The new decade is expected to begin with a lack of extreme cold or major storms across the United States -- but some partiers may still need a few extra layers or umbrellas on New Year's Eve.
Unsettled weather will largely be confined to the outer fringes of the nation as 2019 ends and 2020 begins.
"Much of the central U.S. looks fairly dry and tranquil, which will be good for traveling," AccuWeather Senior Meteorologist Brett Anderson said.
Here are eight detailed forecasts for celebrations in major cities across the country:

Millions of revelers pack Times Square each year to watch today's top artists perform on stage before the eagerly awaited ball drop at midnight.
No big storms nor blasts of cold air are anticipated for New York City this year, unlike the last two years.
"In the Deep South, the latest indications are that dry air will punch in and stick around for the middle days of the week with a few exceptions," according to AccuWeather Senior Meteorologist Alex Sosnowski.
This should be enough to keep the rain away from New Orleans.
Temperatures are likely to be in the 50s throughout the evening.
Since dry air will push across the upper Gulf coast, the corridor of showers are now likely to hover farther south.
"Enough moisture may be around to produce spotty showers over South Florida," Sosnowski said.
It will be seasonable with temperatures forecast to be in the 70s as the clock strikes midnight in Miami.

Chilly air will descend on Chicagoland ahead of the new year, but no Arctic cold is forecast.
Those watching the spectacular fireworks displays at Navy Pier or along the Chicago River will still need to pack on extra layers as temperatures will be in the upper 20s as the calendar flips to 2020. Even lower AccuWeather RealFeel® Temperatures are anticipated due to a brisk wind.
Although showers may be creeping into southern Texas on New Year's Eve, the Dallas-Fort Worth Metroplex should experience dry, cool weather for festivities throughout the area.
Temperatures are forecast to be in the 40s as fireworks fly from Reunion Tower.
"Despite rain earlier in the week, dry weather is expected for the Southwest on New Year's Eve," Anderson said.
Temperatures in Los Angeles will be seasonable, holding in the 50s through most of the evening.

Partygoers will not have to worry about rain dampening fireworks displays in Sin City.
A partly to mainly clear sky is anticipated with temperatures in the 40s. Light winds may obstruct firework viewing conditions by limiting the dissipation of smoke.
"A storm looks to make for a soggy New Year's Eve along the northern part of Interstate 5 in the Pacific Northwest, including Seattle," Anderson said.
Rounds of rain are likely to soak the Seattle area throughout the afternoon and evening hours, potentially causing the fireworks display to be canceled or postponed.
Revelers will want to bring along some rain gear and put on an extra layer or two with temperatures likely in the 40s.
