SUMMARY:

The weather pattern this January was much like 2005, which had a very mild, wet first half
then a colder, drier and snowier second half.  13 of the first 16 days had highs above
freezing, while only 1 of the last 15 days reached above freezing.  The seasonable to below
normal temperatures of the second half didn't quite offset the warmth of the first half.
Most of the precipitation prior to the 16th fell as rain, while nearly all precipitation
after the 16th was snow, which fell almost continuously due to a persistent west to
northwest flow off the great lakes and ridges.  All of the last 12 days had measurable snow,
and 27 of 31 days had measurable precipitation, which is most likely a record for any month!
