Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
640 am CDT Thursday may 26 2016 


Aviation... 
isolated to scattered convection has developed north of Austin and 
will mention thunderstorms in the vicinity in the tafaus for the morning hours and vcsh 
for the San Antonio sites. MVFR/IFR ceilings are in place this 
morning and these should hold until around noon. Should see a 
break in rain chances in the early afternoon hours before 
additional storms are likely in the late afternoon and evening 
hours. Will cover this threat with thunderstorms in the vicinity for now. Another round of 
MVFR or IFR ceilings can be expected tonight.

Previous discussion... /issued 350 am CDT Thursday may 26 2016/ 


Short term (today through friday)... 
upper air analysis last evening showed a trough from the Great 
Basin to Southern California with west-southwesterly flow over Texas. This 
was bringing mid-level moisture from the Pacific across Mexico. At 
the surface, there was a dryline over West Texas and east of this 
feature winds were from the southeast across our County Warning Area. Dewpoint 
temperatures were in the mid to upper 70s. During this period the 
upper level trough will move from the southwest into the Central 
Plains with the trough axis moving into central Texas by the end 
of the period. The low level flow will continue to be from the 
southeast today and tonight. Precipitable water values will increase to around two 
inches over the southeastern part of the County Warning Area this afternoon. This 
looks to be the favored location for showers and thunderstorms 
this afternoon. With precipitable water that high, locally heavy rain is possible. 
Thursday evening a shortwave trough will move through the pattern 
and initiate thunderstorms near the dryline. These storms will 
develop over our northwestern area and move toward the southeast 
into a moisture rich atmosphere. Locally heavy rain will continue 
to be possible. In addition, convective parameters suggest 
possible severe thunderstorms over the western 2/3 of the area with 
cape 2000-3000 j/kg, deep layer wind shear 30-40 kts, and steep 
mid-level lapse rates. Large hail and damaging wind gusts are the 
most likely threat with isolated tornadoes possible. Friday the 
dryline will move through the western half of the area. Expect 
that thunderstorm development will not happen until afternoon over 
the eastern half of the County Warning Area. Convective parameters are again 
suggestive of severe storms over the eastern half of the area. 
Damaging wind gusts and isolated tornadoes are the most likely 
threats. Rainfall totals from this afternoon through Friday 
afternoon will be one to three inches with isolated amounts up to 
five inches possible. 


Long term (friday night through wednesday)... 
the upper level pattern will become zonal Friday night as the 
trough moves away to the northeast. This pattern will continue 
through the weekend and the early part of next week. The low level 
flow will remain mostly from the southeast keeping moisture high 
in the boundary layer. This will keep the atmosphere conditionallyunstable 
and allow weak perturbations in the mid to upper flow to produce 
thunderstorms. Will carry slight to low end chance pops each day. 
The reality is most places will be dry, but there will likely be 
some convection each day. Models do not suggest any organized 
systems through the long term.
