Does another heat wave follow the current episode for next weekend? ECMWF says yes and forecasts a stronger event than currently taking place. The GFS is not nearly as hot. The question is whether the hot air source region in the Central U.S. pulses eastward (or not). GFS says no while ECM is (vigorously) yes! The precedent is set as last week’s Midwest heat wave has shifted into the East now. A second event is likely and given peak summer heat the next event could be hotter.
