I guess a flood watch could still be issued by upton

A cold front will slowly approach and move through the area Thursday into Thursday night. A period of moderate to heavy rain with embedded thunderstorms will move through Thursday afternoon into Thursday evening. There is the potential for isolated to scattered instances of flash flooding, with rain rates of 1 to 2 inches per our possible during this time frame.

A slow-moving cold front will likely bring showers or thundershowers to the region tomorrow into tomorrow night. Parts of the region could experience flooding.

The frontal passage will be followed by a reinforcing shot of cooler air. Friday could see highs in the lower 80s with some additional showers or thundershowers. The weekend could feature cool and perhaps unsettled weather. The greatest chance for rain will be on Saturday.

Somewhat cooler than normal weather will then extend into at least the middle of next week.

The ENSO Region 1+2 anomaly was +4.0°C and the Region 3.4 anomaly was +2.7°C for the week centered around August 12. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.80°C and the ENSO Region 3.4 anomaly has averaged +2.32°C. The ongoing strong El Niño, which has reached super El Niño threshold, will continue to strengthen through the summer.

The SOI was -28.34 today. 

The preliminary Arctic Oscillation (AO) was +0.178 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 53% probability that New York City will have a warmer than normal August (1991-2020 normal). August will likely finish with a mean temperature near 76.2° (0.1° above normal). 

Supplemental Information: The projected mean would be 1.0° above the 1981-2010 normal monthly value.
