Here in Oregon, that would be around 250 alerts/year. Seriously, if I were you, I'd put a lightweight rain jacket (maybe a Showers Pass or the like) in a sock and toestrap it to my seatbag for the months where in might rain. Then you can just do your routine and you are covered if it does rain.

I'm a step behind you technology-wise. I have yet to have a smart phone or apps. I do make breakfast and boot the desktop but often don't make a note of the weather beyond looking outside and at the thermometer. (I am riding in bike clothes and keeping work clothes at work, so arriving wet doesn't matter.)
