From the forecast discussion:
A developing trough will approach the west coast by tuesday. The
Models have some differences with the evolution of this
System...As the gfs shows a wetter more progressive solution for
Central california...Swinging the trough inland tuesday. This
Will bring cooler temperatures and chances for precipitation to
All of our forecast zones tuesday. The ecmwf splits the trough
With the southern part forming a closed low which remains
Offshore and drops south...Keeping precipitation chances very
Minimal over our area. The forecast at this time continues to lean
Toward the wetter gfs solution but confidence is low.
For the remainder of next week...Models trend back toward
Moderate agreement in rebuilding a ridge across the region. This
Will provide dry conditions with temperatures warming back to a
Few to several degrees above seasonal averages.
