Area Forecast Discussion National Weather Service Reno NV 1258 PM PDT Sat May 4 2024
SYNOPSIS
A strong spring storm system brings gusty to strong winds, valley rain, and mountain snow with conditions gradually improving Sunday. For next week, look for a slow warming trend with lower precipitation chances continuing through the remainder of the forecast period.
DISCUSSION
RIGHT NOW: Current Satellite Imagery (1800Z) shows a classic comma shaped frontal band more indicative of a late winter season storm seen in February. This is the beginning of May isn't it! This is suppose to be the time for winter to be a recent addition to our long term memory receptors with warmer temperatures and flowers newly pushing out of the soil. I suppose you can also say the March lion jumped into May to remind us that Spring in the Sierra and the Great Basin is full of surprises. Indeed!
(Tonight through Monday)
* PRECIPITATION: The leading edge of precipitation is just now pushing into the Sierra with Donner Pass seeing rain making a change over to mostly snow. Snowfall rates across the central and eastern Sierra will quickly increase during the afternoon with Hi-Res ensemble guidance projecting a 1-2" per hour rate continuing for a few hours, then quickly tapering off early this evening to less than an inch before ceasing altogether later tonight into the early morning hours Sunday. HRRR guidance even projects a 40-50% chance for brief spurts of 3" per hour snowfall rates over more terrain favored areas of the High Sierra. Lingering bands of light to moderate snow showers will continue to bring an additional inch or two of accumulated snow on mountain passes before daybreak Sunday morning. As the upper low pressure opens and pushes east of the region through Sunday, precipitation will become more showery across western NV before diminishing later in the afternoon. For more details on snow amounts, please visit Weather.gov/rev/winter.
* WIND: Current Hi-Res HRRR guidance still indicates that the stronger south-southwest winds across the region will begin to diminish shortly after 6-8PM this evening. Until then, travel disruptions due to stronger cross winds will continue to make travel tricky across western NV roadways, especially for those wind prone areas along US-395 from the greater Reno area all the way south into Mono County. This includes US-95 through the Hawthorne area where there will still be that 70% chance for some gusts exceeding 50-60 mph. All area lakes will also experience strong winds creating choppy, unsafe conditions going into the early evening hours. A breezy northerly flow will spread over the region overnight that continues through Sunday.
* TEMPERATURES: With daytime highs for Sunday dropping as much as 15- 20 degrees below seasonal average for this time of year, it will feel more like a normal early February day! Of greater concern with the cold temperatures will be the overnight lows for Sunday and Monday mornings. Freezing temperatures of at least 32 degrees are looking likely (>60%) for most of western NV on Sunday morning. Lows for all Sierra communities will drop down into the upper teens to low 20s. If you haven't already done so, it is recommended to protect vegetation that is sensitive to these colder temperatures. Even with a 15-20% chance for a “Hard Freeze” under clearing skies overnight Sunday into Monday morning, agricultural interests in some lower valley areas of the Basin and Range may need to mitigate the results of the unseasonably colder Monday morning low temperatures.
(Tuesday-Friday)
* OUTLOOK: Blended guidance continues to project a gradual warming trend through next week with drier conditions continuing as well. Cluster ensemble guidance looks to place a positive tilted long-wave trough pattern that extends from the southern Great Basin northeast across the central Rockies. It's placement of a amplifying area of high pressure across the northeast Pacific into western Canada as well sets up a REX blocking pattern over the western US. How the easterly flow aloft sets up over western NV into the Sierra will determine how much our upcoming warming trend actually warms. One thing for sure, the longer play is for drier conditions to continue. Also look for a brief return of breezy easterly winds across higher Sierra ridges overnight Wednesday into Thursday morning. Has Spring finally sprung! Let's see what pans out going into the upcoming week.
AVIATION
A strong, unseasonably colder spring storm system continues to advance into the region through early Sunday morning.
* Snow/Rain: Widespread mountain snow showers and valley rains are likely (>70%) through tonight in northeast CA, the Sierra, and western NV. Snow levels are projected to fall to 5000-5500 feet into the evening. Sierra terminals KTRK, KTVL, and KMMH could still see between 1-3" of snowfall with a 40-60% chance for at least 2". Look for mostly MVFR (40-60% chance) airfield conditions with brief periods of IFR (15-20% chance) conditions in moderate snowfall into the evening hours. Higher sun angles in May, however, may still limit accumulations on runways at those terminal during until the evening hours. There is also a slight chance for snow flurries tonight into early Sunday morning for far western NV terminals (KRTS-KRNO-KCXP-KMEV).
* Winds: Stronger southwest winds will diminish this evening across the Sierra and western NV into the evening with breezy northwest winds through Sunday. Look for sustained ridgetop winds across the Sierra of 30-40kts with gusts topping 70kts this evening. Expect periods of mountain wave turbulence, as well as LLWS for all area terminals into the evening as well.
Gusty to strong west to southwest winds are possible for all western NV and Sierra terminals through tonight.
* Look for generally VFR airfield conditions for main terminals and lighter west-northwest winds. The only exception will be areas around the Martis Valley to include KTRK with the increased chance (15-20%) for patchy dense freezing fog forming during the early morning hours Monday and Tuesday that quickly "burns off" shortly after day-break. - Amanda
