NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jan 6, 12:07 PM PST, 6 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 1207 PM PST Sat Jan 6 2024 .SYNOPSIS...A cold and unsettled weather pattern is in store for the upcoming week. The first in a series of weather systems arrives over the weekend bringing winter weather conditions to the Sierra and isolated to scattered showers and blustery conditions elsewhere. Below normal temperatures will continue through next week with more unsettled weather possible by the middle of the week. && .DISCUSSION...Through next Saturday. Dynamic, cold trough rolling south through the PacNW into northern California/Nevada early this afternoon. Western Nevada and eastern Sierra Slopes of Inyo/Mono Counties already getting the gusty southwest-west preceding the cold front. By late afternoon, those stronger southwest-west winds will start to surface across the southern Great Basin, Mojave Desert and northwest Arizona. The strong winds will continue across the Mojave Desert and northwest through the night. Meanwhile for Inyo County and southern Nevada, blustery north winds behind the strong cold front will develop overnight. Those blustery north winds will continue through Sunday before starting to abate some Sunday night. The wind advisory may need to be extended into Monday for the Lake Mead Natl. Rec Area and lower Colorado River. Will hold off on the extension at this time and wait as more hi-res data falls in the Monday timeframe. As for precipitation, there is the higher area of QPF moving down the west side of the southern Sierra, lighter amounts for the Great Basin/Mojave Desert and finally heavier QPF over northwest Arizona. QPF values across northwest Arizona continue to increase with each new model run. Based on latest guidance am going to issue a Winter Weather Advisory for southern Mohave County, above 4000 feet from midnight - 11 am MST Sunday. Looking at 2-5 inches, this will mesh well with our northern Mohave County and adjacent winter weather products in Coconino and Yavapai Counties. For the eastern Sierra Nevada of Inyo County, higher snow rates will develop later this afternoon and continue through the evening as main area of precipitation moves down the west side of the southern Sierra. Expect snow rates to tapper off after midnight. Finally for the Great Basin/Mojave Desert. Most of the precipitation will start off as snow, expect for the lower valleys of Clark, San Bernardino and far wester Mohave Counties. But, even that will eventually transition over to a mix of rain/snow or all snow late tonight through Sunday morning as snow levels plummet to 1500-2000 feet (H7 Temps -12-14 deg C). With QPF amounts of only a few hundreths forecast this should only produce a dusting for the lower valley floors, and 1-3 inches for the Spring Mountains. Additional upcoming hazards that will need to be determined are potential first freeze of the season for the lower Colorado River Valley Tuesday morning and a Hard Freeze for Kingman(Southern Mohave County) Monday and Tuesday mornings. There remains some model uncertainty mid-late week regarding timing/depth of shortwaves darting southeast through the Great Basin in active/progressive northwest flow. For simplicity, continued cold, periods of gusty winds at times, with best chance of light showers Wednesday and Thursday. .AVIATION...For Harry Reid...Expecting light winds favoring the east or southeast for the first part of the afternoon. Most likely, winds will become south and increase to 8-10KT around 00Z. If this does not occur, light east to southeast winds will continue into the early evening. Clouds 15kft-20kft will increase through the afternoon. High confidence for gusty winds tonight and Sunday. Southwest to west winds will quickly jump later this evening around 03Z. There is a high probability (80% or greater) for gusts 30KT or greater tonight 04Z through 09Z, and a moderate probability (40%-60%) for gusts over 35KT. The strongest winds should be 06Z-09Z when gusts to 40KT are not out of the question (10%-30% chance). After 09Z, winds will become more west to northwest and decrease slightly. This is also when scattered showers may move through the area. The best chance for precipitation will be in the mountains to the west, and mountain obscuration is likely through early Sunday morning. There is a low chance for showers to move over the terminals- if they did, expect CIGS to 5000-7000ft and light rain. Otherwise, CIGs to 10kft are likely tonight. Winds may become light with precipitation moving through, so expect winds to bounce up and down with the precipitation potential. Showers will exit the area early Sunday morning after 15Z. In its wake, expected rapidly improving CIGs but gusty northwest winds. These northwest winds should not be as strong as the overnight southwest with gusts to around 30KT Sunday morning through the afternoon. For the rest of southern Nevada, northwest Arizona and southeast California...Light winds and dry conditions are expected this afternoon. Increasing winds are likely across the region after 00Z and through much of the TAF period. West winds at 10-15KT will become gusty out of the northwest this evening with gusts to 20KT possible by 03Z. However, scattered showers are also possible in and around KBIH after 03Z. Winds may become light if precipitation moves over the airport, then become breezy again once precipitation ends. THe best chance for snow at KBIH will be 03Z-09Z with CIGs down to around 5000ft and visibilities 3-5SM with any snow showers. Scattered precipitation will move away from KBIH after 09Z but quickly transition south through the rest of the region late tonight through Sunday morning. The best chance for precipitation will be in the higher terrain, with light showers and CIGs 6000-8000ft possible elsewhere in the valleys. Low chances for precipitation near KDAG 09Z-14Z, then at KEED/KIFP 10Z-15Z. Gusty west to northwest winds this evening and early tonight will become northwest behind the precipitation by Sunday morning across the region. The strongest winds will be at KDAG with westerly gusts 30-35KT possible this evening through early Sunday morning before becoming more northwest and decreasing to 15-20KT by 15Z. KEED and KIFP will see their strongest winds with the northwest winds Sunday morning after sunrise with gusts 25KT-30KT possible. CIGs will quickly improve behind the exiting precipitation Sunday morning. && .SPOTTER INFORMATION STATEMENT...Reports of heavy snowfall... visibility reductions...and strong wind gusts are encouraged as a quick moving weather system moves through. && DISCUSSION...Pierce AVIATION...Nickerson For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
