On mine, there's also a line you can't see here which is horizontal at 32°F -- then I can see visually when the temp is going to drop below freezing.
I may have to think about adding that - good suggestion.
Maybe I could combine the data passing under that line with the chance of precipitation being above the line to put a huge red banner that says "City will freak out. Schools will close. Nothing will come of it." (My fellow south Louisiana forum members will totally understand that).
On a serious question, your temp axis is a sliding / auto-generated scale for the low end? I was debating doing that versus what I have now with the absolute scale, but could not decide what I liked best.
