Gusty winds will whip through mountain and valley areas of the Southland amid cool temperatures Monday, but a warming trend is getting under way, likely to produce fire weather and near-record highs by week's end, forecasters said.
Along with gusty winds, isolated rain or snow showers are expected Monday on the northern slopes of mountain ranges in Ventura and Los Angeles counties, with the exception of the Santa Monica Mountains Recreational Area, according to a National Weather Service advisory.
The winds, which were below advisory level early Monday, will persist through Wednesday night, the advisory said.

NWS forecasts indicated a warming trend would start today, followed by a rise of a couple of degrees tomorrow, climaxing in temperatures on Friday reaching more than 20 degrees above today's.
