As spring approaches, varied weather patterns are expected to impact different regions across the United States. The Old Farmers' Almanac anticipates a warm spring season, highlighting significant differences in temperature and precipitation. In the Deep South, residents should brace for a wetter-than-usual spring with an increased frequency of thunderstorms. Meanwhile, certain regions will experience dry spells, including upper New England, southern Florida, and parts of the Midwest.
Weather experts attribute these variations to multiple factors influencing the spring forecast. Among them, solar activity and equatorial stratospheric winds, specifically the Quasi-Biennial Oscillation (QBO), are areas of particular interest.
"We’re also watching solar activity and equatorial stratospheric winds known as the Quasi-Biennial Oscillation (QBO),"
In April, those in nearby regions might encounter chillier temperatures than usual, while May promises abundant sunlight and warmth. A weak La Nina phase is also on the horizon, characterized by cooler-than-average ocean surface temperatures. As for solar activity, Solar Cycle 25 is expected to peak around July 2025, having already surpassed the peak of Solar Cycle 24.
"High solar activity levels have historically been linked to warmer temperatures, on average, across Earth, although this relationship has become weaker in recent decades,"
The connection between solar activity and global temperatures, though historically significant, has shown signs of weakening in recent decades. High solar activity has often been associated with warmer temperatures, but its influence today appears more nuanced.
Severe weather threats remain a concern, particularly in the Deep South, where wind, hail, and tornadoes could pose significant risks. On the other hand, regions such as the Lower Great Lakes may witness winter’s final hurrah with late-season snowfalls potentially extending into April.
In contrast, areas including Texas, Oklahoma, the western Ohio Valley, the Pacific Northwest, northern California, and the Heartlands might see dry periods throughout the spring season. These dry bouts could affect agricultural activities and water resources in these regions.
