The next in the long-range weather forecast series published in The Mountain Astrologer is ready to be looked at. This is the forecast for February 13-15 and was drawn up over half a year ago in July 2011. The forecasts appeared in the Feb/Mar 2012 edition of the magazine.

February 13-15, 2012
The combined influence of Mercury conjunct Neptune, and Venus square Pluto will increase atmospheric moisture, resulting in atmospheric disturbances where these planets occupy the angles of key charts. The U.S. West Coast will see a storm system move into the Pacific Northwest and push toward the Rockies. Precipitation intensifies over the Plains states, around Iowa and Missouri, while the Northeast gets in on the storm action as well.

Cold air will funnel down through Siberia toward central China, triggering storms.

Between the 13th and 15th a number of storms moved in over the Pacific Northwest and California. The Accuweather map below for the 13th shows what is called an "inside slider" or storm system that slides into California from the northwest focusing its energy over the Sierra Nevada and Great Basin.
