Here’s how to see archived model runs of historic storms
The Blizzard of 2006 was a tremendous snowstorm in our local area. While it did fall in the middle of a warm and otherwise uneventful winter, it featured some tremendous dynamics and impressive banding. Do you remember what forecast models were showing prior to that event? Me neither. Up until now, it’s been fairly difficult to find archived model images dating back to the mid 2000’s, and even if you accessed them, the images were coarse and the graphics difficult to comprehend.
That has changed. Unknown to some, there is an easy and simple way to access model data from the wildly popular free model data website at Penn State University. Known as “Ewall” to meteorologists and hobbyists alike, this website has been around for many years, and has served as a central hub for model data while remaining “new” to the times with upgrades and new graphics. The website also houses a freely accessible archive of model images dating back to 2004.
