Issued prior to a Winter Storm Watch. The Outlook is given when forecasters believe winter storm conditions are possible and are usually issued 48 to 60 hours in advance of a winter storm. A Lake Effect Snow Advisory also cautions for the possibility of snow. No accumulation or light dusting is all that is expected. Snow falling at varying intensities for brief periods of time.
Some accumulation is possible.
Brief, intense snow showers accompanied by strong, gusty winds. Accumulation may be significant. Snow squalls are best known in the Great Lakes region. Wind-driven snow that reduces visibility and causes significant drifting. Rain drops that freeze into ice pellets before reaching the ground.
