WEATHER UPDATE
════════════════════════════════
--Expect cool & breezy conditions as a trough of low pressure develops over
the Southwest this week. 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. For more details see publication az1243 at:
