A Very Weak Stratospheric Polar Vortex is Forecast during September

In fact, we may be looking at a record weak stratospheric polar vortex forecast for early September, which is unusual as the vortex typically strengthens at this point in the season.

A weak Stratospheric Polar Vortex could disrupt the jet stream, making it more wavy. This may lead to early cold outbreaks in parts of North America, Europe, and Asia, with increased risks of storms or heavy precipitation over the next few weeks.

This sentiment is echoed by the CFS model's forecasting of relentless cold fronts dumping into the Eastern US through mid-September. (see previous post).

114 years ago yesterday, my all-time favorite photograph of a tornado was taken from Antler, North Dakota. On August 20th, 1911 this tornado, postmortemly rated F4, did damage just outside the town of Antler, moving up towards the Canadian border.

The church in this photo still stands today.

The next storm name on the list is Erin. The last time we had a hurricane Erin was in 2001 (there were 3 later instances of Erin but all of these remained tropical storms).

That storm turned away from the east coast & missed all land masses. It, however, holds a special place in my memory for this incredible satellite image captured of the storm on the morning of Sept 11, 2001.

The storm, off the east coast, brought north winds to the northeast US, providing blue skies during one of the worst days in American history. In the satellite, when zooming in, you can see smoke, getting pushed south by the circulation on the west side of Erin, south, into the Atlantic & parts of New Jersey.

Incredible image.
