High pressure will continue with subtle changes in the day to day forecast through Saturday. Patches of fog will be possible each morning in the valley but the extent continues to look limited in the near term. Areas of frost likely the next several mornings. For today a light north wind will help to keep temperatures warmer than normal.
A weak low pressure area is forecast to move through Southern California late Friday and Saturday. Conditions will remain dry with the only difference we may see is an increase in high clouds late this week.
Models still indicating the main part of a trough staying mainly north with maybe some showers over parts of Shasta county late Sunday and Sunday night.
Extended Discussion (Monday through Thursday)
Models continue with a dry forecast next week. A deep trough will move through the Great Basin Tuesday and Tuesday night. This may lead to breezy to windy north winds for the valley to northeast to east winds in the mountains Tuesday and Tuesday night. Clusters are in support of the deeper than normal trough.
Other than the winds and dry weather there should be some cooling of temperatures in the mountains next week by about 10 degrees.
