Voters casting ballots in the runoff elections from the May elections can start heading to the polls this week for early voting.
Monday was the first day of in-person early voting which ends Tuesday, June 14. Election Day is June 18.
Voters in some of the biggest cities in North Texas will select a mayor.
In Dallas, the city's former homeless czar Mike Rawlings earned 41 percent of the vote in May and faces former Dallas Police Chief David Kunkle, who had 32 percent.
The Dallas mayor's seat was vacated by Tom Leppert earlier this year. He then announced he would run for Sen. Kay Bailey Hutchison's seat in 2012. She is retiring.
In Fort Worth, former tax assessor Betsy Price earned 43 percent of the vote. She is in a runoff with former Councilman Jim Lane, who got 26 percent of the May votes.
Fort Worth had what many called the first competitive race in decades after Mayor Mike Moncrief decided not to seek re-election after eight years in office.
Irving voters will have to decide between Herbert Gears and Beth Van Duyne in the runoff. Van Duyne took 41 percent of the May votes to Gears' 38 percent.
There are also a handful of runoff elections for council members in several North Texas cities as well as school district trustees.
