Erika Is No Lady
Beware of the Caribbean in late August and September. There's a reason why hotel rooms and cruises are slightly discounted: hurricane season peaks in the coming weeks.
September 10 is the date when a hurricane landfall is most likely, statistically, here in the U.S. - corresponding to peak ocean water temperatures. Hurricanes derive their energy from warm ocean water; the warmer the water the greater the potential for intensification.
In recent weeks wind shear, dry air aloft and Saharan dust has kept a lid on the tropics - at the same time we've seen a parade of Category 5 super-typhoons in the western Pacific - but that's changing. The latest model consensus brings a weak, Category 1 Hurricane Erika near Florida by next Monday. Uncertainty is high regarding track and intensity; the ECMWF curves the storm closer to the Carolinas.
Smoke from Washington wildfires left yesterday's sky an eerie shade of dirty-blue. Clouds increase today; heavy showers and T-storms slosh across southern Minnesota Friday with locally heavy rainfall possible. The sun should be out this weekend and daytime highs flirt with 90F from Sunday into much of next week.
NOAA's GFS model was right 2 weeks ago, hinting at a late-summer hot spell. Don't pack away the short shorts just yet.

More than 143 million Americans living in the 48 contiguous states are exposed to potentially damaging ground shaking from earthquakes. When the people living in the earthquake-prone areas of Alaska, Hawaii and U.S. territories are added, this number rises to nearly half of all Americans.
Wind Power Must Now Contend With Extreme Weather. More volatility in weather means more variance in average wind speeds; as reported by ClimateWire and Scientific American: "...California, Washington, Oregon and Texas, hotbeds for wind farms, had a particularly slow winter. Some regions saw winds around 50 percent lower than normal. Since then, conditions have started improving into early summer but have remained largely below average for most regions in the West, according to Vaisala. Lower winds mean turbines have been churning out less electricity. A U.S. Energy Information Administration analysis confirmed that wind farms in California, Oregon and Washington had been working at a reduced rate this spring compared with the five-year mean..."
