HIGH PRESSURE AND DRY FRONTAL PASSAGES ALLOWED THE REGION TO REMAIN DRY THROUGH SATURDAY THE 30TH. SUMMERS WARMTH RETURNED THE LAST WEEK OF THE MONTH. A FEW THUNDERSTORMS ON THE 30TH AND 31ST BROUGHT AN END TO THIS DRY STRETCH...ONE THAT GAVE A BROWN TINT TO LOCAL LAWNS.

WINDS FOR THE MONTH WERE GENERALLY LIGHT AND WITH THE LIGHT SYNOPTIC FLOW THIS MONTH STRONG WIND GUSTS WERE LACKING FROM THUNDERSTORMS.
