Stewart and Jeter, the only sub-11 seconds female sprinters already this year, have both turned in impressive performances.
The Olympic silver medallist Stewart has the two fastest times over the short dash this year, at 10.92 seconds and 10.93sec and she has set her sights on another quick time before the Jamaican championships.
Jeters in the meantime, has won all three of her races this season, including her victory over a strong field at the Reebok Grand Prix in New York last Saturday.
Her 2009 best effort of 10.96sec is the third quickest for this year.
The pair will be joined by Olympic champion Shelly-Ann Fraser of Jamaica, American 2005 World Championships gold medallist Lauryn Williams, and her American compatriots Muna Lee and Marshevet Hooker.
