The National Weather Service anticipates a late fall storm on Thursday will deliver wet and windy conditions.

Wednesday’s weather is much like earlier in the week, although the morning was warmer than Monday and Tuesday. The high temperature on Wednesday is expected to reach 58 degrees in Sacramento.

The weather system forecast to arrive on Thursday is expected to be warmer and deliver less rainfall than previous storms. However, Sierra travel could still be hampered, according to the National Weather Service.

Nearly a foot of snowfall is possible at the higher elevations of the northern Sierra. Several inches of snow could fall to around the 4,500-feet elevation.

In the Sacramento Valley, a quarter- to a half-inch of rain is forecast. Winds will ramp up Thursday as the system moves through with sustained winds around 20 mph and gusts to 30 mph in Sacramento.

In timing the arrival of the rain, the NWS expects that showers will begin in the mid- to late-morning along the Coast Range. In the late morning to the afternoon, interior California, including Sacramento, will see rainfall as the system moves quickly over the north state, according to forecasters.

The heaviest snowfall in the Sierra will occur in the afternoon and through the night. Skies clear on Friday.
