Northern California is in the midst of a nice stretch of fall weather as an unseasonably strong area of high pressure has taken control of the weather pattern. This high pressure is steering storm systems to our north, so while Seattle and Portland see rain, the Golden State stays high and dry.
The next few days will be marked by chilly mornings and warm afternoons, both of which are typical conditions under a fall high pressure pattern. Another feature that is commonly associated with high pressure this time of year is patchy morning fog, which has developed the past few nights in the Sacramento and Delta areas. The fog will return to the area overnight, dropping visibility to around a mile in spots that are affected. By mid-morning Tuesday, however, the fog will be gone, leading to a nice warm up for the afternoon hours.
Enjoy the warm weather while it lasts, because all good things must come to an end. A Pacific storm system will push the high pressure eastward starting on Thursday. Cooler temperatures, increasing wind, and partly cloudy skies are expected for Thursday. Rain enters the forecast on Thursday night and Friday, starting in the northern half of the Valley. By Friday afternoon, the rain will spread southward into the Sacramento area, continuing into Saturday morning. The rain shouldn't be very heavy in the Sacramento area, but we could see up to a half of an inch of precipitation by the time all is said and done.
Nice weather returns for Sunday and early next week as high pressure returns. Along with the nice weather will come the fog, which may be more widespread next week due to a moist ground from Friday and Saturday's rains.
