East Winds Blowing On Schedule


Strong east winds set in here at house before sunrise, much as forecast by the early WRF on Monday. I estimate gusts here to around 35 mph at this time (5:40 am MST, May 14th). I have posted two versions of the 5 am MesoWest surface plots. Above covers southeast Arizona and below is zoomed on the Tucson metro area. Strongest gusts on the plots are at Muleshoe Ranch RAWS station at this time. The winds are highly variable at this time with some spots nearly calm, particularly downwind of the highest mountains - as per Tortolita and Oro Valley. Yesterday's morning run of the WRF-NAM at Atmo was forecasting these sheltered corridors quite well.
