14 hours, 57 minutes of daylight today in the Twin Cities.
Near 90 Today - Sunday: Wettest Day. The weekend won't be a total loss, but have a viable Plan B for late Saturday and Sunday, which (based on the fairly reliable ECMWF data) appears to be the wetter day of the weekend, temperatures 10-20 degrees cooler than Saturday.
Weekend Weather Details. Rest assured - those temperatures are in Celsius. The best chance of significant rain: late Saturday into mid afternoon Sunday, as a slow-moving cool front pushes across Minnesota. Your best odds of salvaging some dry weather this weekend? Saturday morning, and late in the day Sunday, after the dinner hour. Data courtesy of ECMWF.
Weekend Rainfall Outlook. The latest NAM model predicts the heaviest rains (.5 to 1") over western and northern Minnesota.
Timing The Rain. The models print out the most significant rain (showery rain and embedded thunderstorms, some possibly heavy) from late Saturday into Sunday morning. Graph: University of Iowa Meteorology Department.
90 Possible Today and Saturday. Models are in pretty good alignment. Assuming the sun is out much of today and at least the first half of tomorrow, we stand a good chance of reaching the 90-degree barrier both days, followed by a noticeable cool-down on Sunday. HIghs next week will be more moderate, generally in the 70s to near 80 by the end of the week.
Answer: "Thomas Schlatter, a NOAA scientist and contributor to Weatherwise magazine addressed this question in a past issue. Of course the answer is highly dependent on cloud volume. But consider a cumulus cloud with a volume of one cubic mile (1 mile wide, 1 mile long, and 1 mile deep) and a water content of 1 gram/cubic meter. This would calculate to a weight of about 9 million pounds (nearly 1.1 million gallons). That's quite a load to remain suspended in the atmosphere, but of course it does, primarily because of the droplet size and the updraft winds that hold these water droplets aloft until they reach a critical mass."

Health officials believe the employee then left her station, and other workers continued to fill orders before they became aware of what happened."
Warming Up. Yesterday was only the appetizer - the main course (of heat and humidity) comes later today and tomorrow. In spite of clouds lingering into mid afternoon highs reached 86 at St. Cloud, 83 in the Twin Cities, 91 at Alexandria and 92 at Redwood Falls.
