Snowy December may lead to January thaw problems

December 27, 2010

A warm November has given way to a cold and snowy December, resulting in 14.0″ of snow through December 26. With over an inch of water locked in the ice, upcoming forecasts for temperatures near 50 degrees and thunderstorms point towards the potential for flooding.

With the ground frozen after single digit nights, any precipitation and snowmelt will immediately convert to runoff. If the combined amount exceeds 3″, flooding is likely.

Currently, 1.12″ of water is locked into our 8″-deep snowpack.

This situation should be monitored as warm air runs into the area on Thursday, followed by strong thunderstorms and a sharp cold front on Friday. Standing water may freeze on Saturday.
