245 FXUS65 KLKN 182040 AFDLKN Area Forecast Discussion National Weather Service Elko NV 140 PM PDT Tue Jun 18 2024 .SYNOPSIS...Another cold, but not quite as cold, night is expected tonight with lows dropping into the 30s with areas of frost developing. Quiet weather with warming temperatures are expected through the rest of the week with some cloud cover each day through Friday with relatively cloud free skies through the weekend. && .SHORT TERM...Tonight through Wednesday night Benign, cool conditions are expected this evening with another cold night in store for many valleys across the area with lows dropping into the mid 30s to lower 30s mainly across Elko county, White Pine county and southern Lander/Eureka Counties. Temperatures continue an upward trajectory Wednesday with highs reaching into the 70s to lower 80s in some valleys farther west and south. An afternoon breeze from the south will develop across central Nevada of around 15 mph but lighter winds expected elsewhere. Frost threat Wednesday night will be absent with lows climbing back up into the 40s area wide. .LONG TERM...Thursday through Tuesday A trough axis just west of the Great Basin region will provide for a few mid and upper-level clouds Thursday and Friday. However, the overall dry southwest flow aloft will prevent any significant moisture intrusion from the tropical disturbance in the Gulf of Mexico into eastern Nevada on the western periphery of an expanding ridge of high pressure across the eastern U.S. Overall pattern will support warming temperatures back to above normal levels by the weekend with highs in the 90s with some upper 90s. Conditions will be quite dry near the surface with single digit RH values each afternoon but relatively light winds through at least Saturday before slightly higher west winds develop early next week. && .AVIATION...VFR conditions and light winds, less than 10 knots sustained, are expected at all TAF sites through Wednesday. A few mid-level clouds across northern Nevada will dissipate this evening. && .FIRE WEATHER...Benign fire weather conditions are expected through tonight with light winds and mild temperatures. However, a very dry air mass is now in place across central and northern Nevada with daytime relative humidity falling into the single digits by Wednesday afternoon. A afternoon breeze from the south will develop in higher terrain across central Nevada Wednesday but will remain well below thresholds. A steady warming trend will occur through the weekend with above normal high temperatures in the 90s returning by Friday across most valleys. Some cloud cover is expected Wednesday through Friday across the state but shower and thunderstorm activity will remain east Nevada through the weekend. && .HYDROLOGY...Cold temperatures this morning have mitigated high elevation snowmelt in the near term along faster responding mountain streams such as Lamoille Creek. The mainstem Humboldt River near Comus will continue with elevated flows for the next several days but minor flood stage is not expected to be reached. Dry conditions are expected this week with a warming trend beginning Tuesday. The Humboldt River near Battle Mountain continues to recede and has fallen below action stage. Further flow declines are expected through the rest of the week. The Humboldt River at Comus is expected to continue to rise through midweek but remain in action stage before a declining trend starts late this week. Wildhorse Reservoir remains elevated and will remain in action stage for the next several days. && .LKN Watches/Warnings/Advisories...
