Area Forecast Discussion National Weather Service Las Vegas NV 1054 AM PDT Mon Apr 11 2022 .SYNOPSIS...A potent system diving in from the Pacific Northwest will bring widespread high winds and extensive blowing dust today. Winds weaken tomorrow, but usher in much cooler temperatures. Temperatures warm to near normal by the end of the week, before another system looks to bring breezy conditions. && .UPDATE...Start time for the high wind warning for the eastern Sierra and Owens Valley has been bumped up to the current time. This warning will remain in effect until 3 AM PDT. The wind advisory in southern San Bernardino County has been expanded to include southeastern San Bernardino County and southwestern Mohave County, including Needles and Lake Havasu City. && .SHORT TERM...Today. Water vapor satellite imagery shows a potent shortwave/compact closed low over the PacNW this morning. This system will continue to dive southeast throughout the day, inducing pressure falls over the Intermountain West. This will create a stout W-E pressure gradient, promoting strong west-southwest winds across the entire CWA. During this time, a 500mb jet max will be pivoting around the base of the trough, impinging on our area and setting the stage for strong downslope winds. Widespread wind gusts of 50-70 mph are expected, with locally stronger gusts possible with any significant downsloping in the Owens Valley and the west side of the Las Vegas Valley. Extensive blowing dust is expected, making for hazardous travel in some locations. High profile vehicles can also expect hazardous travel, especially on N-S roads where crosswinds are maximized. In the Las Vegas Valley, some hi-res guidance is suggesting the development of a rotor feature this evening, which would induce weaker, easterly winds on the east side of the valley. However, it remains unclear whether this feature will actually materialize, and if so, where it will set up. Regardless, everyone should prepare for very windy conditions this afternoon and evening. A cold front is expected to push through overnight, shifting winds to the northwest and bringing an end to the strongest winds. .LONG TERM...Tuesday through Sunday. As this system exits the region tomorrow, breezy northwest winds and much cooler temps will be left behind. Tomorrow's highs are forecast to be 50's and 60's for the majority of the CWA, 15-20 degrees below normal. Lows on Wednesday morning will range from the 20's in our northern locations to the upper 40's in the Colorado River Valley. Fortunately, temps will warm up throughout the week as zonal flow sets in. By Friday and Saturday, temps should be near their seasonal values. Ensemble guidance suggests that a late-week system may impact our area. There remains a fair amount of uncertainty with this system, but the main impacts, if any, look to be wind-related. && .AVIATION...For Harry Reid...Moderate to major impacts still expected today as high wind gusts begin to impact the terminal this afternoon. Winds have turned south-southeasterly this morning but will shift to the southwest by the 18-19Z time frame. Once this occurs, gusts will be strong, potentially eclipsing 50 kts at times and if so, warranting an airport weather warning. Highest winds expected in the 20-04Z time frame. Later tonight, a cold front will push through the valley shifting winds to the northwest around 07Z. Winds gusts will be lesser with the front, but still gusty, potentially as high as 40 kts as the front goes through. A gradual decrease in gusts is expected through the rest of the morning hours, but maintaining an overall northwest orientation. For the rest of southern Nevada, northwest Arizona and southeast California...KVGT and KHND will follow similar trends to KLAS with winds favoring a more southwesterly direction and sustained wind speeds and gusts increasing in speed throughout the afternoon. These winds will continue to increase throughout the afternoon with gusts at KHND and KVGT peaking around 45-50 knots between 20Z - 04Z. After 04Z, a cold front will move through and shift winds to the northwest staying gusty. Blowing dust and visibility reductions are expected to accompany this increase in wind speeds, especially for the KDAG terminal. Downslope west winds have begun at KBIH and will continue through the afternoon hours before shifting to the north around 01Z. These gusts could also be accompanied by blowing dust and potential reductions in visibility. Both KIFP/KEED locations could see 30-40 knot gusts this afternoon as well. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Woods AVIATION...TB3 For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
