"We start off even cooler tomorrow morning, hard to believe that, but it is the case," Woods said.

Similar temperatures will remain during the work-week before the weekend.

"We have above-normal temperatures as we head toward the upcoming weekend, with the sun," Woods said.

What is La Niña weather? Will it arrive in time for winter?

La Niña is still running late, and when it finally gets here, it doesn’t look like it’s now going to stick around very long, and that could adjust some of the winter seasonal outlooks.

"A weaker La Niña implies that it would be less likely to result in conventional winter impacts," NOAA wrote in its October forecast update. "Though predictable signals could still influence the forecast guidance."

If La Niña conditions do arrive in time for winter, that would usually bring an overall wetter, cooler winter to the northern US and a drier, milder winter to the South.

But with now a weak La Niña expected, the pattern may not have as much of a significant influence.  In that case, if neutral phase conditions hold, there are fewer kinks in the jet stream, meaning more regional patterns dominate local weather. A weak La Niña may just occasionally nudge the pattern toward La Niña favored conditions.
