Area Forecast Discussion National Weather Service Las Vegas NV 249 AM PDT Thu May 25 2017 .SYNOPSIS...Troughing moving in from the north will bring some relief from the heat of the past couple of days...especially by Friday...but expect today to be another breezy to windy day. Mostly clear conditions and lighter winds are forecast for the Memorial Day weekend with temperatures steadily climbing Sunday and Monday. && .SHORT TERM...Today through Saturday night. Troughing moving in from the north will bring some relief from the heat we've experienced the last couple of days. High temperatures are expected to fall off 5-7 degrees today...moving us back towards normal. Winds are expected to be on the windy side similar to what we experienced yesterday which means some local areas could see winds exceed advisory criteria this afternoon however widespread advisory level winds are not expected and no advisories are currently in effect. Additional cooling is forecast for Friday and Saturday with troughing continuing to influence the area weather. Expect sunny conditions and near to slightly below normal temperatures both days. Lighter winds will usher in the unofficial beginning of summer. .LONG TERM....Sunday through Wednesday. High pressure is expected to be the main player Sunday and Monday with above normal temperatures along with mostly dry conditions. Although we will see some off and on breezes both days, wind is not expected to be much of a factor. We will start to see a few changes Tuesday and Wednesday as weak low pressure moves down the southern California coast and undercuts the high. The GFS is much faster initially with this low and places it near northern Baja by Tuesday morning while the EC keeps it further north closer to San Francisco. With the further south run of the GFS it starts to tap into lower and mid level moister and wraps it back into northern Mohave County. GFS is also showing increased instability with LI values around 0/- 2. Based on the GFS it does look like the moisture would be deep enough to generate a few isolated thunderstorms over northern Mohave County. However, the EC is much slower and most of the moisture remains generally over eastern Arizona. By Wednesday, the EC shows the low near northern Baja and does start to tap into some of that moisture and wrap it back to the northwest which is also fairly close to the GFS solution. Although the models are rather far apart on Tuesday did go ahead and add pops for northern and central Mohave County and again on Wednesday since the models are in a little better agreement. Temperatures are not expected to be impacted much in the extended with readings a few degrees above normal. Some residual moisture will remain over the Sierra for at least a slight chance of showers/storms over the highest peaks each afternoon. && .AVIATION...For McCarran....Expect to see some dropoff in wind strength this morning before southwest winds increase again this afternoon. Sustained winds should be in the 17-24 knot range with gusts up to 35 knots possible at times. For the rest of southern Nevada, northwest Arizona and southeast California...Mostly clear skies today with Breezy to windy conditions across the region by this afternoon. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to provide reports according to standard operating procedures. && .FIRE WEATHER...Although temperatures will be several degrees cooler today...overall conditions will remain hot and dry. With gusty winds forecast to be around 35 MPH again this afternoon across Clark and Mohave counties, critical fire weather conditions are once again enhanced and a Red Flag Warning will be issued to highlight the potential for rapid fire spread. SHORT TERM/AVIATION...Salmen LONG TERM...Gorelow For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
