pressure will develop over the central plains late monday. the low 
will deepen to 29.4 inches as it tracks northeast to the upper great 
lakes monday night into tuesday morning. as the system continues to 
track northeast toward james bay on tuesday, its associated cold 
front will approach the lake late tuesday.
