NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Aug 30, 1:04 AM PST, 9 hours 56 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 204 AM PDT Wed Aug 30 2022 .SYNOPSIS...Hot temperatures and dry conditions will continue across most of the region into the Labor Day weekend as a dome of high pressure settles over the southwest. Temperatures may begin to moderate some over eastern areas during the second half of the weekend as monsoonal moisture flows back into Arizona. && .SHORT TERM...Today and Thursday. An amplified ridge of high pressure could be seen on satellite water vapor imagery over the western states and will be responsible for the prolonged heatwave which will persist into the holiday weekend for most of the region. The Excessive Heat Warning for the Mojave Desert Region remains unchanged. High temps today and Thursday should be a degree or two higher than those observed Tuesday. Central Mohave County remains borderline for Excessive Heat Criteria Thursday going into the weekend according to HeatRisk grids and the latest NBM forecast temps which indicate a slight decreasing trend for Kingman. This is apparently in response to a limited low-level moisture increase ahead of the wave currently over Texas/New Mexico which slowly moves to the west. Will keep an eye on trends the next 24 hours before deciding to extend the warning over the weekend for that area. .LONG TERM...Friday through Tuesday. Upper level ridge will stay firmly entrenched over the region through the holiday weekend and into early next week. Forecast high temperatures will be running 8-12 degrees above normal. Confidence is high in this prolonged heat wave with high to very high HeatRisk. Daily records; potentially some September monthly temperature records could be broken or tied. Otherwise, deeper monsoon moisture has been suppressed south across southern Arizona and New Mexico today. Models do show an inverted trough moving west around the southern periphery of the ridge across southeast Arizona and northwest Mexico Wednesday and Thursday. This could inject moisture back into northwest Arizona for increased storm chances Friday through the weekend, mainly over the higher terrain of southern Mohave County. && .AVIATION...For Harry Reid...Light winds under 8 knots favoring a southerly direction through the night then favoring an easterly direction around mid-day through sunset Wednesday. Little cloud cover is expected through the TAF period. For the rest of southern Nevada, northwest Arizona and southeast California...No significant weather is expected across the region today as a ridge of high pressure builds overhead. Winds throughout the period will be generally less than 10 knots and favor typical diurnal trends at all TAF sites. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM...Adair LONG TERM...Pierce AVIATION...Salmen For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
