Synopsis
Dry and warm weather through Friday with breezy northerly winds.
Active weather returns this weekend as a weather system drops down bringing showers, mountain snow, isolated thunderstorms, gusty winds and much cooler temperatures.

Current GOES-West infrared satellite imagery shows a few mid to high levels clouds passing over interior northern California this morning. Temperatures are currently in the mid 50s to low 60s in the Valley, mid 40s to mid 50s in the foothills, and 30s to 40s in the mountains, valid at 215 AM PDT. Breezy northerly winds will linger across the area today and into Friday, with wind gusts of 15 to 30 mph. Dry and warm weather continues through Friday. High temperatures are forecast to be in the 70s to low 80s in the Valley and foothills, with 50s to 70s in the mountains.

Confidence is increasing for a weather system to drop down from the Gulf of Alaska, bringing active weather over the weekend.
Widespread precipitation is in the forecast, in the form of Valley/foothill showers and mountain snow. QPF has trended higher, and the current guidance from WPC shows amounts of 0.50" to 1.50" in the Valley, 1" to 2" in the foothills, and 1.50" to 3" in the mountains from Friday night into Sunday morning. For snow, the National Blend of Models (NBM) shows a 40 to 80 percent probability of 6 inches of snow above 6000 feet, with a 45 to 75 percent probability of 8 inches of snow above 6500 feet from Saturday into early Sunday. Snow levels will initially be high, around 6000 to 8000 feet late Friday night or early Saturday morning. As cold air moves in, snow levels will lower through the day Saturday and then drop to around 3500 to 4000 feet Saturday night into early Sunday morning. A few lingering showers will be possible on Sunday, however the majority of precipitation is expected to fall on Saturday.

Isolated thunderstorms can also be anticipated for Saturday, with a 15 to 25 percent probability of thunderstorm development. Best chances would be in the afternoon and evening hours. Expect small hail, gusty winds, lightning and brief heavy rain with any thunderstorms that develop. Gusty southwest winds will also develop across the area on Saturday. Strongest winds will be in the northern/central Sacramento Valley, northeast foothills, and in the mountains. The NBM shows a 35 to 75 percent probability of wind gusts greater than 40 mph in the Valley/foothills, and a 65 to 95 percent probability in the mountains. Much cooler temperatures return to the area this weekend as the system moves through, with highs dropping to the 50s and 60s in the Valley and foothills.
