A dynamic mid-latitude cyclone tracks near the New England coast today. Scattered showers and thunderstorms spread into the East Coast today. A swath of moderate to heavy snowfall is likely to develop across portions of the interior Northeast -- winter storm watches and warnings are in effect for portions of central New England related to the heavy snow threat. Elsewhere, Lake Effect snow showers across the Upper Great Lakes may yield anywhere from 4-8 inches over the northern coastline of the Upper Peninsula of Michigan as well as northern parts of the Lower Peninsula today. A disturbance aloft will allow for the development of a new cold front late today which moves east and south ahead of a strong and cold surface high. In the wake of this front, as temperatures cool further, lake effect snows should expand and intensify as they interact with record warm Great Lakes temperatures for late November. Several additional inches of snow are forecast on Friday bringing 2 day snowfall totals over a foot with isolated higher amounts possible across downwind areas of the Great Lakes by Saturday morning. Florida will remain mild to warm. Kebede/Roth Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
