The Oregon Chapter of the American Meteorological Society hosted the 20th annual Winter Weather Forecast Conference on Saturday, November 17th 2012 at 10 AM. Meteorologists from across the Pacific Northwest once again descended on OMSI in Portland to give their prognostications for the upcoming winter in front of more than 300 attendees. The consensus amongst the majority of forecasters was that El Nino and La Nina will not be large factors this winter. That leaves the door wide open for a wide array of weather across the Pacific Northwest over the next few months. It was also noted that Portland has recorded plenty of cold and snowy weather in years where neither El Nino or La Nina were present.

Below is a complete wrap up of the days events, including a video of the entire meeting. You can also download each forecasters presentation.

 

The conference opened with a welcome by Steve Pierce, Oregon Chapter President that transitioned into a science year in review by Jim Todd, OMSI Planetarium Manager.
