NEW YORK (CBSNewYork) — Wednesday will mark the last day of the month, and April showers – perhaps even April downpours – will come your way throughout the day.

The chilly temperatures that accompanied the gloomy, overcast skies on Tuesday will persist Wednesday, CBS 2’s Lonnie Quinn reported.

Heavier rain that was hovering over the southern end of New Jersey Tuesday evening will work its way north, and persist to make Wednesday the wettest day of the week.

The high for the day is expected to top out at 50 degrees on Wednesday.

Meanwhile, ahead of the heavy rain, a coastal flood advisory is in effect until midnight Tuesday night for the five boroughs of New York City, much of Long Island, and Hudson, eastern Essex, and eastern Union counties in New Jersey.

An unusually strong high-pressure system was moving offshore Tuesday night, and a warm front was moving northeast for an extended period of strong east winds. The winds will combine with high tide brought on by the new moon to produce widespread minor tidal flooding through the night.

The flooding will affect south shores facing the Atlantic Ocean, eastern New Jersey shores, the shore of Staten Island, the inland back bays of Long Island, and the coastlines of New York Harbor.

Beach erosion is also possible, the National Weather Service said.

The rain is expected to grow into severe storms on Thursday, with thunderclaps likely to ring out, Quinn reported. But in the afternoon, a southwest wind will make for a major change in temperatures, bringing the high up to 75 degrees and close to 80 in some areas.
