DAYS 1-5 (DECEMBER 1-5)
A colder westerly flow dominates our weather during the next few days. Today, clouds will tend to increase from 3 sources: 1) South Coast region ocean-effect clouds. 2) Fair-weather cumulus that develop over land areas. 3) High to mid level clouds from a disturbance passing south of the area. Sunshine will be more dominant Monday and Tuesday across the region. Wednesday, clouds return from west to east ahead of an approaching “clipper” type low pressure area that traverses the Great Lakes region then moves north of our area. This system can produce a period of snow (rain or snow coast) later Wednesday with some minor snow accumulation possible where it snows long enough. A few snow showers can linger into Thursday as the system departs and a new surge of cold air arrives from Canada.
TODAY: Partly sunny. Highs 37-44. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Cloudy. A period of snow except rain or snow coast. Lows 30-37. Wind variable 5-15 MPH.
THURSDAY: Variably cloudy. Chance of a snow shower. Highs 35-42. Wind W to NW 10-20 MPH, higher gusts.
DAYS 6-10 (DECEMBER 6-10)
Cold but diminishing wind December 6 with dry weather expected as high pressure moves closer. A weak and fast-moving disturbance brings a chance of snow showers December 7. Dry weather follows this but a shift to a more southwesterly flow may allow low pressure with more substantial moisture to arrive by the end of the period with a precipitation threat.
DAYS 11-15 (DECEMBER 11-15)
Another low pressure area threatens some precipitation about mid period, otherwise mostly dry start and end of period with variable temperatures but no extremes indicates.
