August 27, 1992: A chilly night in Embarrass. The temperature dipped to 28 degrees.
1,260 miles of Florida coastline haven't been hit by a hurricane in nearly 10 years. According to The Weather Channel 40 percent of all U.S. land-falling hurricanes have struck Florida; that's 114 hurricanes between 1851 and 2010.
Sandy showed the destructive power of a Category 1 hurricane, yet in a recent survey 1 in 3 Floridians said they wouldn't evacuate for a Category 1 storm.
Our weather models do a fairly good job predicting hurricane track, but intensity is still difficult to forecast - a function of warm water, dry air and wind shear. The latest NOAA NHC track brings Erika near Miami as a Category 1 storm by Monday morning, but confidence levels are low. Florida's decade-long hurricane drought may soon come to an abrupt end.
I got my fill of Sweet Martha's Cookies at the State Fair yesterday. It would have been rude not to try a few dozen! Today looks like the coolest, wettest day in sight; heaviest rains and T-storms push across far southern Minnesota. The sun returns Saturday - daytime highs reach 85-90F from Sunday into most of next week.
The first week of September will feel like mid-July. Business as usual in the Land of 10,000 Crazy Weather Extremes.
"...The biggest short-term threat posed by Erika is very heavy rainfall over portions of the Leeward Islands, which should spread over the Virgin Islands and Puerto Rico tonight and early Friday. These rains could produce flash floods and mud slides. More than 12 inches of rain has fallen in Dominica, with reports of fatalities in that island..."
Big Variations Over 200 Miles. A fairly soggy day is shaping up for far southern Minnesota, while little or no rain is expected north and west of St. Cloud. As you drive north skies should brighten, but expect periods of rain and possible thunder from the Twin Cities to the Iowa border. Source: MPX National Weather Service.

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.
The Cheapest Oil Ever Still Won't Slow Down The Clean Energy Revolution. It's coming - remove all subsidies and let the markets work, and consumers decide. Here's a clip from Mashable: "...Renewable energy use grew an average of 5% per year during the period from 2001 to 2014, with major growth seen in wind and solar in particular, the Energy Information Administration, or EIA, reported. Renewable energy accounted for nearly 10% of the energy Americans used in 2014 — the highest usage since the 1930s, when many people still burned wood for heat. Yet, just as clean alternatives to fossil fuels pick up speed, they confront a powerful old nemesis: oil, now cheaper than ever. Petroleum prices have plummeted since late summer 2014, declining by more than 60% to a record low below $40 per barrel on Monday, before recovering slightly..." (Photo credit: Solar City).
