Arctic Locked Up Another Week


Showers will be lighter as the system travels through the Delta and Southeast later this week, but could cause some disruption in the late stages of the cotton harvest.

Otherwise, shower chances will be few and far between across most of the country through early next week. A pesky cutoff low may produce some showers in Texas, but for the most part, dryness is in store. And despite a ridge-west and trough-east pattern, temperatures will increase country-wide early next week.

The trough is not connected to the Arctic, with the polar vortex remaining around Hudson Bay. And as such, its overall stagnation will show up in moderating temperatures. Looking a bit further into December, the pattern will eventually change and storm systems will move through the country again. But the majority of the growing regions will see a respite for the next seven to 10 days.

As we go further into December, the wheat will go dormant and we will watch the overall moisture supplies for the start of the 2021 growing season. This is especially true in the Central and Southern Plains, where dryness may continue to build due to the ongoing La Nina situation into next spring.
