In a few days there will be an abridged version of last winter’s polar vortex (meteorologists are split on using this term for the event) descending into the Eastern two-thirds of the country…
As for next week’s weather, polar air will again be spilling southward from the Arctic Ocean. That’ll be good enough to convert what’s typically Chicago’s hottest week of the year to an unseasonably pleasant early Autumn-style respite that will have folks begging for more. Chicago’s forecast high of 72 degrees Fahrenheit next Wednesday is historically much more likely to happen on September 16th than July 16th.
Cooler than normal weather is expected across much of the eastern two-thirds of the country as well, with mild temperatures from Boston to New York City to Washington, though not nearly as dramatic as in the Midwest. All in all, you really can’t ask for much better weather than what’s on offer next week.
So, what is causing this unusual cool air to descend? Typhoon Neoguri in the Pacific will alter jet stream patterns…
While the remnants of Typhoon Neoguri will not impact the U.S. directly, the large and powerful nature of this storm has set in motion a chain-reaction set of events that will dramatically alter the path of the jet stream and affect weather patterns across the entire Northern Hemisphere next week. Neoguri will cause an acceleration of the North Pacific jet stream, causing a large amount of warm, moist tropical air to push over the North Pacific. This will amplify a trough low pressure over Alaska, causing a ripple effect in the jet stream over western North America, where a strong ridge of high pressure will develop, and over the Midwestern U.S., where a strong trough of low pressure will form. This jet stream pattern is similar to the nasty “Polar Vortex” pattern that set up during the winter of 2014 over North America, and will cause an unusually cool third week of July over the portions of the Midwest and Ohio Valley, with temperatures 10 – 20°F below average.
Along with this surge of cooler air will come a surge of snarky climate denying trolls on the Internet comment boards. Most of these people probably will not be aware that with this break of summer heat in the East, the Western part of the country will have searing heat. Watch for phrases regarding Al Gore, emails/fraud, citing results from dark money studies, jokes about cow poop, predictions of cooling in the 70’s, climate change as religion, and so on. It is just boggles my mind that some think throwing out for discussion a few dissenting views will collapse a scientific consensus.
I am going to sit this round out on Social Media. But I do have a big supply of popcorn.
because of the previously predicted el Nino, we here in NM were expecting a wetter-than-lately summer. Now, that may not happen, and we need the rain. Badly.
It is as predictable as the sunrise.
