Expect temp- eratures to average 3-5 degrees above normal. Longer term forecasts indicate some moisture will enter the region by the weekend. This is not expected to be a major humidity event & should impact only central & eastern production areas. Any pre- cipitation is expected to be light and mostly associated with higher elevation areas. The long range forecast for the monsoon season (July-September) indicates a moderate bias for above normal temperatures & no bias relative to precipitation.
