502 FXUS65 KREV 101924 AFDREV Area Forecast Discussion National Weather Service Reno NV 1224 PM PDT Thu Apr 10 2025 .KEY MESSAGES... * High temperatures today and Friday reach the lower 80s across some western NV valleys but will fall short of record levels. * The next weather system moves in late Friday into Saturday with a return of breezy winds and cooler temperatures for the weekend. * Warm and dry conditions will return next week as high pressure sets up over the western US. && .DISCUSSION... * Warm late spring-like conditions will continue into Friday. Temperatures will be around 15-20 degrees above average for mid- April. Although very warm, the chance of seeing any record highs remains low. Since we`re experiencing the first major warmup of the year, minor heat risks are possible for those sensitive to heat. We`ll see the return of the zephyr-like breezes this afternoon and again for Friday. * Model ensembles still agree on a trough passing through the region late Friday into Saturday. This will first lead to gusty winds, especially along the ridges in the Sierra as well as into the inner basin and ranges. It will be breezy enough to be aware of choppy waters and possible adverse boating conditions for Lake Tahoe and Pyramid Lake on Saturday. This quick moving short-wave will be mostly dry for the majority of the area, with just a 15-25% chance for showers in northwest Lassen County and far northern Washoe County. Finally, temperatures will decrease in temperatures on Saturday and Sunday. But, readings will still be upwards of 5 degrees above average. * Large scale ridge returns next week. This will allow for temperatures to once again increase well above average with overall light winds. There are a few ensembles that want to introduce a cutoff low over southern California by Monday into Tuesday, which may introduce light showers for the Sierra. There is low confidence in this feature. Otherwise, we are mostly dry the next 7 days. -McKellar && .AVIATION... * Afternoon westerly breezes this afternoon with gusts up to 20 kt across all terminals. Wind gusts increase to around 25-30 kt Friday and Saturday due to a weak weather system passing through the area. This system may also introduce mountain wave turbulence and LLWS late Friday into early Saturday. * Well above normal high temperatures today and Friday for W NV valleys, bringing abnormally high density altitudes for early April. -McKellar && .REV Watches/Warnings/Advisories...
