Area Forecast Discussion
National Weather Service Sacramento CA
330 PM PST Mon Dec 11 2017

Dry weather into early next week with mild days and chilly


Strong blocking pattern continues along the West Coast. As a
result, dry conditions will persist across interior NorCal with
mild days and chilly nights. Afternoon temperatures are running a
few degrees lower compared to 24 hours ago, with Valley locations
generally in the 60s.

Atmospheric pattern remains relatively unchanged as the ridge
remains anchored overhead and dry weather persists. Some patchy
morning frost or fog will be possible in the Central Valley.
Daytime highs are forecast to be several degrees above normal,
with an area of 30 yr return intervals at 850 mb that supports
possible record highs across portions of the northern Sacramento

A trough will be pushing into the PacNW to start the extended
period. This will push a cold front through NorCal with no precip
expected. The ridge will build back in for the weekend continuing
our streak of dry weather. High temperatures will remain mild
throughout the extended period running 6-12 degrees above normal
with near normal overnight lows.



VFR conditions expected over the next 24 hours at TAF sites.
Areas of HZ increase after sunset and local areas of MVFR/IFR at
the southern terminals between 12 and 16z Tuesday due to patchy
fog. Winds remain light under 10 knots. &&
