Light snow possible around Carson City by Christmas, travel impacts likely over Sierra
Winter weather will get to time for Christmas with an excellent potential for rain embracing light snow Monday night into Christmas morning around Carson City and valley areas and a good opportunity for snow accumulation in the Sierra, based on the National Weather Service.
A THE WINTER SEASON Advisory is in place from 10 a.m. Monday to 7 a.m. Tuesday for Lake Sierra and Tahoe. Total snow accumulations of just one 1 to 5 inches below 7,000 feet is expected with 6 to 15 inches above 7,000 winds and feet gusting as high as 60 mph over Sierra ridges. Through Monday morning the optimum time for holiday travel is currently, weather forecasters advise.
For the Sierra, snow levels shall start around 6,500-7,monday afternoon 000 feet, falling to below 5 rapidly, monday evening 500 feet behind a cold front. Travel could possibly be very difficult. The morning or evening commute the hazardous conditions could impact.
A THE WINTER SEASON Advisory for snow means periods of snow shall cause primarily travel difficulties. Expect snow covered roads and limited visibilities. The most recent road conditions are available at NVRoads.com or calling 511.
By Sierra standards, this is simply not a significant storm, with 6-15 inches likely for areas above 7,000 feet, however the increased holiday traffic will compound the impacts, in line with the weather service. The snow begins off as heavy and wet before transitioning to powdery and light.
NWS weather models attended into better agreement in the timing of the cold frontal passage, monday evening looking likely for NE CA and the northern Sierra with, between 8 p.m. and midnight for the higher Carson and Reno City metro areas in to the Central NV Basin and Range, and between 10 p.m. and 2 a.m. for Mono and Mineral counties.
Still, the largest boom or bust potential in the forecast is snow amounts in the 5,500 to 6,500 foot range, where totals could range between an inch or two around six inches. Your day Monday will boost high temperatures decent mixing during, and models have already been trending on snow levels for the daytime hours upward, forecasters say.
Snow levels fall behind the cold front quickly, however the relevant question may be the timing of the moisture with regards to snow levels falling. Several models are showing a burst of heavier precipitation rates with leading, which alone could drag snow levels faster down.
Most of the precipitation shall fall as rain across western Nevada, but light snow along and behind the cold front isn’t out from the relevant question. Minor accumulations are possible, especially given the snow will overnight fall, although weather services advises that it will not be much, likely an inch or less. Higher elevation sites including the Virginia City Highlands into Virginia City itself could see 1-2 inches of snow overnight into Christmas morning.
In addition to the rain and snow, your day Christmas Eve in to the night winds increase late in, with peak speeds reaching 35-45 mph in valley locations. For most, this is simply not as strong because the handful of wind events the certain area experienced earlier this week, but strong enough to blow down any unsecured holiday decorations still.
day with northerly winds rendering it feel even colder
Cold temperatures and lingering snow showers will persist through Christmas. The cold northerly flow over the warmer lake waters could produce lake enhanced snow showers downwind relatively, to southeast of Pyramid Lake south. Winds will be shifting from north to east over Lake Tahoe, therefore the deeper unidirectional flow necessary for lake enhancement is less inclined to create.
Forecasters say Thursday and Friday there could be increased cloud cover and added slight likelihood of snow showers across more portions of our region. Overall, NWS forecaster say expect a couple of days of brisk and chilly conditions between Christmas and New Year`s Eve.
