.SYNOPSIS...

Low pressure of 29.7 inches centered near the southern tip of Lake

and a few rumbles of thunder will persist into tonight,
particularly across the southern half of the lake where there is

The low will continue to head northeastward tomorrow, as high
pressure of 30.0 inches builds in from the west. Breezy easterly
winds this afternoon will become northerly as the low moves away
tonight, with breezy northerly winds persisting on Wednesday.
Somewhat lighter east to northeast winds are likely on Thursday as
the high strengthens a bit to 30.1 inches and moves overhead.
