A very cold weather system arriving in California on Thursday will bring MUCH colder than normal early April temperatures and the potential for a good dose of late season rain for the North Bay region.

On Wednesday the storm and cold low pressure center was sliding south along the West Coast.

With origins near Alaska this storm will bring very cold air to California, as much as 25 degrees below average for early April. High temperatures will have a hard time reaching 55-60 degrees through Sunday. It will feel like winter has returned.

A cold, blustery rain will begin spreading across the North Bay in the early morning hours of Thursday, continuing in showers through the day and possibly into early Friday.

Forecast rainfall has trended upward, from a couple of tenths of an inch to more than a half of an inch on the European model forecast. We should expect a range of a quarter to a half inch of rain over the North Bay by Saturday.

The cold air moving into California will cause snow levels to plummet by Friday, as low as 2500 feet across the North Bay. We may see some light snow on the higher peaks of the Bay Area and coastal ranges, while more than a foot of snow is possible in the Central Sierra.

A weak disturbance may bring more showers on Sunday, with cold air in place. But beginning on Monday we will see a warm up back to mild spring temperatures in the 70s, a pattern that should last through Sunday the 14th, with high pressure in charge.

Although there are hints of disturbances returning around mid-month, no big storms are in the forecast and the models suggest the third week of April may bring seasonable warmth across California and much of the West. Stay tuned!
