Daily thunderstorm chances are in the forecast through this weekend with locally heavy rain possible. Smoke and haze from nearby wildfires will also continue. Temperatures will be variable, but generally within 5 degrees of normal, outside of this weekend which will be cooler. Drier conditions with the return to more typical westerly winds arrives around August 3-4.
No major changes to the overall forecast thinking.
Thunderstorm chances continue the remainder of the week and into the weekend as a surge of moisture moves into the region. PWATs max out Friday into Saturday, reaching the 0.8-1.1" mark based on ensemble guidance. Expect storm coverage to increase from south to north the next several days with localized heavy rainfall and flash flooding a possibility. This is especially true for recent high risk burn scars and ongoing wildfires, including, but not limited to: Tamarack, Beckwourth, Numbers/Monarch, and Sheep. Winds in excess of 45 mph also remain a possibility from thunderstorm outflow winds each day.
While this environment is ripe for heavy raining thunderstorms, it can also lead to early storm initiation putting a lid on stronger storms as the region clouds over. This would bring more showers with less thunderstorms. This doesn't look to be much of a problem today or Friday, but could occur Saturday, especially if nocturnal showers continue Friday night. We are most likely to see overnight shower activity Saturday night, so am expecting less coverage on Sunday. Storms will also be pushed eastward Sunday as southwest flow increases ahead of a trough approaching the west coast.
A drier and more stable airmass results from the trough moving onto the northern California coast, limiting thunderstorm coverage on Monday. A few storms remain possible for areas closer to the Oregon border and near/east of US-95. This trough will become the dominant weather feature for the start of August, with a dry airmass in place and typical westerly afternoon/evening breezes starting around August 3.
On the smoke front, the Dixie Fire remains the primary contributor. While conditions have certainly improved from a few days ago, there remains a couple wildcards -- 1) Burn out operations currently ongoing to establish better containment lines on the fire, which may produce additional smoke. 2) Thunderstorms and the unknowns with rain amounts and outflow winds. The forecast is based heavily on the HRRR smoke model runs, which keeps the worst conditions immediately downwind of the fire. This includes Lake Almanor, Portola, Susanville, and the Honey Lake Basin. Southerly flow may push smoke north toward the Lassen Forest and Eagle Lake areas during the day with drainage winds at night bringing the return of hazy conditions to the Tahoe Basin and portions of the Greater Reno Area.

Two main aviation concerns remain thunderstorms and smoke/haze from ongoing wildfires.
Storms are expected to initiate today for areas south of US-50 between 19-21z, expanding northward through the afternoon. Showers may continue through approximately 09z, though most storms are likely to wind down by 04-06z tonight. Most area terminals will be impacted from these storms, whether it be from heavy rain, lowering cigs/vis, and outflow winds potentially exceeding 40 kts. The strongest winds are likely into the Nevada Basin and Range, with the heaviest rain potential in the Sierra and western Nevada near/south of I-80. Anticipate areas with mountain obscuration due to the storms, especially in the Sierra. Additional showers and thunderstorms are expected Friday through Sunday as well.
As far as smoke, the Dixie Fire remains the primary contributor. The worst conditions remain around Lake Almanor, Portola, Susanville, and the Honey Lake Basin. Otherwise, general haze and slantwise visibility reductions will remain across the region. For more details about the smoke forecast, please see the discussion above. -Dawn
