We hope everyone had a great Thanksgiving! Today provided a chilly day for all of the Black Friday shoppers, though the airmass will be moderating over the next few days, before a cold front swings through on Monday night.
Tonight will be very chilly as high pressure slides just to our south tonight. With clear skies and diminishing winds, temperatures will fall pretty quickly tonight via radiational cooling. Clouds may increase a bit as we head closer to daybreak — particularly to the west of NYC — but that won’t be before temperatures generally fall to around 20 in most NYC suburbs, mid teens in snow-covered NW regions, and low-to mid 20s in NYC itself.
As we head to Saturday, the airmass will be modifying pretty quickly, as 850mb temperatures rise. This is because the high pressure will be moving to our east, giving us a return SW flow an an approaching warm front. However, the warm front will lead to an increase in clouds, which will prevent surface temperatures from rising much. Highs will be in the upper 30s, with the chance of some light snow showers and snow flurries — perhaps mixing with rain showers closer to the immediate coast. There is not a lot of lifting with the front, so precipitation will be spotty and not heavy — and any snow should not accumulate.
