NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
907 PM CDT Wednesday Sep 17 2014 


Update... 
a quick update issued to reflect lower evening probability of precipitation over western 
and central counties to stress the late night timing of the 
expected heavy precipitation over central Texas. One or two of the 
finer res models suggested a potential for southwestward propating cells in 
the overnight hours to expand the heavy rain threat deeper into 
The Hill Country. A more conservative approach is favored outside 
the watch area as is noted from the minimal inflow from the low level jet as 
noted in the latest satellite precipitation estimate statement product from NESDIS. As outflow 
boundaries intersect over central Texas...the flash flood potential 
will only increase in the early morning hours for the counties in 
the Flash Flood Watch. 


&& 


Previous discussion... /issued 633 PM CDT Wednesday Sep 17 2014/ 


Aviation...reasoning of previous set of tafs appeared fine and no 
changes were made except for initial conditions. Ceilings continue 
to be expected to drop to MVFR at the aerodromes during the overnight 
hours...with VFR likely to resume during the Post-sunrise hours of 
Thursday. Convection will likely affect 3 out of 4 taf sites. 


Previous discussion... /issued 331 PM CDT Wednesday Sep 17 2014/ 


Short term (tonight through Thursday night)... 
morning radiosonde observation data continues to show abundant moisture in place 
across south central Texas with precipitable water values of 2.0" at 
kdrt...which is almost +2 South Dakota above normal. The latest water vapor 
loop also shows northwest flow aloft across the region with plenty 
of middle and upper level moisture from the remnants of Odile. Late 
afternoon radar imagery shows scattered convection ongoing across a 
good portion of south central Texas. We expect this convection to 
continue into the middle-evening hours...then gradually weaken for 
most locations. However...given northwest flow aloft and the 
latest hi-res model guidance...can/T rule out additional 
convection through the overnight hours across portions of The Hill 
Country and adjacent northern I-35 corridor 
(llano...Burnet...Williamson counties). Northwest flow aloft 
persists on Thursday and the latest guidance continues to show 
good potential for additional rainfall for areas generally along 
and north of Highway 71. Based on recent rainfall amounts across 
the mentioned region and the potential for additional rainfall 
tonight and especially Thursday...we have issued a Flash Flood 
Watch. The Flash Flood Watch will run from tonight through 
Thursday afternoon for areas along and north of Highway 71. 
Average rainfall amounts of 1 to 2 inches are expected with 
locally higher totals of 3 to 5 inches possible. 


Long term (friday through wednesday)... 
overall...we have made little changes to the forecast for the 
remainder of this week into early next week. The subtropical ridge 
axis tries to build into the region on Friday. However...the medium 
range models suggest moisture level will not drop significantly on 
Friday and we/ll maintain a 30-50% chance for rainfall. Moisture 
levels to drop a little this weekend...so a decrease to 20-30% rain 
chances looks reasonable. The models continue to struggle with the 
strength of a cold front moving into North Texas on Monday. Recent 
model trends from the European model (ecmwf) have shown a weaker front on the 12z 
run vs. A stronger front on the 00z run. Today/S data follows a 
similar trend and to preserve some consistency...we/ll not deviate 
much from the inherited forecast. We/ll show a northeast to east 
wind shift with the boundary on Monday...but any cold air 
advection should be rather weak. Southeast winds return on Tuesday 
and Wednesday. A 20% chance for showers and thunderstorms will 
remain in the forecast on Tuesday for areas generally south of 
Highway 90 as moisture levels will be higher across our southern 
areas.
