Send Email When Attribute/# Enters Range. Don't Send Email When New Attribute Updates Are In Same Range

Question

I am working with Heat Index values and I want to be able to only send emails when a heat index value, for example enters into the range of 88 to 93, but I don't want to send an email if the subsequent attribute value updates are within the same range as the previous value.  Anybody have any helpful ideas on what tools or combination of Arcade to make something like this function?

I would combine either an Incident Detection node with a Filter By Express (Start, Stop, Ongoing) and Control Event Volume node, or simply a Filter By expression (Between x and y) with a Control Event Volume.  Probably the Incident Detection would work best based on your description.
