Narrative:

Flight received numerous reroutes to den due to significant thunderstorm activity in ok. After receiving a third reroute for WX avoidance; the crew relayed that they estimated landing den with 5600 pounds of fuel; which would be 200 pounds less than the required far 45 min reserve of 3800 pounds and the burn of 2000 pounds to the required alternate of cos. After reviewing the en route conditions along with the WX and ATC considerations into den and cos; the captain and dispatcher agreed there was no other safer course than to continue to den with the possibility of landing under 5800 pounds in den. In addition; the flight received more direct course into den; and relayed an estimated landing fuel of 6200 pounds into den; above the required minimum. Upon landing in den; flight monitoring record showed a block-in fuel at den of 5300 pounds. Callback conversation with reporter revealed the following information: reporter stated that he had been monitoring fuel for flts operating in the area affected by thunderstorm activity. With no arrival delay anticipated for den airport; the joint decision was made to continue to destination. Destination airport required an alternate for low ceilings. Visibility was good with no thunderstorm activity forecast for den.
