A weak weather system passed through Northern California on Monday, bringing clouds and a few light sprinkles or snow flurries to areas of the north state. Magalia remained dry on Monday, with a high temperature of 44° and a morning low of 32°. There was only a 3 mph wind gust, with much of the day seeing calm winds.
Clouds which are proceeding Thursday's storm are spreading inland from the eastern Pacific this morning. The frontal band associated with the storm is predicted to stall off the coast of northwestern California tonight and Wednesday, but there may still be some light precipitation over the far northern areas of the state. Temperatures are running about 2° to 4° warmer this morning compared to 24 hours ago. The low so far has been 36°, with about 35° being normal for this time of year. Winds overnight have been almost nonexistent.
Today should see a mix of clouds and sun in Magalia, becoming mostly cloudy tonight. With these clouds will be a slight 10% chance of measurable precipitation by late this afternoon into the evening, increasing to a 15% chance by late tonight into early Wednesday morning. A warmer air mass is expected to spread over the region today as the weather systems on our doorstep are coming out of a more Central Pacific trajectory. This should allow for milder temperatures. The high temperature this afternoon is predicted to reach about 50°, but will be somewhat dependant on the amount of cloud cover we experience. The low tonight is forecast at 40°. We haven't seen low temperatures in the 40°s since a week ago Monday. It's been a cold 9 days. Winds today are expected to be out of a southwesterly direction at 2-5 mph. The snow level should be in the 5000' to 6000' range today and tonight.
Wednesday looks to be mostly cloudy with a 15% to 20% chance of precipitation throughout the day as clouds continue over the region. Most of the precipitation is expected to remain to the north of us on Wednesday. The afternoon high temperature is predicted to reach about 52°, and the low Wednesday night near 44°. Winds are expected to be out of the southeast at 2 mph to 6 mph on Wednesday. Snow levels are expected to be in the 6000' to 7000' range.
Thursday is expected to by cloudy with increasing chances of rain and wind in Magalia. A strong Pacific storm is expected to come ashore and bring heavy rain at times along with very strong winds. This mix many times brings Magalia downed trees or branches, and possible power outages and property damage. Precipitation odds are forecast at a 15% chance by early Thursday morning, but will increase to a 90% chance by late afternoon into the night. This should be a warmer storm than we've been seeing the last couple of weeks. Snow levels are expected to be in the 4000' to 5000' range on Thursday. Winds will increase out of the southeast as the day progresses, running 6 mph to 17 mph, and gusts reaching up to 24 mph during the afternoon into the early evening hours. Travel into the mountains may be very treacherous as heavy snow and strong winds could create whiteout conditions and dangerous conditions. Please keep up to date with the latest weather and road conditions if you need to head into the mountains.
Friday looks as though the rain and wind will be winding down during the morning hours, becoming partly sunny as a weak ridge of high pressure builds into the region. There should be some lingering rain showers in Magalia during the morning, but will quickly progress to the east. Saturday should see fair skies early, but increasing clouds late Saturday should bring the next shot at rain by Sunday morning and continuing possibly into at least early Tuesday. Snow levels should remain above 5000' through the period. The bottom image is the latest looking west from Chico towards the coastal range. Have a great Tuesday. Bob
