Much warmer temperatures are expected by mid-week. Another storm system is expected to pass north of AZ late in the week, producing breezy conditions & slightly cooler temperatures. No precipitation is expected from this system. --Revised long range forecasts were issued by the CPC last week. The forecast for June shows a weak (SW AZ) to moderate (rest of AZ) bias for above normal June temperatures. The long range forecast for the monsoon (Jul-Sep) is similar. There is no bias in the precipitation forecasts for June & the monsoon season, suggesting near normal precipitation in the coming months. Note that long range forecast models rarely show a precipitation bias during the monsoon. -N fertilizer should be applied in split applications between pinhead square & early bloom (700-1200 HU after planting).
