The market's 62-63°F band is too restrictive. Our analysis projects a strong NO. The GFS 12z and ECMWF operational runs show a persistent 500mb trough axis to the east, maintaining robust post-frontal cold air advection from a surface high over the Ark-La-Tex. While morning lows will be suppressed, the NAM 00z run, combined with high-res deterministic models, indicates rapid clearing and significant solar insolation by afternoon. This will drive boundary layer mixing. The GEFS ensemble mean for HOU's high on May 5th is 64°F, with the 75th percentile extending to 66°F. Only the extreme lower tails of the ensemble spread touch 62°F. The core probability distribution, factoring in efficient solar heating, places the high just above the market's upper bound. Sentiment: While some local forecasts emphasize the unusually cool temps, the precise quantitative models indicate an overshoot. 90% NO — invalid if the GFS 18z ensemble mean drops below 63°F.
