Currently in the Twin Cities — September 29, 2023: Here comes summer again
Plus, a flash flood threat for NYC.

The weather, currently.
Here comes summer again
The drought monitor shows much improvement, no surprise. Most of the metro is in severe drought now versus extreme drought a week ago. Our rainfall deficit is still at 5.74 inches (since June 1).
Here comes summer again. After a dreary and cool week, temps soar to near 80 on Friday and we’ll be into the 80s Saturday through Monday, maybe even Tuesday. Those readings are nearly 15 to 20 degrees above normal. Look for possible spotty storms early Friday and again Friday night as warmer, more humid air blasts in. We’re in for a substantial cool down late next week with two possible rain systems.
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.
