Temperatures Friday through the weekend will be normal to a few degrees below normal.  Winds will south to southwest in the afternoon.

Models indicate another weak upper level low pressure trough brushing the north state Monday and Tuesday.  This system could trigger isolated thunderstorms north of Redding.
