SYNOPSIS

Active weather continues this weekend for western NV, the Sierra and Northeast CA. The windy pattern continues this afternoon and evening then diminish overnight. Periods of rain and snow showers persist through Sunday. Drier conditions and seasonal to above normal temperatures prevail next week.

DISCUSSION

Upper low off the CA coast as seen in water vapor satellite imagery will be the main feature generating hazardous weather this weekend. Currently, winds are picking up in strength this afternoon due to a surface low in western NV. The tight pressure gradient leads to gusty winds generally from the south. Peak winds will continue through early evening with ongoing wind advisories through 8 PM from west central NV southward to Mono County. The gusty winds will generate blowing dust over parts of Pershing, Churchill, Lyon and Mineral counties. Winds shift to the west behind a cold front this evening, then diminish in the late evening and overnight hours.

The upper low keeps an easterly trajectory which means that we will continue to deal with its effects through Sunday night.
Therefore, periods of rain and snow associated with this system begin this afternoon in the Sierra and NE CA, then translate towards W NV. Snow levels start at 6-7 kft this afternoon, then drop to 5-5.5 kft this evening behind the front. By Sunday morning, snow levels will be in the valley floors. The good news is this system doesn't have as much moisture compared to previous ones this season. HRRR has much of the precipitation ending late in the morning with lingering light showers during the afternoon.
There is marginal instability too, so some pellets could be possible along with the rain and snow in the valleys. Snow accumulations will be generally light, especially for western NV. The highest snow accumulations will be over Lassen, Plumas and far northern Washoe county near the OR border with amounts between 3-6 inches and isolated up to 9-12 inches for the highest elevations. The probability for amounts exceeding 6 inches is 20-40% in Lassen County. For this reason, a Winter Weather Advisory remains in effect for northeast CA above 5000 ft from this evening through Sunday morning. Snowfall rates of 1-2 inches per hour are possible late this evening in northern Lassen County.
Otherwise, rates will be generally below 1 inch/hour. The warm temperatures over the last few days will hinder the ability for the snow to stick to the ground early on, so the actual accumulated snow especially on roads may be less than the amounts mentioned in the advisory.

The upper low weakens as it continues its eastward track into UT and CO. Meanwhile, an upper ridge develops to our west and slowly expands into the Great Basin. Subsequently, drier conditions and warmer temperatures are expected starting on Monday. Seasonal temperatures are expected early this week, which will reach above normal values by mid-week. There are some weak shortwaves embedded in the flow that could bring brief periods of showers, and maybe a lightning strike or two, especially on Thursday.

AVIATION

For Western NV terminals mostly VFR conditions. Periods of rain and a few storms will drop CIGS and VIS but mostly remain in the VFR category. However, the strongest activity could drop CIGS & VIS to MVFR. Some light snow is possible after 9Z, but accumulations will be very light if any at all. Mountain obscurations are likely due to the lower clouds this evening.

Sierra & NE CA terminals start with VFR conditions. However, conditions deteriorate through the afternoon resulting in MVFR due to periods of rain and snow reducing CIGS and VIS. Snow is possible after 00Z.

Gusty winds are expected areawide this afternoon-early evening.
Winds will be from the south between 10-25 kts with gusts up to 35 kts at terminals. Peak gusts up to 45 kts are possible from KLOL to KHTH. Winds shift to the west between 21-02Z as a cold front pushes through the area from west to east. Gusty winds will generate BLDU in western NV leading to reductions in VIS down to 1-3 SM into the early evening, along with mountain wave turbulence and localized LLWS.
