A cold front will push south across the Western U.S. into Tuesday with mountain snow and areas of gusty to high winds. An area of low pressure will form along this front on Tuesday and bring a potential for severe thunderstorms with tornadoes and excessive rainfall in the lower to mid Mississippi River Valley. To the north, heavy snow is possible in parts of the upper Midwest. Read More >

| Figure 1: Afternoon visible satellite and key features | Figure 2: Wake low observations during the evening. A wake low can form on the backside of a well-defined thunderstorm complex and cause the winds to abruptly turn direction and re-increase in speeds, despite the storms having passed. You may have noticed these if you went out to glance at the picturesque sunset, especially over the Chicago metro area where the gusty southeast winds persisted for about 30-45 minutes. | Figure 3: More wake low observations from the Chicago Harrison-Dever Crib located just offshore downtown Chicago. |
