320 FXUS65 KLKN 182024 AFDLKN Area Forecast Discussion National Weather Service Elko NV 124 PM PDT Fri Sep 18 2026 .KEY MESSAGES... * Rain showers and isolated thunderstorms along the Oregon and Idaho borders, as well as the Utah border tonight and Saturday * Generally fair weather Sunday and Monday * Potential for rain across central Nevada for Tuesday afternoon && .DISCUSSION... (This evening through next Thursday) WEATHER PATTERN OVERVIEW: Upper level trough is currently tracking across northern Nevada this afternoon, as a result showers and a few thunderstorms have been ongoing over the Utah/Nevada border with a cool front over White Pine County, as well as with the main upper trough over the northern third of Elko and Humboldt Counties. The 20% to 30% chances for storms and showers associated with the cool front will push into Utah later this evening, however the 40% to 60% chance for showers and a few isolated storms with the main trough will persist through Sunday morning as the trough drifts east. Good news is winds will be much lighter than they have been over the last few days out of the W to NW at 10 to 20 MPH. Sunday and Monday look to be quiet days as shortwave ridging transits Nevada. Tuesday, the next upper level trough will move across the silver state, this time across central Nevada, and this system looks to move faster too, bringing a 20% to 40% chance for isolated to scattered showers and thunderstorms for the US 6 corridor Tuesday afternoon, departing Wednesday morning. Thursday another shortwave ridge transits Nevada with quite conditions. Friday and Saturday models are a bit different with possible solutions, as a trio of upper level features have the potential to make sensible impacts to NE Nevada, one is a Pacific upper trough, the second is a land falling Pacific tropical system whose remains will lift into the southwest US. Finally the last is the summertime subtropical ridge which may want to re-establish over the Great Basin. With all the possible interactions between these features shown in the ensembles forecast confidence is very low so will keep the period dry for now. Temperatures will be on a slow warming trend for the next several days, but nothing to drastic a afternoon highs rise into the mid 80s from the mid 70s, and overnight lows range in the upper 30s to upper 40s. FORECAST CONFIDENCE & DEVIATIONS: There is high confidence in a 20% to 40% chance for isolated showers and storms Friday for eastern Nevada. There is high confidence in a 20% to 50% chance for isolated to scattered showers and thunderstorms for northern Nevada Friday and Saturday. There is moderate confidence in a 10% to 30% chance for isolated to scattered showers and thunderstorms for NE Nye and southern White Pine Counties Tuesday afternoon. There is low confidence for the long range forecast as model solutions show a high degree of divergence for the upper pattern next Friday. && .AVIATION... VFR conditions look to be the primary flight conditions through Friday afternoon. Winds will be out of the W to NW at 10KT to 20KT with a few gusts up to 30KT across central NV. Upper trough and cool front will bring 20% to 40% chance for VCTS for KELY and KENV through the afternoon, and across the northern tier of N NV today and Saturday, but with the exception of KENV, I-80 terminals will remain dry. && .FIRE WEATHER... Elevated winds are ongoing, with the strongest gusts around 25 mph and centered in central Nevada. These will die off by late evening, leaving non significant afternoon breezes for the weekend. Isolated showers and thunderstorms are ongoing along the Oregon/Idaho and northern Utah borders and are also expected to persist through this evening. There is about a 10% chance of wetting rain with these storms. There is a small chance of isolated thunderstorms continuing for far northern portions of zones 469 and 470 on Saturday. All other areas will see a dry and fair weekend. && .LKN Watches/Warnings/Advisories... None. && $$ DISCUSSION...98 AVIATION...98 FIRE WEATHER...94
