Discussion
A pre-frontal trough of low pressure will approach the region later today and then a strong cold front arrives in the overnight hours. Ahead of the trough and frontal system, there can be an occasional shower through the early-to-mid afternoon hours, but most of the time will be rain-free. The main action takes place late today and tonight as showers will become more likely and there can be a strong-to-severe thunderstorm as well. Skies will clear tomorrow morning and then a much cooler air mass will pour into the region tomorrow night and Sunday. In fact, the cool air mass arriving this weekend will be quite a bit below-normal for this time of year and the month of June could actually start off on quite a chilly note early Monday morning (June 1st) with temperatures bottoming out in the 40's across many of the northern and western suburbs.
