First, the strong upper-level ridge that has been around for the last 48-72 hours is slowly weakening and will continue to weaken throughout the day. Meanwhile, a modest <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;shortwave&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;A disturbance in the mid or upper part of the atmosphere which induces upward motion ahead of it.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>shortwave<\/span> disturbance is entering the California coast. Weak lift and moisture convergence is enhancing mid-level moisture over the northern Great Basin.

However, most of this moisture is in the mid-levels and despite plenty of morning sunshine, instability will once again be limited today.<\/p>\n<p>Wrapping everything together, we expect an increase in shower and weak thunderstorm coverage today, especially over the higher terrain as the increase in mid-level moisture will help storms stay intact. However, with subsidence still being prevalent and only weak instability, expect a continuation of light to moderate rainfall rates. Thus, flooding is once again not expected today.<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2017\/08\/wv_markup-15.png\"><img loading=\"lazy\" class=\"aligncenter size-full wp-image-6169\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2017\/08\/wv_markup-15.png\" alt=\"\" width=\"636\" height=\"407\"\/><\/a><\/p>\n<h3><strong>Today&rsquo;s Flood Threat Map<\/strong><\/h3>\n<p>For more information on today&rsquo;s flood threat, see the map below (hover over threat areas for more details).
