NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jun 30, 9:54 PM PST, 2 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 1054 PM PDT THU JUN 30 2016 .SYNOPSIS...Monsoonal moisture that has spread up from northern Mexico will fuel thunderstorms across the Mojave Desert region... especially during the afternoon and evening hours through Saturday. Temperatures will trend downward due to the increase in cloud cover. Drier air is expected to work into the region early next week pushing monsoonal moisture east of the area. This will also allow for a warming trend with temperatures about 3 to 5 degrees above normal by Monday. && .UPDATE...Scattered showers and thunderstorms have increased over portions of Death Valley, southern Nye and extreme northern San Bernardino Counties this evening. This area had very little weather earlier in the day and instability is quite high in those areas. CAPE values are generally around 2000-3000 J/KG with LI's around -1/-3. Hail will be a concern with any storm this evening along with flash flooding. Upper level winds are fairly light and this will lead to slow moving storms. Thunderstorm activity is expected to last much of the night. .AVIATION...For McCarran...Erratic winds from several storm outflows have occurred this evening, making for a low-confidence forecast. However, trend seems to be for winds becoming light/variable overnight. Southeast winds expected to commence tomorrow with speeds around 10 kts. Chance of storms continues tomorrow, with best chances in the afternoon and evening. Potential air traffic impacts are substantial, with chances of convection at the terminal and in the flight corridors. For the rest of southern Nevada...northwest Arizona...and southeast California...Storms continue late this evening in Inyo, Nye, and San Bernardino Counties. Winds near storm outflows are gusty/erratic,while outside of these areas mostly terrain-driven and below 10 kts. Expect SE winds to develop tomorrow in most of the region with more chances of storms, especially during the afternoon/evening, with associated locally lower CIGs, reduced visibility, and convective turbulence. && .PREV DISCUSSION... 315 PM PDT THU JUN 30 2016 .SHORT TERM...through Saturday night. Scattered to numerous thunderstorms have erupted over southern Nevada and northwest Arizona thanks to the influx of low level moisture we received this morning from a widespread push of southeast flow below 700 mb. Surface heating and a boundary associated with a disturbance moving from southeast Nevada into southwest Utah helped initiate and intensify the thunderstorms and we should see convection expand this afternoon and evening across southern Nevada and northwest Arizona due to boundary interactions. Convection will diminish overnight but probably not die completely due to the moist and unstable environment. Similarly moist and unstable conditions will exist over the same area through Friday so we can expect scattered to numerous thunderstorms Friday afternoon. Dry mid to upper level flow should help clear mid to high level debris clouds overnight and allow for full surface heating again Friday. Saturday will see a slight decrease in thunderstorm coverage from west to east as dry westerly flow starts to spread over southern Nevada. .LONG TERM...Sunday through Wednesday. Models remain consistent with Previous runs showing a significant decrease in moisture on Sunday followed by dry weather areawide Monday through Wednesday. Weak troughing passes through California Sunday and through Nevada Monday, turning the flow more westerly and flushing out the monsoon moisture from our area. This will eliminate rain chances, knock surface dewpoints back down into the 20s and 30s, and also allow temperatures to climb back to several degrees above normal. Longer range models hint at moisture possibly returning around the end of the week, but there is plenty of time to watch this. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather according to standard operating procedures. Flash flooding will be a concern with any thunderstorm today especially across Mohave, Clark, and eastern San Bernardino Counties. && Update...Gorelow Short Term...Adair Long Term...Morgan Aviation...Shafer For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
