Still decent weather today, but more clouds and humidity later

It’s a pleasant start to the day throughout the Garden State — both on land and in the water, as depicted in this photo from about 9:15 a.m. near the Barnegat Inlet.

Mostly sunny this morning, with increasing cloud cover during the afternoon. The high pressure system that delivered fantastic weather the past two days has departed, and a southerly flow is here, kicking up the humidity throughout the day. Showers may form later, but they will be scattered and not widespread in nature. Temperatures will be similar to the past few days (upper 70s to 80 and low to mid 70s in the mountains). South wind around 10 mph. Clouds and the possibility of showers tonight, with lows in the 60s and upper 50s in the mountains.

For Wednesday, mostly cloudy with a threat of showers or a thunderstorm. High temperatures similar to today.

But for Wednesday night through Friday night, “several periods” of heavier rain and thunderstorms are likely, with the potential for “small areas of significant urban and small stream flash flooding,” according to the National Weather Service.”

In New Jersey, the primary threat area is the northern portion of the state, the service advises.

BOAT/BEACH: Clouds building this afternoon. Temperatures in the upper 70s, south wind at 5 to 10 mph, and small breakers and ocean swells. The surf temperature is in the low 70s, and there is a low risk of rip currents, but always swim near a lifeguard. Low tide in the ocean is during the early afternoon.
