Area Forecast Discussion National Weather Service Las Vegas NV 937 AM PDT Mon Jun 19 2023 .SYNOPSIS...Dry weather is expected for the upcoming week. However, strong winds will peak today as a deep area of low pressure settles over the Pacific Northwest. This low will keep temperatures below normal through the week. && .UPDATE...Not much change in forecast thinking, with gusty southwest winds developing across the region today. Most places in the Wind Advisories should see gusts of 40-50 mph, though the lee slopes of the Sierra and Spring Mountains could gusts up to 60 mph this afternoon and evening. Winds gradually weaken overnight but remain breezy tomorrow. Outside of the winds, cooler temperatures return as the system moves through. Another shot of winds and below-normal temperatures arrives Thursday before temperatures begin to creep up this weekend. Updated forecast package out this afternoon. && .SHORT TERM...through Tuesday night. Not much has changed in our forecast reasoning. Winds should be at their strongest today into this evening as surface pressure and thermal gradients increase over yesterday. All this is being driven by an unseasonably deep, cold trough over the PacNW, while the cold front will be draped across central Nevada and southeast California. Evaluating the H7 thermal gradient for peak gust potential at Las Vegas. Using a local study which looks at the H7 temperature difference between Medford, OR and Las Vegas would support gusts of 50-55 mph. Local gusts up to 65 mph still possible in the Spring Mountains from downsloping. Winds will slowly diminish overnight into Tuesday as support weakens as the cold front moves east into Utah/Arizona. Highs should be about 4-8 degrees cooler today, followed by another 3-6 degree dip on Tuesday. .LONG TERM...Wednesday through Sunday. West Coast trough will begin to reload midweek as another shortwave drops south along the West Coast. This wave will then pivot eastward Thursday with another breezy day expected areawide. Temperatures will remain below normal through most of the week thanks to the reduced heights under the influence of the trough. By the weekend, the West Coast trough will begin to weaken allowing an expansive subtropical ridge in northern Mexico to nudge northward. This will induce a gradual warming trend, with temperatures climbing close to normal by Sunday. && .AVIATION...For Harry Reid...Gusty southwesterly winds will prevail throughout the forecast period. Peak gusts for the remainder of the night through mid-late morning around 20 to 25 knots then increasing to 35 to 40 knots this afternoon and evening. Skies are expected to be mostly clear other than some passing high clouds. For the rest of southern Nevada, northwest Arizona and southeast California...The primary concern at area terminals through the TAF period is strong westerly to southwesterly wind gusts. Winds for the remainder of the night gusting 20 to 30 knots then intensify later this morning and continue into the evening with gusts 35 to 40 knots. Skies should be mostly clear with some passing high clouds at times except KBIH where SCT-BKN mid and upper level clouds are likely today before clearing tonight. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && UPDATE...Woods SHORT TERM...Pierce LONG TERM...Outler AVIATION...Salmen For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
