Major Winter Storm Still on Track for The Area Tonight Through Thursday Night

The latest webcam image looking over the Eagle and Carson Valleys shows our next storm moving into the area with rain and high elevation snows already beginning to spill over into the Carson City area. Expect conditions to deteriorate tonight especially in the Sierra and Carson Range where a blizzard warning remains in effect until 7 AM Thursday. The latest satellite image continues to show a very well-developed area of low pressure approaching the west coast with several imbedded shortwaves moving into the longwave trough. This will bring a round of heavy precipitation to the area through Thursday night.

The latest HRRR radar composite simulation continues to show an intense NCFR (narrow cold-frontal rain band) developing over the Sacramento Valley by 06Z – 07Z. This NCFR will move into the Sierra tonight to intensify the blizzard conditions expected by 09Z (2 AM). Spillover into western NV looks good, with rainfall amounts of around .75 inches at KCXP and KRNO. These are typically the driest parts of the Reno/Carson City areas. Those living closer to the Carson Range can expect greater amounts of 1 to 1 1/2 inches of rain by Thursday afternoon. Rain may change to snow in these locations with some accumulations especially above 5,000 feet. Light rain showers are already beginning in the west Carson City area. Snowfall amounts continue to look impressive in the Sierra and Carson Range, with 3 – 6 feet above 7,000 feet and 1 – 3 feet between 6,000 and 7,000 feet by Thursday night.

Looking ahead, drier weather conditions will return to the area for Friday through Sunday ahead of the next cold front expected to move into the area. This storm system will be much weaker and will be a warmer storm to begin with. A cold front will bring snow levels once again to the valley floors for some possible accumulations.  Dry weather is expected to return for an extended period through at least the end of January.

More later as conditions change.
