A strong southwest flow will establish itself over Illinois today and persist through Tuesday into Wednesday. Chicago's high temperatures today may end up some 10 degrees higher than the mid 50s experienced Sunday. On Tuesday, the warming will continue with unseasonable 70-degree readings forecast. On Halloween, some cloudiness may precede and accompany a cold front that is not expected to pass through Chicago until later in the afternoon. A much cooler air mass should then be in place the remainder of the week.
Meanwhile, Tropical Storm Noel formed just south of Hispaniola, and Sunday night the National Hurricane Center in Miami forecasted a slow-moving northward track which left Haiti, the Dominican Republic, southeast Cuba and Jamaica bracing for a foot or more of rain, extensive flooding and mudslides. Haiti was under a Tropical Storm Warning, and a Tropical Storm Warning and Hurricane Watch were in effect for southeastern Cuba.
