NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
650 am CDT Thursday Sep 18 2014 


Aviation... 
the area of rain showers/thunderstorms and rain is decreasing as it moves south. Will go 
with tempos of rain showers for kaus...ksat and kssf until middle morning. 
Scattered-numerous rain showers/thunderstorms and rain will develop as the day progresses and have 
mentioned vcsh at all tafs. The hi-res arw shows an mesoscale convective system moving 
across the area and have gone with prob30s for all taf 
sites...this evening at kdrt and overnight at kaus...ksat and 
kssf. Ceilings lift to VFR late morning into afternoon. MVFR ceilings 
redevelop overnight tonight and then lift back to VFR by midday 
Friday. East to southeast winds 10 kts will prevail. Some gusts to 25 kts 
possible in and near shra/tsra.

Previous discussion... /issued 401 am CDT Thursday Sep 18 2014/ 


Short term (today through friday)... 
small area of very heavy rain continues to drop south along the 
I-35 corridor. This area will slowly decrease early this morning 
by around sunrise. Middle level remnants of Odile will move slowly 
east-northeast from southeastern Arizona to eastern New Mexico 
continuing a supply of moisture from the tropical Pacific. A weak 
southeasterly lower level flow maintains a supply of moisture from 
the Gulf of Mexico. Well above seasonal average precipitable waters  of 2 to 2.3 
inches will linger over south central Texas. Favorable upper level 
jet and weak disturbances spinning off of Odile track across 
central Texas. Have maintained scattered to numerous showers and 
thunderstorms for today with the highest probability of precipitation and locally heavy 
rainfall mention across the northeast in proximity to the jet and 
disturbances. Kept Flash Flood Watch going as soils are saturated 
in many areas of the watch area due to ongoing and earlier very 
heavy rains and additional rainfall will lead to flash flooding. 
Most models decrease rainfall tonight. However...hi-res arw shows 
an mesoscale convective system developing and moving across much of south central Texas. 
Will indicate locally heavy rains for this possibility. Scattered 
showers and thunderstorms develop again Friday. Temperatures will 
be near middle September averages. 


Long term (friday night through wednesday)... 
remnants of Odile drift from New Mexico into western Texas this 
weekend. A southerly middle level flow maintains eastern Pacific 
tropical moisture while a southeasterly lower level flow maintains 
Gulf of Mexico moisture. Isolated to scattered showers and 
thunderstorms are expected this weekend. Remnants of Odile 
dissipate or drift to the northeast allowing moisture levels to 
finally decrease early to middle of next week. However...a surface 
boundary or weak cold front drops into southern Texas. Moisture 
convergence along boundary/frontal zone should be sufficient for 
isolated showers and thunderstorms Monday through Wednesday. 
Near late September average temperatures are expected. 


Hydrology... 
creeks in the Austin area will continue to run high for the next 
few hours due to the ongoing and earlier very heavy rains.
