Firstly, it's not a palm, it's a cycad (Cycas revoluta), a.k.a, "Sago Palm". They are native to a humid, subtropical climate where the highest temperature they would ever encounter would be around 95 F.. In a humid, rainy climate they can take full subtropical sun (once acclimated), in your climate, this species is probably not the best species and there are other cycads better adapted for a a hot, arid climate (although your species is the one most commonly sold all over the USA). I am in a very humid, rainy summer climate and all my "Sago Palms" in either full or partial shade and all flushed vigorous new growth this year, without any yellowing even in my own climate will burn some in hot, direct sun.). The pot is big enough. I would aim to keep the soil on the dryer side until there is new growth. I also would not feed at this point. Good luck.

Need a closeup of undersides of leaves and trunk.
