Temperatures will remain above normal through Tuesday with higher pressure over the area. Lower pressure will develop across much of the Western U.S. by the middle of the week and persist through the weekend. This will lead to temperatures cooling closer to seasonal levels and periods of breezy to locally windy conditions, particularly Tuesday-Wednesday. Dry conditions will prevail through the week.
Breezy to locally windy conditions will develop across parts of SE California and the Lower Colorado River Valley Tuesday afternoon with gusts generally 25-35 mph. Locally higher gusts near 50 mph are likely for areas of Southwestern Imperial County where a Wind Advisory has been posted.
