Isolated thunderstorms caused the fire activity to increase with down drafts and erratic winds.

Construct direct and indirect

line to secure fire perimeter.

Construct contingency lines in both zones.

Provide structure defense in communities at risk: Paxton, Greenville, Jonesville, Crescent Mills, Taylorsville, Canyondam, Butte Meadows, Bucks Lake, Meadows Valley, and

Greater Alamnor area.

East Zone:

Multiple firing operations

will continue.

Continue tactical patrol in the communities impacted by fire.

Fire behavior expected to increase due to drying conditions. Fire continues to move towards controls lines burning unburned interior islands and ridges. Most expected growth will be to the west towards Butte Meadows. On the East Zone expected areas to grow are Division Q(towards

the Emigrant Road) and Division X within the Bucks Wilderness area.

California Interagency Incident management team 2 (CIIMT 2) has command of the East Zone.

EAST ZONE:

Observed: Patchy dense smoke continued early this afternoon across the Dixie East Zone fire. Afternoon humidity values were beginning to drop into the lower 30 percent range with temperatures climbing into the upper 80s and low 90s. Terrain driven winds were beginning to intensify due

to less shading and increased sunshine.

Forecast: Hot dry and breezy conditions will continue this afternoon with humidity values falling down into the mid-teens to near 20 percent. Patches of smoke and haze will likely persist in some of the drainage basins and valleys. Highs will remain largely in the mid to upper 90s.

There is a less than 20 percent chance for isolated showers across Branches XX and XXIII. The lightning risk is low and the main concern will be gusty outflow winds.

For tonight dense smoke and haze will re-settle back into drainage basins resulting in poor visibilities. Overnight low temperatures are not expected to be quite as low in the valleys and drainages, but it'll likely remain chilly with temperatures in the 50s in spots. Overnight humidity values will range as great as 50 percent...even at higher elevations in spots to above 70 percent in the drainage bottoms.

WEST ZONE:

Strong upper level ridging will bring warm and dry conditions to the area through Fri with well above normal temperatures and worsening overnight RH recoveries along slopes and ridges. Isolated thunderstorms on Thu should stay well east of the fire area over the Sierra mountains though do have a chance of impacting the fire area on Fri. Increasing clouds with very slight chance of an isolated thunderstorms or light showers will lift north across the area Fri night and Sat with drier and winder conditions developing for Mon and Tue.
