295 FXUS65 KREV 052031 AFDREV Area Forecast Discussion National Weather Service Reno NV 131 PM PDT Sat Jul 5 2025 .KEY MESSAGES... * Typical summertime warmth and dry conditions prevail this weekend with light breezes each afternoon through Monday. * A few showers or isolated thunderstorms are possible Monday and Wednesday afternoons with increased breezes around midweek. * Hotter conditions are expected late this week with triple digit heat possible in western Nevada valleys by next weekend. && .DISCUSSION... Hot and dry weather is in store this weekend with light breezes each afternoon. Plan on regional highs in the upper 70s and 80s today for populated areas of the Sierra and western Nevada. A warming trend promotes a return to 80 and 90 degree heat for Sunday, so make sure you practice your heat safety precautions. Mostly clear skies today become partly cloudy on Sunday as cumulus build-ups develop in the daytime. Some isolated showers may mature in the mountains of Alpine and Mono counties, but chances are only 10-15%. Given this, keep your eyes on the skies if recreating in the mountains Sunday! Pacific low pressure, albeit rather weak, will be nearly stationary as it meanders off the CA coast early this week. This low may provide enough instability for showers and isolated storms Monday afternoon in the Sierra and near the Oregon border (15% chance). The weak low will finally dislodge and advance across the region late Tuesday through Thursday. As it does so, winds may become breezy around midweek and yield elevated to locally critical fire weather conditions for portions of western Nevada. Shower and thunderstorms chances also increase Wednesday afternoon -- mainly for areas north of the I-80 corridor -- as the low passes overhead. High pressure amplifies towards the end of the week, allowing for widespread warming that brings highs closer to 90F and 100F for Sierra and western Nevada communities, respectively. -Salas && .AVIATION...
