Area Forecast Discussion National Weather Service Las Vegas NV 240 PM PDT Mon Jun 25 2018 .SYNOPSIS...An area of high pressure over the Desert Southwest will keep hot and dry conditions in place through Wednesday. A trough of low pressure will move across the western states Thursday and Friday leading to increasing southwest winds and temperatures pulling back several degrees going into the weekend. && .SHORT TERM...through Wednesday night. Little change in the weather can be expected through Tuesday night and the most noteworthy concern will be fairly dense smoke over northern Inyo and Esmeralda counties from the Lions Fire near Mammoth. According to the HRRR Surface Smoke forecast, more diffuse smoke will be observed over northwest San Bernardino County and also portions for southern Nevada and northwest Arizona. However, it should not be dense enough to mention in the forecast. Wednesday will see a moderate increase in winds as the leading edge of an incoming Eastern Pacific trough begins to influence the area. South- southwest gusts of 25-30 mph will be fairly extensive. High and low temperatures will stay fairly consistent before the downward trend develop the latter half of the week. .LONG TERM...Thursday through Monday. The strong high pressure that will bring the above normal temperatures early in the week will be shoved east as a trough pushes into the west coast. This will bring a cooling trend that is expected to last into the weekend. Temperatures are forecast to be right around normal with little in the way of clouds. With the approaching trough, southwest winds are forecast to increase Thursday afternoon across much of the area. Most places will see winds between 25-35 mph which will lead to fire weather concerns. Winds will be lighter across the area Friday with the exception of Mohave County where a few gusts over 30 mph will still be possible. Winds will be lighter over the weekend as the area will be sandwiched between high pressure off the coast and low pressure to the east. && .AVIATION...For McCarran...Mostly clear conditions, except for some diffuse smoke from distant wildfires, will continue through Tuesday with high temperatures around 108-110. A south-southwest component around 10 knots will occur in the evening and overnight hours. East- southeast wind components occasionally gusting around 15 knots can be expected during the afternoon hours. For the rest of southern Nevada, northwest Arizona and southeast California...Smoke from a wildfire in the Sierra Nevada will affect flight visibility across Inyo County. Otherwise, no weather or significant clouds expected. South to southwest winds around 20 knots during the afternoons, with lighter winds overnight. No weather or significant clouds expected. && .FIRE WEATHER...Elevated fire weather conditions can be expected by Wednesday afternoon as a Pacific Trough begins to move inland. South-southwest gusts of 25 to 30 mph will be fairly extensive across the region Wednesday afternoon with single digit relative humidity values. Critical Fire Weather conditions are a concern across much of southern Nevada and northwest Arizona by Thursday afternoon as the trough moves inland potentially leading to extensive gusty southwest winds 30 to 40 mph. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM/AVIATION/Fire Weather...Adair LONG TERM...Gorelow For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
