The title says it all. A massive high pressure system is moving slowly east and will be centering over the Great Lakes the next few days. High pressure means nice weather.
For Sunday, expect sunny skies. Highs will be seasonable in the low to mid 70s, but cooler north near Lake Superior under a light north wind with highs in the 60s.
Sunday night will be clear, calm, and cool. Lows will into the 40s.
There is a chance for aurora activity. Since conditions will be clear, it may be worth a glance upwards. Track updates at SpaceWeather.com.
Monday and Tuesday will see very similar conditions: sunny, light winds, highs in the low 70s, perhaps just a few degrees cooler than Sunday.
Wednesday will be a bit of a turning point. It's currently looking to be mostly sunny, but there is a chance for some rain by nighttime. Thursday, for the Fourth of July, there is a chance for some thundershowers, but it is still only a chance. We'll be keeping an eye on that day as it gets closer.
Elsewhere, this same high pressure system that's giving us nice weather is boiling the southwestern US. Death Valley, California is the hottest place on Earth. It holds the highest recorded temperature on Earth at 134 degrees set in 1913. Saturday's recorded high was 127. It may get even hotter through Tuesday, so that record is worth watching.
Also Saturday, Las Vegas, NV had a high of 115 and Phoenix, AZ had a high of 119, both of which tied or set new records. Excessive Heat Warnings are in effect in all three of those states.
Lightning Safety Awareness Week is now over, but I'll still have a few new indoor safety tips on the Sunday Late News. Otherwise, the National Weather Service has a huge resource for safety info, myths, and statistics on their website. As always, follow me on Facebook and Twitter for more!
