After a June that opened with record chill following a spring characterized by clouds, sub-normal temperatures and deluges of rain, Chicagoans increasingly anxious for summery warmth, sunshine and rain-free days must face another meteorological disappointment. A consensus of computer models suggests that below-average temperatures are likely to persist here through the week. In addition, persistent east winds blowing more often than not off the chilly waters of Lake Michigan will keep lakeshore areas especially cool in upcoming days. A good deal of sunshine today and Monday is just a tease. Another storm system is headed toward Chicago and the Midwest.
The bad news
In a weather situation more reminiscent of January than June, computer models indicate the development of a "closed upper low" over the Midwest. This feature is a large and slow-moving pool of chilly air 15-30 thousand feet aloft, beneath which the weather is mainly cloudy, showery and cool. That system arrives here Tuesday and persists into Saturday.
