Monday morning will feature a mixed bag of precipitation across southern portions of the coverage area leading to some light snowfall accumulations. Temperatures will be marginal so that will limit accumulations. 1-3” is possible in southern New Jersey during the early hours of Monday. It will be a seasonable average day with highs in the low to mid 30s. The sun will likely not break out due to the developing low pressure to the south which is bringing the snow to the Mid-Atlantic regions. Overnight lows will bottom out in the low 20s in northern Connecticut to just a tick above freezing in southern New Jersey.
Tuesday is going to be a wintry mess for almost all of the area. I wrote a detailed blog speaking about the potential and my thoughts on the storm. To read that click here. Another blog that goes further in depth will be posted tomorrow. Snowfall totals will be higher the further north you go with Philadelphia expecting around an inch or so, New York City 2-4” with Boston seeing 4-7” of snow. High temperatures will struggle to get above freezing for those north and west of I-95. For areas south and closer to the coast expect daytime highs of 35-40 degrees F. Precipitation should start as snow for most before going to sleet and then rain. Precipitation should last all day Tuesday into Tuesday night. Overnight temperatures should actually be higher than daytime highs ranging from the mid 30s up north to mid 40s further south. Attached below is my snowfall forecast for the storm as well as a storm overiew!
Precipitation should be winding down for many on Wednesday morning. Philadelphia and NYC should remain dry after 4am or so with rain finishing in Boston soon after. As our low departs and strengthens it will create a tight pressure gradient and winds will whip for most of the area. I expect a few wind advisories to go up especially along the coast as gusts could approach 50mph in some locations. Daytime highs will top out in the mid 30s for nearly all of the area. There should be some peaks of sun especially during the afternoon hours. Low temperatures will hover in the mid to upper 20s and low 30s with no precipitation expected overnight.
Thursday will feature seasonally warm temperatures with highs approaching 50 in Philadelphia, mid 40s in New York City and low 40s in Boston. No precipitation is expected besides a spot shower or flurry further north. It will be partly to mostly cloudy for the whole region. Nighttime lows will be right around freezing for most with temperatures nearing the 40 degree mark further south. There may be a sprinkle or shower overnight especially in southern portions of the area.
Rain is expected to develop Friday from south to north during the afternoon and evening hours. It will not be particularly heavy until the overnight hours. It will be another mild day with high temperatures running about 10 degrees above normal for this time of year. Nighttime lows will be right around the same temperature as the highs. Rain is expected to last overnight Friday.
