The latest weather outlook for the months of August through October reveals a significant temperature contrast across the United States. While the Great Lakes are expected to experience cooler conditions, the Western region is forecasted to be warmer, particularly as summer transitions into fall.

According to the outlook released by Atmospheric G2 and The Weather Company, August is anticipated to be warmer than average for much of the Eastern U.S., stretching from Florida to New England. However, the Great Lakes and parts of the Midwest, especially northern Michigan and northern Wisconsin, are expected to remain cooler than average.

As September approaches, temperatures may rise above average across much of the nation. Interestingly, the South could see a cooler than average October, which could provide a refreshing change after the summer heat.

One of the key factors influencing this weather pattern is the intensifying El Niño, which is currently stronger than previous strong El Niños observed through mid-July. Todd Crawford, Vice President of Meteorology at Atmospheric G2, noted that computer models are predicting an increase in the strength of this potential record-setting El Niño into the fall and winter months. This phenomenon is expected to play a significant role in shaping the temperature outlook for October.

Historically, stronger El Niño events have led to cooler conditions in parts of the East during October, and current model forecasts suggest that the fall may trend cooler in various areas of the South and Southeast.

Additionally, the outlook indicates that the Southwest monsoon season, which typically features summer thunderstorms, is expected to be wetter than usual through September. Conversely, the Pacific Northwest is likely to experience a notably dry period over the next three months, which is unusual for this time of year.

Overall, the August through October outlook suggests a dynamic weather pattern influenced by both El Niño and regional climatic conditions, leading to varied temperatures across the United States.
