.KEY MESSAGES...
- Temperature remain at or just above normal through the forecast period.
&&
.SHORT TERM (THROUGH SATURDAY)... The mid and upper level subtropical high from northern Mexico into the southern U.S. plains will remain in place through the upcoming weekend. This will result in a continuation of temperatures remaining at or above normal along with mostly dry weather for south central Texas. The exception will be across portions of the coastal plains westward to the Rio Grande where some isolated convection may develop today and again on Saturday.
&&
.LONG TERM (SATURDAY NIGHT THROUGH THURSDAY)... As we head into early next week, the medium range models show an upper level trough axis moving through the southern Rockies into the central plains states. This may serve to temporarily weaken the subtropical ridge axis over the southern plains. However, we don`t expect to see any significant change in our sensible weather through the remainder of the forecast period. Little spread is noted among the operational and ensemble guidance with respect to temperatures. Highs will generally range from the mid 80s to the mid 90s along with lows in the mid 60s to lower 70s. Any opportunities for rain will remain scarce and primarily confined to the coastal plains westward to near the Rio Grande where moisture levels may be sufficient to support some isolated convection.
&&
.AVIATION (06Z FRIDAY THROUGH SATURDAY)... MVFR ceilings are possible yet again overnight into the mid-morning hours Friday, particularly at SAT, SSF, and DRT. DRT stands the best chance at MVFR ceilings with prevailing group utilized between 12- 15Z. TEMPO groups were considered at SAT and SSF but held off for now and will reevaluate at the 09Z Amendments. Otherwise, VFR ceilings are expected through the period along with increasing winds of 9-12 kts.
