Expect warm conditions and sunshine as Santa Ana conditions ramp up temperatures in San Diego County this week, forecasters said.
Tuesday will be the hottest day of the week to the west of the mountains, where temperatures will run 10-20 degrees above normal, with highs in the mid-to-upper 80s inland, according to NBC 7 Meteorologist Dagmar Midcap.
High temperatures on Tuesday were expected to be in the low-80s along the coast and the mid- to low-80s inland, with periods of Santa Ana winds were expected.
The warm weather is expected to cool off heading into Friday, Saturday and Sunday as the offshore flow becomes stronger and San Diego County's next weather system moves in.

The county could possibly see rain by late Thursday and early Friday. Another small chance could be possible Saturday, when there will be much cooler temperatures.
Wednesday is predicted to be the transition day, with winds turning back onshore during the day, but still very warm, with inland areas mostly in the 80s. Lower deserts were likely see peak heat on Wednesday.
An upper trough could move into the West Coast and begin to influence the weather on Thursday with better onshore flow then and significant cooling.
By Friday and the weekend, the trough was expected to dig into the region, the NWS said. The trough position may determine whether rain occurs in Southern California.
