. Most concernable 
factor is high pwats this evening, namely 2"+ from the I-35 
corridor and east, maxing out at 2.4" near College Station. Thus, 
isolated heavy rainfall will continue to be a threat with this 
activity through the evening hours. Should this activity congeal 
into more organization...some spots could see a quick 2+ inches 
of rainfall...wherever that occurs. Could result in some minor 
urban flooding. 


As a result, increased pops for the evening hours and accounted 
for the decrease in coverage noted in the high res suite after 
midnight.

Aviation.../00z taf cycle/ 


Scattered thunderstorms and rain is ongoing just north and west of kaus and is over 
katt as of 2345z. A wind shift to the east due a localized gust 
front is moving through kaus currently with gusts to near 15-20 
knots. Winds will weaken to near 10 knots within the next hour 
and return more southeasterly. Additional thunderstorms and rain is located farther 
north and east of kaus and ksat and this could impact both sites 
periodically through the evening. Have placed tempo group in for 
this activity as it slowly decreases after 05z. 


A strong outflow boundary is east of kaus/ksat as of 2345z and 
could help develop renewed thunderstorms and rain activity farther south towards 
ksat/kssf. For this reason, have also placed a tempo group there. 
Kdrt will be clear of most thunderstorms and rain this evening as Hill Country 
storms should diminish before reaching the Rio Grande plains. 


A lull in activity is expected late overnight and through morning 
but scattered to numerous thunderstorms and rain is expected to redevelop near and 
after 18z for most taf sites Tuesday. Have placed thunderstorms in the vicinity in for now 
and will likely add direct thunderstorms and rain wording on either the 06z or 12z 
tafs when timing and coverage confidence increases based on 
latest trends. 


Previous discussion... /issued 314 PM CDT Monday Jul 25 2016/ 


Short term (tonight through Tuesday night)... 
the latest water vapor satellite loop shows a weak upper 
disturbance over East Texas this afternoon. The water vapor loop 
also shows a broad area of low pressure and convection over the 
northern Gulf of Mexico. The satellite-derived total precipitable 
water product shows moisture levels have increased today with 
current values ranging from 1.75" along the Rio Grande to 2.0" 
over the coastal plains. 


The upper level disturbance over East Texas will drift 
southwestward into south central Texas through tonight. Daytime 
heating along with increased moisture will result in scattered 
showers and thunderstorms this afternoon and evening. We have 
already seen an increase in convective activity this afternoon and 
with continued heating, this trend will continue. Most activity 
will likely be tied to daytime heating. However any remnant 
outflow boundaries and subtle lift should continue isolated to 
possibly scattered convection tonight. The upper disturbance 
currently over East Texas will drift west of the Rio Grande by 
Tuesday afternoon as the broad low in the Gulf slowly moves 
westward toward the region. With continued moisture advection and 
daytime heating, our rain chances will increase into the 50-60% on 
Tuesday. Given plenty of moisture (pwats of 2.0-2.3") and slow 
storm movement, can't rule out some locally heavy rainfall. It 
will be difficult to pinpoint where the heaviest rain will occur 
as much will likely depend on any remnant outflow boundaries from 
earlier convection. 


Long term (wednesday through monday)... 
broad, cyclonic flow aloft and deep layer moisture will persist 
across south central Texas on Wednesday. This along with daytime 
heating should be enough to generate another round of scattered 
convection, mainly during the afternoon and evening hours. For 
now, we will keep rain chances in the 30-50% range, but this may 
need to be increased if subsequent model trends remain consistent. 
The broad area of low pressure aloft continues to weaken on 
Thursday, leaving a col over south central and eastern TX. Rain 
chances will decrease, but given plenty of moisture and daytime 
heating we should see at least isolated diurnally-driven 
convection across most of the region. Temperatures will also begin 
to creep upward on Wednesday and Thursday, but are forecast to 
remain near climatological normals. The upper pattern changes 
little through the end of the week, but the atmosphere will begin 
to slowly dry out. While we can't rule some additional isolated 
convection over most areas, suspect the coastal plains will be 
favored given the afternoon sea breeze. Temperatures will also 
rise back to above normal with lows in the 70s and highs in the 
mid 90s to near 100.
