southern two thirds. a line of thunderstorms will push across the
lake into early saturday morning along a developing front.
isolated gusty, erratic winds are possible underneath

shower and thunderstorm potential through monday night/tuesday. 
then high pressure looks to build in midweek behind the early 
week low pressure system.
