NYC Weekend Weather – Nov 20, 2020

We’ll see warmer than average temperatures around 60ºF to start the weekend before a cool off into the 50s Sunday. Temperatures rise again Monday into the upper-50s with a warm front approaching, then cold front bringing a chance of rain. Looking ahead at Thanksgiving temperatures seem like they should be mild we may see some rain in NYC.

Rest of today – sunny with highs generally in the upper-50s to near 60ºF. High pressure south of the region will lead to southwesterly flow that will bring us these mild temperatures. Overnight lows in the upper-50s.

Saturday – a cold front is forecast to move through during the day, however, this front should be deprived of any significant moisture. Temperatures should remain mild in the upper-50s to around 60ºF once again. It won’t be until the overnight hours when temperatures start to drop in response to the cold front passage, with winds turning towards the north and lows falling into the low-40s.

Weather Prediction Center surface forecast for 7AM Saturday, showing a cold front approaching from the northwest.

Sunday – mostly cloudy with high temperatures cooling off to around 50ºF. A warm front approaching from the southwest should stabilize temperatures and prevent much of a change overnight with lows barely budging in the upper-40s. The warm front, then a cold front following on its heels should bring us a round of showers.

Monday rain diminishing early on. High temperatures in the upper-50s occurring early in the day prior to the cold front passage. Temperatures dropping steadily during the day after this into the 40s. Overnight lows in the upper-30s.

Looking ahead at Thanksgiving, there could be some rain coming our way though temperatures appear like they should be on the mild side.

GFS model 500 mb vorticity and height forecast for 7AM Thursday. A closed upper low over the Ohio valley is evident with lots of accompanying vorticity. Should this scenario actualize, we would expect to see some showers in our area during the day Thursday.
