Storm systems associated with this pattern will track north of AZ, resulting in little chance for precipitation. However, these systems will draw cooler air into AZ & generate windy conditions at times. --The most recent Ensemble Streamflow Prediction for the Colorado River calls for spring flow of 6,600,000 Acre Feet (92% of average) with more precipitation expected late this week. --Nitrogen fertilizer is best applied in split applications between pinhead square & peak bloom.
