Storm cycle ends 11/10

Tomer’s Take:

  • Final storm system of this storm cycle now moving through California. Next stop is the Intermountain West.
  • Powerful jet streak, orographics, and very weak atmospheric river (AR) contribution.
  • Storm cycle ends 11/10. What happens after? High pressure rebuilds until 11/13 then a dry trough rotates through the West.
