491 FXUS65 KREV 130747 AFDREV Area Forecast Discussion National Weather Service Reno NV 1247 AM PDT Sun Jul 13 2025 .KEY MESSAGES... * Dangerous heat will continues through Tuesday, with widespread Moderate to Major HeatRisk across lower areas of western Nevada and northeast California. * Plan on a low possibility (5-10% chance) for isolated, high- based thunderstorms through the weekend, with increasing chances Monday and Tuesday. * Hot, dry conditions will marginally subside mid-late next week with increasing southwest to west winds. && .DISCUSSION... Summer is in full swing! The Reno Intl Airport hit 101 degrees yesterday; our first 100+ degree day of the year. For those that enjoy the heat, great news! We`re going to be even warmer today. Locations across W NV, including the Reno-Carson-Minden area, will see highs in the triple digits today and tomorrow while our friends in Sierra communities will be in the low to mid 90s. Unfortunately, with relatively high overnight lows, heat recovery isn`t ideal. Limit time outdoors during peak heating hours (10a-5p) and make sure to stay hydrated. As fires continue to rage in N CA and S OR, smoke infiltration will continue to impact much of the area, bringing hazy skies. Due to strong surface heating this weekend, though, this brings an increase in instability. This will allow for a 5-10% chance of isolated showers and thunderstorms, primarily along the Sierra each afternoon. As a low pressure system drops down from Canada by the middle of next week, shower chances increase Tuesday through Thursday. That low pressure will also help bring afternoon high temperatures down to near-normal. We cool down starting Tuesday but this will be relatively short-lived as another high pressure system starts to build towards next weekend. -Giralte && .AVIATION... VFR conditions prevail through the weekend along with light winds and typical afternoon W-SW wind gusts up to 20 kts. Expect a 5-10% chance of isolated thunderstorms each day between 21-03Z, primarily for Sierra terminals. Primary storm concerns will be brief outflow gusts and localized turbulence. The hot temperatures may produce density altitude concerns, especially for KTRK, KTVL, and KMMH. Slantwise visibility reductions remain possible with haze from wildfires in northern California and southern Oregon. -Giralte/Edan && .REV Watches/Warnings/Advisories...
