Trader consensus on Polymarket reflects significant uncertainty in National Weather Service forecasts for Houston's high temperature on April 5, with implied probabilities peaking at 33% for 76°F or higher amid model divergences on a weekend cold front's timing and intensity. Recent NWS updates highlight scattered showers and thunderstorms likely Saturday afternoon as the front approaches from the northwest, potentially capping highs through increased cloud cover and precipitation—favoring outcomes like 70-71°F (25%) or 72-73°F (17.5%) if rain is widespread. However, if the front delays or weakens per some GFS runs, highs could push into the upper 70s, aligning with early April climatological averages around 78°F.
