More than 40 people were shot in Chicago over the holiday weekend, and at least 10 of them were killed, NBCChicago.com reported.

The latest shooting happened around 1:30 a.m. in Albany Park, a Chicago neighborhood, where police said a man was shot in the face. It followed dozens of shootings across the city since Friday.

"It's been a real rough weekend, a lot of gun violence," community activist Pastor Corey Brooks told ABC News.

Most of the victims were in stable or good condition, but as of Monday morning several remained in serious or critical condition, including the Albany Park victim.

According to the Chicago Tribune, homicides have increased 49 percent so far this year, with 200 people killed in 2012 compared with 134 during the same period in 2011. Shootings are also up nearly 14 percent over last year, the paper reported.

Some experts believe warmer weather could be causing violent crime to spike.

"For us, when the weather's warm, the first thing we think, we're going to get some gunshots in here because we know people are out in the street," Dr. Larry Mitchell of Chicago's Roseland Community Hospital told NPR. 

The 66-degree average temperature in May is the warmest of any Chicago May over the past 35 years, the Chicago Weather Center reported. And Monday's 95-degree high is Chicago's warmest Memorial Day temperature since they started keeping records 142 years ago, according to the weather center.

But police superintendent Gary McCarthy is not ready to blame the weather for the city's spike in the murder rate.

"I'm not willing to chalk it up to the weather, the tides, the moons, voodoo, you name it," he told NPR. Instead, he blames Chicago's gang culture.

The weekend's most violent period was an hour-and-a-half stretch early Sunday morning, when 13 people were shot. The youngest victim is a 7-year-old girl shot Saturday afternoon in the arm as she was playing outside her home. She is expected to recover.

At least four teenagers were also killed in separate shootings this weekend.

Chicago Mayor Rahm Emanuel and police officials are expected to address the public Tuesday on new strategies aimed at reducing crime, ABC News reported. According to the mayor's office, they will announce "coordinated gang-reduction and neighborhood safety strategies."

Lord have mercy, what in the world is going on in Chicago?  SMH, they have had a rough few years of violence in that city and it only seems to be getting worse. And who are these so-called 'experts' that believe the warm weather may have sparked the increased violence in the city? They're acting like they had some kind of epiphany or something.  People have been saying for years that warm weather brings out the worst in people, however this killing spree in Chicago started waaaaay before the warm weather hit. A 49% increase from the numbers this time last year?  It's not even June yet!  Something really needs to be done about this.  I don't know if the National Guard needs to be brought in, or more police on the street, or what. But the community definitely needs to come together and brainstorm on what can be done to take their city back.
