National Weather Service forecasts indicate a high near 88°F for Houston on May 15 under mostly sunny skies with south winds 5-15 mph, aligning with the 86% market-implied probability for 86°F or higher as trader consensus reflects strong model agreement from recent GFS and ECMWF runs. This positioning stems from a building high-pressure ridge fostering subsidence aloft and warm advection via southerly flow, continuing the recent trend of upper-80s to low-90s daytime highs observed over the past week amid stagnant conditions prompting ozone action days on May 13-14. The May 15 climatological normal high of 87°F at Houston's Intercontinental Airport provides baseline support, though minor uncertainties like isolated clouds or gusty winds could cap peaks at 84-85°F (9.5% odds). Traders await the NWS afternoon update for refined guidance ahead of resolution based on official observations.
