Currently in the Twin Cities — July 3, 2023: Hottest day of 2023 on Monday

The weather, currently.

Things are heating up for the next couple days even more. We will add to our tally of 90s for the season with potentially our hottest day yet this season Monday. Highs will likely reach the mid 90s Monday. A cold front will be the focus for thunderstorm development the next few days with most activity north and west Monday but an isolated late day storm is possible. Tuesday we’ll see widespread scattered storms potentially later in the day with possible severe storms. Behind the front it will be cooler, in the 70s to near 80 Wednesday and Thursday.

What you can do, currently.

The climate emergency doesn’t take the summer off. In fact — as we’ve been reporting — we’re heading into an El Niño that could challenge historical records and is already supercharging weather and climate impacts around the world.

When people understand the weather they are experiencing is caused by climate change it creates a more compelling call to action to do something about it.

If these emails mean something important to you — and more importantly, if the idea of being part of a community that’s building a weather service for the climate emergency means something important to you — please chip in just $5 a month to continue making this service possible.

Thank you!!

What you need to know, currently.

Twitter is breaking right as we're going into a big El Niño.

Over the weekend, Elon Musk instituted rate limits after a brief systemwide outage. As of Sunday evening, many Twitter users have been restricted to reading just 600 posts per day and viewers without a Twitter account are not able to read tweets at all.

All this worries Samantha Montano, a public emergency management expert and author of the book Disasterology. In a conversation with Gizmodo’s Molly Taft last fall, she explained how over the past 15+ years, Twitter has evolved into a critical resource for emergency managers around the world.

"We have not responded to any major disaster in the United States for almost two decades without Twitter and I do not want to know how a response would go without it," Montano said on social media on Saturday, after Musk’s policy change.

Twitter’s unique skill in disaster situations revolves around its near-effortless way of synthesizing first-hand information almost instantly. During the 2018 false-alarm missile alert in Hawaii, Twitter provided accurate information faster than the 38 minutes it took for the government to issue an all-clear, according to a study. There are also examples of tweets about earthquakes moving faster than the earthquake waves themselves, and therefore providing a real-time warning mechanism that can save lives. In an example from India in 2016, earthquake tweets were able to provide 4-6 minutes of warning before the shaking began in Delhi.

In fact, on Saturday afternoon, shortly after Musk instituted the new changes, a National Weather Service office in Southeast Virginia reported that they had lost access to viewing real-time damage reports during an ongoing severe weather outbreak.
