A code green winter weather advisory in effect for extreme Southern NJ and Delaware for Sunday December 18th, with potential for a small snow event, this will most likely remain south of even these areas but something to watch for, confidence is low (not likely but wanted to put is out there)
A code green winter weather advisory in effect for I95 and points NW for Tuesday-Wedesday December 20-21. This means there is a chance of a minor winter storm within the next 7 days, but confidence is low at this time. (this has potential and is something to watch)
For today, it will be partly sunny and highs around 45 and winds shifting from NE to SE ahead of an approaching weak warm front
Tonight will become overcast with lows in the mid 30s
Thursday there will be a slight chance of showers in the AM gradually increasing through the day with highs 50-55 ahead of the cold front under a SW wind
Showers will end Thursday night and polar air will invade once again with lows in the lower 30s
Friday, im looking for sunny skies, a cold NW wind and highs 40-45 degrees
Friday night lows fall back to levels we saw this past weekend, with lows 18-25 expected in the suburbs and 25-30 over urban areas
Saturday most of us will be stuck in the mid to upper 30s besides those urban and coastal locations that may break 40 lows again 18-25 expected 25-29 for urban areas, clear skies
Sunday could be interesting for our southern areas, as the cold front from Thursday stalls south of us, a weak disturbance will ride along this front, and depending on where it stalls, extreme southern NJ could get a light snow event. For the rest of us it will just be a mostly cloudy and cold day with highs again in the upper 30s to around 40 lows 20-25 to around 30 in urban areas. Right now this disturbance could very well track south of these regions too.
Monday the cold air isn’t going anywhere, a polar front will come and potentially stall south of us, the exact placement of this front will make the difference of whether we see a rainstorm, a slop storm(mix) or a snowstorm next Tuesday and Wednesday
It looks like an area of low pressure will develop along this front, and wherever the front stalls out is where the storm will track. If it stalls say over Delaware, Northern NJ and NYC would possibly get a snow event. If it stalls over Northern or Central NJ the snow shifts north and we get mainly rain. It will all come down to where this front stalls, and that will be determined by how strong the SE ridge is and how far south the Polar Vortex up in Canada comes.
Right now I like the idea of more of a sloppy mixed bag type of storm, like rain changing to snow or snow changing to rain or both mixed together but confidence is low at this time , ita almost a week out and no details can be determined yet
Some models have an early phase of the jet streams and goes into the Great lakes (not likely but possible) This would mean all rain
Others have the front stalled over Delaware and snow event and some actually have nothing at all, so clearly the models are no help. Based on what I see I like the front stalling over southern NJ with light to moderate winter storm possible, again details will be ironed out this weekend when we have a better idea.
Another storm may be brewing for the Christmas Eve/Christmas holiday also , a very active pattern is on the way, and travel for the holidays could be greatly impacted, more on these storms to come in the upcoming days!!
