Could you please tell me if I placed these commas correctly?

1) With all this rain, I, too, am beginning to miss the sunshine.
2) They predicted a nice weekend, though.
3) Luckily, it isn't cold.

Thank you.

They all look correctly placed to me, yes.

Thank you very much!

You're very welcome. =)

Sure! Let's go through each sentence and discuss the placement of commas.

1) With all this rain, I, too, am beginning to miss the sunshine.
In this sentence, the commas are placed correctly. The first comma is used to set off the introductory phrase "With all this rain." The second comma is used to set off the interrupting phrase "too." It indicates a slight pause in the sentence.

2) They predicted a nice weekend, though.
The comma in this sentence is placed correctly. It is used to set off the conjunction "though," which connects a dependent clause to the main clause. The comma makes the sentence easier to read and clarifies the relationship between the clauses.

3) Luckily, it isn't cold.
The comma in this sentence is also placed correctly. It is used to set off the introductory word "Luckily." By adding a comma, you are creating a slight pause before the main part of the sentence.

In all three sentences, the commas are used to improve clarity and readability. They help separate different parts of the sentence and indicate pauses or distinguish certain words or phrases.
