minmax

the house always priced weather off a real model. you had a weather app. that gap was the whole game. the desks settling temperature markets ran physics. you ran "feels like 78°." they were never guessing. you always were. today that ends with minmax pro — and the edge is already live. denver: a thunderstorm 200 km west. our outflow detector has flagged the cold pool — about −5°F landing in an hour. the crowd is still pricing yesterday's number. the model already moved. new york, same day: public forecast says 78°. our model says 81°. the 81° bucket sits at 0.05 because nobody sees it coming. it settles 81°. 0.05 → 1.00 = 20×. illustrative — but the temperature matched our model, not the market. on temperature markets the best forecast wins. sharper than the crowd = mispriced buckets you can take. that is the whole game. here is what is reading the sky for you. say it plainly: a hybrid ml system forecasting temperature at the 11 largest us airports — chicago, atlanta, miami, houston, denver, seattle, san francisco, los angeles, new york, dallas, austin — every horizon from 1 to 24 hours out. not one model. a stack. · base ensemble → 3 lightgbm models (synoptic · convective · base) blended with per-hour-per-horizon weights · detector-boosters → 24 specialist experts per airport, each trained on one phenomenon — front (the sharp swing) · cloud (solar heating blocked) · fog (the morning stall) · outflow (a distant storm's cold pool crashing in) · heuristic physical correctors on the short horizons h+1..h+6 24 detector-experts. per airport. one knows a front passing. one knows shadow cooling as cloud builds. one knows fog and the minute it burns off. one watches a storm 200 km west and knows its outflow lands in an hour and pulls the temp down ~5°F. minmax
