Winter Storm Watch Long Island Southern New England
Snow Monday Night
Winter Storm Watch is up from East of NYC to Boston and covers Long Island and all of Connecticut. The map above shows the National Weather Service snow forecasts that were update late this afternoon. For areas in Eastern Pennsylvania and New Jersey it looks like a 2 to 4 inch snowfall with the highest amounts in the Northwest and along the North Jersey coast. To the east across Long Island and Connecticut amounts go up to 6 to 10 inches and even higher in Southeastern New England.
If models trend a bit further to the west overnight we could see watches extended westward but for now this seems to be a fair assessment of what should happen with this storm. This is third noreaster in 10 days to effect the area. Of the 3 storms this will probably have a smallest impact over the smallest geographic area however it will bring heavier snows to the coast which in general saw less snow than in the last storm. There are no weather issues tonight or most of Monday with clear skies tonight and arriving clouds on Monday. Lows tonight will be in the mid 20s to lower 30s and highs Monday will be in the 40s.
The regional radar is beginning to show rain to the south which is the leading edge of the developing secondary low. That low at the moment is moving across the Gulf States. Northern energy with this is driving southeastward into the Tennessee Valley at the moment and you can evidence of that in the twist of clouds on the satellite picture moving into Tennessee.
Snow arrives tomorrow night and ends during Tuesday morning. Since most of the snow falls at night it will stick with temperatures close to freezing. Snow will be heaviest along the coast. We should see improving weather conditions Tuesday afternoon with leftover clouds and some developing sunshine.
With regards to winds and coastal flooding we should see gales developing along the coast Monday night into Tuesday morning. Winds will be bending around to the north and northwest so coastal flooding impacts should be mitigated somewhat. The new moon is not until Thursday which helps. Hopefully this will be the last nor’easter as the blocking pattern across Northeastern Canada begins to weaken and break down.
As far as final snow amounts are concerned 60 miles here will make all the difference. If the storm shifts in either direction, look for snow amounts to shift with it. Further east shift means less…further west means more, especially west of the coast.
