Is it weird to reach out to old PI after 3 yrs?

Hi all! I’m currently a 3rd year phd student and randomly today I realized I haven’t reached out to my old undergrad PI since my first month of phd. I worked for him for 1.5yr during undergrad and he helped me a lot during my application process. I originally planned to send him a email every year or so and feel super bad I just completely forgot about it (a bit of excuse for myself I didn’t handle phd during covid too well). I do wanna reach out just to reconnect and genuinely wonder how’s he doing. But at this time after 3yrs of no contact I’m also super awkward and don’t know what to say. Don’t know if I’m thinking too much into this. 

Would it be weird to reach out? Not great at stuff like this so would appreciate any input!

I don't see why it would be weird; it's always nice to stay in touch with people you had a good relationship with. Ask them how they are, how they handled the pandemic, what they're working on right now; tell them about the cool stuff you're doing in your PhD. Just do it, don't overthink it.
