The domain name worth around $125 up to $150 if you are selling it on open markets. To gain a higher price, start searching for weather publications and related publishers. If you want to sell it for over $300 - $400, consider a longer timeframe (I estimate around 3 up to 5 months). I personally like to flip domain names on short term, is more lucrative if you want to roll some $ in the game. I hope it makes sense. Good luck!
