NYC Weather Update – Aug 17, 2015

A heatwave over the weekend breaks Tuesday, as we enter an extended period of unsettled weather for the mid-week period. Temperatures cool off somewhat into the mid-80s, slightly above average for this time of year. Each day, except Tuesday perhaps will carry some small but non-zero chance of rain.

Rest of today – the possibility exists for some isolated thunderstorms to form over portions of the region this afternoon. The setup would be similar to yesterday when the temperature differential resulting from a sea breeze served as the trigger for some slow-moving storms. Plenty of instability from the heat and humidity and very little convective inhibition will mean that storms could form rapidly. However, the exact location of where these storms form is difficult to pinpoint. Areas that experience storms could expect heavy rain, otherwise expect mostly sunny skies with high temperatures that could touch record levels in the mid-90s.

Tuesday – a bit cooler with temperatures in the upper-80s and sunny skies to start, clouds increasing towards the evening.

Wednesday – high temperatures will cool off further into the mid-80s under cloud cover, and there will be a chance for rain throughout the day. This precipitation is associated with a slow-moving cold front approaching from the west.

Thursday – a similar day to Wednesday, perhaps with a bit more sun, but highs again in the mid-80s and a chance of rain through the day
