Dry and warmer weather this coming week with breezy northerly
winds during the middle of the week as high pressure rebuilds
across the region.
Mostly clear skies across the region early this morning except for
some cloudiness across the far northern portion of the forecast
area associated with a fast moving weather system. Early morning
temperatures range from the upper 30s and 40s in the mountain
valleys to the mid 50s to lower 60s elsewhere, a little warmer
than 24 hours ago.
Similar conditions to Monday are expected across the interior of
NorCal. Another short-wave is forecast to clip the region this
evening bringing some more clouds to the northern mountains and
northern Sierra. Behind this wave, strong high pressure is
forecast to begin building into the region.
Tuesday night into Wednesday the northerly surface pressure
gradient increases over the region. Winds will become breezy to
locally windy across interior NorCal. High temperatures will warm
by several degrees for most locations into the mid 80s for the
valley and 60s to lower 70s for the mountains.
The winds will be lighter by Thursday and temperatures will
continue to warm to around 90 degrees in the valley as high
pressure builds further over the region.
Hot and dry pattern continues into early next week with high
temperatures well above normal.
VFR conditions next 24 hours except local mountain valley fog
over the Sierra through about 18z. Mainly northerly winds
increasing after 18z with sustained surface winds 10 to 29 knots
higher terrain and northerly Sacramento valley after 06z
