NYC Weather Update – Jun 11, 2019

After a rainy start to the week, high pressure takes over during the mid-week period. Another storm system moves in Thursday. Behind this next bout of rain, a dry and mostly sunny weekend should await us.

Rest of today – skies clearing as a cold front pushing. Winds picking up with some subsidence (sinking air, since air mass behind the cold front is cooler and drier). High temperatures reaching into the upper-70s with this subsidence and some downsloping from the northwest. Overnight lows in the mid-60s.

Wednesday – high pressure remains firmly rooted over the area. High temperatures in the mid-70s with mostly sunny skies. Overnight lows in the low-60s.

Thursday – a developing low closer to the coast and another one further inland over the Great Lakes will bring showers and thunderstorms to the area. First, like Monday, a warm front will lift through earlier in the day, then a cold front is expected to follow later on. High temperatures in the low-70s due to rain and cloud cover. Overnight lows in the upper-50s.
