Discussion

Breeziness continues Saturday through Monday. That, combined with further drying of the soils will mean an uptrend in the risk of a dust related exceedance reaching the Moderate category Sunday and approaching Moderate on Saturday and Monday but otherwise in the Low category. Lighter winds are expected Tuesday and Wednesday for a Low risk but the morning inversions will be stronger and there will be more potential for short lived periods in the mornings to see somewhat elevated PM10 (dust) associated with agricultural activities ramping up before the inversion breaks.
