Persistent heat under a strong upper-level ridge and mostly sunny skies with light winds is positioning the National Weather Service forecast for Austin-Bergstrom International Airport at 102–105°F on August 21, aligning closely with the market’s leading 102–103°F (59.5%) and 104–105°F (30.0%) bins. Recent model runs show minimal day-to-day variation amid a multi-week stretch of triple-digit highs, while ensemble spread and typical late-August variability introduce modest uncertainty around exact peak readings. Official observations from prior days near 103°F reinforce trader consensus on these central outcomes, with resolution tied to the verified daily maximum at the airport station.
