375 FXUS65 KREV 170943 AFDREV Area Forecast Discussion National Weather Service Reno NV 243 AM PDT Mon Jun 17 2024 .SYNOPSIS... * Gusty north winds across Mono County and western NV today with choppy lake waters and localized critical fire weather conditions in receptive fuel beds across Mineral County. * Frost and freeze potential mainly for Sierra valleys tonight into Tuesday morning. Coldest rural Nevada valleys could approach freezing. These temperatures are 15 to 20 degrees below season averages. * Temperatures return to season averages midweek before heating to the mid 90s to near 100 in lower elevations this weekend. && .DISCUSSION... -Brisk North Winds Today: * A cold front will continue to track south across Nevada leaving brisk N-NW winds in its wake this afternoon. The surface gradient will be most pronounced across the W.Nevada Basin and Range where sustained winds of 20-30 mph will be possible along with gusts of 30-40 mph. * This will result in rough boating conditions across Basin lakes such as Pyramid, Walker, Lahontan, and Rye Patch Reservoir as well as eastern Sierra lakes including Crowley Lake. As such, a Lake Wind Advisory has been issued for these winds. Areas of blowing dust possible downwind of desert sinks. * Localized areas of critical fire weather conditions will still be possible, particularly in any areas of cured fine fuels across far W.Nevada basins and in the Chalfant Valley. -Significant Cooldown Today and Tuesday: * Our recent cold front will usher in a much cooler air mass with today`s high temperatures struggling to reach the 70 degree mark across W.Nevada (15-20 degrees below season averages). * Clearing skies, very dry air, and decreasing winds will allow for temperatures to fall to chilly levels overnight. Sierra valleys and even some colder lower valley such as the Carson and Smith valleys have a 40-60% chance of seeing several hours of freezing temperatures. Consider protecting sensitive plants tonight and early Tuesday morning if you live in a cold valley. -Heating Up By the Weekend: * Temperatures will quickly rebound 5-10 degrees on Tuesday with near average temperatures expected by Wednesday afternoon. * While this week will start off 15-20 degrees below season averages, the weekend is looking to heat up to 10-15 degrees above average. This will put W.Nevada valley in the upper 90s to near 100 with mid-80s for Sierra valleys. * Precipitation prospects looked limited through much of the upcoming week with a dry air mass in place. However, increased heating by the weekend could result in cumulus development across elevated terrain with overall shower chances less than 10%. Fuentes && .AVIATION... * A cold front will work its way across western Nevada and the eastern Sierra today with northerly winds settling in behind the front.

LLWS and areas of BLDU possible at times. * Sierra and Sierra Front terminals will see lighter northerly sustained winds of 10-15 kts.
