High temperatures were on the rise as the ridge continued to strengthen, and afternoon temperatures reached 1 to 5F higher than Wednesday. A little bit of moisture was present under the ridge (south) that originated from a disturbance over the Gulf of Mexico. This helped spark afternoon storms over the southern high terrains with the diurnal flow pattern. Steering flow fairly quickly from the NNE, a dry surface layer and small storm cores limited rainfall accumulation and kept storms mostly confined to the mountains. Storm totals (west) up to 0.30 inches were reported (Upper Rio Grande SNOTEL) and 0.11 inches east (La Veta Pass ASOS). Further north, storms produced less than 0.10 inches. Storms began to wane and fade away just after sundown.<\/p>\n<p>Rather than rainfall, the main threat from storms were lightning and <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;outflow&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;A cool pool of air that results when a thunderstorm downdraft reaches the surface and spreads horizontally.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>outflow<\/span> winds.

A wall of dust extended from 19 miles southeast of Wolf Creek Pass to Alamosa near Blanca. The KLAS (Alamosa) airport ASOS recorded a gust of 35 mph and sustained winds just over 25 mph, which more than likely&nbsp;briefly dropped visibility to less than a mile.&nbsp;There&rsquo;s a&nbsp;picture of the dust wall from Wilt Chamberlain at 5:20PM on <a href=\"https:\/\/twitter.com\/CareTechBrian\/status\/1400602616992784386\"><span style=\"color: #0000ff;\"><strong><span style=\"text-decoration: underline;\">Twitter (click me)<\/span><\/strong><\/span><\/a>.

The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences.

Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas.
