A rundown on the state of the Boston mayor's race, as another heat wave hits the city:

-- Incoming! Suffolk University, working with the Boston Herald, will be releasing a poll of likely voters on the mayor’s race tonight. The numbers go up on the Herald’s website at 9 pm and on Suffolk University’s website at 10 pm.

-- State Rep. Marty Walsh’s campaign boasts that they knocked on over 22,000 doors this past weekend, the third weekend out of four that they’ve hit five figures.

We're STILL entering data, so the number will go up, but thanks to the volunteers who knocked 22,236 doors this weekend! #Bospoli #BosMayor

-- City Councillor At-Large Felix Arroyo isn't the only mayoral candidate going up with ads this week. Suffolk District Attorney Daniel Conley is going up on TV as well. The five ads, which are going up on cable and broadcast, focus on a range of topics, from education to gun violence. The ads are: "First," "Innovation," "No Place," "Together," and "Graduate." "Dan has been talking about these issues on the stump for months, so we're glad we can share his ideas with an even broader audience," campaign spokesman Michael Sherry said in a statement. "We wanted to focus on issues right off the bat- from Dan's ideas about reforming education to his work as District Attorney in getting guns off our streets. This is just the start of a conversation that we want to continue over the coming months."

-- Former state Rep. Charlotte Golar Richie, a former senior vice president at an organization focused on at-risk youth, is planning to hold a "youth summit" in the wake of the Trayvon Martin verdict in Florida. "As I spoke with young people, especially young men of color, after the Trayvon Martin verdict at Jeep Jones Park in Roxbury, and at the rally in Dudley Square, many said they felt the verdict signaled that their lives had less value than others,” Richie said in a statement. "Some young people said that too often society views them as the problem, not the solution. This meeting is about problem solving – and engaging our young people to help find solutions." The summit is set for July 27, with the location to be determined.

-- In the summer edition of CommonWealth magazine, Paul McMorrow looks at Gov. Deval Patrick's legacy: The people working on the mayoral campaigns in Boston. "The campaigns that win today are the ones that place their emphasis on building their ground games and cultivating organizers like [Dorchester's Joyce] Linehan, not on mailers or media buys or endorsements," McMorrow writes. "It’s not a question of recreating Menino’s operation; it’s about taking the grassroots organizing playbook that Michael Dukakis handed to Deval Patrick and Elizabeth Warren, and running with it harder than the rest of the names on the ballot."

-- City Councillor Rob Consalvo's campaign put up a map to track his movements across the city.

-- City Councillor Michael Ross, the chair of the City Council's Public Safety Committee, is holding a hearing on Wed., July 17, on the uptick in gun violence. The hearing is set for 5 p.m. at Hibernian Hall, with testimony expected from the NAACP and the Ten Point Coalition.
