901 FXUS65 KLKN 062202 AFDLKN Area Forecast Discussion National Weather Service Elko NV 302 PM PDT Tue May 6 2025 .SYNOPSIS...Fair weather thru Friday aside from a stray dry thunderstorm or two possible Friday afternoon in and near Elko and White Pine Counties. Stronger southwesterly winds over the weekend with continued low probabilities for thunderstorms. Temperatures under a warming trend thru the end of the week as well. Stronger push of rain showers expected next week in the Tuesday time frame as a cold front moves in from the northwest. && .SHORT TERM...Tonight through Wednesday night Meso low over the state this afternoon will continue to progress south and out of Nevada tonight, residing over SoCal by sunrise Wednesday. Light rain showers will follow suite, moving south in conjunction with the low, and dissipating thru this evening. Skies become mostly clear tonight as well, clearing from north to south. Surface winds trend light to calm. Overnight low temperatures will be in the upper 20s to upper 30s. Southwesterly flow moves into the state Wednesday as the upper pattern evolves. Showers observed the last few days will continue to migrate east in conjunction with the larger scale synoptic low that looks to be positioned over New Mexico Wednesday. Therefore showers will mainly be situated over the central Utah mountain ranges and further east with Nevada observing dry weather. That said, some numerical model solutions are indicating isolated showers across central Nevada Wednesday afternoon. Opting not to include showers in the forecast however given that PWATs are progged less than 0.40 inches which will not be enough to produce diurnally driven showers. Lack of any apparent upper forcing also not favorable for the production of showers. Cumulus build ups will be the only item of note. Generally light southwesterly winds in place Wednesday as well. Temperatures under a warming trend with daytime highs in the mid 60s to mid 70s. Overnight lows reside in the mid 30s to mid 40s. && .LONG TERM...Thursday through next Tuesday Ridging building into the SW CONUS Thursday and Friday will maintain zonal force aloft over the Great Basin. The weather pattern will be relatively quiet (save for some isolated convection Friday afternoon) over the state with afternoon highs forecast to be in the 60s and 70s both days. CAPE values over eastern NV in the 120-160 J/kg range coupled with sufficient LI values are set up to produce isolated convection mainly over Elko and White Pine counties Friday evening. PW values fall below what is needed for wet storms but dry convection is certainly possible. By Saturday the ridge and resident HPC propagate far enough eastward exposing the area to the highs western flank and southerly flow. Combined with the southerly flow of a slow moving upper level trough pushing onshore over the West Coast, weekend high temperatures will soar into the 80s both days threatening several record high temperatures around the region. A jet streak embedded in the trough axis pushing into the SW CONUS will reinforce gusty winds under an ever tightening pressure gradient Sunday. Current model guidance forecasts criteria level wind gusts (potential 50-55 mph gusts) over central and east- central NV Sunday afternoon as well as portions of Humboldt county. Monday the area is firmly under southwest flow as the slow moving system makes its way eastward. Moisture increases across the region Monday afternoon increasing cloud cover helping to lower hot afternoon highs back into the 60s and 70s. Gusty winds ramp back up Monday afternoon at and beyond criteria levels similar to Sunday as the gradient remains tight in the divergent portion of the oncoming trough axis. Model guidance keeps precipitation out of the forecast until late Monday night into Tuesday. The main wet weather day with this system will be Tuesday when the axis of the trough finally makes its way through the state dragging a frontal boundary with it. Current model output has CWA-wide rainfall accumulations in the 0.1-0.3 range as the boundary treks west to east through the day. Temperatures will fall back into the 40s and 50s Tuesday making for a cool, rainy day. By Wednesday morning the area resides in northwesterly post frontal flow as overnight lows tumble into the 30s behind the front. && .AVIATION...VFR conditions are expected at all terminals through Wednesday afternoon. CIGS near 4000-5000FT over eastern and east- central NV on Tuesday will ascend as a low pressure system over eastern NV pushes to the south. Intermittent showers over KELY through early afternoon will move out of the area by Tuesday evening. Wind gusts Tuesday afternoon at KTPH will increase to around 30KTs but will diminish after sunset. Skies across the region will clear out Tuesday night as the low moves further away from the area. Wednesday weather is calm with lighter winds forecast through Wednesday afternoon. && .FIRE WEATHER...Weather will be mostly dry thru Friday with minimum afternoon RH values generally residing around 15% or greater. Exception will be some of the valleys in and near FWZ 426 where values as low as 10% will likely be observed. Cumulus buildups along with a low probability for a diurnally driven dry thunderstorm or two in and near FWZs 438, 469, 470, and 425 Friday afternoon with atmospheric moisture content the limiting factor. Temperatures will be under a warming trend thru the week with highs in 80s by Friday. && .LKN Watches/Warnings/Advisories... None. && $$ 92/99/99/92
