Unusual Steamy Weather Returning Soon


Aired 9/7/11

San Diego got a blast of tropical humidity to start the Labor day week, but things will be very different Wednesday.

The steamy weather moved out of the region Tuesday and more typical September weather has moved in. National Weather Service forecaster Robert Balfour tracked the systems exerting influence on the county.

"There is what we call a tropical wave. So that has been pushing moisture up toward us," said Balfour. "But at the same time we've had high pressure to the north, which is counteracting it. So San Diego County is the battle front where the two air masses are colliding."

That meant for lightning and thunder along with scattered rain showers.

San Diego is now getting a shot of typical fall conditions.

"Hot," Balfour summarized in a highly economical fashion. "Looks like temperatures are going to be in the 90's, if not pushing 100 in the inland valleys. That'll carry us through till Thursday; and then Friday, Saturday and Sunday we have a chance of more muggy weather."

The conditions on Monday and Tuesday morning were more reminiscent of weather in Hawaii or Florida. There was enough rain to create slick roads, but accumulations were under a tenth of an inch downtown, according to Balfour.
