High pressure will build in from the north this weekend with drier and warmer conditions expected. Highs will warm into the lower 70s across western Nevada valleys by Saturday afternoon, but highs will cool back down to near average by Easter Sunday as a cold front sweeps through the region. Temperatures look to warm again next week as high pressure returns.
Most residual shower activity associated with a cutoff low that has been meandering across the region since last weekend has dissipated this morning. Decreasing winds and clouds have allowed some localized areas of fog and low clouds to develop across western Nevada valleys this morning including Fallon and Lovelock with visibility around 1/4 mile being reported.
For today, the upper low will finally eject eastward as it gets picked up by a shortwave trough across the Pacific Northwest. This will allow upper level ridging to build as we head into the weekend with warming temperatures and drier conditions developing.
The ridge will build from north to south today with high temperatures near 70 possible across lower valleys of Lassen County and into the Surprise valley. Farther south, highs should reach into the mid-60s across western Nevada with 50s and upper 40s across northern and southern Sierra valleys respectively. Saturday will be the warmest day this weekend with highs about 10 degrees above average with lower 70s expected across western Nevada and upper 50s/low 60s across Sierra valleys.
An approaching back door cold front dropping in from the north will strengthen north winds by Saturday afternoon with some choppy conditions possible on Pyramid Lake. Behind the front, temperatures will cool back down to near season averages by Easter Sunday. There is a slight chance for a few mountain snow showers as well but no signals this would be anything significant. Fuentes
LONG TERM. Sunday through next week .
An elongated high pressure is forecast to build into the eastern Pacific next week. Lingering northerly flow behind this weekend's cold front will keep temperatures from rising too rapidly. Temperatures will start the week right around average, with mid 60s in the valleys and mid 50s in the Sierra. By the end of the week we'll likely see low to mid 70s in western Nevada with mid 60s in the Sierra.
Mostly dry conditions are expected throughout the week, but by the end of the week and into next weekend, the possibilities begin to increase that a cutoff area of low pressure moves into the region bringing more spring showers. -Zach
Low pressure spinning through southern California will keep a few remnant stratus around the Sierra this morning with possible mountain obscuration along with some ground fog at KTRK. Otherwise, clearing and VFR flying conditions can be expected today.
A mostly dry cold front is expected to move into Nevada from the north. This will create breezy surface winds in the west-central Nevada along with increasing clouds and a possible stray shower. -Zach

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
