The Purgatoire River is particularly high after a pronounced river crest formed late Sunday. This morning&rsquo;s analysis suggests the river peaked earlier today in the &ldquo;Action&rdquo; level, and it is expected to stay below Minor flood stage.<\/p>\n<p>Looking out further, a strong surface high pressure system is set to move into Colorado starting Wednesday afternoon. It will usher in a fall-like cool front that will briefly interrupt summer.
