Why are 'lows' and 'highs' in the plural? I would expect the low of 6 degrees and the high of 20 degrees.

Do 'lows' and 'highs' in the plural mean that the lowest and highest temperatures will appear more than one time?

Multiple instances of low temperatures of 6 degrees, and of high temperatures of 20 degrees are expected.

Can I also say these?

b. Multiple instances of a low temperature of 6 degrees, and of a high temperature of 20 degrees are expected.

c. Multiple instances of a low of 6 degrees, and a high of 20 degrees are expected.

I'm sure they measure in more than one place. So temperatures (in the region) will have lows as low as 6.

Can I also say these?

(A) Multiple instances of low temperatures of 6 degrees ....

(B) Multiple instances of lows of 6 degrees ....

(C) Multiple instances of a low temperature of 6 degrees ....

(D) Multiple instances of a low of 6 degrees ....

-------
1. Can I say (A) = (B), and (C) = (D)?

2. Do (A), (B), (C), and (D) mean the same?

3. Are they equally natural?

 

[Tarheel]

They all look good to me.

Talking about "multiple instances" in a weather forecast is completely unnatural. The original text is natural.
