Yes, that's right, smog and an impending cold front across Britain could stop you seeing the moon passing directly between the sun and planet Earth.
So while, this year's solar eclipse is tipped to be the best we have ever seen, as between 85% and 95% of the sun is set to be obscured, cloudy weather could stop us from seeing it happen.
If you are lucky enough to be in the Northern and Western Isles of Scotland, meteorologists say you'll be able to experience a stronger solar eclipse with a near 98% of the sun obscured at its peak.
The next time we'll be able to witness another major solar eclipse is in 2026.
But don't give up hope just yet. BBC Weather meteorologists say the clouds could clear up, just in time for the solar eclipse.
If you've just woken up to cloudy skies don't give up totally on #Eclipse2015 Cloud is fickle & could clear in the next hour or 2. Alex D
