I wonder what the arrow is for? Also, the scripts required that the arrow be put in a different folder than the other "forecast icons" - wierd.
Anyone have any info on it?
The up arrow next to a low temperature just means that the temperatures will be rising through the night. You will occasionally see a down arrow next to a high temperature as well, which would indicate a daytime high achieved in the morning and temperatures falling through the afternoon.
You can expect to see these in our area a few times a year.
