Snow Likely Inland Later Sunday into Sunday Night,
Another Storm System Late Next Week
We will be seeing snow later Sunday into early Monday morning and this will be the first accumulating snow for many areas. The areas likely to see snow will be north of Route 78 in New Jersey with accumulating snow north of Route 80. In NYS state it will be north of 287 with accumulating snows north of Route 84. That extends into Connecticut as well. South of those areas, Long Island, Central and Southern New Jersey, Southeastern Pennsylvania this is going to be mostly a rain event.
There are no issues for today. To the east we have a developing coastal storm that is south of Nova Scotia. To the west we have some clouds moving into the Great Lakes and Ohio. In between high pressure is wedged southward from Southeastern Canada. This will be a day of sunshine and chilly highs reaching the upper 30s and lower 40s. Some high clouds could move in late in the day and they will start to slowly increase overnight. Sunday morning lows will be in the 20s inland and low to mid 30s coast and warmer urban areas.
Sunday we look for snow to develop in areas where it is cold enought, North of Route 80 in New Jersey and north of Route 287 in NY state. This will spread into Connecticut as well. Start up time will be from around 9am in Eastern Pennsylvania and the Catskills to early afternoon in Western Connecticut and then spreading further east from there. Sunday temperature highs will be close to 40 near the coast but mostly 30s inland.
Along the coast there is an outside chance around NYC and Long Island that we could see a mix or a change to snow before it ends but for now accumulating snows will stay just to the north and northwest. This should continue into early Monday morning and it should be mostly done by daybreak in most areas. Weather conditions improve afterwards with clouds giving way to some sunshine and highs Monday will be in the mid 30 inland to around or just over 40 near the coast.
The blocking pattern continues all week and that makes things complicated. Tuesday and Wednesday are the easy part as both days will be dry and chilly with highs in the upper 30s and lower 40s. Meanwhile a strong storm in the Plains which will bring blizzard conditions to the Dakotas and severe weather to the Mississippi Valley will be forced eastward under the block. This will likely bring a developing low to the Northeast and Mid Atlantic states for Thursday into Friday. All the models show this in some form or another so we will be watching this pattern evolve closely over the next few days.
