Sat thru Monday - Quiet weather will persist as an amplified ridge of high pressure sits over the Sierra and western NV. Overnight lows will continue to be cold, dipping into the teens and lower 20s, with single digits for colder valleys near the Sierra. Highs mainly in the upper 40s and lower 50s. Relatively warmer temperatures with less diurnal fluctuations can be expected along the mid and upper slopes of the Sierra. Light easterly winds will continue for the next few days, due to the low level pressure gradient extending from the surface high across the northern Great Basin.
Tuesday onward...
Little change is expected in the overall weather pattern through next Thursday as high pressure remains in control of the region. Inversions will keep afternoon temperatures near average for the lower valleys, with the Sierra around 5-8 degrees above average. Nights will remain cold (a bit below average) with the dry air mass, light winds and little to no cloud cover. Generally light winds through the middle of the week. A weak upper disturbance is forecasted to drop south across the Rockies nudging the ridge axis back toward southern Oregon and the northern CA coast with possible moderate east ridge winds.
