Once again the long range model forecasts indicate that the region is going to enter a period of dry and unseasonably mild weather the remainder of October. The storm track will shift back to the north across Canada.  This is quite obvious from the model forecast for next Sunday.  The upper high is located near Wyoming.

This results in a period of Indian Summer across much of the west.  By definition :

An Indian summer is a name often used to describe a warm, calm spell of weather that occurs in autumn. … The Met Office Meteorological Glossary first published in 1916, defines an Indian summer as ‘a warm, calm spell of weather occurring in autumn, especially in October and November.

 

Such is the cast this year.  The forecast for total precipitation for the coming  week clearly shows the dry period ahead
