NYC Weather Update – Dec 10, 2018

This week features a continuation of the same general pattern we’ve experienced over the past week with below normal temperatures and no precipitation to speak of. Temperatures will remain cold through the majority of the work week until a pattern change this weekend brings a return of more seasonable (and even above average) temperatures along with the potential for a coastal storm that is expected to bring be all rain.

Rest of today – sunny and cold with high temperatures topping out around 40°F.Overnight lows quite chilly in the upper-20s to 30°F in the city. Clear skies and calm winds expected, giving rise to excellent conditions for radiational cooling.

Tuesday – very similar profile to today, another mostly sunny to sunny day with high temperatures in the upper-30s. More clouds expected overnight should help offset some radiational cooling, but still cold with lows around 30°F again.

Wednesday – broken record type of forecast here, yet another day of temperatures in the upper-30s. There’s more potential for cloud cover with this day due to the influence of a cold front which is forecast to move through. At this time, it doesn’t look like there’s enough moisture in the atmosphere for this to trigger snow showers. Cold again overnight with a reinforcing shot of Canadian air associated with a high pressure center behind this cold front. Lows in the mid-20s overnight.
