Area Forecast Discussion National Weather Service Reno NV 202 AM PDT Fri Apr 19 2024

SYNOPSIS
Above average highs in the 60s for Sierra communities and 70s for lower valleys today. A few valleys may see highs surpass 80 degrees this weekend into Monday. Isolated shower chances near the Sierra this afternoon, otherwise dry weather remains through the weekend. Increased shower chances return next week.

DISCUSSION

Above average temperatures will be with us through early next week, increasing snowmelt on slopes and stream flows on area rivers and streams. See the Hydrology section below for more details on the warm weather affecting area waterways. Just how warm will we be? We expect the Reno International Airport to see their first shot at temperatures above 80 degrees this weekend. Western Nevada valleys will see high 70s to low 80s this weekend, while Sierra valleys will see upper 60s to low 70s for daytime high temperatures.

These warmer days may have you seeking outdoor recreation, however there is a chance (15-20%) to see an isolated thundershower for Alpine and Mono counties this afternoon. Also a slight chance (5-10%) of terrain driven showers near the Tahoe Basin today as well, so keep your eyes to the skies if you are outside.

Morning clouds on Saturday will clear out and leave us with clearing skies through the day, a great day to get outside and enjoy. Be sure to wear sunscreen this weekend, as abundant sunshine will be with us. Sunday we will see some clouds to the north, but another stellar sunny day to enjoy is setting up.

This good weather train will keep rolling into early week before we look ahead to more unsettled weather for midweek. A series of troughs will approach the West Coast, reintroducing showers to our forecast. Ensembles have yet to agree on the track and timing of these low pressure circulations, which will determine where the precipitation will land and how our temperatures will be impacted.
For now, we have 20-30% chances for showers across the Sierra and western Nevada.

Looking beyond, our extended outlooks are signaling a wetter pattern returning. Less clear will be how our temperatures shake out for the end of April and beginning of May. HRICH

AVIATION

* VFR conditions will prevail this weekend, although KTRK could see some patchy FZFG Saturday and Sunday mornings. Winds will be light with the exception of Saturday afternoon. Gusts of 20-25 kts will reach western Nevada valley terminals, while Sierra valley terminals may see gusts 15-20 kts.

* Showers and storms are anticipated along the Sierra from the Tahoe Basin to the south into Mono County. Chances for showers are 20-25% with the greatest threat for KMMH. Showers have a 10-15% chance of containing lightning.HRICH

HYDROLOGY

Above normal temperatures combined with mostly sunny skies will increase snowmelt leading to minor to moderate rises in rivers and creeks draining largely snow covered watersheds. While no flooding is expected in the area, many waterways will be running cold and fast, with gradually increasing flows into early next week. The West Fork of the Carson near Woodfords is expected to rise above the action stage each night through Tuesday, but remain below flood stage.

Rivers and streams draining mostly snow covered terrain below about 7500 feet are likely to see their seasonal peaks by early next week. Basins with significant higher elevation terrain will retain plenty of snow for higher flows with subsequent warmups.The Lower Humboldt is expected to have very high flows for many weeks with minor flooding likely in May or June, or even into early July.

Exercise caution around rivers and streams, remember mountain rivers and streams often reach their highest levels from snowmelt at night.
