Recent National Weather Service forecasts indicate a strong cold front has swept through central Texas, shifting Austin from southerly flow and highs near 90°F to northerly winds gusting 20–40 mph and daytime highs in the upper 60s on October 17. Clear skies and reduced humidity overnight will promote radiational cooling, with model consensus pointing to a minimum near 46–50°F. This places the outcome near the boundary between the closely matched 41°F-or-below (49.5%) and 60°F-or-higher (48.5%) market-implied probabilities, as small differences in wind speed, cloud cover, or dewpoint can shift the low by several degrees. Updated model runs and official briefings over the next 48 hours will refine the exact threshold.
