The first weekend of June has been a stormy one across the Northern and High Plains and severe thunderstorms will again be possible in portions of the region today (Monday).  Large hail and damaging winds will present the biggest threat to life and property, but isolated tornadoes will be possible as well. A vigorous trough will push into the western United States, creating this unsettled weather pattern.  Ahead of the trough and surface cold front, temperatures are expected to be in the 80s and 90s---quite hot---across the Great Plains.  Moisture transported from the Gulf of Mexico thanks to southerly winds will make it noticeably humid as well. The temperature, humidity, winds, and fronts will all come together and create an energetic environment for thunderstorm development. Most of the afternoon will be dry as a cold front slowly moves to the east. In the late afternoon, a few thunderstorms will develop along the front. With heat and humidity climbing ahead of the front, storm coverage and intensity will increase into the evening. Severe storms will be possible along and ahead of the cold front through the night.
