Area Forecast Discussion...CORRECTED National Weather Service Las Vegas NV 139 PM PST Tue Feb 4 2025 .SYNOPSIS... An approaching winter storm will produce heavy snow across the Eastern Sierra late this afternoon through Wednesday morning, with a second round Thursday into Friday. Significant snow accumulations are expected above 8000ft, with periods of light rain showers expected across adjacent portions of Inyo County and the southern Great Basin through Friday. Breezy to windy conditions also continue, especially across Inyo, southern Nye, and western Clark Counties, persisting through Wednesday. Temperatures through the remainder of the week will undergo a gradual cooling trend, finally dropping to near and slightly below normal this weekend into early next week. && .SHORT TERM...through Wednesday night. Another unseasonably warm, breezy to windy day is underway across southeastern California, southern Nevada, and northwestern Arizona. After multiple near record and record high temperatures yesterday, a repeat looks to be on tap this afternoon, as Las Vegas has already officially reached 77 degrees, eclipsing the record high of 76 degrees set back on February 4, 1953. These unseasonably warm temperatures are in large part thanks to persistent southwesterly flow aloft and deep mixing resulting in compressional warming across much of the area. This is also resulting in continued breezy to windy conditions, especially across Inyo County with winds also ramping up across and downwind of the Spring Mountains into western Clark and southern Nye Counties. Wind Advisories remain in effect for the aforementioned areas this afternoon, continuing into this evening for Inyo County and through Wednesday for southern Nye and western Clark Counties. The primary areas of concern for winds through tonight are portions of Highways 395 and 136 in Inyo County where crosswinds and possible blowing dust could produce hazardous driving conditions, as well as Highway 95 between Indian Springs and Desert Rock where downsloping crosswinds off of the Spring Mountains have a 60-80% probability to exceed 50 mph this evening and tonight. Winds begin to diminish across Inyo County this evening, though will linger across southern Nye and Clark Counties into Wednesday. The other big story today is an incoming Winter Storm that will produce significant snowfall across the Eastern Sierra Slopes beginning late this afternoon through Wednesday morning, where a Winter Storm Warning remains in effect. Latest water vapor imagery and RAP analysis indicates a trough off of the Pacific Northwest Coast routing a fetch of Pacific moisture across northern California, which will sag southward as it translates eastward tonight, impacting mainly western Inyo County. On the west side of the Sierra, banded upslope precipitation has begun, though for the Sierra Crest and eastern slopes, latest high-resolution guidance indicates precipitation won't ramp up until early this evening. There has been very little change to forecasted snow totals across the mountain areas, with the greatest potential for significant snow accumulations above 8000ft, where 2 to 3 feet of snow are likely, with locally higher amounts expected across the Peaks. In Aspendell, there is an 80% chance to see snow totals exceeding 12 inches through Wednesday morning, with a 20-40% chance to see snow totals up to 18 inches. Of note, is the moisture associated with this system remains very shallow - largely below 500 hPa - and thus most of the moisture will be intercepted by the Sierra, with only light showers with little if any impact expected further east across Inyo County and the southern Great Basin as the moisture plume translates eastward. As previously mentioned, a cooling trend will be underway after today, with highs Wednesday expected to be around 5-7 degrees cooler than today for most locations. However, highs remaining in the 60s and 70s for lower elevations and 50s in most mountain areas aside from those impacted by snow will still remain around 10 degrees above normal. Wednesday will also be a relative lull in the active pattern this week as the initial system impacting the area moves east, with mainly dry conditions expected for most after Wednesday morning. .LONG TERM...Thursday through Monday. After the lull on Wednesday, the aforementioned low off of the Pacific Northwest Coast will move inland Thursday, accompanied by another moisture plume progged to bring round two of heavy snow to the Eastern Sierra. While the overall evolution of the pattern remains consistent, it has slowed down somewhat, with the bulk of precipitation now expected Thursday late afternoon/evening through Friday. An additional 1 to 2 feet of snow is expected in the Eastern Sierra, with the greatest amounts across the highest elevations, with a better chance of precipitation east of the mountains associated with not only the increased moisture but the enhanced ascent ahead of the approaching trough axis as it translates eastward into the Great Basin through Friday afternoon. While precipitation chances on the order of 30-60% are fairly widespread across northern and western portions of the forecast area, it's important to note that QPF remains paltry, generally under 0.05" for locations east of the Sierra. Thus, only spotty rain/snow showers with little to no tangible impacts are anticipated. Aside from precipitation chances, the cooling trend continues through the end of the week, though temperatures will still remain above normal through Friday. In the wake of the trough, Saturday will see sharply cooler temperatures closer to seasonal norms in the 50s and 60s for most and 40s in the mountains, which will carry through the weekend. Ensemble guidance remains in fairly good agreement regarding the evolution of the upper pattern into early next week, with quasi-zonal to northwesterly flow setting up over the western CONUS. However, disturbances/shortwaves within this flow will largely dictate sensible weather patterns, and remain uncertain. Thus, have currently maintained the cooling trend with temperatures near or even slightly below normal into early next week and dry conditions for most. && .AVIATION...For Harry Reid...Gusty southwest winds are likely through the afternoon, with a high probability (50 to 55 percent) for gusts over 25 knots and a 20 percent chance of seeing gusts to 30 knots. Winds will diminish some after sunset with gusts becoming less frequent after 3Z. Stronger downslope winds will persist overnight across the western edges of the valley. While the current forecast does not have these higher winds making it to the field, if they did, occasional gusts of over 25 could be expected through the night. Regardless of the overnight winds, gusty southwest will return Wednesday with a high probability (60 percent) of seeing winds over 25 knots again. Occasional high and mid-level clouds will move across the valley into this evening before decreasing overnight. Only a few non-impactful high clouds are expected on Wednesday. For the rest of southern Nevada, northwest Arizona and southeast California...Conditions at the Vegas Valley TAF sites will be similar to those described above at Harry Reid. A KBIH, gusty southerly winds will continue through the afternoon. By evening, moisture will begin to spill over the Sierra, possibly causing a few showers at the field. However, the majority of the precipitation will be confined to areas closer to the mountains where areas of reduced visibility can be expected. This increase in moisture should also help stabilize the atmosphere, reducing wind speeds during the overnight period. Winds Wednesday in the Owens Valley should remain southerly, although speeds should remain less than 20 knots. Skies will remain BKN to OVC into Wednesday morning, with CIGs potentially falling as low as 4kft AGL overnight and Wednesday morning. Skies should improve by Wednesday afternoon with skies scattering out and CIGs increasing to around 10kft AGL Elsewhere across the region, at KDAG, westerly winds will persist through Wednesday, with afternoon gusts over 25 knots likely each day. Winds in the lower Colorado River Valley will be south to southwest today and tomorrow. Gusts to 25 knots are likely today, but speeds should remain less than 12 knots on Wednesday. Occasional high and mid-level clouds will move across most areas into this evening before decreasing overnight. Only a few non-impactful high clouds are expected on Wednesday. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Phillipson AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
