Sunday was about as nice of a day in Magalia as you will find at anytime of the year. Clear and sunny skies, along with an afternoon temperature of 74°. The low Sunday morning only dropped to 55°. The ridge of high pressure shifted over Northern California and brought us the beautiful weather. Winds were generally light on Sunday, with only a 5 mph gust.
This morning is seeing some high clouds begin to filter into the area as an upper low pressure area off of Baja California slides northward towards Southern California. There are some radar echoes associated with the clouds over Southern California, and even a few light rain showers over far southern areas of the state, but no heavy accumulations. Most locations are reporting about 0.01" of accumulated rainfall, and are down towards the Salton Sea and Coachella Valley areas.
The ridge of high pressure which brought us the warm temperatures on Sunday is shifting to the east of us. This is allowing for some cooling this morning, as temperatures are running 10° to 11° cooler than the same time on Sunday morning. The low temperature so far at this location this morning has been 46°. Winds overnight have been light and variable, with a peak gust of only 3 mph.
Today should see a mix of clouds and sun as high clouds begin to thicken and increase as the day progresses. By tonight, skies are predicted to be mostly cloudy. This is a rare weather pattern for this time of the year as we typically don't see subtropical weather systems drift this far north. No measurable precipitation is currently predicted to fall in Magalia today and most of tonight, with a 5% chance of precipitation by late tonight into early Tuesday morning. We will likely remain dry throughout today and tonight. The snow level tonight is expected to be near 7400'.
The high temperature this afternoon is expected to be cooler than Sunday as the ridge of high pressure will be to our east and allow for a cooler air mass to spread over the area, and some cloud cover will block out the sun at times. The high this afternoon is predicted to reach a cozy 65°, and the low tonight about 48°. The normal temperature range for this time of the year is 52°/32°. Winds this afternoon are expected to be generally out of the southeast at 2-5 mph. Those winds will be southeasterly, and up to about 6 mph tonight.
Tuesday may see the high clouds lower and thicken enough to allow for some precipitation to fall in Magalia by the early morning hours. By about sunrise, the odds that we will see 0.01" or more rainfall will rise to 35%, and increase to a 45% chance by about late morning into the early afternoon. Most of the precipitation is currently predicted to remain to our south over Central California. By late afternoon, rainfall odds drop back to about 20%, and continue to decrease to a 15% chance by late Tuesday night. Temperatures should also continue to cool on Tuesday as cloud cover and a cooler air mass drops the afternoon high to only about 55°. The low Tuesday night is expected to be near 45°. Winds should be southeasterly at 7-9 mph Tuesday afternoon, becoming light and variable Tuesday night.
Wednesday should see a continued decreasing chance for rainfall, and a warming trend. Thursday looks to be similar to Wednesday's weather, give or take a little in temperatures. Friday may see a slight chance of a shower as an upper trough of low pressure will be over the Desert Southwest. A return to fair and mild conditions are expected for this weekend, including Super Bowl Sunday. Have a great Monday. Bob
