The upper low from the winter storm a few days ago simply will not quit.  I’m about to call this storm, Rocky Balboa as every time you think it is finished, the storm gets back up for another round.

Luckily the next round of this storm will be focused well to the north and east of the northern Mid Atlantic as the upper low currently over eastern Pennsylvania will capture a Sub Tropical disturbance over the Gulf Stream.  The Sub Tropical disturbance will intensify into a very nasty winter storm for northern New England and the Canadian Maritimes through tomorrow.  The influence of additional Atlantic moisture into the upper level low will aid in keeping widely scattered snow showers in the region through this evening.  However, no significant accumulation is expected with these snow showers as surface temperatures rise into the upper 30′s to around 40 degrees for afternoon highs.

The upper low will finally move to the east of the northern Mid Atlantic tonight, bringing about a northwesterly flow and drier conditions to much of the Mid Atlantic for tonight through Tuesday.  High pressure will take hold at the surface with temperatures return to near normal levels.  High temperatures in the mid 30′s to lower 40′s throughout the region will support a steady melting of the snow pack through the day and a refreeze at night, prompting the threat of black ice each morning, so use caution.

Another winter storm threat is materializing for late Tuesday night into Wednesday morning.  At this time, the most significant impacts from this coastal low will remain well south and west of the region.  However, some moderate snow accumulations, especially over southern/central New Jersey is possible.  This time of year, not only is the track but also the timing of the heaviest precipitation will be key for determining accumulation potential.  Due to the higher sun angle and the marginal boundary layer temperatures, snow may fly on Wednesday morning, but the actual accumulation of that snow may be significant limited.  Otherwise, this storm is not in any way looking as significant as the storms experienced through much of February.

High pressure returns for Thursday through Saturday with dry conditions and moderating temperatures in the 40′s.  Any snow that is left from the previous winter storm will be melting rapidly as a more Pacific air mass influence is felt throughout the nation.
