How? the models are calling for a stall so how do you throw them out then? and why don't you buy it?
...It's probably not so much a question of if it will stall, but where... It may stall as the models indicate, but the analysis that I have demonstrated shows at least for one model, the GFDL, it was off at its 6 hour interval with a SSW bias. Extrapolating the 18z GFDL is already thrown out for that reason.
