Cooler-than-normal seasonal temperatures sweeping across much of the nation this week are expected to extend through the Labor Day weekend.
Seasonal or below-average high temperatures will persist for millions of people in the Midwest, South and East. Nearly everywhere east of the Rocky Mountains could see high temperatures 5 to 15 degrees below normal for the first week of September.
Highs are expected to only climb to the 80s from Dallas to Atlanta and Jacksonville, Florida.
In the Northeast, New York City and Boston are forecast to see highs in the 70s over the holiday weekend. Similar cool temperatures are in store for the Midwest, including the cities of Chicago, Omaha, Nebraska, and Rapid City, South Dakota.
In the West, seasonal or warmer-than-normal temperatures are expected to continue. High temperatures are expected to top triple digits from Phoenix, Arizona, to Las Vegas. Salt Lake City, Utah, Boise, Idaho, and most of Montana are expected to see temperatures in the 90s over the Labor Day weekend.
The hot weather in the West will follow monsoon conditions that have brought the wettest days of the year, so far, to some areas across the region and supplied much-needed rain to drought-stricken areas.
On Wednesday, an increased threat of flooding will mostly be in Idaho. A flood watch is also in effect on Wednesday for parts of California, Utah, Oregon and Montana.
On Wednesday night, there is a threat for heavy rain from Colorado through much of Kansas and into southwestern Missouri and northwestern Arkansas.
Holiday weekend temperatures in Florida are expected to remain mostly seasonal, with highs in the 80s and 90s. But rain is also expected in the Sunshine State over the weekend.
A storm front sitting over the state is forecast to remain stationary, bringing rounds of showers and thunderstorms across the region throughout the weekend. Between 2 inches to 5 inches of rain is expected across Florida this weekend.
Other areas that could see rain over the holiday weekend include New Mexico and West Texas.
Passing showers are also across the Gulf Coast on Saturday and Sunday, but drier conditions are expected on Monday.
Holiday beachgoers along the Atlantic Coast will also encounter cooler-than-average temperatures as the unofficial end to summer bows out with a cool note.
