After a beautiful day today, a weak wave passes to our north on Friday, increasing clouds but likely yielding no or very light precipitation.
A second wave takes a far more western track and digs southward off the coast of California, pumping up a ridge over the Great Basin that should yield dry and warm seasonal temperatures through Monday.
The evolution of the the trough off the west coast will determine our weather mid-week, and models are struggling with the details. Currently, some energy is forecast to split from this digging wave off the coast and travel over the ridge before bringing cold air southward along the Front Range on Tuesday. Concurrently, some energy is ejected from the trough and travels over us late Wenesday or early Thursday, producing light precipitation.
Models are in disagreement with the pattern after this with regards to the trough of the west coast, with one keeping most of the energy off the coast and the other bringing it inland.
