Area Forecast Discussion National Weather Service Reno NV 158 PM PDT Fri Jun 21 2024

SYNOPSIS

* Trending warmer into the weekend with enhanced afternoon breezes and widespread dry conditions.

* Temperatures will be nearing 100 degrees in hotter valleys this weekend. Plan on widespread Moderate HeatRisk over the weekend.

* Slightly cooler temperatures along with typical west-southwest breezes will arrive for the latter half of next week.

DISCUSSION

* The weak upper low that had continued our comfortable temperatures has exited the region. High pressure will once again build across the southwestern US with a broad upper low over the PacNW. This pattern will allow for dry weather, increasing temperatures, and enhanced afternoon breezes through the weekend. Breezy conditions coupled with RH values in the single digits to low teens will lead to enhanced fire weather concerns for portions of western NV and eastern Lassen County this weekend, especially Sunday.

* It will be a hot one this weekend! Temperatures under the building ridge will near the century mark for much of western NV, eastern Lassen County, and the lower elevations of Mono County. The Sierra communities will be pushing into the mid to upper 80s, and even a few isolated low-90s. For Saturday, Reno Airport has a 75% chance of tying the record high (which is 100F), and a 55% chance of breaking that record. The last time we reached 100F or greater at the Reno Airport was July 23rd of last year. However, this would be early for the first 100F day of the year, which is normally July 14th.

* As a result of the incoming heat, we anticipate a Moderate HeatRisk may cause concerns for vulnerable populations. Look out for heat illnesses, stay hydrated, wear sunscreen and take care of those who may need assistance with cooling down. The good news of these temperatures is the cool overnight lows, which will help lessen the impacts of the afternoon heat.

* For Monday into Tuesday, we'll continue to be sandwiched between the high pressure centered to the southeast and the broad upper low centered to our northwest. This setup will slightly cool temperatures around 2-4 degrees. But, we'll remain above average for late June. By Wednesday and Thursday, ensembles show the high pressure over the western US breaking down while the aforementioned upper low moves through the PacNW. This will decrease temperatures back to average (which is 90F by the 28th), enhance afternoon winds, and continue our very dry conditions. With those ingredients in place, enhanced fire danger is an issue by the middle of next week. -McKellar

AVIATION

* Heat building in over the region may cause some density altitude flying issues. Lower valley terminals will hover near 100 for Saturday and Sunday. Sierra terminals will see upper 80s this weekend for daytime highs.

* Otherwise, we'll have VFR conditions, light winds, and typical afternoon breezes. -McKellar/HRICH
