SUMMARY:

Persistent cold dominated the weather pattern in February, with a slight moderating
trend towards the end.  The 3 and 4 F readings on the 5th and 6th were the coldest
February readings since 1996 when the thermometer dropped below zero.  This turned
out to be the coldest February in 16 years of record.  Meanwhile, precipitation was
slightly below normal, with most of it coming from two storms, one on Valentine's
Day and the other on the 25th.  Snowfall was above normal, and much of it also came
from these two major winter storms.
