Severe WX alerts while in DND

[iFortWorth]

I know that most all weather apps will provide severe weather alerts. But what, if any will still alert at night during Do Not Disturb mode, much like alarm clock apps? Severe weather season is right around the corner for lots of us and would like to get this figured out. We had some bad storms come through a week or so ago and I awoken to several notifications of severe weather alerts from when I had been sleeping. None had bypassed the DND mode.

Thanks
