Toooo hot = Rain today

"It's going to rain today," the watchman tells me one morning. Looking up at the clear sky I'm a little skeptical but I say, "Oh, yeah?" "Yes. Today is toooo hot. It will rain." I've lived in East Africa almost five years now and this is, indeed, an indicator of rain but not one I've managed to navigate. There is some difference that I can't discern between mornings that are "hot" and those that are "toooo hot." "Toooo hot" means it's going to rain. To me, it just feels hot or not hot. The watchman was right, of course. Showers started that day in the early evening. Maybe he has a weather app on his phone and he's just playin' with me.
