Not only has Iran closed its airspace tonight (Wednesday) and tomorrow night (Thursday) for "training exercises including live fire", it has also announced the following:" All Iranian government offices and banks in Tehran province and the neighboring Alborz province will be closed on Wednesday", citing a 'significant rise in temperature' as the reason.
What is even more suspicious is that Varamin, Iran's 3rd biggest town, situated just 30 km away from Tehran, will be experiencing a much higher temperature (44C / 112F), yet nothing will be closed there.
Additionally, America is now seeing increasing signs of Iranian preparation, which it has not seen until now.
