题目分析：
本题难度较大，需要看清每个成分。
选项分析：
A选项：连词as身后是由并列连词and连接起来的合句，即， a broad area of high pressure will build和a broad area of high pressure will bring fair and dry weather for several days. 在逻辑上，能带来几天干燥的天气的应该是前文的两个天气现象，不应是a broad area of high pressure。
B选项：选项末尾的that bring fair and dry weather for several days是定语从句，其修饰对象为a broad area of high pressure，这造成的错误同选项(A)。
C选项：本选项具有语法错误，最后的并列连词and身前building不能做谓语动词，这造成了语法错误。
D选项：with a broad area of high pressure building是独立主格结构，其无法和身后的动宾短语bring fair and dry weather for several days形成并列关系。如果将并列连词and身后的动作理解为和主句will continue并列，则需在该独立主格身后也加上逗号，让独立主格变为插入语。
E选项：Correct. 本选项在语法和逻辑上均是正确的。值得注意的是，划线部分最后的非限定性定语从句which will bring fair and dry weather for several days在修饰其身前的两个事件的共同结果。正常来说，定语从句只能修饰一个名词，不能修饰句子，这个原则是没有问题的。但为什么本题又可以修饰句子了呢？答案很简单，这不是GMAT考试双重标准，而是这些语法内容并非考试的真正考点。有些考题，利用定语从句修饰名词，同位语可以修饰句子的原则来考查我们考生判断逻辑主语的能力，这个时候，定语从句自然只能修饰名词，不能修饰句子。例如：https://gmat.la/question/Prep2008E1-SC-206
但有些考题，比如本题，对于出题人来说，由于他的考纲里根本没有对这些语法细节的要求，所以他想当然的就会按照英语的使用习惯而把句子写成了which修饰身前整句。因此，对于这点，大家不必记为一个考点，只需要记住，看题目怎么考我，如果有选项是同位语和定语从句交替出现的，肯定要保证定语从句修饰一个名词。如果类似于本题，没有同位语的选项，那么which引导的非限定性定语从句，也可以修饰整个句子。
This uses a quite idiosyncratic idiom, involving the verb "to usher." The literal use of this word is the action of the person called an "usher," the person in a theater or at a classical concern who escorts patrons to their seats. Metaphorically, it is used about anything that brings something into existence. The basic idiom is:
I usher X in.
If I want to specify the region in which this X is introduced, I would say:
I usher X into A.
The "in . . . into" is redundant and wrong: choice (A) & (B) have this, and the "in . . . to" in (C) is far from ideal. Choices (D) & (E) get the idiom completely correct.
This is not a strict rule, but "continue" +[infinitive] sounds formal and sophisticated, whereas "continue" +[gerund] sounds casual and colloquial.

Choice (E) is the tricky one. A comma-which modifier refers to a noun and that noun has to be close enough to the modifier that the relationship is clear. In this case, a broad area (of high pressure) is that noun, and it is in fact only one word away from the modifier—but, unusually, a verb (builds) comes in between. A lot of people will cross this answer off because, typically, a verb does not intervene between a noun and a noun modifier.
This particular clause (while a broad area of high pressure builds) is itself a modifier of the main sentence that appears before it. In this case, the author must choose between these two constructions:
… while a broad area of high pressure builds, which will bring fair and dry weather for several days.
… while a broad area of high pressure, which will bring fair and dry weather for several days, builds.
Given the length of the noun modifier—and the shortness of the verb—an author might choose to place that verb first. Think of this as an extension of the convention that a noun followed by two noun modifiers will place the essential modifier first:
The box of nails, which is sitting on the table, …
It’s still clear that the second modifier refers to box, as in choice (E) it’s clear that the which modifier refers to the broad area of high pressure.
