036 FXUS65 KLKN 071015 AFDLKN Area Forecast Discussion National Weather Service Elko NV 215 AM PST Thu Nov 7 2024 .SYNOPSIS...Dry with temperatures trending warmer through the weekend. Valley rain and mountain snow is expected over portions of northern NV early on Monday, with precipitation reaching all of northern and central NV by Monday evening. Snow levels lower to most valley floors Monday night into Tuesday. In general valleys will see a trace to a half inch of new snow by Tuesday morning. && .SHORT TERM...Today through Friday night. Cool and dry northerly flow aloft persists across northern and central NV today, although temperatures are beginning to moderate. Lows early this morning will be in the teens to single digits which is around 10 degrees below normal. An upper level low currently centered over the four corners region will continue to weaken and eventually exit eastward as high pressure approaches NV from the west. As a result, the northerly flow over NV will weaken with highs this afternoon trending warmer by 5-7 degrees, with 40s to low 50s for most valley locations. Winds this afternoon will be light across northern NV, with gusts of 15 to 25 mph across central NV. The flow over NV continues to weaken Friday with a transition from a northerly to a southwesterly direction, which will help nudge high temperatures up to within a couple degrees of normal Friday afternoon, with 50s across the region. Winds will be light and variable on Friday, with continued dry conditions. .LONG TERM...Saturday through next Thursday An upper level low over the great plains combined with a trough off the Pacific coast will bring southerly flow and warmer air to the area on Saturday, leading to highs at or slightly above normal. Models indicate southerly or zonal flow continuing through Sunday, allowing temperatures to remain seasonal before that Pacific trough moves onshore and begins impacting Nevada. Trough impacts begin on Monday with gusty winds across the area (20-25 mph) beginning around noon and persisting until around midnight. Additionally, precipitation increase through the day, beginning in Humboldt county before sunrise and expanding south and east to cover almost the entire area by mid afternoon. Precipitation looks to be mainly rain while the sun is up, with snow levels in the 7-8 thousand feet range before transitioning to mainly snow overnight as snow levels will drop below 5000 feet in the north and around 5500 feet in the south. Precipitation begins to recede after sunrise on Tuesday as the trough shifts to our east, although some showers look to linger in the north until Tuesday evening. Temperatures will be noticeably cooler while the trough is overhead Tuesday, with most areas only reaching the 30s or 40s for daytime high temperatures. Overnight lows Tuesday night will also be significantly colder, with air temperatures in the teens and apparent temperatures dropping to single digits in places. Model accumulation guidance has been decreasing the past few forecasts, but confidence is still moderate for widespread accumulations of less than an inch of snow and significantly higher accumulations in the Ruby Mountains and Jarbidge Range, along with widespread qpf totals up to a quarter inch while those same mountains could see up to three quarters of an inch. Long term models indicate a shift to more zonal flow for Wednesday, allowing temperatures to begin to warm again, although current guidance shows temperatures still below seasonal. Wednesday also looks generally dry, although models show the potential for a few scattered showers still north of I-80. Thursday also looks warmer at this time but models are beginning to indicate another trough just outside of this period. Forecast confidence is currently very low but there are trends suggesting another weather maker at the end of the forecast period. && .AVIATION...VFR conditions expected at all terminals over the next 24 hour period, with wind gusts up to 20-25 kts for the central terminals KELY and KTPH, light winds everywhere else. && .LKN Watches/Warnings/Advisories...None. && $$ 96/94/92
