An upper level trough of low pressure (the “U” shaped dip in the yellow line) is moving eastward and that means it will stay cool through the weekend then start to warm up again, but another trough will move in Wednesday and cool us off again. You can see the pattern, but it should stay dry. A weak surface front slid by Friday helping cool us off.
