Active weather pattern brings more changes
The first arctic blast of the season hit early this week as the jet stream dove south from northern Canada. As another trough of low pressure digs onto the west coast this weekend, the jet stream will shift and the upper level winds will come in from the southwest. This will warm our temperatures considerably as surface winds shift to the south ahead of another strong cold front which will move through the area Sunday night.
Showers and a few thunderstorms are possible this weekend as upper level disturbances move in from the southwest. Temperatures will be unseasonably warm, reaching the 60s Saturday and lower 70s Sunday.
Another big drop in temperatures occurs Sunday night into Monday as the upper level winds shift to the north, sending colder air south for the start of next week.
