047 FXUS65 KLKN 220915 AFDLKN Area Forecast Discussion National Weather Service Elko NV 215 AM PDT Wed May 22 2024 .SYNOPSIS...Rain showers across portions of northern Humboldt and northern Elko counties today, along with a 15% chance of thunderstorms across northern Elko county. Westerly winds of 15-25 mph with gusts of 30 to 40 mph will impact the entire region today, with blowing dust and hazy skies possible later this afternoon and evening. && .SHORT TERM...Today through Thursday night. Jet energy dropping in from the northwest tonight is bringing increasing clouds to northern NV. By sunrise rain showers will begin across portions of northeastern Humboldt county as well as northern Elko county. Locations up near the Idaho border may see a tenth of an inch of rain today, with diminishing rainfall amounts across central Humboldt and Elko counties. Northern portions of the Ruby mountains and East Humboldt range in Elko county may see a light shower today, otherwise precipitation is expected to be confined to areas north of I80. Additionally, there may be just enough instability this afternoon and early evening to produce a handful of thunderstorms across northern Elko county. Gusty westerly winds will impact the entire CWA today, with speeds ranging from 15-25 mph and gusts of 30-40 mph. Showers taper off across northern NV this evening and overnight. Dry conditions are expected across the CWA Thursday and Thursday night as a weaker westerly flow aloft sets up across NV. .LONG TERM...Friday through next Wednesday. An upper trough is expected to move into the region Friday with a reinforcing upper-low moving into Idaho by Saturday. This is expected to bring increased chances for showers into central Nevada Friday with more widespread showers and gusty west- northwest winds accompanying a diffuse cold front for Saturday. Temperatures will remain mild however, rising into the upper 60s to 70s on Friday before dropping around 5 degrees Saturday for the northern portions of the state behind the cold front. Lows Friday morning will be quite cold, in the lower 30s across much of northeastern Nevada with a mix of 30s and 40s by Saturday morning as cloud cover increases across the area. High confidence exists for dry condtions early next week as a ridge builds over the area. Winds will be fairly light through Tuesday but southwest winds will increase by midweek with troughing slowly working its way back into the the western U.S. Temperatures will rise accordingly with a building ridge pattern with highs into the lower to mid 80s by Tuesday and lows in the 40s. && .AVIATION...VFR conditions expected for the next 24 hours at all terminals. Breezy winds from the W-NW expected to affect all TAF sites early Wednesday morning, increasing to 15-25 knots with gusts to 30-35 knots during the late morning to early afternoon. KEKO is AMD not SKED due to communication issue. && .HYDROLOGY...As high elevation spring snowmelt continues, many streams and creeks coming off snow covered terrain will experience elevated flows. This weeks cooler temperatures have slowed the rate of snowmelt, however elevated flows persist. Late this weekend and into next week as warmer temperatures return, expect flows on many creeks and rivers to rise again, possibly up into action stage. Wildhorse Reservoir is in action stage. Recent cooler temperatures are allowing the reservoir level to gradually lower, however the level is expected to remain in action stage all week. && .LKN Watches/Warnings/Advisories...None. && $$ 96/93/90
