STUDIO CITY (CBSLA.com) — An approaching upper level trough was supposed to cool us down, but it doesn’t look like we are tapping into that on-shore flow all that much.

Temperatures Friday will be ever so slightly cooler, but it will still be sticky and humid. We are still seeing that surge of moisture from the Southwest. This will translate into a slight thunderstorm or heavy shower chance in the afternoon.

Otherwise look for temperatures to remain above average through the holiday weekend. This ridge of high pressure that has kept us so warm over the past several weeks will work back in by Monday and it will be warm again.

The only fly in the ointment of this forecast will be the track of Hurricane Ileana. One forecast model has it moving off to sea to the west…another has it being gobbled up in the trough…that would bring us some clouds and maybe a shower. We’ll have to watch its progression. Right now Labor Day looks pretty warm again.
