NEW YORK — The final week of 2021 will feature several weak systems giving periods of light rain. The first disturbance crossing through the region Monday night will be capable of producing a bit of icing north of the city. A winter weather advisory has been posted for those areas until early Tuesday morning.
Some light rain and drizzle will cross through the region on Monday night. Across all sections, there could a few flakes flying around initially, but it will changeover to light rain or drizzle. To the north where the changeover will be slower, a few spots could get a coating before it starts to changeover to a light freezing drizzle. Amounts will be light with a glazing, but it will be enough to cause treacherous travel especially on untreated surfaces.
Any rain or icy mix should taper off before daybreak on Tuesday morning. Temperatures will gradually climb to around 40 degrees before the morning commute gets underway.
Much of Tuesday looks to be decent day. A mild westerly wind will develop briefly and skies clear out for the afternoon. Temperatures could climb toward the lower 50s in the city, while surrounding suburbs top out in the upper 40s.
Another quick-moving disturbance crosses through the region late Tuesday night. Again, some rain showers will be possible for the city and points south. For inland areas, it could be cold enough for a period of snow or a wintry mix.
Any rain, snow, or mix should taper off early on Wednesday. Clouds will stick around though as a front meanders across the region. Temperatures will be in the upper 40s.
The third and last disturbance brings another round of light rain by late Wednesday night. For most of the region, it looks to be rain as temperatures will be several degrees warmer overnight. The rain will linger through Thursday morning before it finally tapers off. Skies will then clear out with temperatures topping out at around 50.
New Year’s Eve looks to be a delightful day as high pressure crosses through the region. Expect mostly sunny skies as temperatures climb to around 50 degrees. As the clock hits midnight, temperatures will be around 40 degrees under partly cloudy skies.
As for New Year’s Day, clouds will be on the increase as a potent storm system arrives. Rain may develop in the afternoon and continue into the evening. While far from certain, additional showers will be possible through Sunday and Monday morning as well.
