Thunder rumbled through the eastern portion of the Imperial Valley late Friday afternoon, bringing rain, wind and lightning to some areas of the county.
Perhaps the thunder served as an ominous drum roll for what is to come Sunday through Wednesday: temperatures reaching from 105 to 108 degrees.
Friday's storm, which was expected to pass through the Imperial Valley later that evening, moved into the area from the southern Pacific, said Imperial County meteorologist Jim Christopherson. It moved into the Valley from Mexico, and was expected to move into Arizona today.
Christopherson said to expect cloudy skies Saturday, with the real heat to arrive Sunday. He said the higher temperatures have nothing to do with Friday's storm.
