Area Forecast Discussion National Weather Service Las Vegas NV 240 PM PST Sat Feb 1 2025 .SYNOPSIS...Windy conditions will develop continue through this evening across the Western Mojave Desert and Sierra region as an active storm track develops across northern California. Breezy conditions will expand in coverage through early next week with mild temperatures. Rain and very high elevations snow chances will spread into the Southern Great Basin and Owens Valley Tuesday onward. && .DISCUSSION...through next Saturday. A strong low pressure system is churning off the coast of the Pacific Northwest/British Columbia, helping to channel moisture into central and northern California. The Sierra will intercept most of this moisture with a 20 to 30% chance that the Owens Valley will see some precipitation spill over later this afternoon and this evening. Any precipitation that does spill over will be relatively light with higher end totals of a few hundredths possible. High snow levels will limit snow accumulation to elevations above 9,500 feet in the eastern Sierra slopes. As we find ourselves sandwiched between the aforementioned system to our north and an area of high pressure to our south, we will see higher 500 mb heights build over the Desert Southwest today and tomorrow, allowing for the gradual warming trend of the past few days to really take off with temperatures 10+ degrees warmer than normal as we head into next week. In addition to rising temperatures, these rising heights will result in an increasing pressure gradient which will cause westerly winds to pick up across the eastern Sierra and northern Mojave Desert. Downslope winds will be possible in the Owens Valley this evening and again tomorrow, which would result in gusty cross winds across Highway 395. Precipitation chances will lull on Sunday and Monday before we see them begin to creep back up as another round of atmospheric river moisture takes aim at the area with 20 top 40% chances of precipitation across Inyo County and the southern Great Basin. If you are waiting for Las Vegas's streak of consecutive days without measurable precipitation to come to an end, don't hold your breath. Precipitation chances and QPF amounts across Clark, San Bernardino, and Mohave counties have been trending down over the past few iterations of the forecast as ensemble members have begun to converge on a solution with favoring a further north track with the Sierra intercepting most of the incoming moisture. Outside of increased precipitation chances for portions of our forecast area we will see temperatures cool down as 500 mb heights start to fall. Additionally, we will see periods of breezier southerly-to-southwesterly winds during the middle of the week. && .AVIATION...For Harry Reid...Winds through Sunday afternoon will be light, generally following diurnal wind patterns. However, by late afternoon, winds will shift to the southwest and begin increasing, with winds expected to peak late Sunday evening into Sunday night. Currently, there is a 25% probability for winds to exceed 10KT sustained between 22-00Z Sunday evening, increasing to upwards of 50% probability by 03/06Z. Initially, gusts are expected to be intermittent, however gusts to 15-20KT become increasingly likely late in the forecast period. Otherwise, VFR conditions will prevail, with passing high clouds yielding no impact to aircraft operations. For the rest of southern Nevada, northwest Arizona and southeast California...Light winds following diurnal wind patterns are expected at KVGT, with similar conditions at KHND. However, a southwesterly wind shift will arrive at KHND between 19-21Z, with winds becoming elevated and at least intermittently gusty thereafter. At KBIH, winds are progged to become elevated and gusty this afternoon, with gusts to around 20KT expected. Wind direction will generally remain northerly, before backing to the west to northwest late this evening. There is uncertainty regarding winds moving down the eastern slopes of the Sierra and across the Owens Valley overnight into Sunday morning, however for now, confidence was too low to include mention of gusts. Thus, will continue to monitor trends through this evening. At KDAG, westerly winds will be gusty through at least late this evening, with gusts to around 30KT this afternoon decreasing to 20KT this evening. Gusts will diminish there with sustained speeds dropping to around 10KT after midnight. KEED and KIFP will see light and variable/diurnal winds through early Sunday afternoon, with southerly winds becoming elevated thereafter as sustained speeds climb to 10-12KT. VFR conditions with high clouds will prevail areawide. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Stessman AVIATION...Phillipson For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
