I know I’m probably jinxing it, but here goes: the weather is supposed to be gorgeous this weekend, and it looks like summer has arrived in Cambridge and Somerville. If the meteorologists (and me, I guess) are correct, sunny skies will greet two events happening tomorrow, and if you can make it to both, you should.

First, starting at 9am, the Union Square Farmers Market re-opens for the summer. Each Saturday, from 9am-1pm, farm-fresh produce from around our Commonwealth is on display at Union Square, along with delicious pastries and desserts from local bakeries. This year, two new farm-wineries join the rotation, and at tomorrow’s event, patrons will enjoy live music from The Splinters.

When you’ve had your fill of live music and delicious food in Union Square, head down to Riverfest on the banks of the Charles for…more live music and delicious food. I’ve written about this before, but Riverfest is the Cambridge Arts Council’s biggest event of the year, and hundreds of thousands of people are expected to attend. Bring your dancing shoes, bring your family, bring your friends, because with multiple stages and hundreds of artisans and food carts, this year’s Riverfest promises to be a good one.
