Northern California weather is changing.........
National Weather Service
Statement as of 3:42 PM PDT on September 30, 2011
... Cooler... wet and windy weather next week...
A series of cold fronts will sweep across northern California
next week. Temperatures will begin to cool this weekend ahead of
the first front... due to arrive Monday. Rain showers will spread
across the region Monday and Monday night. Snow levels may briefly
drop to around 8500 feet including higher passes such as Sonora
pass and the Highway 89 Summit Area near Mt. Lassen by Monday
night. Only a light dusting of snow is expected initially.
A stronger cold front may spread periods of moderate to heavy rain
across the valleys and foothills Tuesday night and Wednesday.
Gusty southerly winds may accompany this front. Temperatures will
drop to 10 to 20 degrees below normal with highs only in the 60s
in the valley and 40s in the mountains on Wednesday. Snow levels
may drop to around 5500 feet late Wednesday into Thursday. This
will bring snow to the trans-Sierra passes Wednesday into Thursday.
While the exact timing and details of this weather system are
still coming into focus... be aware that winter traveling
conditions are expected over all trans-Sierra passes Wednesday into
Thursday.
Motorists should be alert for slick roads due to the first rain
of the season along with accumulated oil on the roadways. In
addition... be prepared for winter-like weather across the Sierra.
Residents should also be prepared for other impacts of the windy
wet weather. Gusty winds could lead to fallen leaves clogging up storm
drains causing localized street flooding. There could also be power
outages should branches or small trees fall and damage power
lines. Small stream and urban flooding may also occur during
periods of moderate to heavy rain which could impact Road travel.
A showery and unstable air mass may remain over the region
into Thursday. Continue to monitor National Weather Service
forecasts and statements for updates on this developing unsettled
weather.
