Today's observed high so far from the airport METAR station (public-domain source, spike-filtered), plus a past-peak signal. Observed facts and inferred judgement are returned as separate fields, and the inference ships with its own measured accuracy (0.984 over 61 out-of-sample days) and a named failure mode, so you can weight it rather than trust it blindly.
