INLAND EMPIRE – (INT) - Heat warnings and advisories for much of inland Southern California will end as the week unfolds.

By Tuesday, afternoon temperatures should cool 5-to-12 degrees as a high pressure ridge weakens and is pushed east by a passing shortwave trough of low pressure.

Expect an increase in winds in the deserts on Tuesday and down the mountain slopes on Wednesday. More May Gray will push its way from the coast into the valleys.

Forecasters say the trough is not expected to have any moisture with it as the next 5-days remain dry.
