A cold front will cross the Great Lakes and Northeast U.S. through Monday with gusty winds and areas of rain showers. A strong atmospheric river is expected to move into the Pacific Northwest by midweek bringing a threat for moderate to heavy rainfall, gusty winds, and mountain snows for parts of Washington, Oregon, northern California, and the Sierra Nevada.

Overview
An easterly flow of moist, unstable air was in place across the High Plains. Easterly flow brought this instability to the foothills of the Rockies where numerous thunderstorms developed in the afternoon and early evening. Winds aloft where out of the west in excess of 60 mph, creating strong wind shear needed for severe thunderstorms to develop. Several rotating storms called supercells formed in eastern Colorado causing baseball size hail, at least 1 tornado and a measured 97 mph wind gust at the Burlington airport. The image below is a visible satellite image taken at 201 PM MDT. If you look close you can see an area of developing cumulus over the Goodland area that would represent the area of strongest instability, where the strongest storms eventually moved along.
