Crop Progress and Condition for the Week Ending August 2, 2015.
High pressure sat over the Great Basin, keeping cooler Pacific air from encroaching inland. Many locations reported their hottest temperatures of the summer this week. Temperatures soared to over 110 degrees in parts of the Central Valley as far north as Redding. Even the San Francisco area reported highs in the mid-90s during the middle of the week. Coastal locations typically received 70s and 80s and were the only locations to experience the moderating effects of Pacific air.
Valley locations sweltered in over 100 degree heat, while the deserts were typically around 100-110 degrees. The mountains were marginally cooler, but still received highs in the 90s at lower elevations. The highest elevations still reached into the upper 70s and lower 80s. Lows were more average, with 50s-60s along the coast, 70s in the valley, 80s in the desert, and 30s-60s in the mountains, depending on elevation.
By the weekend, hot afternoon temperatures had abated somewhat, with temperatures some 10 degrees cooler than during the week.
Rainfall was confined to isolated pockets in the southern and central Sierras on Friday and Saturday, with a few showers across the far north on Sunday. Rainfall amounts were very light, with no locations reporting over 0.5 inches. A few scattered showers fell in the southern deserts on Wednesday associated with the latest monsoon moisture surge, but nothing substantial. The rest of the state remained dry throughout the week. On Sunday, Pacific moisture moved inland, causing some isolated marine fog/stratus events along the immediate coast.

Rangeland continued to decline in nutritional value requiring supplemental feeding to maintain livestock. The majority of rangeland ponds were either dry or holding minimal amounts of water. The water table was falling drastically in most areas. Fire danger increased daily, and irrigation districts were limiting water distribution. In Sutter County, sheep continued to graze on levies. In Tulare County, foothill rangeland and forage were very poor at the lower elevations.
