Data from NOAA and NASA confirm that anyone under the age of 28 has never lived through a cooler than average month on Earth.
Our caveman DNA has us wired to prioritize what we can see outside our windows (or caves). It's more challenging to step back and track the big, global picture over time.
In recent days cities from Japan to China, South Korea, Austria and Slovenia have set all-time record highs, which makes our recent 3 week stretch of cool & comfortable all the more remarkable, and welcome. No complaints here.
Summer continues to simmer out west, and computer models push 80s into town from this weekend into much of next week; about 2-7F warmer than average. We go from simmer to sizzle the following week; long-range guidance showing a few 90s from the last week August into early September. A stray T-shower may sprout Friday, otherwise dry, increasingly warm & sticky weather prevails thru the middle of next week.
In today's weather blog: "Utor" pushes into China, some models bring a tropical depression or storm into the Gulf Coast by Saturday and flash floods continue to swamp a vast stretch of real estate from New York to Mobile.
I'm counting my weather-blessings.
What Month Is This Again? Much of the Northern Hemisphere continues to fry with all-time record highs from Japan, Korea and China to Austria, and unusually hot weather over much of Alaska. Then why is there a frost risk early this morning over the Minnesota Arrowhead? Polar amplification; huge north/south sweeps of the jet stream, a giant and persistent kink in steering winds aloft, pushing unsually warm air into Alaska and western Canada, while simultaneously guiding unusually chilly air southward into the northern tier states of the USA. Very strange for mid-August. Map above shows predicted wake-up tempeatures this morning up north, courtesy of the Duluth National Weather Service.
Smoke Creating Hazy Skies Across Much Of Western And Central North America. Yes, that milky-blue sky and cherry-red sunset is a pretty good tip-off of smoke, sweeping south out of Canada. Heres's an excerpt from a post at the local Twin Cities NWS site: "Forest fires across northwest Canada and portions of the western United States have produced a great deal of smoke over the past week. That smoke has been circulated by the atmosphere across much of the western portion of the continent, including the Upper Midwest. The large scale weather pattern will be changing some over the coming days, which could help to shift the smoke and hazy skies out of many locations. The image (above) provides an overview of the fire locations and smoke conditions this morning."

* Slight risk of a tropical wave/storm pushing into the Florida Panhandle by Saturday. Regardless, much of the Southeast will be soaked by 2-5" rains over the next 3-4 days with an ongoing risk of flash floods.
* Typhoon Utor will strike coastal China as a Category 2 hurricane (sustained winds of 100-110 mph) by Wednesday morning (US time), capable of a 5-10 foot storm surge and severe inland flooding.
* Extreme heat continues to grip much of China; slight relief forecast for Japan in the coming days.
Summary: Flash flooding is underway from Philadelphia into much of New Jersey, and conditions will not begin to improve until Wednesday. Travel and commerce will be impacted into Tuesday night. We're watching a tropical wave in well south of Cuba, which may drift north and enhance rainfall amounts over the Southeast USA from Thursday into Sunday. Significant flash flooding is expected from Mobile and Pensacola to Atlanta and Charleston, with a slight risk of tropical storm formation by late week. Meanwhile "Utor" spares Hong Kong and Macau, but a severe flood may be brewing for far southern China and northern Vietnam as Utor fizzles well inland later this week. Record heat continues to grip China, the worst in 140 years for much of the country. The typhoon will ease the heat in the south, but more superheated haze and pollution will make life very unpleasant from Bejing to Shanghai.

Map credit above: "This interactive shows just how warm average global temperatures have been over the past three decades, particularly on a backdrop of warming that extends back several decades, based on data reported in a recent WMO report. It shows the global average surface temperature (land and sea) for each decade since 1880, and the dotted line shows what the 30-year average was from 1961-1990. The numbers are an average of temperature records from the three main global surface data sets kept at the U.K.’s Hadley Center, at the National Oceanic and Atmospheric Administration (NOAA), as well as at NASA."
Did you know?
- Climate change gets us hot under the collar, making people around the globe more aggressive.
- More hot days mean ripe conditions for ground-level ozone, or smog, which forms when pollutants from tailpipes and smokestacks mix in sunny, stagnant conditions.
- With an average temperature of 77.6 degrees Fahrenheit in the contiguous U.S., the month of July surpassed the 20th century average by 3.3 degrees Fahrenheit and 2012 was the 10th hottest year ever.
- Despite the fact that 97 percent of scientists agree that climate change is real, this legislator insists that it is "not science" and that environmentalists are missing the potential upsides.
- Children, pregnant women, and the elderly are particularly vulnerable to heat because their bodies are not as good at regulating internal temperatures. Heat makes them sicker...."
