Threat switches from snow to freezing drizzle – Winter Weather Advisory in effect

Snow has moved out of the region this morning except for some flurries in some parts of the Mid-South. As the main weather system departs, another less potent one will swing by to our north over the next 24-30 hours. Much of the mid and upper-level moisture is departing with the overnight weather system, leaving only low-level moisture to work with. Thus the threat has shifted to freezing drizzle.

The Winter Storm Warning has been downgraded to a Winter Weather Advisory, effective until noon Tuesday for the entire Mid-South. Though amounts are expected to be very light, driving conditions could actually worsen as freezing drizzle could leave a very light glaze of ice behind. From the National Weather Service in Memphis:
