The National Weather Service has issued a winter weather advisory for the Berkshires. The advisory is in effect from 10 pm tonight to Noon tomorrow.

A mixture of brief snow, sleet and freezing rain is expected to cause slippery road conditions across much of Western Massachusetts tonight.

The wintry mix is not expected to leave much accumulation but could cause treacherous driving conditions, according to the NWS.

"A Winter Weather Advisory means that periods of snow, sleet or freezing rain will cause travel difficulties," the NWS said. "Expect slippery roads and limited visibilities, and use caution while driving."
