Weather timeline: 2nd storm on the way

Wednesday morning

Expect clouds and fog during the morning commute. Temperatures will reach a high of 54 degrees. Wind speeds will remain weak, around 5 miles per hour.

Wednesday afternoon

The powerful storm system from the south arrives around noon, and the intensity picks up by 3 p.m.

Wednesday night

This is when rainfall rates peak at about 1 inch per hour, between 6 p.m. and 3 a.m. Thursday. Temperatures will dip to 44.

Thursday morning

The majority of the storm pushes north, with some scattered drizzle in NYC. The high temperatures will remain the same, around 52, but expect breezy conditions as the storm system moves away.

Thursday afternoon

Another round of rain returns around 1 p.m., but will fortunately be much weaker than Wednesday's system.

Friday

NYC gets a break, with sunny skies and a high of 55!

Weekend

Rain returns for the weekend, with the potential for another 1 to 2 inches. Additional flooding is possible.

Windy conditions are expected Sunday when that system exits the area.

Rainfall totals

New York City and northern New Jersey saw about ½ an inch of rain Tuesday, with lower totals on Long Island and Connecticut.

The city could see a little over 2 inches by Thursday evening, while parts of Long Island and Connecticut could see nearly 2 ½ inches. Areas further east aren't threatened by as much rainfall.

Significant flooding threats are possible throughout the entire area, according to the National Weather Service. Monitor river threats here.

"Soil moisture is running 60-80% above normal, with a majority of area rivers and streamflows running above to much above normal," according to the NWS. "This will allow for rainfall to more quickly become runoff and flooding. Each successive rain event will further elevate soil moisture and stream flows, increasing the urban and river flood threat."
