The National Weather System (NWS) says to expect some changes.

A weather disturbance is moving through the Southwest and that will result in isolated showers and breezy conditions for the Imperial and Yuma Valleys. Temperatures will also drop from near normal to below normal levels through the middle of the week. By the end of the week dry conditions and near normal temperatures will return. Monday may see some showers, mainly after 10AM and a high of about 61 degrees. The chance of showers will increase Monday night and begin to decrease by Tuesday.
