Hurricane Iota raged toward Central America on November 16, 2020, as a Category 5 storm - the 30th named storm in a record-breaking season. In practice, the bar for this wet bulb temperature, which is measured by covering a thermometer with a wet cloth, is much lower - as shown by the deadly heat waves in Europe in 2003 that are estimated to have claimed 70,000 lives…” A “wet bulb” temperature of 35 degrees Celsius (95 degrees Fahrenheit) - which factors both heat and relative humidity - can be fatal after a few hours, even assuming ideal conditions such as unlimited drinking water, inactivity or shade. CNN.com has a reminder that the wet bulb temperature is even more accurate than the heat index when it comes to predicting the impact of heat on human health: “ The city, along with Ras Al Khaimah in the United Arab Emirates, has temporarily crossed the threshold beyond which the human body cannot sweat enough to cool itself down. “We have to act like it.” Pellegrino said the recent escalation of the drought has been “very scary” for some Vegas residents, although she insists the water authority has planned for this moment…” We are the driest city in the United States, in the driest state in the United States,” said Colby Pellegrino, deputy manager of resources for the Southern Nevada Water Authority. But Las Vegas, called “The Meadows” in Spanish due to its natural springs that were pumped dry by the 1960s, is at least aware of its setting in a place so arid that only a few small creosote bushes and tumbleweeds can survive here naturally.

If you were hoping for endless days of sunshine and 90s back in April, it looks like you got your wish. It’s not impossible, but it is unlikely.Įpicenter of Heatwave Remains Just South of Minnesota Into Early August. Triple digit heat is likely over the Dakotas and even Iowa, but the GFS has been much too warm in recent weeks, and I seriously doubt the metro area will see highs above 100F later this week. At the rate we’re going I don’t see how we wind up with anything less than 25 or 30 days of 90s in 2021.ĮCMWF Temperatures for MSP NOAA GFS Temperatures for MSP Models show fairly consistent 90s into at least the first half of next week, adding to the 15 days at or above 90F in the MSP metro so far this summer season. “It would take a lot of rain to get caught up…”īack to the 90s.

“It really doesn’t look like there’s any immediate relief,” Doneen said. “This is time to remind ourselves about how valuable water is,” said Randall Doneen, the DNR’s manager of conservation assistance and regulations. The deepening drought is turning the summer into a sobering lesson in resource conservation. Star Tribune reports here’s an excerpt: “… With about half of Minnesota now in the grip of severe drought - and 4% in extreme drought - the state has officially shifted into the “drought warning phase,” the state Department of Natural Resources (DNR) announced Friday. Me? I’m praying for rain.ĭrought Deepens in Minnesota – Watering Bans More Likely.

A real summer.īut it’s coming at a cost to agriculture and recreation. We’re getting our money’s worth of sunshine and heat this summer. NOAA’s GFS predicts a few 100-degree days but I doubt it. I’ll be shocked if most towns don’t have water restrictions or bans in place by mid-August, at the rate we’re going.Īlthough not as scorching as early June, the next 2 weeks bring incandescent, antiperspirant levels of heat, with a run of low to mid 90s. That seems unlikely, in spite of a few hit or miss T-storms in the forecast. We’ve always had floods and droughts, but the frequency and intensity of water extremes is rising with the mercury.Īccording to the Minnesota DNR it will take 3-5 inches of rain over 2 weeks to pull most of Minnesota out of serious drought. Wets are trending wetter and dries are getting drier. New England floods while the west burns and smoke turns Minnesota’s sky into L.A.
