362 FXUS65 KREV 200808 AFDREV Area Forecast Discussion National Weather Service Reno NV 108 AM PDT Sun Apr 20 2025 .KEY MESSAGES... * Warm and dry this Easter Sunday with continued lighter winds becoming breezy this afternoon. * This period of warmer and dry conditions will extend into the first half of this week with afternoon west breezes. * Gradual cooling with increased shower chances expected by weeks end into the weekend. && .DISCUSSION Easter Sunday will start off nice with fair skies and light winds, and for the most part less chilly as previous mornings. A short wave trough aloft passing over the region this afternoon will encourage more enhanced breezes that will continue into the evening. Further north across northeast CA closer to the OR border, this trough will possess enough forcing and mid-level moisture that brings around a 10-15% chance for some showers forming in more favorable higher elevation areas west of Highway 395. The light winds and mild temperatures this morning, however, will at least provide for a more enjoyable egg hunt. Although the wind gusts will be for the most part stay below advisory criteria around 25-30 mph, it may still be a good idea before this afternoon to anchor down more securely that bounce house or celebratory decorations. Highs today will reach into the low to mid 70s for valley locations, and 60s around Sierra valleys. Little will change for the first half of the upcoming week with daytime temperatures rising some 5-10 degrees above seasonal averages. Daytime highs will reach into the 70s for western NV, and 60s for Sierra valleys. Overnight lows will drop into the 40s for Although winds will stay light in the morning with westerly breezes gusting to near 20-25 mph during the afternoon hours that dissipates about an hour after sundown. An upper trough will push the trailing edge of a cold front across northern CA-NV late afternoon and evening Tuesday will assist in not only enhancing west-southwest breezes, but also increase isolate shower chances across the northern Sierra north of the Lake Tahoe basin to the OR border. Later in the week into next weekend, ensemble simulations continue to spot light a trough pattern deepening into the western US. Although ensemble cluster analysis are showing some consistency with regards to anomalous upper height falls across the region late in the week, trajectory and relative storm system strength issues need to be resolved before a more certain forecast call can be made. More recent multi-model ensemble simulations are trending slightly drier as well with ECMWF-Ens guidance leading the way towards this solution. Nevertheless, guidance is pointing towards a cooler and more unsettled pattern across the Sierra and western Nevada by in the upcoming week. -Amanda && .AVIATION... VFR conditions will prevail for main TAF terminals through Monday with continued fair skies and breezy westerly afternoon wind gusts. Look for enhanced breezes this afternoon-evening with afternoon gusts near 20-25 knots for Sierra and WRN-NV terminals. Mountain ridgetop winds at or above FL100, where winds aloft increase to near 30-40 knots into this evening, will produce periods of light to moderate turbulence along and east of Sierra Crest. -Amanda && .REV Watches/Warnings/Advisories...
