NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Sep 1, 8:34 AM PST, 3 hours 56 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 934 AM PDT THU SEP 1 2016 .SYNOPSIS...Scattered showers and thunderstorms will develop primarily over northwest Arizona today through Friday while a few storms may brush southeast Nevada today. The rest of the region will experience dry and breezy conditions with a slight cooling trend. A dry southwest flow associated with a broad area of low pressure will persist over the Labor Day weekend with temperatures cooling a little below normal through early next week. && .UPDATE...First batch of storms looks like it should be mostly out of our CWA around 18Z, with more new development expected this afternoon. Grids look representative and no update planned this morning. && .PREV DISCUSSION... 325 AM PDT THU SEP 1 2016 .SHORT TERM...Through Friday Night. It appears things are shaping up to favor thunderstorms primarily over northwest Arizona today though some isolated showers or thunderstorms could develop over eastern Lincoln/northeast Clark counties and the Spring Mountains and Sheep Range. Recent mesoanalysis charts showed a tongue of PWAT of 1-1.25 inches extending up across northwest AZ and far southeast CA/NV. There has obviously been broad upward forcing with extensive cloud cover developing over Mohave County overnight due largely to convergent mid level flow and a curved upper level 60-70 knot jet which will remain in place through the day. Forecast soundings indicate a moderately unstable vertical profile under the aforementioned areas of moisture and we should see scattered thunderstorms result over much of Mohave County. Storm motion will generally be to the north- northeast 15-20 mph. Convection should continue well into the evening hours given the upper level dynamic support. The moisture boundary is forecast to only push slightly eastward through Friday and should still remain over the eastern half of Mohave County keeping the chance of thunderstorms confined to that area through Friday afternoon and early evening. The rest of the region will see dry and breezy conditions with temperatures dipping back to normal values as the broad west coast trough progresses slightly inland. .Long Term...Saturday through Thursday. A hint of autumn will be in the air during the extended period as a rather large trough is carved out across west keeping our region "cool" (By early september standards) and breezy. Afternoon high temperatures over the labor day weekend will average 4 to 8 degrees below calendar day normals. In addition to the cool temperatures, thermal gradients across the Great Basin will induce fairly breezy conditions especially across the Mojave desert, especially Saturday and Sunday. The combination of dry and breezy conditions may favor elevated fire danger during this period. Looking ahead into next week...dry conditions will continue with a gradual return to near normal temperatures. Beyond Wednesday...a tropical disturbance has been consistently advertised by forecast models to develop in the vicinity of the Baja and move northward, possibly inducing a moisture surge for the later portion of the week. Tropical influences in the extended range are notoriously fickle, so I have made few changes to the longer term grids at this time, but it will be something to keep an eye on. .AVIATION...For McCarran...Wind speeds will increase by late morning with a south-southeast component becoming more decidedly south by early afternoon with gusts of 20-25 knots through the early evening. Thunderstorms can be expected primarily in the Peach Spring corridor and in the Mormon Mesa corridor near the Utah border this afternoon and evening. For the rest of southern Nevada...northwest Arizona...and southeast California...Gusty southwest winds will expand in coverage across much of the region today. Isolated to scattered thunderstorms will be confined to northwest Arizona and far southeast Nevada this afternoon and evening. .SPOTTER INFORMATION STATEMENT...Thunderstorms are expected to return to the forecast for at least Mohave County today through Friday. Spotters are encouraged to report significant weather according to standard operating procedures. && Update...Morgan Short Term/Aviation...Adair Long Term...Outler For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
