New York Today: Prepare to Sweat

Bryan Thomas for The New York Times With the heat beating down, people on Sunday looked for anything to shield themselves. Look for more of the same through Tuesday.

The National Weather Service just let us know that it is going to be an oppressive start to the week, issuing a heat advisory at 4:02 a.m. on Monday. Hot, muggy and gross are in the forecast, with temperatures in the low 90s, an the heat index in the mid 90s.

Bring an umbrella. There may be a thundershower this afternoon, though the heat won’t start to break until late in the week. Yes, after so many cool days - suddenly, it’s summer.

Here’s what else you need to know first thing Monday:

TRANSIT & TRAFFIC â€" At least you won’t be sweltering in traffic jams or stalled subways, not yet anyway. No major tie-ups out there.

COMING UP TODAY â€"

- The City Council will vote on whether to send a package of stop-and-frisk reforms to the full council for a vote - the most significant action yet amid the ongoing war of words between the council majority and the mayor and police commissioner.

- If the Supreme Court rules on the federal or California same-sex marriage bans, there will be a rally or protest (depending on the outcome) outside the Stonewall Inn in the Village at 5:30.

- Open! ing arguments in the federal death penalty retrial of Ronell Wilson, who killed two detectives in Staten Island in 2003 (and fathered a son recently by one of his prison guards). His first death penalty sentence was overturned by a judge who said prosecutors prejudiced the jury.

- On the campaign trail, Anthony Weiner, Christine C. Quinn and John Catsimatidis will take questions at the CUNY journalism school’s Center for Community and Ethnic Media, while William C. Thompson Jr. will unveil a plan to provide financial aid for undocumented students.

- New Jersey flags will fly at half mast in honor of James Gandolfini.

- Don Rickles is not only still alive, he’s getting a “Lifetime Achievement Award” at the Friars Club tonight.

AND LASTLY â€" Cacao pods are ripening at the New York Botanical Garden.
