Risk of 80 Degrees
30 years ago much-maligned climate models showed wet areas getting wetter, dry areas getting even drier into the 21st century. It's amazing to see theory showing up on a daily basis on the weather maps.
If exceptional drought continues there's talk of another potential Dust Bowl for the southern Plains, hopefully not on a scale like the 1930s - the worst long-term environmental catastrophe to impact the USA. California is facing water shortages and another severe wildfire season, which pretty much runs year-round now. Meanwhile the Balkans just experienced 3 months of rain in 3 days, with historic flooding and mudslides.
The approach of an actual warm front sparked an MCS system yesterday, a meso-convective system that soaked the area with 1-3 inch rains. No need to water the yard anytime soon. The sun comes out today, and if we hit 80F it will be the first time since September 30, 2013. High pressure cools us off slightly by midweek, pushing storms south and west of Minnesota.
A warming trend kicks in by late week; highs may top 80F Saturday and Sunday. A return of southern moisture may fuel a few random T-storms Sunday into Memorial Day.
It'll be a lukewarm rain, though.

In fact, surging demand has overwhelmed companies that build the shelters." (AP Photo/Sue Ogrocki).

The Melting Isn't Glacial. Are we at a tipping point - or is the news coming out of West Antarctica and Greenland more "alarmist hype"? Are you willing to roll the dice? Here's a clip from a story at The New York Times: "...The ice sheets of Antarctica and Greenland together possess about 100 times as much ice as all of the mountain glaciers combined, but contribute only slightly more to the sea level rise: 310 billion tons a year, Dr. Scambos said. That is because most of the mountain glaciers lie in areas where temperatures are closer to the melting point than they are in Greenland or Antarctica, and so slight warming tips them to melting. Greenland, with 10 percent of the world’s ice, has enough to raise sea level by 23 feet. “I still think Greenland is the most important thing to watch for this century,” Dr. Scambos said..."
