Wednesday Evening the 17th.

The global models are making the change to a warmer pattern beginning this weekend and next week in Mammoth with a strengthening Continental Upper High, retrograding further west. Expect an increase of precipitable water early next week.  The Owens Valley will become more humid with a chance of thunderstorms beginning Tuesday.

The flow becomes southerly in both the EC and GFS early next week which is not the most favorable pattern for thunderstorms in Mammoth. Nevertheless, isolated showers and thunderstorm will develop as early as Sunday, especially areas along the Mono County convergence zone. Areal coverage will increase through mid week next week. Most favorable upper flow for Mammoth is Southeast flow.  So there will be an increase in convection, but mostly areas east, north and southeast of Mammoth Lakes.

Our best chances of Showers and Thunderstorms will develop this Tuesday into Wednesday in town. Should the models become more favorable with SE flow, later next week, the odds will increase for better wetting rains here.
