(NEXSTAR) – The start of fall may be just days away, but the weather forecast in many places isn't matching the calendar, and that could include parts of the Pacific Northwest as the seasons turn.

Summery weather is lingering in many states and is likely to stick around a bit longer. In fact, Oregon could see unusually warm temperatures days after the official start of fall next week. An updated forecast, released by the Climate Prediction Center Thursday, shows warmer-than-average temperatures predicted for most states between October and December.

The Southwest is most likely to see weather that's hotter than normal. Arizona, New Mexico and west Texas have a 60% to 70% chance of an abnormally warm fall, according to the seasonal outlook.

Most of the country is also leaning toward a warm season, with the chances generally growing stronger as you move south. The situation is less clear along the U.S.-Canada border; states shaded in white (below) have equal chances of a warm fall, cool fall, or average fall.

All of Washington and most of Oregon lands under the "equal chances" label for a warm fall, cool fall or average fall. However, a chunk of southeastern Oregon is leaning toward a warm seasonal outlook.

Meanwhile, the Southwest isn't just going to be hot – the forecast also predicts it will be dry. That could worsen drought conditions that are already starting to take hold in the region.

Northern states have the opposite outlook, leaning toward more precipitation than usual.

Those predictions are consistent with the La Niña phenomenon, which is expected to take hold in the next few months. La Niña tends to bring more rain to the Pacific Northwest and Ohio Valley, while keeping it drier in the southern half of the country.

All of Washington and most of Oregon fall under the "above chance" for precipitation; however, a chunk of the southern portion of the state falls under "equal chances" for above average, normal or below average precipitation levels.

As for Hawaii, which isn't pictured in the forecast maps above, the Climate Prediction Center expects the islands to see above-normal temperatures through the start of winter. Above-normal precipitation could come late in the year into early 2025.
