National Weather Service and private forecasts project a high near 101–103°F for Austin on August 16 under mostly sunny skies and light southerly flow, consistent with the subtropical ridge that typically dominates central Texas in mid-August. This range aligns with climatological norms, where daily maxima average in the mid- to upper 90s but frequently reach the low 100s amid high humidity and heat indices above 105°F. Recent model runs show minimal spread, with only slight differences in afternoon mixing or cloud cover that could nudge the peak by a degree or two. Traders have priced the 100–103°F bins highest, reflecting the strong consensus from official guidance while acknowledging residual uncertainty from local microclimates and final observational adjustments.
