Special Weather StatementIssued by the National Weather Service at 1:15 PM PDT on July 5, 2008
... Very hot temperatures expected next week...
A strong ridge of high pressure developing over the central Pacific Ocean will build east and strengthen next week. This will likely bring very hot conditions to southwest California... with the potential for near record high temperatures during the middle of next week.
A warming trend should begin on Monday and persist into midweek. Temperatures will climb near to or exceed 105 degrees in the deserts on Monday... with coastal... valley... and mountain areas warming as well. The marine layer will likely remain confined to the beaches and coastal waters by Tuesday... with temperatures soaring across inland areas. Temperatures on Tuesday will approach or exceed 105 in the warmest valleys and foothills and up to around 110 degrees in the Antelope Valley. At the coastal sections... temperatures will generally range from the 70s at the beaches... to around 90 inland... with foothill locations likely approaching 100 degrees. Heat index values will likely exceed 100 degrees on Tuesday in the Valley... Mountain... and desert locations.
By midweek... the warming trend should start to level off... with temperatures remaining around tuesdays afternoon high temperatures. Though the warming trend will level off... an increase of monsoonal moisture from the southeast will likely keep heat index values above 100 degrees on Wednesday in the Valley... Mountain... and desert areas.
Hot and humid conditions will likely persist for late week... despite an increase in cloud cover. Though afternoon high temperatures will likely decrease... heat index values will likely remain above 100 degrees for Thursday and increased moisture will make the human body perceive it to be nearly as hot.
The increase in monsoonal moisture will bring a slight chance of thunderstorms to the mountains and deserts from Wednesday through Friday.
During the heat wave... persons are urged to never leave children or animals in parked vehicles even with the windows cracked... death will likely result. Continue to drink plenty of fluids... stay out of the sunshine... and check up on relatives and neighbors.
