San Juan Mountains Weather Forecast ~ Friday, June 15, 2018 @ 13:30

As tropical storm BUD spins it’s way north in the Sea of Cortez it’s copious moisture is being drawn into the desert southwest by a large low-pressure trough originating  in the Pacific northwest.  The trough’s counter clockwise spin is drawing in BUD’s energy and up to 1.3″ precipitable water has been measured.  When the disturbance moves into the San Juan later tonight and tomorrow we could see some good rains, lightning and flash flooding near the Durango burn areas.  Might get ugly if all this activity works in syncronicity.

Some satellite photos and vorticity/ precipitation  maps below.
