The first widespread accumulating snow and ice particularly for interior Southern New England and possibly some coastal areas is still expected late Thursday Afternoon into Friday Morning. The headlines depict the latest thinking. Key items to be resolved remains that there is a warm layer of air between the cold surface and colder temperatures aloft. Various factors in how thick this temperature layer is, how cold temperatures are and how heavy the precipitation is will determine how much snow versus ice falls and where the rain-snow line sets up before the rain-snow line eventually moves through Southern New England changing precipitation to ice and rain. The headline changes reflect the latest thinking

SKYWARN Self-Activation will monitor the storm with potential Amateur Radio call-up nets on various SKYWARN frequencies for snow and ice totals and changeover in precipitation types and any tree and wire damage from snow and ice during Thursday Night and again for final totals and reports Friday Morning.
