General Weather Discussion for the Week Ahead

A frontal boundary over far northern Illinois and southern Wisconsin will waver back and forth through much of the region with possibly a few waves of showers and t-storms over the next few days. A few of these may occur today with the possibility of locally heavy rain over parts of northeast Illinois.

It should be noted that any storms that do occur could easily become strong to severe as there is a lot of upper-level support and jet-stream energy to work with. The main risk from these storms would be gusty winds, very heavy downpours and dangerous cloud to ground lightning. Perhaps the best chance of storms will be later this evening and into the first half of Saturday and again Sunday afternoon and evening. The risk of storms will continue through Sunday night, then the frontal boundary will settle south and stay south of our area for several days.

High pressure will then build into the Upper Midwest late Sunday night and into Monday bringing a less humid airmass to our area. The best chance of showers will be just south of the metro area on Monday with skies clearing from north to south. In fact, several quiet days can be expected next week with the best chance of t-storms occurring over Plains. These storms will stay well to our southwest with a good amount of sunshine in our area.

There are signs that the heat and humidity may begin to return to the area around July 29 or July 30 with perhaps some isolated t-storms moving into from the west and northwest. The first week of August also looks hot with hit and miss showers and t-storms as we possibly head back into an active pattern.
