Discussion
An Arctic air mass has arrived in the I-95 corridor and temperatures have already peaked for the day and will drop into the 30's as the day progresses. Rain associated with the arrival of the Arctic front may change briefly to snow before the precipitation winds down - watch for "black ice" later in the day as temperatures near the freezing mark. By late tonight, temperatures could be in record low territory in the upper teens - way below-normal for the middle of November. Temperatures on Wednesday will struggle to pass the freezing mark for highs which may turn out to be the "lowest" high temperature ever recorded for the date.
