Showers returned Monday evening, the National Weather Service says, along with a possible thunderstorm overnight.

Monday night will see a low of about 47, forecasters said, as winds shift to the northwest, and there is a chance that the overnight rain and storms could linger into Tuesday morning. By afternoon it should be a sunny, albeit chilly day with a high of 57 degrees.

Wednesday through Monday of next week, the weather service said sunshine will be the order of the day, along with clear nights.

Expect daytime temperatures in the mid-to-upper 50s the remainder of the week, with temperatures dropping into the low 40s overnight.

A small craft advisory will be in effect from 8 a.m. Monday through 2 a.m. Tuesday for all Atlantic Ocean waters from Sandy Hook, N.J., to Montauk Point and offshore to 20 nautical miles, the weather service said. The advisory warns: "Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions."

The advisory also is in effect from Montauk to Martha's Vineyard from 11 a.m. Monday through 8 p.m. Tuesday — and for Block Island Sound until 7 p.m. Monday.

The weather service has announced its New York metro area office has extended the Frost/Freeze Program, designed to alert gardeners and growers of actions that may be needed to protect any tender vegetation from harmful cold temperatures from Nov. 1 to Nov. 11 in Suffolk and northern Nassau and from Nov. 11 to Nov. 21 in southern Nassau and New York City. The alert program began in both areas April 1.

During the program window the weather service issues frost advisories and freeze warnings. The program dates are being extended as part of an experiment, corresponding to the estimated 75th-to-90th percentile probability of the first freeze date.

Frost can occur when temperatures fall into the mid-30 degree range, the weather service said, with frost becoming more widespread below 32 degrees — when a freeze is possible. A so-called hard freeze is possible when median temperatures fall below 28 degrees.
