Occasional cloud to ground lightning and brief heavy rainfall that will reduce visibility will be the main concern with these storms. Some wind gusts to near 40 mph are also possible with the stronger storms.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1245 PM CDT Wednesday Jul 27 2016 


Aviation... 
one more day of isolated shower and thunderstorms that could 
impact the terminals through the afternoon. Aus is experiencing a 
break in shower and thunderstorm activity that impacted the 
terminal through the morning hours. More isolated storms are 
currently moving north from baz and hyi that could impact the 
terminal from 19z to 22z. For this reason have included a tempo at 
aus with prevailing thunderstorms in the vicinity at all other sites. Precipitation should 
end around sunset so mention of precipitation has been taken out 
after 23z. 


Another round of MVFR cigs is expected along I-35 through the 
morning hours tomorrow, with some high MVFR cigs are possible at 
drt as well. Winds will remain light out of the southeast but 
could be gusty around any storms that impact the terminals. 


Storms should be more isolated today compared to yesterday and 
Monday evening. Amendments will be made as needed through the 
afternoon if thunderstorms approach terminals.

Previous discussion... /issued 1025 am CDT Wednesday Jul 27 2016/ 


Update... 
persistent small area of thunderstorms on the east side of Austin. 
High resolution models show this area dissipating over the next 
few hours. Regional radar showing a boundary extending to the east 
from this cluster through Bastrop and Lee counties. We will 
continue to watch this region for further development. For now, 
our ongoing forecast looks to be in pretty good shape. My only 
concern is our quantitative precipitation forecast will be too low if storms form along this 
boundary. Will keep an eye on it. 


Previous discussion... /issued 249 am CDT Wednesday Jul 27 2016/ 


Short term (today through thursday)... 


Mid/upper level cyclonic flow has become broad and elongated with 
a shear axis from nern Mexico across the coastal Bend to nrn 
Mississippi. A secondary shear axis at 700 mb extends nwd across 
our forecast area and into ern OK, and model consensus shows this 
feature sharpening today and possibly acting as a increased 
convective focus this afternoon. Another and possibly more 
significant area expected to destabilize is along a mid-level 
moisture gradient over S TX, and models show fair to good 
agreement on the convective focus on this focus expanding 
northward with time later this morning. Thus locally higher pops 
are distributed generally along an an east-west axis 50 miles either 
side of US Hwy 90, but scattered convection remains a possibility 
over all of the forecast area today into early this evening. 


Pwat values will again be in the 1.8 to 2.3 range over much of 
the area, and slow expected storm motions could lead to more 
isolated pockets of 2-3 inch rains. Should this happen over 
certain areas, localized flooding is possible, but most areas 
have not seen amounts over half an inch of rain since the rain 
chances increased Monday afternoon. The severe weather potential statement will likely look 
similar to that of yesterday, with marginal threats for heavy 
downpours and wind gusts, with decreasing threats afterwards. 


Weak shear over south central Texas should limit overnight rain 
chances, and the mid-level shear feature that tightens over 
north-cntrl Texas continues to show better focus for rain chances while 
pwat values suggest better rain chances east of I-35. Thus for 
Thursday, pops are still forecast to be isolated from the San 
Antonio area and points west while low end sct convection remains 
possible over the nrn Hill Country and east of I-35. 


Given the abundance of clouds/convection over the area the next 
couple days, will not stray off the blended guidance which remains 
below normal today and returns to normals for Thursday. 


Long term (thursday night through tuesday)... 


Rain chances continue to shrink ewrd Friday into Saturday as the 
mid/upper level cyclonic shear pattern continues to weaken and is 
replaced with ridging from the west. The 700 mb ridge remains more 
anchored over the sern US and Atlantic, which maintains deeper 
onshore flow and moisture levels into next week. Thus daily 
isolated pops will continue well into the extended over the 
coastal prairies as inland areas continue to bake under the broad 
upper ridging pattern. Another weakness in the mid-upper levels is 
forecast move onshore from the Gulf into Texas by the 00z runs of 
the GFS/ecm for late next week.
