The Wx24 Pilot app will allow you to create a custom flight category based on your own personal minimums, with your own ceiling or visibility, wind speed, and weather conditions such as FZRA or +TS!  The app will check METARs and TAFs and render in black anytime your personal minimums are exceeded.

VFR or IFR categories do not show of the the full nature of the weather forecast.  Certainly dangerous conditions such as freezing rain, thunderstorms or a squall line can exist in VFR.   But what if you could instantly check to see if FZRA or winds greater than 30 kts are in the METAR or TAF?  And on every enroute TAF on your flight path!

Below is the personal minimum setting screen showing some of the settings and the corresponding visual TAF is shown to the right.  The black area exceeds the minimums set with an indication of what weather threshold has been exceeded.
