PORTLAND, Ore. (KOIN) – Have you heard of “Hotober” yet?
It’s a colloquial term being tossed around in other parts of the United States because of the extreme temperatures occurring across the southeast and midwest. With that in mind, it is partly the reason we are having such cool weather in the PNW. A strong mid-level subtropical ridge has been stubborn and it’s been preventing a more zonal flow to allow for more seasonable weather in our section of the United States.
Communities stretching all the way up to Illinois and Ohio have had record- high temperatures from 100 years ago being broken from the summer heat in fall. Here are some of the high temperatures dating back to the weekend across the continental U.S. Notice that the heat stretches up to New York where the temperature is at 92 degrees and the afternoon isn’t even over!
Well, with that heat over there, we are working with cold air in our direction. Look back to Sept. 29, where our high temperature was only 52 degrees, again, a record low high for the day and also matching the coldest September high temperature on record. At that time, places like Cincinnati were topping off in the mid-90s. Even with a quick drop in our high-temperature average toward the end of September and early October, this was something else.
The forecast is going to change by the end of the week. That high pressure we were discussing above, it’s going to break down allowing for moderate temperatures to take over for most of the United States. Bringing that touch of fall to others.
