KEY MESSAGES

- Elevated Fire Weather Conditions today through Saturday within the Burney Basin due to low RH and breezy westerly winds.

- Dry and with seasonable high temperatures through the weekend into next week.

DISCUSSION

Upper level trough continues to dig into the Pacific Northwest and Northwestern California today through late Saturday. Radar has light reflectivity within portions of northern California, however there is no instability and conditions are dry in the low and mid levels. This is resulting in just scattered to broken clouds, with virga at times. The lack of instability and forcing is helping to prevent isolated thunderstorm potential. The best chances lie over the crest and toward the east where instability and forcing are more favorable.

Otherwise, satellite shows few clouds across most of the Sacramento Valley, adjacent terrain, and into the San Joaquin Valley this afternoon. Temperatures reach into the upper 80s to lower 90s today, with cooling conditions near the Delta later this evening.

As the trough moves east through the region, breezy conditions are expected at times within the northeastern foothills and into the Burney Basin. Highest chance to see up to 30kt gusts will be within the Burney Basin. This combined with already low RH values in the teens to lower 20s creates Elevated Fire Weather Conditions today. There will be some overnight recovery in RH values tonight. Winds will continue to be breezy Saturday with RH values in the the teens to 20s continuing the Elevated Fire Weather Concerns for the Burney Basin. Breezy onshore flow will be likely within the Delta helping to cool temperatures during the late afternoon, evening and overnight hours. Cooler evening temperatures will be predominately around the Delta, southern Sacramento Valley and into the northern San Joaquin Valley. Otherwise, as we move past the weekend and into next week the pattern aloft looks to remain in place helping to keep seasonal temperatures with dry weather conditions.

AVIATION

VFR conditions continue through the TAF period, with SCT clouds moving through the Sacramento sites and RBL/RDD. Conditions remain dry helping to evaporate precipitation before it reaches the surface near RDD today. Skies will clear out slowly this afternoon/evening. Otherwise, breezy conditions near the Delta this evening and overnight. A few gusts to 15kts for the Sacramento Sites, MOD, and SCK this evening.
