NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1240 am CDT sun may 1 2016 


Aviation... 
all terminals are currently VFR. MVFR ceilings will develop at all 
sites between around 10z and 12z. Ceilings will likely remain MVFR for 
the rest of the period. Expecting convection to develop sometime 
this afternoon and evening. Have included prob30 groups starting 
at 20z at drt and after 00z at Austin and San Antonio. Thunderstorms and rain should 
reduce visible...but not affect ceilings.

Previous discussion... /issued 310 PM CDT Sat Apr 30 2016/ 


Short term (tonight through Sunday night)... 
late afternoon surface observations show a cold front along the 
coastal plains with surface high pressure over the Texas 
Panhandle. This pattern will continue to provide northerly winds 
for most areas through this afternoon. The exception will be near 
the coastal plains where some weak easterly winds are expected. 
The cold front is expected to remain across the coastal plains 
this evening...then begin lifting northward as a warm front 
overnight. Given the higher moisture levels near the coast... 
we/ll mention a slight chance for showers tonight for areas along 
and south of a La Grange to Pleasanton line. On Sunday...surface 
high pressure will build across West Texas...with northeast to 
easterly low-level flow across south central Texas. Meanwhile... 
the upper level southwesterly flow will become active as a 
subtropical jet remains over deep south Texas. We expect showers 
and thunderstorms to gradually increase throughout the day on 
Sunday...especially along the Rio Grande plains given strong 
southeasterly flow in the low-levels. Daytime heating and 
additional lift should lead to a gradual increase in coverage of 
showers and storms Sunday afternoon into Sunday evening. We could 
see a few strong to severe thunderstorms across the region... with 
large hail being the main concern. Surface high pressure 
strengthens over south central Texas late Sunday night. Additional 
isentropic lift will continue to provide a good chance for showers 
and storms through Sunday night. 


Long term (monday through saturday)... 
surface high pressure continues to build into the region on Monday 
as the flow aloft transitions to a more westerly direction. We 
expect a decrease in rain chances from north to south on Monday... 
and especially Monday night. For Tuesday through Friday...we still 
expect middle-level ridging to build across the south Central Plains. 
This will lead to dry weather and a gradual warming trend for the 
mentioned period. Late in the forecast...another upper level low 
will develop over the southwestern U.S. For now...we/ll show a 
return of rain chances to the southern Edwards Plateau and Rio 
Grande plains on Saturday...with rain chances likely to increase 
and spread eastward just beyond the current forecast period.
