Persistent summer heat under a strong subtropical ridge continues to drive Houston temperatures toward the upper 90s to low 100s on August 26, with National Weather Service guidance centering near 98–100°F amid southwest flow and elevated dew points. Afternoon sea-breeze convergence and scattered convection introduce the main uncertainty, as timing and coverage of clouds or storms can shave several degrees from peak readings while drier pockets allow brief pushes above 100°F. This aligns with typical late-August conditions modified by the current heat dome, where small differences in boundary-layer mixing and moisture advection create the narrow spread reflected in balanced market-implied odds across the 96–103°F range. Updated model runs and official National Weather Service briefings tomorrow morning will refine the exact maximum.
