A few nuisance showers and weak thunderstorms popped up over the favored parts of the western Palmer Ridge and Front Range, scooting southeastward before dissipating. Up to 0.5 inches of rainfall occurred with the strongest of these storms, though this was by far the exception with most places recording a few tenths at best.<\/p>\n<p>The only major exception to the calmer weather was in far eastern parts of the state where a few thunderstorms briefly turned severe in Baca and Yuma counties. The former storm was warned for large hail and gusty winds, but not much rainfall. The latter storm produced up to 1.5 inches of rainfall in about an hour over a localized area right along the New Mexico border. Fortunately, no flooding or severe weather reports were officially tallied with these storms, although they occurred over very rural areas with few observers and gages.<\/p>\n<p>Finally, with the break in the active weather, we take a look at the extremely active period that occurred over the Arkansas River basin over the past 30-45 days. Below is the Arkansas River <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;hydrograph&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;a graph depicting river flow over time&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>hydrograph<\/span> at Las Animas. Note that after the spike on July 27, the river has stayed well above normal levels for the better part of 3 weeks. The volume of 30-day rainfall that fell in the area that drains into the gage below is near record levels. Fortuitously and quite surprisingly, the rain was spread out in time just enough to limit major flooding concerns.
