::: Cooler with gusty winds, and a few clouds (high-elevation snow north of Tahoe) today and Thursday/ Warmer and mostly sunny, but cooler than average, Friday through Sunday (next week looks interesting) :::

DETAILED SUMMARY for the week -> Updated for Wednesday, May 22... Today and Thursday - An unseasonably cold (and strong) low pressure system sits across the northwest US, mainly WA and OR. This low looks will sit for a while, providing unseasonably cold air and some lower mountain snows to the Cascades, while we expect cooling and windy conditions across the northern Sierra. Showers and high elevation snow remain north of Tahoe.

Friday through Sunday - In general, low pressure hangs out across the northwest US and northern Sierra-Tahoe. We expect some clouds (but mostly sun), breezy to windy conditions, and cooler than average temperatures.CM

-28 May to 02 June, 2013 - Upper level low pressure holds on across the northwest US, with some clouds (but mostly sun), some late day west breezes, and near to cooler than average temperatures (this continues). Next week looks interesting for Tahoe and Mammoth, becoming much colder than average, with high temperatures remaining in the 40\'s (by next Tuesday or Wednesday), and potential snow down to 7,000 feet or lower. This is due to an unseasonably strong low pressure vortex, taking aim on the west coast and northwest US again. This one may be colder than the current low pressure center, that is dropping snow to 3,500 and 4,000 feet in some northwest US mountain areas (WA/ OR/ ID). CM
