than 前后是两个句子,如果用it yesterday那麽这个句子就缺少成分,原句中的it was yesterday省略了 worse 这个词,但原句这样是对的,而如果用the weather yesterday则显得累赘重复,一般比较好的是尽量不重复前句提到的主语,这样显得句子更上档次一些.
应该是一种省略现象
than表示前后句子的比较，既然是比较，自然要保持一致，前面是句子，后面也必须是，如果只是it，就不是个句子了，此外was后面省略了天气的具体状况，正确的断句是it was/yesterday。

相当于原句：the weather today is worse than the weather was yesterday.意思是：今天的天气比昨天的更糟糕。it 代指 the weather 为避免重复累赘。
