The episode as NWS LKN wrote it up.
A dry thunderstorm developed across central Nevada and moved northward through the afternoon. The storm produced outflow winds over the Diamond Valley dry lake bed, which resulted in a dust storm. The dust storm moved into Elko and Spring Creek causing minor disruptions and impacts. The storm produced another dry microburst, resulting in a wind gust to 67 MPH in Elko and also produced minor damage throughout portions of town.

Area Forecast Discussion National Weather Service Elko NV 528 PM PDT Fri Apr 27 2018 .SYNOPSIS...Much above normal temperatures will continue today across eastern Nevada while cooler air will move into northwest Nevada. A storm system will bring cooler weather over the weekend to the entire area along with a chance of showers Sunday through early next week. && .UPDATE...Steady blowing dust from a dry lake bed has stopped thus advisory was allowed to expire. && .PREV DISCUSSION... /ISSUED AT 152 PM / SYNOPSIS...Much above normal temperatures will continue today across eastern Nevada while cooler air will move into northwest Nevada. A storm system will bring cooler weather over the weekend to the entire area along with a chance of showers Sunday through early next week. SHORT TERM...Today through Monday. Upper low off the northern CA coast will spread cooler air into northwest NV today while the rest of northern and central NV will continue to experience much above normal temperatures. A surface cold front pushing into northern NV will be the focus for thunderstorm development this afternoon. Not much in the way of moisture but with a fairly strong cold front and surface heating should see some isolated high based thunderstorms, mainly over Lander, Eureka, and Elko counties. Breezy to windy conditions today, especially across central NV, with south to southwest winds of 15 to 30 mph with gusts to 40 mph. The winds and outflows from showers and thunderstorms can cause blowing dust today which can lower visibility even drastically so. Once these storms die off this evening, mostly dry condtions will prevail through Saturday night as dry southwest flow moves across the area ahead of upper low. there still will be the chance for some convection along the NV, OR, and ID borders. As southern portion of upper low moves across northern NV on Sunday will see isolated to scattered showers, mainly across northern NV and isolated thunderstorms in the afternoon. The activity will begin to spread further south in the evening as low opens into a broad trough that sags further southward. Scattered rain and snow showers will linger across the region Sunday night through Monday night. Snow levels will lower into the 5000-6500 foot range both Sunday night into Monday morning, however little if any accumulation is expected even on grassy surfaces for most areas. LONG TERM...Monday night through next Friday. Another mid-level low will develop and pivot southeastward from Northern CA to southern NV Monday night into Tuesday. This storm track will be conducive to higher precip amounts south of the I-80 corridor. Snow will be likely in many valley floors Tuesday with a cooler air mass in place. Snow levels will range from 5500 to 6000 ft Tuesday morning but surface/road temperatures will be sufficiently warm to allow accumulations below 6000 ft. Some instability and dynamic forcing will remain over the state Tuesday with the best chances for thunder along and south of US-50. Lingering rain and snow will exit the region Tuesday night into Wednesday as ridging builds back over the Western US. Expect temperatures to moderate back into the 70s late next week accompanied by dry conditions. AVIATION...Southwest winds with gusts of 20-30kt range this afternoon will diminish after sunset for KTPH, KELY, and KWMC. Areas of blowing/suspended dust is possible through the early afternoon hours reducing VIS to around 1/2 miles at times at KEKO. In addition, afternoon TS is possible at KWMC, KBAM and KEKO. Gusty erratic winds can be expected with these storms before they diminish around sunset. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 99/99
