Weather Intelligence

How accurate is the weather intelligence accuracy for temperature, precipitation, and wind especially during thunderstorms?

I would say it probably is as accurate at the data received from the weather station (e.g. sensor(s) placed in not a good place) and how it compares to what you experience (how localized the weather patterns are). Even though the weather stations are pretty close by (a few miles away), I have rarely seen ice in the morning when it probably should have done a freeze skip.

I live the the Phoenix area and have very localized monsoon thunderstorms from July-September. The weather data accuracy is probably very important for flex daily.

You are correct, the accuracy is very important for flex daily. I would probably check to see how close the stations are to you and if it is within the very localized area.
