First Winter Storm of 2007! (1/15/2007)

By: Robb Lawson

While the first winter storm of 2007 did not produce significant snowfall amounts, it did bring unusually large amounts of sleet.

The stage was set for this event as very cold arctic air filtered into the area during the early morning hours of Friday January 12th. Once this cold air was firmly in place, a series of upper level disturbances tracked out of the desert southwest and into the southern plains. The first round of wintry precipitation started Friday over Southeast Kansas with the remainder of the area getting in on the action Saturday January 13 and Sunday January 14th.

Even though it was plenty cold at the surface for snow, a layer of warm air aloft allowed the ice crystals to melt on the way down, and then refreeze right before hitting the ground. This is why the majority of the precipitation during this event fell as sleet. Southeast Kansas was hardest hit with some locations picking-up 3 inches of sleet. Please see image 1 for a map showing sleet amounts.
