Cool and dry through Friday with widespread freezing low temperatures in the early morning hours. Temperatures trend warmer this weekend. Another round of unsettled weather possible early next week. Freeze Warning in effect from 9 AM this morning to 9 AM PST Friday.

Freezing Temperatures on Friday


Clear and cold the next couple of days. This morning will be the coldest of the mornings moving forward. Many low temperatures in the valley area expected to bottom out in the mid to upper 20s. There will likely be near record low temperatures this morning which were all set back in 2018.

A little bit more moisture is expected to be around tonight with dewpoints coming up to help warm overnight lows a little bit. The trend will continue into Saturday with overnight lows warming a little bit more over Friday morning.

Minimum Temperature Loop

Daytime highs will start to warm only slightly today but have greater warming on Friday with generally temperatures topping out around 3 to 6 degrees warming than today.

Continued warming is also expected for Saturday but a couple of degrees for most locations.

Models are in good agreement with a shortwave moving through the region on Sunday. The depth of the shortwave varies with the models but both GFS and NAM are indicating at least a little bit of precipitation with the NAM having the deeper trough.

Precipitation amounts are very light so no major impacts are expected but a few showers down to around Sacramento look possible at this time.

Extended Discussion (Monday through Thursday)

Monday through Thursday the models diverge and there is high uncertainty during this time frame. In general they are indicating precipitation focused on the Pacific Northwest.

Cluster analysis does keep activity moving into the Pacific Northwest with maybe the tail end of these shortwaves just skirting our northern areas to bring some precipitation at times. Any precipitation would most likely be confined to the northern coastal range and maybe Shasta County.
