True to form, the hottest temperatures of the year so far will be felt across many locations today as high pressure ridging continues to build across the southwestern US. Expect today to be much like yesterday, with the exception that the atmosphere has dried out a bit more (see &ldquo;<span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;precipitable water&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;The total atmospheric water vapor contained in a vertical column of the atmosphere.
