NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
645 PM CDT Tuesday Mar 31 2015 


Update... 
please see the 00z aviation discussion below. 


&& 


Aviation... 
all taf sites are currently VFR...but this will change by late 
evening as low clouds once again develop over south central Texas. 
We/ll continue to mention ceilings developing between 03z-04z along 
I-35...with ceilings delayed to around 08z at kdrt. Ceilings should lower 
into IFR across all areas after 09z and continue through most of 
tomorrow morning. Daytime heating will help lift ceilings into MVFR 
during the afternoon hours...but will also aid in the development 
of showers and thunderstorms. We/ll continue to mention prob30 
group for -tsra along I-35 between 18z-23z. 


&& 


Previous discussion... /issued 257 PM CDT Tuesday Mar 31 2015/ 


Short term (tonight through Wednesday night)... 
an upper level trough finally moving east of Baja California California will 
slowly weaken as it moves across northern Mexico tonight and Texas 
Wednesday. A strong capping inversion is currently over our area 
inhibiting convective development. This will persist this evening 
into the overnight. However...isolated thunderstorms are expected 
along the dryline in western Texas or over the serranias del burro 
of Mexico due to weakening of cap and upward motion there. It is 
possible that some of these may move into areas along Rio Grande 
this evening. Forecast soundings and convective parameters suggest 
a possibility of strong storms over the Val Verde County area and 
concur with Storm Prediction Center highlighting that area for a marginal risk. Cap 
weakens sufficiently late tonight into Wednesday for scattered 
showers with some instability allowing for isolated thunderstorms. 
Convective parameters are weaker and no severe storms are expected 
Wednesday. The showers and thunderstorms end Wednesday evening as 
the trough axis moves off to the east. Above average temperatures 
continue in the short term. 


Long term (thursday through tuesday)... 
the next rain chances are on Friday when an upper level trough 
moving across the Central Plains forces a cold front south through 
south central Texas. There will be sufficient moisture convergence 
along the front for some showers and thunderstorms. The front 
moves through during the midday to afternoon making a possibility 
of isolated stronger storms due to increased convective 
parameters. Weak impulses move through the west to southwest flow 
aloft allowing a weak overrunning pattern to develop with 
isentropic lift creating chances of showers and thunderstorms this 
weekend into Monday. Above average temperatures on Thursday into 
Friday turn well below average this weekend due to cold advection 
along with rain and clouds...and then warm back to above average 
next week due to warm advection and decreased clouds.
