High pressure centered across the Great Lakes, providing a clear and cool start Thursday morning, will drift east toward New England. Under the high, temperatures started Thursday in the 40s and 50s across the Great Lakes region and that's what we'll have by Friday morning.
With recent rainfall and a mainly clear sky Thursday night into Friday morning, the combination will result in some thick fog in areas. Visibilities down to zero miles can be expected through the morning rush.
High pressure will provide sunshine through Saturday, but that will fade behind increasing clouds toward dusk. Rain showers are scheduled to return Saturday night into Sunday with isolated pockets of heavier rain. It won't be a washout but scattered showers may make outdoor plans damp. Isolated thunderstorms will still be around Monday and Tuesday as slow-moving low pressure keeps us cloudier. By Tuesday a cold front moving through will give us drier weather for Wednesday and Thursday.
