Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:09 am CDT on July 30, 2015


... Elevated afternoon heat index values continue today into
Friday...

High temperatures will again reach into the upper 90s to near 103
across much of south central Texas today and Friday. Humid
conditions will persist with only light to moderate breezes in the
early to middle parts of the afternoon... making for uncomfortable
outdoor conditions and rising heat index values. Maximum
afternoon heat index values today and Friday should be mainly in
the 104 to 108 degree range... with the hottest conditions expected
generally south and east of a line from del Rio to Bulverde to
Liberty Hill.

Late afternoon and evening thunderstorms will be possible today
and Friday... possibly bringing gusty outflow winds and some
slight relief from the heat in the evening and overnight hours.

Take extra precautions if you plan to be outside. When
possible... reschedule strenuous afternoon activities for the early
morning or evening hours. Know the signs and symptoms of heat
exhaustion and heat stroke.

If you are outdoors... drink plenty of water... wear light weight
and light colored clothing... and take frequent breaks from the
heat. Never leave a child or pet unattended in a vehicle... as
interiors can reach lethal temperatures in a matter of minutes.
Beat the heat... check the back seat!

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
633 am CDT Thursday Jul 30 2015 


Aviation... 
some low stratus has in fact formed mainly over the S and southeast 
counties...affecting ssf and soon to affect Sat with likely IFR 
through the morning. Satellite is not showing much in the way of 
low clouds for aus and drt but will watch closely. Have mention of 
some MVFR/IFR visby as well through the morning as light and 
variable winds have allowed some sites to drop to 1-2 miles. All 
this should burn off by late morning...giving way to VFR through 
the day. We saw a few sh/ts form yesterday afternoon off to the 
east of the taf sites...chances are still too low for any mention. 
Chances are increasing however and by Friday may see some convection 
get into the vicinity of aus/ssf/Sat. 


&& 


Previous discussion... /issued 349 am CDT Thursday Jul 30 2015/ 


Short term (today through friday)... 
heat indices remain a concern for the next couple days with areas 
along and southeast of the Escarpment possibly reaching 105 to 108 
degrees. Some relief from the heat is expected to begin as early 
as this evening...as an influx of middle-level moisture from the 
east is expected to bring an increased chance of rain and upper 
level high pressure weakens a bit over East Texas. Isolated to 
scattered thunderstorms with strong outflows should form over East 
Texas with a few cells developing generally along and east of Highway 
281 late today. The hot temperatures and slightly drier air in the 
lower levels will result in a sufficient profile for a few storms 
to produce wind gusts well in excess of 40 miles per hour. The moisture 
uncertainties remain a concern for today so am expecting the 
convection to have a hard time getting established and keep probability of precipitation 
at or below 20 percent. Surface dew-points are also expected to 
be a 1-3 degrees drier than from Thursday afternoon...so this 
slight change is expected to nudge aus/Sat to their first 100 
degree days of the year. 


Am not expecting enough downdraft activity late today to make an 
impression on surface conditions for Friday when the heat indices 
climb again. By Friday afternoon...GFS/NAM both show significant 
improvements in precipitable water values into the 1.8 to 2.2 inch range which 
should be enough to generate some strong storms. Upper ridging 
aloft continues to heat temperatures to near triple digits so will 
continue to need mention the hot conditions in the sps/hwo. Model 
forecast dcapes are in the 1000-1500 j/kg range which could be 
sufficient to produce an isolated severe downdraft or two. Will 
mention winds gusts to around 50 miles per hour in the severe weather potential statement. 


Long term (friday night through wednesday)... 
while thunderstorm coverage Friday afternoon and evening may be 
mostly in the 20-30 percent range for much of south central 
Texas...the outflows from these storms are likely to cover most of if 
not all of the area. For this expectation...will knock a few 
degrees off Saturday min temperatures that are shown to be quite warm on 
the blended guidance. Likewise...high temperatures for Saturday and also 
Sunday are slightly below the MOS guidances for the weekend. Model 
run-to-run trends show an slight increase in middle-level moisture 
and rain chances for Sunday...with the favored European model (ecmwf) trending 
toward the wetter NAM/dgex from earlier runs. Rain chances Sunday 
are mainly across the higher elevations of the Edwards Plateau and 
Hill Country. High pressure remains in place during the 
weekend...keeping temperatures hot despite the added cloud cover 
and spotty rains. The upper high is expected to strengthen back 
eastward across Texas by Monday and set US up for more oppressive 
heat through next week.
