TROPICAL MOISTURE THIS WEEK
A good swath of tropical moisture will feed in from the Gulf by midweek. This should enhance rain chances. Still, any development will be spotty, meaning not all of us will get rain. For those who do see a downpour, heavy rainfall can be expected. A lucky few could see up at an 1″ of rainfall. Severe weather is not anticipated.
