From that animation, the lines of thunderstorms are possibly severe each day. Just for today and tomorrow, here are the outlooks.

Too much is enough. The total rainfall on the way is quite impressive for the Northern U.S. and Texas. That’s a lot of water in both cases. These three maps show the total estimated precipitation on the way for this week, with two regions zoomed in. Heavy pockets of moisture for the far southern Canadian Prairies, too. Notice the 6-12 inches headed to much of South Texas! There will be areas of the country that flood this week.

It’s a scorcher! Record temperatures to be threatened/set this week:

So, between heat and rainfall, your feeds will have lots of weather headlines appear this week. For me, I’m about to start begging for rain in my area - the pastures are getting crisp. For Colorado folks, I posted your outlook on Weather5280 this morning. That’s this week’s weather brief, I hope you have a great week. - Matt.
