Area Forecast Discussion National Weather Service Elko NV 310 AM PDT Fri Oct 22 2021 .SYNOPSIS...A first in a series of moist and windy Pacific waves moves across northwestern and far northern Nevada today. Showers will expand across northern Nevada region on Saturday with cooler temperatures. A much stronger Pacific storm brings widespread rain on Monday. && .SHORT TERM...Today through Saturday evening. The first in a series of Pacific waves with deep moisture is moving across northern California, projected to move into western Nevada later this morning. With the long wave trough remaining well offshore, the leading wave encounters the downstream ridge and lifts northeast into Idaho. Showers are expected along the front as it moves across Humboldt County, but becomes less organized as it slides across northern Elko County. This fast moving wave only generates light rainfall amounts with valley spots receiving less than a tenth of an inch /0.10/. Windy conditions are expected with gusts reaching 30-35 mph this afternoon. Upstream secondary wave will carve out a low amplitude trough over the Great Basin by Saturday morning, re-energizing the surface front over northeast Nevada. Showers will expand across northern Nevada as far south as route US50. The trend will be for diminishing showers Saturday as the secondary wave moves downstream. The highest rainfall totals occurs along the front and local spots in northeast Nevada could receive a quarter inch /0.25/. Snow accumulations limited above the mountain passes, although a rain/snow mix may occur above 7000 feet. .LONG TERM...Saturday night through next Thursday. Saturday evening through Tuesday, is shaping up to be a very wet period across the whole of NV. This will come in the form of a atmospheric river system and it supporting trough passing across western CONUS. This will spread rain and snow across NV starting in the northwest NV Saturday night. This precipitation then looks to reach its zenith Monday early morning to early afternoon. The precipitation then looks to dwindle downward through Tuesday and largely end by Wednesday. The precipitation should be mainly rain for the valleys as the system does not bring colder air across NV until Tuesday morning when the event is starting to end. Any snowfall that does occur will be in the highest mountains peaks which may pick up significant snowfall. The overall amount of moisture associated with this event has continued to increase from previous model runs. The ensembles have continued to favor higher moisture and precipitation amounts as the system comes closure to occurrence. These have pegged this system as being in the 99% 99.5% percentile across NV during it zenith on Monday morning. What this means in simple terms is this is shaping up to be an extreme event that can produce historic amounts of precipitation for the 25th of October. The current favored amounts of 0.5 to 1.0 inches of rain may not sound like much but these beat out the current records which stand at 0.25 to 0.4 inches of rain. Given that this rainfall is over a long period of time impacts are not expected to by high as of now. Through not as dramatic as the rainfall this system should produce gusty winds across northern and central NV during its passage with gusts generally in the 20s and 30s mph range. There could also be a few stronger gusts in the 40s mph in White Pine County as well with better chances at higher elevation. Wednesday through Friday, should see the system fully depart the region with the pattern favoring a shift to a ridge. The overall intensity of the ridge is hard to pin down but ensembles are favoring a stronger overall ridge. This should produce a fairly warm period across the silver state with fair weather and lighter winds. && .AVIATION... VFR conditions are expected through the next 24 hours, though -SHRA possible after 20Z at KWMC may bring degraded CIGS to 2.5K FT AGL. Strong winds are expected to develop across all TAF sites this afternoon SW-W10-20G30-35KT. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 88/86/86
