“Five Things You Need to Know Today” is a Patch column that provides readers with essential, daily information at a glance.

1. More rain possible: There’s a chance of showers today, mainly after 8 a.m., and again this evening after 1 a.m., according to the National Weather Service. The rest of the day will be cloudy with a high near 57 degrees and a low around 49.

2. Groundbreaking: The big day is here! After many years of trying to bring a new senior center to Needham, supporters will break ground on the new building today, with a ceremony set to begin at 9 a.m. at the site at the corner of West Street and Hillside Avenue. The festivities will feature guest speakers, and refreshments will be served following the ceremony. Weather permitting, Needham seniors are encouraged to walk the half-mile from the current Senior Center location at 83 Pickering St. to the new location at 300 Hillside Ave. Walkers should meet at the Stephen Palmer Senior Center at 8 a.m. (Note: All regular services and programs will be cancelled from 8:30-10:30 a.m. because the Senior Center will close for the groundbreaking.)

3. Book launch: Olin College professor Caitrin Lynch will give a talk based on her new book, “Retirement on the Line,” at a book launch event set for 5:30 p.m. at Olin. This program is co-sponsored by North Hill. It is free and open to the public. RSVPs are requested by not required. To RSVP, call True North Courses & Events at 781-433-6400 or e-mail RSVP@NorthHill.org.

4. Crafts at the library: Children ages 2-6 can drop by the Needham Free Public Library today at 4 p.m. for Mother Goose Day craft activities. This program is free, and registration is not necessary.

5. Artists wanted: The Needham Merchants Association is looking for Needham artists to participate in a new public art project. Artists will decorate plain Adirondack chairs that will be displayed at businesses around town this summer and auctioned off in September to raise funds for town beautification projects and scholarships. The group is also looking for local businesses to sponsor a chair. For information, contact Nancy Wright at nancy.pdesigns@gmail.com or 781-449-7227
