Snowstorm on January 22nd, 2005


A major snowstorm developed Friday evening in response to the last in a series of potent "Clippers" dropping out of Canada into the Great Lakes.  The heaviest snowbands developed by late evening and continued well into Saturday morning as surface low pressure moving east-southeast out of Illinois intensified.  Two dominant mesoscale snowbands (Figures 1 & 2) developed in response and were responsible for the majority of the snow accumulation.

These bands resulted in the higher observed accumulations (Figure 3)...especially the first band (Figure 1) late Friday evening which produced 1 to 2 inch per hour snowfall rates...and resulted in a general 4 to 8 inch snowfall with 8 to 12 inches generally along and north of the toll road. Areas south of highway 30 received considerably less due to a pronounced dry slot which developed Friday night in response to rapid intensification of the upper level system and further northward track. The brown colors in Figure 4 show the dry mid level air wrapping around the southern periphery of the intense surface circulation denoted by the light blue L in Figure 4.

Figure 3 represents a contour map consisting of storm total snowfall reports from coop observers and snow spotters.

Figure 4 is a water vapor satellite image on the morning of January 22nd showing the dry slot moving into western Indiana. Note the developing dry slot (red) on the nose of a 150 mph jet streak (white arrow). Snowband #1 (Figure 1) had pushed into Michigan and northwest Ohio while snowband #2 (Figure 2) was rapidly developing over northwest Indiana.
