.DISCUSSION...
High pressure remains in control as very hot temperatures 
continue across the area. Some gusty winds materialized overnight 
across the southern and central mountains and Four Corners region 
and are expected again tonight. A few showers and storms will be 
possible over the San Juans this afternoon with gusty outflow 
winds being the main concern. Moisture starts streaming into the 
area next week bringing increasing chances each day for afternoon 
showers and storms.
