A rain free morning? Take a picture....
Last day of May actually starts rain free...but humid! A little sun plus a PM disturbance will trigger storms, some strong (isol. severe:wind, hail). Best chances are DFW west & north. Those storms will die off this evening.
HOWEVER, another strong complex will spin out of west Texas into our area late tonight into Wed. AM. Widespread rain may create a flooding issue if any stall.
After Wed. AM, we watch a cold front PLUS an upper level low which will both hang out in Texas all week into at least Saturday. That means continued rain chances...not so much severe storms, as heavy rain and flooding. It will not rain ALL the time though.
Indications are this feature should sink far enough south Sunday to dry us out into early next week. These types of systems are NOT well forecast more than a couple of days out, so timing will definitely change.
