An unsettled weather pattern is expected for this weekend as a weather system is set to move through the region. This weather system will lead to increasing precipitation chances this weekend. Rain will develop across SE CA on Friday and slowly push eastward through the weekend. Better rain chances arrive Saturday-Sunday as the low pressure system moves through the region. The associated cold front (and best chances for heavy rainfall) will move through the region Saturday into Sunday, Saturday morning and afternoon across SE CA and SW AZ and Saturday night/Sunday morning across SC AZ and E AZ. Rain chances will then decrease by Sunday evening as the system exits the region to the east.
A weather system this weekend will bring increasing rain chances with locally heavy rainfall amounts possible. The heaviest amounts are expected across portions of Joshua Tree National Park where a Flood Watch has been issued for Saturday morning through Saturday night.
Temperatures will cool heading into the weekend, however they will remain above normal through Friday. A cold front will move through Saturday dropping temperatures below normal this weekend and will continue into next week. The cold front will not move through central and eastern AZ until late Saturday, so temperatures will remain above normal for those areas on Saturday. A second weather system will move through during the middle of next week, dropping temperatures well below normal.
Model guidance shows the potential for additional weather systems to move through the region next week. This is reflected in the latest CPC 6-10 day outlook, which shows 60-70% probabilities for wetter than normal conditions and 40-60% chance of below normal temperatures across much of the Southwest US.
