Should I send another text?

So I downloaded hinge the dating app about two weeks ago and I matched with this guy. All of last week we talked that he asked for my number. We’ve been texting a lot that on Saturday he asked me if we could go meet up and go for a walk. I agreed and told him to let me know when. 

He told me what time he’s usually done work this week and asked which day of this week works best. 

I replied and I took a screenshot on the weather for this week said “ well I took a look on what the weather is going to be like since we’re going for a walk and all, we can go out either Monday, Tuesday or Wednesday since those are the days that is not going to rain” 

He hasn’t replied to my text since Saturday... should I follow up with another text? If so what do I say?
