Clear Skies

Clear Skies is a Dragon shout in The Elder Scrolls V: Skyrim.

Description
Clear Skies is a Dragon Shout obtained from the Greybeards after having finished the quest "Alduin's Wall." Using this Shout removes all weather effects (rain, snow etc.), and is needed to remove the wind barrier between High Hrothgar and the path to the Throat of the World. Oddly, Clear Skies does not appear to work in the close vicinity of Winterhold, unless it's used inside the College's walls. It does work in many other exterior areas of Skyrim, sometimes to fairly spectacular effect, and if you clear the skies near a group of persons without harming them, you may later be approached by a courier with an anonymous letter complimenting you on your abilities.

Bugs

 * If only one word has been read, and the main storyline has been completed before the other two have been read, the player will be stuck with one word of the shout and cannot read the other two. [Xbox 360 (needs confirmation)/PS3(confirmed)]
 * It can take multiple uses for this Shout to be able to clear Winterhold. It appears to work best when used while inside the grounds of the College of Winterhold, possibly due to it being on a higher elevation.
 * It is possible that even after the player uses the Clear Skies shout, the path to Paarthurnax still does not open. Unfortunately a solution has still not yet been discovered.
 * It is possible that if the player fast travels away without reading any of the words, it is impossible to read them again in the future. (needs ps3 conformation)/xbox360(confirmed)
