Offshore Low Throws Back Snow Southeast New England to Perhaps Eastern Long Island
This is about as close as it has gotten for snow in the Coastal Northeast. Friday’s cold front stalled out well offshore and along that boundary a new storm has formed and it is sitting well east of Virginia this morning and not moving anywhere fast. It is far enough offshore to miss areas from Southern New England to the Delaware coast but the northward drift is pulling back precipitation westward and it is backing into Southeastern New England. We could see anywhere from a coating to a few inches there and the snow could back its way into Eastern Long Island and the satellite and radar show clearly how close this storm is.
Meanwhile for much of Eastern Pennsylvania to Southern New England it will be a cold day. Sky conditions will range from partly sunny to the west to mostly cloudy along the coast with a gusty north wind and temperatures today that should reach the upper 30s and lower 40s. Yesterday we saw snow showers that were around the area but we are not seeing them on the radar today though we do see the western edge of the offshore storm’s precipitation shield close to Eastern Long Island.
This storm is going to move out to the east and then turn north and northwestward over the next couple of days and that keeps the threat for snow from Maine to Southeastern Massachusetts through Monday night. It also takes up space leaving very little room for the next storm system and cold that that is coming in from the west. That system will reach its peak strength later Monday before it runs into the the storm to the east near Nova Scotia and begins to weakens to slow down and weaken.
Between the two systems tonight skies should be partly to mostly clear with more clouds over areas to the east from Southeastern and Southern New England to perhaps Central and Eastern Long Island. Most lows will be in the 20s except lower 30s warmer urban areas. Let’s call Monday mostly cloudy east to partly sunny west and highs will be into the 40s.
The next cold front approaches Tuesday while the storm to the east is still sitting near or south of Nova Scotia and east into the Gulf of Maine. This system dominates the scene and the the western system gradually weakens and falls apart. Still we will see clouds Tuesday and there could be a few rain showers around Tuesday into very early Wednesday morning but it won’t amount to much. Tuesday highs will be in the 40s to around 50. Those showers will be scattered around and it is possible that not many folks see rain from this.
After this weak front goes by and the storm to the east finally pulls away, weather systems will continue to move along and they are really going to able to develop much. Nor is there much of any cold air behind these fronts as they go by. This should leave us dry with a mix of sun and clouds with highs in the 40s but that dry weather will be short lived as the next system arrives with some rain or showers Wednesday night into Thursday.
Here too we don’t expect much development of this low as the primary low reaches the Ohio Valley and then translates its way eastward Thursday night and Friday. Once the main shot of rain is done early Thursday, we will probably sit in clouds and some showers on and off later Thursday into Friday until this system finally moves out to the east. Temperatures Thursday and Friday will be in the 40s. There is an outside chance for a little snow mixed in over elevated areas later Thursday into early Friday but it isn’t much and it’s not going to evolve into anything substantial. We don’t see any substantial changes in the overall pattern in the East over the next 10 days. The pattern in the west is changing as the Pacific fire hose jet stream pattern breaks down and the storm after storm pattern finally comes to an end. However we don’t see much change in the Eastern US with no reall connection to cold air in Canada. That may come at the end of the month but for now it is more of this non-winter winter.
