Area Forecast Discussion National Weather Service Las Vegas NV 217 PM PDT Thu Sep 5 2019 .SYNOPSIS...Shower and thunderstorm chances diminish tonight through Friday as the region begins to dry out. Drier and cooler weather along with afternoon breezes expected next week. && .DISCUSSION...through Wednesday. Monsoonal moisture and associated shower and thunderstorm chances will give way to fire weather concerns as cooler, drier air arrives for next week. The focus for today's thunderstorm chances has been a upper-level disturbance moving north across the region. Although leftover shower and thunderstorms from last night has resulted in abundant cloud cover, lift has been sufficient to continue to generate shower activity in southern Inyo and Nye, as well as Clark counties. Instability looks modest, even in areas that are receiving sunshine - with CAPE values generally 500 to 1500. Downdraft CAPE is around 1500, and storm motion is 15 to 20 knots to the north. Given these parameters, expect only brief periods of heavy rain with storms that do get going, with strong outflow winds the primary threat. As flow begins to shift southwesterly in response to an upper- level trough of low pressure coming onshore into the PacNW, expect drying conditions, with showers and thunderstorms limited to northern Mohave and Lincoln county for Friday. Another upper- level trough follows for Saturday into Sunday, and another for midweek next week. These will result in cooler temperatures and afternoon breezes. && .FIRE WEATHER...Scattered showers and thunderstorms across the region today will become more limited on Friday. A series of low pressure systems will begin to dry the area out over the weekend. While cooler temperatures are expected, dry air and afternoon breezes will begin to elevate fire weather concerns over the weekend into much of next week. && .AVIATION...For McCarran...Southwest winds are expected to continue through much of the afternoon, generally remaining below 10-12 knots. Low confidence on the forecast this afternoon, but some isolated to scattered showers and thunderstorms will be possible through the afternoon and early evening in and around the Las Vegas Valley, which could impact corridors to the southeast and southwest. With stronger showers and thunderstorms, gusty outflow winds will be possible which could impact the terminal. Outside of outflow winds, winds are expected to remain from the south-southwest through the overnight period. Only slight chances of a storm or two will be possible mainly along the higher terrain tomorrow and a typical valley wind pattern is expected. SCT to BKN aoa 10-12 kft will be possible through much of tomorrow. For the rest of southern Nevada, northwest Arizona and southeast California...Low confidence on the forecast this afternoon, but some isolated to scattered showers and thunderstorms will be possible through the afternoon and early evening across much of the region. Slightly better chances for showers and storms to impact KBIH, KDAG, and KIGM this afternoon. With stronger showers and thunderstorms, gusty outflow winds will be possible which could impact nearby terminals. Outside of outflow winds, winds are expected to follow typical diurnal patterns, favoring a south- southwesterly direction in the afternoon. SCT to BKN aoa 10-12 kft will be possible through much of tomorrow. && .SPOTTER INFORMATION STATEMENT...Scattered thunderstorm activity is likely today. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Steele AVIATION.....Kryston For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
