Area Forecast Discussion National Weather Service Las Vegas NV 1221 AM PDT Mon Oct 28 2024 .SYNOPSIS...Low pressure from the Pacific will bring increased winds, much cooler temperatures, and chances for rain and mountain snow today and Tuesday. Quieter weather and below normal temperatures are likely Wednesday through Friday. && .SHORT TERM...through Tuesday night. Midnight satellite loop showed high clouds blanketing the region, with the back edge of the clouds just beginning to enter the far northwest zones. Surface obs showed southerly winds picking up, with gusts over 35 mph in the higher elevations of the northwest half of our CWA. In the windy spots, temperatures were 10 to 20 degrees warmer than 24 hours ago. The low pressure system which was off the central coast of British Columbia 24 hours ago was near Vancouver Island early this morning. As the trough axis sags southeast toward our area today, skies will clear out with the exception of mountain-enhanced clouds. Thus, boundary layer temperatures will warm and allow the atmosphere to couple, causing the increasing winds aloft to mix down to the surface. The Wind Advisory looks good, although downslope-enhanced winds on the east slopes of the Spring Mountains will need to be monitored. Farther north, high resolution models have come into better agreement on a band of enhanced precipitation affecting Lincoln county Monday night. Forecast precip amounts have risen from about a tenth of an inch to just over half an inch, with most of this falling while snow levels crash from 7000 feet to 5500 feet. The best chances for more than a couple of inches of snow should be above most of the populated areas and highways, with projected snow amounts of three inches or more lining up well with the 7000 foot contour. Hoisted a Winter Weather Advisory for this area. Lastly, as the low center moves away Tuesday night, skies will clear out and winds will diminish. This will set the stage for radiational cooling overnight, and with the colder air in place, the first freeze of the season for the Arizona Strip. Issued a Freeze Watch for this area. .LONG TERM...Wednesday through Sunday. Appears the period will stay on the cool, and potentially unsettled side as ensembles simulations keep the region under the influence of a longwave trough as the calendar changes to November. However, there are differences in the handling of the final shortwave which is progged to possibly develop into a closed low in the general vicinity of southern California or northern Baja Mexico next weekend. Coolest day of the week will be Wednesday with highs about 10 degrees below normal. Temperatures recover some Thursday and Friday back closer to normal, before retreating several degrees over the weekend. There remains more uncertainty regarding precipitation chances. A more inland trajectory with that final shortwave would tend to be a drier scenario versus if it slides south closer to the coast allowing it to tap into moisture off the Pacific. && .AVIATION...For Harry Reid...South-southwest winds gradually increase through the morning hours, peaking in the late morning and afternoon. During the peak, gusts are expected to be in the 30-40 knot range, with a ~35% chance of gusts reaching 48 knots (Airport Weather Warning criteria). Winds are then forecast to slowly wane during the evening before the cold front and north winds arrive overnight. Wind direction may be a bit erratic at times after the front's arrival as winds swirl around the valley. Mid-level clouds clear out around daybreak this morning, leaving FEW-SCT high clouds around. Mid-level clouds return with the cold front while precipitation chances remain less than 10%. For the rest of southern Nevada, northwest Arizona and southeast California...Southerly/westerly winds increase during the morning hours, peaking in the late morning through early evening. The exception to this will be KBIH, where persistent northerly winds are also forecast to peak during that time. Wind gusts of 25-40 knots can be expected at all the area TAF sites this afternoon/evening, with the strongest values at KDAG. The present band of clouds should clear the area from NW to SE throughout the morning. Additional mid- level clouds accompanying the cold front will moves into KBIH in the late afternoon and the Las Vegas Valley late tonight. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM...Morgan LONG TERM...Pierce AVIATION...Woods For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
