Adios to our record warmth Sunday & Monday. Our abrupt changes started Thursday with conditions dropping into the 60's Inland. Right now we are tracking a low pressure system moving from the Pacific Northwest which has plenty of cold and unstable air. This will bring widely scattered rain for the weekend, possible t-storms, & low snow (3,000 feet).
Will this be our wettest storm so far this season? No
Will this be the coldest storm in recent memory? Yes
FRIDAY: Clouds Increase. Stays cold 50's Inland. Afternoon chances of scattered rain.
SATURDAY:Scattered Rain, Cold & 50's Inland, Isolated T-storms Possible, Heavy Sierra Snow & Wind.
SUNDAY:Scattered AM Rain, Cold & 50's Inland, Isolated T-Storms Possible, Heavy Sierra Snow Continues.
MONDAY: Chance of showers with gradual clearing and drying.
*This recent pattern from hot to cold in a matter of days is another example of weather extremes in a La Nina cycle. Also, Thanksgiving looks dry with low 60's Inland over the Bay Area.
