Midweek Storm to Soak Tuesday Night, Then Drop Temperatures and Trigger Lake-Effect Snow

A Wednesday cold front ushers in gusty winds, with a rain-to-snow shift over the Great Lakes.

Overview

  • Steady rain spreads in Tuesday evening into early Wednesday, with most areas receiving about 0.25–0.5 inches and locally near 1 inch in parts of southeastern Massachusetts and the Islands.
  • Wednesday turns milder ahead of a sharp front, then temperatures fall quickly Wednesday night into Thanksgiving as northwest winds gust 35–45 mph, with advisories posted in some regions.
  • Across the Great Lakes and nearby Midwest, rain changes to snow Wednesday, and lake-effect bands into Thanksgiving and Black Friday may cause localized visibility drops and slick travel.
  • Thanksgiving is largely dry but colder for many eastern cities, with highs in the 30s to 40s and wind chills in the teens or 20s in spots.
  • AAA projects roughly 82 million travelers for the holiday period, and forecasters are monitoring another system late Sunday that could bring additional precipitation for return travel.
