Weekly Highlights July 21st to 26th

This week the heat and humidity return to the Plains and Midwest, and we see storms throughout the Plains. Monday to Wednesday, severe storms look to break out in the Northern Plains into the Upper Great Lakes. The heat will be pushing the severe weather to the north this week. Dew point temps will be high mid-week in the Upper Plains into the Upper Great Lakes, so it would not surprise me to see some tornadoes across MN and WI. This week over the Plains we need to watch out for some nocturnal thunderstorms to develop overnight into the early morning hours. The low-level jet will bring warm moist air from the Gulf into the Plains and provide the fuel to erupt some thunderstorms. Wednesday, from Denver across the Plains some severe storms look to develop. The Eastern portion of Colorado has seen some tornadoes develop over the last few weeks and could see some more develop again on Wednesday. Thursday, some nocturnal thunderstorms will develop in the overnight hours and lead to more storms out across the Plains and into the Midwest. The Plains, Texas, and the Midwest will see hot and humid conditions return. Some areas could see temps close to and over 100 degrees, with the heat index over 100 degrees in some areas. Friday into Saturday, storms will develop in the Great Lakes and into parts of the Northeast, with some of those storms being severe. Also on Friday, some showers and thunderstorms will impact the Southeast. The Mid-Atlantic States this week look to be a little calmer from the daily chances of thunderstorms they have been having over the last few weeks. In the Four Corner States this week, more of the monsoonal flow will be bringing daily rains, and possible flooding to the area. Still watching the tropics this week as we will see if something forms, but there continues to be strong wind shear. Out in the West, dry and sunny conditions will continue this week.
