Narrative:
Multiple complex things were happening which led to me potentially violating an minimum IFR altitude (mia) (I'm unsure as I couldn't tell if the was the warning stick of the actual MSAW alert). During the lead up to the event there were multiple aircraft deviating for weather; a flight of fighter jets had [requested priority handling]; and a C206 was having difficulty avoiding weather (as well as the pilot sounded spooked and afraid on frequency). Aircraft X flight was returning to base from the military airspace and requested vectors for the TACAN14. I vectored them northwest outside of mupee descended them to 090 and gave them a turn to intercept the LMT314 radial. During this time there was multiple pilot requests from other aircraft; nexrad weather to call; and several other things going on at the same time. During the turn on; I believe the aircraft may have drifted; or may have gotten close to the 100 mia just to the west of the LMT314 radial.during fighter missions to decrease sector pressure; kingsley approach could open up. Also; while the approach quick cards on sector 10 are nice; trying to flip through the booklet and figure out which approach is which (they all look the same) was hard and became a distraction. Maybe make the title of each approach reference card larger. Also the MSAW warning vs alert looks the same (save for the warning stick.) in this case; with tight quarters; nexrad weather overlaid; and multiple data-blocks; it was hard to decipher what exactly was happening.
