358 Tornado Warnings Issued Across the Midwest This Month While Alabama and Deep South Stay Calm but Active Pattern Change Expected Late April Into May
ALABAMA AND DEEP SOUTH — Alabama and the Deep South have experienced a remarkably calm April so far as an upper ridge has kept severe storms and tornadoes well to the north and west. However, that calm period is not expected to last, with global models consistently signaling a pattern change that will bring active weather back into the region later this month and into at least the first part of May. Alabama’s tornado season runs through the end of May, meaning the most significant threats for the state may still lie ahead.
358 Tornado Warnings Issued Across the Midwest This Month
While Alabama has stayed quiet, the Midwest and central United States have absorbed a staggering 358 tornado warnings so far this month. The tornado warning map shows a dense concentration of red warning polygons blanketing the upper Midwest, Great Lakes, and central Plains corridor, with particularly heavy warning activity across Iowa, Wisconsin, Illinois, Indiana, Michigan, and Missouri.
The contrast between the warning-free Deep South and the warning-saturated Midwest visually captures just how effectively the upper ridge has shielded Alabama and surrounding states from the severe weather pattern dominating the rest of the country throughout April.
Upper Ridge Has Protected Alabama But Won’t Last
The atmospheric upper ridge responsible for keeping Alabama calm is expected to break down as the month progresses. Global models are consistently showing this pattern change bringing active and potentially significant severe weather back into the Deep South region later this month and continuing into early May.
When the ridge finally retreats, the Deep South will lose its protective barrier and become exposed to the same type of active severe weather pattern that has produced the extraordinary tornado warning totals across the Midwest throughout April.
Probability Maps Show Increasing Severe Weather Risk Ahead
The extended outlook probability map shows a broad swath of elevated severe weather probability developing across the central and southern United States in the coming weeks. The highest probabilities shown in orange and red are centered across Oklahoma, Kansas, Arkansas, and surrounding areas, with meaningful probabilities extending eastward into Alabama, Tennessee, Mississippi, and the broader Deep South region.
The blue probability zone extends across an enormous geographic footprint from the Plains all the way through the Tennessee Valley and into the Southeast, confirming model agreement on the upcoming pattern change.
Alabama Tornado Season Continues Through End of May
With Alabama’s tornado season running through the end of May, residents across the state should not interpret the calm April as a signal that severe weather risk has passed for the year. The most impactful tornado events in Alabama history have occurred at various points throughout the spring season, and the approaching pattern change means the remainder of April and early May demand continued vigilance and preparedness across the state.
