TODAY'S DISCUSSION

After light snow this morning, clouds cleared relatively quickly 
and a milky sky has dominated ever since. Wind speeds this morning 
were very slow as the hour from 5 A.M. to 6 A.M. averaged only 1 MPH! 
Since that 1 MPH early this morning, wind speeds have moderated to 
around 6 MPH and will likely increase later this afternoon.

At 7 A.M. this morning, 0.5 inches of snow was measured on the ground, 
which amounted to 0.03 inches liquid equivalent. Shortly after 7:00 
A.M., the last of the snow ended and an additional 0.02 inches of snow 
fell, which amounted to 0.01 inches of liquid equivalent.

The record low minimum temperature for tomorrow, 1/18, is 9F set 1977.
