 And again, a couple strong and severe storms certainly cannot be ruled out. It is a refreshing air mass, a cooler, drier one that will make its way all the way down into Texas and Oklahoma, taking the edge off heat and humidity there and then covering a wide area of the heartland over the second half of the week with pleasant nights, mild to warm days, no stress or strain on the back 40. There will be welcome rains along that boundary over areas of the Mississippi Valley, lower Mississippi Valley, the Delta region into the southeast and mid-Atlantic.
