In addition to the heavy rain and milder conditions, winds will become a very important factor on Thursday night and early Friday with the potential of gusts of 50+ mph across inland locations and 70+ mph along coastal sections.  Winds in the lower part of the atmosphere will reach excessive levels tomorrow night – just ahead of the strong cold front – and it won’t take much in the way of “mixing” to bring these winds down to surface levels. In fact, one of the mechanisms that can result in damaging wind gusts will be strong thunderstorm activity that is likely to develop along the frontal system from later tomorrow into the early morning hours on Friday.  Unfortunately, these kind of gusts will raise the chances for power outages later tomorrow night and early Friday in the Mid-Atlantic/NE US.

Behind the strong cold front, temperatures are likely to crash on Friday in the I-95 corridor from their early days highs in the 40’s and 50’s to late day readings in the 20’s.  This rapid drop in temperatures following the passage of the cold front could result in a quick ice-up of any leftover standing water on untreated surfaces. There is the chance on Friday for a few snow showers in the I-95 corridor as the colder air pours into the region.  The rain will change to accumulating snow later tomorrow across portions of the Ohio Valley such as eastern Ohio and in the western part of the Mid-Atlantic/NE US from West Virginia to western Pennsylvania to western New York State. High pressure takes control on Friday night and the weekend will start off quite cold with temperatures on Saturday struggling to reach the freezing mark in the I-95 corridor region from DC-to-Philly-to-NYC.
