The weather, currently.
Warm sunny weekend, and maybe overnight showers
The weekend forecast is sunny and warm overall, with moderate winds continuing. Daytime highs Friday through Sunday will linger in the high 60s. Nighttime lows will be in the high 50s.
One unusual blip on the radar: on this full moon Friday, there’s a slight chance of overnight showers extending into Saturday morning. It may not amount to much, but every bit of precipitation matters in the Bay Area.

What you need to know, currently.
An extremely heavy rainstorm is forecast for Friday near New York City, with the potential for record-setting rainfall that could create widespread flash flooding.
Heavy rain — 4-6 inches — is expected over a wide swath of metro New Jersey, NYC, the Hudson Valley, and western Connecticut. In an extreme situation — if everything lines up perfectly — some locations in Brookyn, Queens, or Nassau county could get upwards of 6-12” of rain or more. In a worst case scenario, the state’s all-time 24-hour rainfall record could be in jeopardy. (13.57” at Islip on Long Island set on Aug 14, 2014).
[Key Messages]: Heavy rainfall likely with potential of scattered to numerous areas of flash flooding late tonight into Fri night. Flood Watch is in effect for much of the area during this time. Closely monitor the forecast & prepare to take action if warnings are issued.

Water temperatures in the Atlantic Ocean just off the East Coast have been at record levels all summer, the perfect fuel for excessive rain. And a slow-moving storm system is all it will take for this fuel to turn into a major flood threat.
