Pacific Northwest snowpack improves at the start of March after week of snow
A prolonged pattern of upper level troughing and repeated regional storm systems have added quite a bit of snow to mountains of the Pacific Northwest over the past week.

We need to close the Pacific Northwest Radar Gaps
Doppler radar is one of my favorite tools for viewing weather data. Its amazing to me that using radio waves, we can see light rain and snow, tornadoes, and fine details in hurricanes. Not only can we see where these are, but we can also estimate wind speeds, freezing levels, and hail sizes – all […]
Warm system for Thanksgiving week
An atmospheric river is set up to douse almost the entire West Coast. Raising freezing levels today and tomorrow will aid Thanksgiving travelers the next couple of days, keeping snow off of the major passes.
