The remnants of a strong typhoon are expected to develop into a super storm off southwest Alaska and then could help bring the Carolinas some of its coldest November weather in years, starting next week.
That is the scenario gaining favor among meteorologists and computer models this week.
Some guidance from the trusted Global and European computer models paint a picture of daytime highs in the 30s and morning lows around 20 degrees in the Charlotte area by the middle of next week, in fact.
How will all this happen?
It starts with Typhoon Nuri, which was a Category 5 storm with 180 mph winds before weakening northeast of Japan during the past day. Nuri is forecast to swing northeast, into the north Pacific, and head toward the Bering Sea as it morphs into a very powerful non-tropical system.
In its morning summary, the National Weather Service office in Anchorage said the Aleutians storm could set a record for lowest barometric pressure Friday. Winds in the western Aleutians are forecast to be at hurricane force, with waves of 43 feet or more.
This is where the forecast moves into the “theory” category.
Meteorologists have noticed in recent years that strong storm systems near Alaska can ripple the jet stream, causing a big dip from Alaska across western Canada and into the eastern United States. That is the recipe for blasts of cold air to push into areas east of the Mississippi River.
The computer models are picking up on this situation and are predicting a surge of cold air into the United States around Tuesday or Wednesday of next week. Typically, a pattern shift like this doesn’t go away quickly, and this could persist through the month of November.
Last weekend’s snowfall in the Carolinas, interestingly, was the work of the remnants of another former tropical system, Hurricane Ana, which had threatened Hawaii earlier.
