101 FXUS65 KREV 070902 AFDREV Area Forecast Discussion National Weather Service Reno NV 202 AM PDT Sun Jul 7 2024 .SYNOPSIS... * Prolonged heatwave continues through nearly all of next week, with seasonable breezes and low humidity. * Low end chances for showers begin today, which become more likely late in the week. && .DISCUSSION... No major changes to the forecast since the last update. We`re still under an impressively deep and expansive ridge that won`t budge for the next several days. Reno Airport`s 100+ degree streak continued yesterday, with KRNO getting up to 105. That`ll be the third day in a row, as we expect 6-7 more 100+ degree days, including today. See our Climate section of the AFD for more info! Heat aside, our summertime zephyr breeze will be back each afternoon through the middle of this week, kicking up winds out of the west at 15-20 mph. Starting this afternoon and lasting through this week, hi-res models are picking up on a few light showers in southern Mono county along the Sierra crest. Shower/thunderstorm chances look to increase starting as early as Friday. Looking further ahead, we may finally see some relatively "cooler" temperatures coming next weekend! The high pressure system that`s currently overhead is looking like it will finally push off to the east to allow at least one, if not two, troughs to pass by. Long range ensembles are hinting at increased winds and increased PoPs this weekend, so stay tuned this week to get a more detailed forecast for this upcoming weekend! -Justin && .AVIATION... VFR conditions continue today and tomorrow. Expect routine westerly winds and gusts up to 20 kts. Pockets of wildfire haze possible between TVL-MMH, but likely no appreciable visibility restrictions. Hot temperatures could result in density altitude concerns for some aircraft each afternoon into next week. -Justin && .CLIMATE...
