Area Forecast Discussion
National Weather Service Sacramento CA
155 PM PST Tue Jan 24 2017

Dry weather through the next week outside of a few showers
Thursday across northern portions of the state.


Weak high pressure will continue to build into the area through
Wednesday with dry weather and chilly overnight temperatures.
With light winds and clear skies, fog development possible in the
Valley toward daybreak tomorrow morning, mainly from Marysville
southward. A weak shortwave will drop SE on Thursday, but will
have little impact on the area. A few showers possible across
northern portions of the state, mainly across higher elevations,
but precipitation amounts won`t amount to much as wave is
moisture-starved. Otherwise, ridging builds back in for the rest
of the week with dry weather and a gradual warming trend in
temperatures. Valley fog possible from time to time in the morning



High amplitude upper ridge shifts inland over Interior NorCal
Saturday and persists into Monday. This will result in above
normal temperatures with some night and morning valley fog. Models
differ with timing of next Pacific frontal system with oper GFS
about 12 hours slower with onset of precipitation than ECMWF-
HiRes. Both suggest potential for more widespread precipitation by
the middle of next week.
