Forecast: Sunny, clear and cool

It will be mostly sunny, clear and chilly across the Southland today as cold air blasting from Alaska keeps temperatures below normal, the National Weather Service said.

The frosty conditions will continue through Wednesday, as another low-pressure system moves into the region, bringing a 20% chance of showers. Temperatures for most of the region will be in the upper 50s. It will be partly cloudy tonight with lows in the low to mid-40s. 

A wind advisory is in effect until 3 p.m. for the local mountains, where scattered showers are expected  across the northern slopes, coupled with northern winds gusting up to 50 mph. Highs for communities near the mountains will be in the mid-40s to lower 50s and in the low to mid-30s at higher elevations.
