I have three folders of weather apps as well as three apps on the home screen!
I think I have settled on Fahrenheit as my favorite forecasting app. It has a badge for the current temp. Very simple to add other cities and page through them. Easy to scroll down for the two week forecast. Expands for more info if you wish.
I also like Umbrella to automatically tell me if I need to take an umbrella or not at 5AM. It very, very rarely does not tell me to, when I need to, and infrequently tells me to take one when I do not. I live in FL- it rains a lot.
For radar, as an overview, and being able to zoom in and out to see the whole region, I like RadarUS. Those are the three apps on my home screen.
If I want the latest, most up-to-date radar info, then Radar Pro is the one I turn to. If I want to know if I am in danger from severe weather- it's Radar Pro.
Lightning Finder is pretty cool- but you have to pay a yearly subscription. Still- I miss it enough when my subscription expires that I do so.
Sat Weather is pretty.
Hurricane is a must-have here.
I sort of like US Radar for traveling.
