The primary jet stream remains in the northwestern United States into southern Canada. This is separating the chilly air way up to the north and mild/warm air over much of the lower 48 states.
A storm system has been cut off from the main jet stream, and is located near Chicago. There is a cool pool of air and frequent showers with it. The combination of having warm air surrounding the storm and its location away from the main jet stream is keeping it from moving.
Over the next few days, this storm will just slowly drift through the Midwest and Great Lakes.
With that storm stuck, our area will continue under the influence of southerly winds, warm temps and moderate humidity. The moisture and humidity in place will allow for occasional storms with heavy downpours in spots.
This overall pattern is slated to change during next week, allowing more seasonable temperatures and humidity levels to return to the area by mid and late week.
