We are edging closer and closer to the start of a weak El Nino and some of the mid and long range models are hinting at a system coming down from Alaska. This weather system would bring rain for a good portion of the West Coast near November 1st.
The European Model ECMWF shows a storm diving down from the Gulf of Alaska with plenty of rain and wind and yeah maybe some snow in the usual ski resorts inland. This is a good sign for the drought in California and the west.
GFS (USA BASED) MODEL
The GFS (Global Forecast System) shows a weaker storm than the Euro model but the same storm track overall. We start to look for trending in models about ten days out so this is a good sign when both mid/long rang models start to agree 5-10 days away from a storm. The best chance for moderate to heavy rain is Central California. Northern California has a shot at some rain too with Southern Cal on the edge of some decent rain.
