Sioux City Area Report
Sioux City, Iowa topped out at 20.7" in a three day epic snowstorm.
First, our latest and (hopefully final) snowfall total:
1200 PM SNOW SIOUX CITY 42.50N 96.39W
12/26/2009 M20.7 INCH WOODBURY IA CO-OP OBSERVER
The storm began on Wednesday, December 23 with what I called "Wave 1". Wave 1 brought approximately 6" of new snowfall to the area. That night was a temporary lull.
On Christmas Eve, December 24, "Wave 2" moved in. This storm brought approximately 5" more of new snowfall, with much more wind. This was followed by yet another temporary lull.
On Christmas Day, December 25, the strongest wave, "Wave 3" moved in, with wind and heavier snow. This snowfall accumulated an additional 8" of snow.
Today, December 26, brought an additional 2 to 3" of snow to the area as wraparound moisture precipitated in additional snowfall, bringing totals to over 20" in many places.
This storm is the 3rd largest snowstorm of All Time in the Sioux City area. This is also the snowiest December ever in Sioux City history, and also the snowiest Christmas in Sioux City history.
I want to apologize for the poor photo quality. These pictures were shot with my cell phone camera. They are not the best quality but no doubt they convey the snow depth enough to get the picture.
