Cooler May Forecasted Across Eastern U.S., Warmer in the West
Forecasters predict a cooler-than-normal May for much of the eastern United States, with the Midwest experiencing the most significant drop in temperatures. According to the Climate Prediction Center's meteorologist Brad Pugh, overnight lows in the Midwest could reach freezing levels. AccuWeather's Paul Pastelok notes that the eastern half of the country will feel more like early spring, with frequent cloud cover. In contrast, the West Coast, particularly the Pacific Northwest, is expected to experience above-average temperatures, transitioning to summer-like conditions faster than the rest of the country. This pattern is attributed to a dip in the jet stream over the U.S., which is expected to shift by the third week of May, allowing warmer air to move in.
