Vermont Lake Effect Snow Develops In Champlain Valley; Up to 6 Inches Snow Possible

National Weather Service radar this morning showed
two lake effect snow bands coming off of Lake 
Champlain. One was hitting an area in and around
Colchester and Milton, while another stronger one
was in southern Chittenden County and 
in Addison County. 
 As mentioned in a post earlier today, it's still snowing a little across Vermont. 

But in the Champlain Valley of Vermont, especially in Addison County and the southern half of Chittenden County, something of a lake effect snowstorm has blossomed this morning. A winter weather advisory has been issued or those two counties. 

Areas along the Route 7 corridor from near the shores of the lake to the western slopes of the Green Mountains in this area can expect a storm total of up to six inches of snow.

There was actually two  snow bands coming off Lake Champlain this morning. One, was coming in from east of Grand Isle into Milton, Colchester and Burlington  

The second, stronger band was focusing on places like Charlotte, Shelburne and Ferrisburgh and nearby areas. 

So far 5.7 inches of snow had fallen at the National Weather Service office in South Burlington,  as of mid-morning and I'd say half or more of that was lake effect. 

These  pales in comparison to some of those epic storms you see off the Great Lakes. But it does show Lake Champlain is capable of creating its own little snowstorms.  Especially after a warm autumn when the contrast between lake and water temperature is great, and there's no ice on the lake.

Drier air moving in this afternoon should weaken and eventually end these snow bands.
