Which is the best grammatical way to answer this question.

Would you like to have a picnic on Sunday?

Yes, I would. Because it will be sunny weather.

or

Yes, I would, because it will be sunny weather.

Is there any grammatical problem with starting a sentence with "because"?
Should a comma always follow "because"?

Thank you for you kind help!

It is possible to start a sentence with "Because" but not in the example you gave.

However, the main problem with your example is that you can't say "it will be weather".

It will be good weather, maybe?
It will be hot.
It will be sunny.

So, in answer to the original question "Yes I would [like to have a picnic on Sunday] because I think it will be hot.

Perhaps you'd like to reword your example sentence.

In Englsih every pronoun must have an antecedent. That is, a noun
that the pronoun replaces in the sentence.

In your sentence 'it' is a pronoun but we can't tell what noun
it is replacing.

Also, the expression 'because it will be weather' doesn't make any sense in Englsih.

If you meant for 'it' to refer to 'Sunday' then you could say"

"Yes I would because the weather will be fine on Sunday."

There would be no reason to put a period after 'would.'
because the sentence only consists of one complete thought.

I just noticed the adjective describing the weather was missing. Thank you.

In Englsih every pronoun must have an antecedent. /QUOTE]It seems to me that that statement is incorrect.

The following are acceptable and natural:

It's three o'clock.
It's raining.
It was windy yesterday.

[bwkcaj_ca]

Sometimes the antecedent is implied, not explicit, but it still exists.

No. We do not say, "The weather is raining".
