Area Forecast Discussion National Weather Service Elko NV 202 PM PST Sun Mar 7 2021

SYNOPSIS. Fair conditions with mild temperatures will continue for Sunday. Monday will see an active pattern return to NV as a Pacific system impacts western CONUS for the next few days. Monday will see increasing cloud cover, gusty winds, cooling temperatures and isolated showers. Tuesday to Thursday will continue the trend of isolated showers and cloudy skies along with the cooler temperatures. Drier conditions then look to return to NV late in the week.

SHORT TERM. Today through Wednesday.

Today will continue with the dry and fair weather along with mild temperatures. Overnight lows will be in the upper 20s into the 30s for most areas.

Unsettled weather will return to the silver state starting on Monday as a Pacific system impacts western CONUS for the next several days. This will see a low pressure center move southward just off the west coast Monday to Wednesday. This trajectory looks to keep a majority of this system's moisture out of the silver state for Monday and Tuesday. The first feature of this system to impact NV will be a small portion of jet energy that separates from the main system and produces a small wave on Monday. This wave will from a weak cold front that will translate over NV on Monday and Tuesday. Wednesday will see the main system begin to impact NV as it begins to lazily move onshore.

Monday will see the split off wave system produce gusty winds across the region that will result in blowing dust across NV. This dust will reduced visibilities possibly even heavily so in localized areas near dust sources. This small split off wave will not take much moisture from the main system so showers are looking to be on the isolated side and lighter for Monday. The warmer conditions ahead of the front will allow for the showers to be rain to rain/snow mix early Monday before transitioning to all snowfall by Monday evening. The heaviest area of precipitation looks to be mainly in White Pine county on Tuesday when the cold front ends up stalling thus allowing more time for precipitation accumulation. Even then the precipitation amounts will remain on the light side and has trended downward so there is less confidence in any meaningful impacts. Winds will also be lighter on Tuesday as the gradient weakens. Temperatures will drop with the passage of this system with highs in the 50s for Monday and in the 40s for Tuesday. Overnight lows will do the same with lows dropping back into the 20s for Tuesday morning except for those pesky cold spots where teens will reign.

Wednesday will see the main system begin to impact NV as it moves to just off the coast of California. This will spread moisture from south to north into mainly southern and central NV with a little bit reaching as far as northern NV. This moisture will interact with the previous cold front boundary and cause showers across central NV. Alas the moisture will not be high so the showers will once again be on the lighter side. While some isolated showers could occur in northern NV they sadly wont be able to produce much if any precipitaton. Temperatures are expected to remain cool with highs being in the 40s for Wednesday.

LONG TERM. Wednesday night through next Sunday. Long term pattern favors a closed low circulation over the southwestern CONUS, but departing this region by Saturday. This system lacks deep moisture given the relatively low precipitable water content. Unsettled weather with some snow showers can be expected over central Nevada, but accumulations are expected to be on the light side. Do not see any ensemble solution that show any significant snowfall. The best accumulations may be limited to the Snake and Schell Creek ranges as easterly flow is possible Wed night and Thursday morning. Temperatures will be cooler with daytime highs around 10 degrees below normal Thursday, but slow recovery thereafter.

For next Sunday, the deterministic GFS shows a prominent weather system busting across Nevada as an open trough. High uncertainty for this occurrence, the next upstream trough could become another closed low circulation somewhere along the California coast. This lack of confidence is reflected in the PoP values that range 10-20% across northern Elko County and the Ruby Mountains with lower values elsewhere.

AVIATION. Some cirrus stream across NV tonight, but visibility stays good with no ceilings. Winds increase after 19Z Monday with gusts exceeding 25 kts, especially at KWMC and KELY.

LKN WATCHES/WARNINGS/ADVISORIES. None.
