What have you been wearing over the last 2 months kf riding when itit was in the 50s and 60s?
Bring that stuff if you are worried about the temp dropping 20deg under what it was this morning.

...a pair of lightweight tights balls up to a softball and weighs basically nothing in my mind. Have a lightweight rain jacket from Novara or PI and that will more than warm your torso and arms. $50 for the Novara one and you can remove the sleeves too.

These sort of jackets warm you up like crazy.

https://www.amazon.com/Pearl-iZUMi-I.../dp/B0089DP1M2 this is prob not needed, but if you are concerned about riding in 50deg weather, it doesnt hurt to bring along when there is a lot of wind with that 50deg temp. Keeps your ears warm but doesnt overheat your head. Most important, it keeps earache away due to wind and cold. Prob not needed in even 50s weather, but this seems like a legit post and not some trolling thread, so here are legitimatw suggestions.

I have a Saucony Drylete headband which is thinner than the PI, so i dont have experience with the PI.

I do have a Novara conversion jacket and love it for what i use it for- spring/fall morning rides where it starts out very cold and is expected to warm up.
