NWS Las Vegas, NV wrote its last area forecast discussion before the first event at May 28, 8:28 PM PST, 3 hours 32 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 928 PM PDT Mon May 28 2018 .SYNOPSIS...A warming trend can be expected Tuesday and Wednesday before a passing trough brings increasing wind Wednesday and Thursday and slight cooling for the end of the work week. This will be followed by temperatures climbing several degrees next weekend && .UPDATE...Clouds have mostly cleared out across Lincoln County this evening on the back side of the upper low lifting away across the Rockies. The PoP/WX grids were updated to remove evening showers and thunderstorms for Lincoln/northern Mohave counties. The rest of the forecast trends detailed in the previous discussion are on track. && .PREV DISCUSSION... 225 PM PDT Mon May 28 2018 .SHORT TERM...through Wednesday night. Still watching cumulus form and move south in the northerly flow on the back side of the departing low, but no lightning thus far, and if anything, vertical development may have decreased as the afternoon has worn on. PoPs are probably overplayed this evening, but cannot rule out a few storms before sunset. The current low will be long gone by Tuesday, and a weak trough will move in from the Pacific. This will lead to a slight chance of thunder near the Sierra crest in the afternoon and evening. Temperatures will jump about five degrees areawide as heights rise. Another trough digs down from the Gulf of Alaska into the West Coast Wednesday and Wednesday night, which will bring increased southwesterly breezes Wednesday, which will in turn bring improved mixing and the warmest day of the week. The forecast for KLAS is 100F. .LONG TERM...Thursday through Sunday. An open wave will progress eastward across the western U.S, including the local area, Thursday and Thursday night. Tightening gradients will lead to widespread, breezy conditions favoring the southwest direction. The strongest winds look to be north of Interstate 15 where a band of wind speeds near 30 mph gusting 40 mph will be possible Thursday afternoon. Precip will be limited to only a few showers across the higher elevations of Esmeralda County Thursday evening. Temps will also come down a few degrees with this system, closer to seasonal norms, but will begin rebounding Friday into the weekend back above normal. A weak shortwave will pass across the area early on Saturday ahead of the next longwave trough expected to make an entrance late this weekend. It appears that there will be little effect from these late week features in regards to precip or winds as dry conditions and lighter winds continue. && .AVIATION...For McCarran...Lighter winds are expected on Tuesday with more of a diurnal pattern. Should see east or southeast winds by Tuesday afternoon, but should remain below 10kts. VFR clouds at times through this evening becoming clear overnight. For the rest of southern Nevada, northwest Arizona and southeast California...Winds will decrease after dark and return to more typical diurnal wind directions. Lighter winds and dry weather are expected on Tuesday throughout the area. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report significant weather or impacts according to standard operating procedures. && SHORT TERM...Morgan LONG TERM...Guillet AVIATION...Wolf For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
