343 FXUS65 KVEF 140758 AAA AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV Issued by National Weather Service Reno NV 1258 AM PDT Wed Aug 14 2024 .SYNOPSIS...The region will be dry with temperatures running 2 to 5 degrees above normal through Friday. Shower and thunderstorm chances return this weekend as monsoon moisture increases into southeast Nevada, northwest Arizona and the eastern Mojave Desert of California. && .SHORT TERM...Through Friday night. A series of perturbations passing by to our north through Thursday will keep the subtropical ridge axis suppressed to our south. South to southwest breezes will persist with gusts 20 to 30 mph at times. On Friday, south to southeast flow on backside of high pressure centered to our east will begin to open the door for monsoon moisture and increasing storm chances this weekend. .LONG TERM...Saturday through Tuesday. Heading into the weekend, a trough of low pressure will approach the West Coast, which will alter the synoptic pattern aloft. The Mojave Desert will be sandwiched between the aforementioned trough and a ridge of high pressure over the Central United States. This will result in a south-southwesterly flow aloft, which will allow monsoonal moisture to funnel up the Colorado River Valley into the forecast area. As such, precipitation chances increase Saturday afternoon and return each afternoon through Tuesday. Highest precipitation chances will exist over northwestern Arizona and the mountains of southeastern Nevada with uncertainty remaining for areas west. && .AVIATION...For Harry Reid...South-southwest components will persist through this afternoon. Wind speeds through 19z will generally be around 8-12 knots with isolated gusts to around 18 knots. Southwest winds will increase to around 10-15 knots with gusts to around 20 knots after 19z. Skies will remain clear. For the rest of southern Nevada, northwest Arizona and southeast California...South-southwest winds 10-15 knots can be expected across much of the region through this afternoon.
