Strong winds and significant precipitation continued across Northern California and the Northwest on Sunday as a strong Pacific frontal system pushed inland through the West.

A warm moisture plume from the Pacific accompanied this energetic storm and allowed for widespread showers, heavy rains, and high elevation snow to develop across the already well saturated areas of the Pacific Northwest and Northern California.

As of this afternoon, 24-hour rainfall totals in Northern California have ranged from about 4 to 6 inches, with locally higher amounts. Significant rainfall during the last several days led to some minor to moderate river, stream, and road flooding as well as mudslides in select areas.

The brunt of precipitation associated with this system shifted into the Intermountain West and central California through the afternoon as the system reached from the Northern Rockies to the Bay Area. Snow totals of 5 to 9 inches were expected in the Sierras above 6,000 feet and 6 to 11 inches above 5,000 feet in the Intermountain West and Northern Rockies.

In addition to precipitation, strong winds of 30 to 40 mph with gusts exceeding 60 mph were reported with the passing of this storm. Strong, damaging gusts led to numerous downed trees, blowing debris, and left thousands without power in parts of Northern California.

Meanwhile in the East, a low pressure system moved eastward through the Great Lakes and pushed a cold front eastward across the Eastern Valleys. Periods of heavy rain showers developed ahead of this system and reached into the Northeast by the afternoon.

SUNDAY'S WEATHER EXTREMES:

HIGHEST TEMPERATURE (DEGREES F).........................87 Alice, Texas

HIGHEST HEAT INDEX (DEGREES F)..........................86 Alice, Texas

ON THIS DATE....... Have you ever seen a meteor so bright it lit up the night sky? Apparently on this date in 1874, residents of Shreveport, La., saw a meteor that was described as being "brilliant, exploding with blue and yellow light."
