Fall is definitely a season of change and the change is becoming apparent.
Right after experiencing the record breaking hottest temperatures, USA is now in for a plunge of chilly air.
Changes in the wind are starkly visible as an upper-atmospheric trough is carving southward into the East and Midwest as against a ridge earlier.
This past Sunday, Caribou, Maine basked in 84-degree warmth, the hottest temperature on record so late in the season, there. Daily record highs were also set Sunday in at least a dozen other northern cities, including Newark (87), Providence (86), Sault Ste. Marie (80) and Duluth (81).
This change in pattern has brought the temperatures that are 20-30 degrees colder for some locations in the northern Plains. Temperatures will also be cooler in parts of the Midwest and Northeast, where maximum temperatures are expected to come down from the 70s to 50s.
Due to this fresh onset of cold air, the weekend is expected to be fairly pleasant. Low temperatures will even drop into the 30s and 40s for much of the Southeast by Sunday morning.
As temperatures cool down in the East, the warmth has made a comeback along the West Coast. Los Angeles witnessed maximum temperature in the 90s all the way to the beaches on October 3 and 4. Maximum temperature in San Francisco Bay area also surged into 90s to near 100.
