Summer Refuses to Budge; A Look at the opening of Autumn

In the past few weeks; some were looking forward for the autumn weather to arrive later this week via the calendar /Friday - September 22, 4:02 P.M. EDT/. I guess someone should let mom nature in on the change, since the weather has been and will continue to be nothing like our typical early autumn days. High temperatures are expected to rise well into the 80s to around 90 through the weekend and, at least into the early part of next week; well above the 70ish norms. High temperatures may flirt with/or may even challenge some record highs over the period but a few are tough nuts to crack.





This warm weather pattern is due to a strong summer-like ridge of high pressure blocking any cooler fall-like air masses from surging southeast into the Great Lakes and eastern half of the country.




By mid-week; a stronger jet core is progged to evolve into the trough as another upper low drops into the trough in the vicinity of North Dakota (above). As the system advances east, this is slated to push into the Lakes Region (below). Of course, this is days away but a notable change from this week.
 


Enjoy the several days of summer-like weather as indications are for more typical fall-like weather near the close of the month. However, this won't be the last of the above normal or warm weather as extended patterns indicate variable fluctuations in the prevailing jet stream early October.

Next we'll take that look back at the rather mediocre summer - in a few ways.
