I am not sure if you are the only one, LOL. But the color shading is a representation of the forecasted high temps for the day, the key is at the top of each map. The numbers are the exact high temps expected for that location.
The flags represent the general wind direction for the day, keep in mind that wind direction can change as the day goes on, especially when a front or low is moving through. The way to read the wind flags is that they extend in the direction they are coming from. So a flag pointed at 6 o'clock would represent winds from the south. A long tick on the end of the flag = 10 mph, a short one = 5. So 1 long, one short = 15 mph. Two long = 20 mph, etc.
