NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
656 am CDT Monday may 30 2016 


Aviation... /12z tafs/ 


Complex of storms surging south across Sat/ssf in the first couple 
hours of the taf period...with stratiform rain and occasional 
lightning resulting in improvements over aus. A delayed wind shift 
at drt should arrive at 13z and be followed shortly by vcsh and 
possibly some scattered thunderstorms and rain in the area in the few hours to 
follow. Stabilized conditions are expected in the late morning for 
a few hours...with a possible midday recovery of low clouds to 
MVFR levels before resuming as VFR cumulus. A worked over airmass 
should lead to a mostly fair evening, then trending to more MVFR 
to IFR ceilings late. Mesoscale models show poor agreement on how fast 
he air destabilizes in the wake of this mornings complex, so will 
keep the later taf periods simplified until details become 
apparent. 


&& 


Previous discussion... /issued 327 am CDT Monday may 30 2016/ 


Short term (today through tuesday)... 


.Localized heavy rain and flash flooding possible this 
morning... 


Main focus this period will be on the incoming thunderstorm line 
that is approaching south-central Texas this morning. Pockets of 
heavy rain are expected as the line moves through and localized 
flash flooding could occur given the very saturated soil from 
the recent abundant rainfall. A Flash Flood Watch is in place for 
The Hill Country and portions of the Edwards Plateau through 1pm. The 
flash flooding risk should decrease through the early afternoon as 
the line weakens and moves south. 


A large mesoscale convective system developed across the Panhandle of Texas last night 
and is now moving south towards The Hill Country and northern 
I-35 corridor. This line will move in over the next several hours. 
Rainfall rates have been around an inch to inch and half with the 
southward progressing line. A few showers have also developed 
ahead of the line in Kerr and this area (along with the hill 
country) will need to be monitored for local enhancement and 
sustainability of stronger updrafts resulting in higher rainfall 
totals. Low-level flow is balanced well with the strong cold pool 
of the storm complex and this will sustain the current strength of 
the complex as it moves south. Pockets of 30-50 mph winds will 
also be likely with the line as it moves through. 


The complex should slowly weaken through the mid to late morning. 
This will likely result in a lull of shower activity across a good 
portion of the region through early to mid afternoon as the 
atmosphere attempts to recover. Hi-res models have done a poor job 
over the past 24 hours, so little confidence is being placed in 
them currently. Of the ensembles that do show the current line, 
some renewed activity could be possible late afternoon and 
evening as a 500 mb impulse moves over the region helping increase 
upper level divergence. In addition to this activity, West Texas 
and the Burro Mountain range should also see storm development. 
Will need to monitor if this activity can make it off the 
mountains and cross the Rio Grande. 


Overnight and into Tuesday morning should see a slow decrease of 
rain/storms for western areas but continued SW flow aloft and 
implied shortwave troughs make it difficult to remove all weather 
mention during any period. Scattered showers and thunderstorms are 
again expected Tuesday afternoon under this regime. Will need to 
monitor closely if any complexes are able to develop for a more 
concentrated rainfall hazard Tuesday. 


Long term (wednesday through sunday)... 


More rain is expected mid- to late-week as a weak front stalls 
over the region and then a mid- to upper-level low develops and 
moves very slowly over Texas. Periods of heavy rainfall could 
occur Wednesday into Thursday with more scattered activity late 
week and weekend. With area soils so saturated, localized flash 
flooding could be a possibility again over a larger swath of the 
region. 


A deep, closed low developing across northern Mexico by Wednesday is 
agreed upon my multi model guidance. Stronger 500 mb flow along with 
ample moisture and a weak front across the region will support 
widespread showers and thunderstorms Wednesday into early 
Thursday. With precipitable waters  1.8"-2.0", localized areas of heavy rainfall 
could occur. It's possible that a new Flash Flood Watch could be 
issued during this time frame. 


The mid- to upper-level low is forecast to get cut-off from the 
main flow and will stagnate over Texas late week and early 
weekend. This will keep higher rain chances and below normal 
temperatures in place. Given the cooler conditions, instability 
may be lower and thus convective rainfall rates could be more 
difficult to occur. Overall rainfall amounts mid-week to the 
weekend could be 2-4 with locally 5 inches. If more sun and 
instability was able to occur within the upper-low then higher 
rainfall rates could be locally possible. This will need to be 
looked at on a day by day basis. Deeper northwest flow should develop on 
the back side of the slowly exiting low/trough by late weekend 
and early next week. This should allow for drier and continued 
cooler than normal conditions.
