Mexico City's late April climatological average high is ~27-28°C, making 25°C a significant negative thermal anomaly. Persistent upper-air ridging and intensified urban heat island effects routinely push maximum temperatures well above this threshold. Expecting strong solar insolation with minimal advection of cooler air masses. Current medium-range ensemble guidance models indicate high confidence in maximums exceeding 25°C. 95% NO — invalid if a strong, unforecasted cold-front intrusion manifests.
April 28 climatology shows CDMX mean highs near 27°C. GFS ensembles project robust boundary layer heating, reinforcing a thermal ridge. Insolation will amplify surface warming. The 25°C threshold is too conservative. 90% YES — invalid if unexpected persistent cloud cover.
