The California Crop Weather report from the National Agricultural Statistics Service Field Office in Sacramento, Calif., released April 17, 2012.
A high pressure system brought dry conditions to most of California at the start of the week of April 9. Very dry conditions were reported across Southern California.
A low pressure system in the Gulf of Alaska slowly edged toward the Northern California Coast.As it approached, it generated some showers across the far northern coastal region on Monday and Tuesday while the rest of the state remained dry with very mild temperatures.Eventually, the low pressure system moved closer and finally brought rain to most of the state by Wednesday.
On Thursday, most of the state was in between storm systems as the first system moved to the east and another low pressure system developed in the Gulf of Alaska.The new system moved ashore late Thursday and spread showers first across Northern California and then into Southern California by Friday.These storms also brought significant snowfall to the Sierra Nevada Mountains.
Saturday included some residual shower activity across the state as the low pressure moved eastward.By Sunday, high pressure began to build along the West Coast and brought a dry and mild weather pattern to California.
Recent rain showers have improved soil moisture supplies for dryland crops.Early planted grain fields grew well with wheat heading at nearly two-thirds complete and some cutting for oat hay underway.
Wheat conditions continued to improve with recent precipitation as the crop was rated mostly good to excellent.
Seedbed preparations for corn and cotton were halted in some rain affected areas. The main activities included cultivation, herbicide applications, and reshaping seed beds.Some operators started planting.However, the majority of operators were waiting for warmer soil temperatures.
