It`s starting to feel a bit like fall! Breezy afternoon winds up to 25 mph can be expected areawide, locally higher (up to 30-35 mph) for Mono county. Temps drop 5 degrees below normal today, equating to mid-70s across much of W NV and the lower valleys of NE CA, and mid-60s across the Sierra. Similar temperatures prevail tomorrow with chilly morning lows (near freezing in the Sierra). A trough off the northern California coast today will track inland, bringing increased chances for rain and high mountain snow showers this evening and into Monday afternoon. Current radar shows a band of showers progressing over NE CA and into northern Washoe county. As that trough gets closer, those showers will move over the Basin and Range of W NV this afternoon. The heaviest precip will occur late tonight, primarily south of I-80, and will track southward through Monday morning. Rainfall totals will amount to 0.1" or less for the Basin and Range and Mono county. With snow levels around 9000 ft, the peaks of the White Mountains and the Eastern Sierra may see snow accumulations up to 1" (30-60% chance) by Monday afternoon. Smoke and haze from the Dome fire will continue to impact communities along US-395 from Walker to Bridgeport. However, as that trough progresses southeastward over California, our typical W/SW breezes will switch to N/NE Monday afternoon, helping improve air quality concerns. Fog remains a possibility for fog-prone Sierra valleys early Monday morning, which may bring visibility reductions. Remember to use your low beams and take it slow in areas of lower visibility. Tuesday and beyond, we warm up and dry out. Afternoon highs shoot back up above normal with light winds prevailing. Maybe summer wants to stick around... -Giralte && .AVIATION... VFR conditions for all terminals, with CIGS primarily above 10,000 ft today. A 10-30% chance of -RA for western NV sites after 06Z tonight. W/SW gusts of 25 kts continue today, locally up to 30 kts for KMMH. With gusty winds at FL100, localized mountain wave turbulence and LLWS is possible this evening, especially near and over the Sierra. -Giralte && .REV Watches/Warnings/Advisories... NV...None.
