After months of campaign ads and candidates' speeches, Floridians will head to the polls Tuesday to decide who will make it onto November's ballot.

Polls will be open in the Central Florida and Tampa Bay areas from 7 a.m.-7 p.m. Tuesday. (Statewide, some Panhandle counties on Central Time won't close till 8 p.m. ET.)

Tuesday's election is a primary, which means candidates and races at the federal and state level — such as U.S. House and Senate and Florida Legislature — as well as statewide amendments and municipal elections, will be on the ballot. Remember that Florida is a closed primary state, though any voter can cast a ballot for nonpartisan races and constitutional amendments.

Stormy weather threatens to make things interesting this week. Tropical systems to our east and south are very likely to keep showers and thunderstorms in our forecast, prompting Florida's Secretary of State Ken Detzner to issue a statement ahead of Election Day:

“Although it is too premature to determine if voters will be impacted by adverse weather conditions, I am in constant contact with Governor Scott, the Division of Emergency Management, and Supervisors of Elections. Any updates that have the potential to impact Florida voters will be immediately communicated. In the meantime, visit YourVoteFlorida.com or contact your local Supervisor of Elections office for more information."

As for the primary's races, the marquee matchup is the statewide U.S. Senate race. Sen. Marco Rubio is campaigning as though he's all but won the Republican contest over main rival Carlos Beruff, a developer who has spent about $8 million of his own money for his first run for office.

On Monday, Beruff appeared to shut down the campaign. Rubio re-entered the Senate race after losing the Florida presidential primary in March to GOP presidential nominee Donald Trump.

On the Democratic side, U.S. Rep. Patrick Murphy and Rep. Alan Grayson are battling to take over Rubio's seat. Murphy has picked up major endorsements, including President Barack Obama's.

"Because I care about rolling up my sleeves and getting to work," said Murphy, a Democrat who lives near Jupiter. "Maybe I'm a glutton for punishment. But I enjoy flying to DC, being the voice for my constituents on the Treasure Coast. And I want to do the same thing for Florida."

Grayson, meanwhile, has a reputation for being outspoken. The self-proclaimed "congressman with guts" may be best known for saying the Republican health plan has three parts: Don't get sick, but, "If you get sick, America, the Republican health care plan is this... die quickly."  

Grayson has the support of progressives, as opposed to the establishment. He has also faced accusations of ethics violations, which he denies.

Grayson visited his phone bank volunteers Monday, but was not available to speak. He will be watching the returns from Kissimmee on Tuesday.

Recent polls show both Grayson and Murphy would lose to Rubio if a general election was held today.

This is the first Florida election since the Congressional district maps were redrawn last year, after the state Supreme Court ruled that lawmakers violated a constitutional amendment mandating that districts be drawn in a way that doesn't favor incumbents or parties.

As a result, there are three U.S. House and 22 state Senate incumbents who aren't running in the same district as their current one.

The entire state Senate is up for re-election this year, but 12 candidates have no opposition.

Voters will also see a constitutional amendment on Tuesday's ballot. Amendment 4 would provide property tax breaks for homes and businesses that install solar panels. Both environmentalists and business interests support the measure, which as a constitutional amendment must receive 60 percent approval to pass.

According to the latest numbers by the Florida Division of Elections, almost 536,000 people voted during the early-voting period that ended this past weekend. Another 1.15 million voted by mail, making about 1.7 million Floridians who have already cast their ballots for this year's primary. For the 2012 primary, 2.34 million total voters cast ballots.

Florida has almost 12.4 million registered voters.
