KEY MESSAGES
1. Temperatures are expected to warm up again today and will rise back to above normal by this weekend.
2. There is a chance for showers across the Sierra Nevada today.
3. Locally breezy conditions expected across the Mojave Desert through this weekend.
DISCUSSION
Temperatures have been cooler the past few days due to a strong trough in the Great Basin. However, we can expect temperatures to warm up a tad today once the remaining stratus burns off.
There also is a 5 to 10 percent chance of afternoon showers and thunderstorms in the Sierra Nevada in the higher elevations today thanks to the trough.
However, the trough will slowly slide away and a ridge moves in from the Pacific coast bringing temperatures back up. Saturday has a 55 to 80 percent chance of high temperatures of at least 80 degrees in the Valley. Temperatures will increase on Sunday which will be good for those doing outdoor activities to celebrate Easter with a 30 to 75 percent chance of high temperatures of at least 85 degrees. Monday and Tuesday continues the warming trend, however, the ridge will be weakening. Tuesday has a 10 to 55 percent chance of high temperatures of at least 90 degrees.
However, a shortwave trough slides in on Wednesday bringing temperatures back down. Another trough is expected to move in on next Friday. This bigger trough currently has a 20 to 25 percent chance of any rain accumulation for the San Joaquin Valley.
However, the ensembles show uncertainty as one cluster of members has not picked up on the trough. The long term CPC Outlooks have equal chances of above and below temperatures but also a 33 to 40 percent chance of above average precipitation.
