Temperatures are going to drop to more fall-like numbers later this week as cooler air moves into the U.S. Why It Matters Extreme heat warnings and heat advisories have been in place across much of the central and southern U.S. this month, with National Weather Service (NWS) meteorologists warning of triple-digit temperatures and high humidity that can increase the risk of heat-related illness. However, millions of Americans can expect a reprieve later this week from Michigan south to Mississippi as below-average temperatures move into the region. A temperature outlook from the NWS Climate Prediction Center shows which states are expecting cooler weather in the coming days. A temperature outlook from the NWS Climate Prediction Center shows which states are expecting cooler weather in the coming days. NWS Climate Prediction Center What To Know On Tuesday, the NWS office in State College, Pennsylvania, shared a temperature outlook from the Climate Prediction Center that anticipates a drop in temperatures across much of the central and eastern U.S. later this week and into the weekend. Some states will see high temperatures drop as much as 20 degrees from where they were on Tuesday. "Following a warming trend late this week into the weekend, Autumnal air takes over the rest of the month," NWS State College posted with the temperature outlook on X. Maps shared with the post showed that the greatest chance at below-average temperatures is in the Upper Midwest from August 24-28. However, most of the U.S. has a chance at below-average temperatures for that date range, with cooler weather expected as far west as Wyoming, as far south as Mississippi and throughout the East Coast. For the South, it will be a welcome reprieve, as temperatures were around 100 degrees in Little Rock, Arkansas, on Tuesday afternoon, prompting an extreme heat warning. "Another day of dangerous heat is expected across the state with afternoon highs around 100° and heat indices even higher," NWS Little Rock posted on X. "Extreme heat warnings and heat advisories are in effect. Storms expected this afternoon, some could produce strong wind gusts and heavy downpours." However, forecasts show a high temperature of only 74 degrees in Little Rock next Tuesday. "Cooler temperatures are going to be starting to come down from the north beginning late this week, Friday starting in the Northern Plains," NWS Weather Prediction Center meteorologist Frank Pereira told Newsweek. In addition to Arkansas, parts of Nebraska and Kansas could see a 20-degree drop, as those states are currently experiencing temperatures in the mid-90s, with the mid-70s forecast for next week. What People Are Saying Wisconsin State Climatology Office, on X: "The Climate Prediction Center is forecasting high chances of cooler-than-average temperatures in Wisconsin for the end of August!" Mid-Michigan NOW, on X: "This upcoming Sunday-Tuesday will be feeling like fall with temperatures in the 60s to lower 70s! False fall for sure as readings will be back to summer-like conditions after this." WDRB Chief Meteorologist Marc Weinberg, on X: "FALL-like temperatures could be on the horizon. When we could see lows in the 50s." NWS Duluth, on X: "After warm weather this week, some fall-like weather is on the way, and it may stick around through the end of August." What Happens Next Temperatures will start to fall later this week and into the weekend. In some areas, the cooler weather is expected to persist through the end of August.

La Niña is declared over. Here's what that means for New England weather.
El Niño and La Niña are the warm and cool phases of a naturally occurring climate pattern across the tropical eastern Pacific Ocean, off the west South American coast, that oscillates back and forth every two to seven years, greatly influencing and disrupting the weather across the U.S. and worldwide. They also cause predictable shifts in ocean surface temperature. Tropical meteorologists will rely heavily on sea surface temperatures when it comes to storm forecasting. A La Niña typically leads to a more active hurricane season while El Niño is a suppressor. Advertisement Colorado State University has released their seasonal forecast already, with a relatively more active season than typical, but not as strong as what we saw last year. Last season produced 18 named storms with 11 hurricanes while experts from CSU suggest 17 named storms with 9 hurricanes — mainly because sea surface temperature are still running notably above the climatological norm. Advertisement La Niña is marked by cooler than average temperatures from strong equatorial trade winds in the equatorial Pacific Ocean off the South American coast. The event came to life over during the start of winter and stayed very weak over the last few months. — NWS Climate Prediction Center (@NWSCPC) We have to remember that regardless of neutral conditions, the atmosphere and ocean are still rising, which provides the fuel for extreme storms to continue to develop over the country and the Atlantic basin.
