Ample sunshine is expected the next few days across central Illinois, but we'll also have to dodge the occasional stray shower or isolated thunderstorm.

While we'll continue to enjoy typical summertime weather over the weekend and into early next week, there's a semi-permanent low pressure spinning over Hudson Bay in Canada. This deep low pressure has kept showers and clouds widespread in Ontario and Quebec. The impact for the U.S. will be smaller waves of energy spinning just outside the low's center. Some of these waves may reach Illinois and could spark an isolated shower or storm across the area in the coming days. The forecasting challenges are not only in the timing of these waves -- especially the further out in time with the extended forecast -- but also if the disturbance is strong enough to spark anything whatsoever in the way of precipitation.

The first wave will pass central Illinois late Friday afternoon with only an isolated chance for a shower or storm. A second wave passes by Saturday evening with a similar outcome. The best chance, which is still a slight chance happens Sunday evening or Monday. Similar disturbances may hang around through mid-week. Otherwise, we'll see mainly mostly sunny skies with near seasonable temperatures in the 80s throughout the extended and humidity levels starting to pick up a bit into early next week.

THE 7-DAY TEMPERATURE OUTLOOK:   Look for highs near 90 Friday; mid to upper 80s Saturday though Tuesday; and low 80s Wednesday and Thursday. Overnight lows will fall to the mid 60s Friday and Saturday night; upper 60s Sunday and Monday night; and low 60s Tuesday and Wednesday night.
