U.S. Drought Update & May Outlook: A Transition Pattern with Uneven Impacts
Recent conditions highlight a growing divide in moisture trends across the U.S.
Over the past week, a corridor from Texas through the Midwest into the Great Lakes received well above-normal precipitation — locally exceeding 300–400% of typical amounts. These rains led to targeted improvements in drought conditions, particularly across portions of Oklahoma, Texas and parts of the Midwest.
However, outside of this corridor, conditions continue to deteriorate.
Southeast: Widespread degradation persists, with expansion of severe to exceptional drought across Georgia, the Carolinas, Alabama and Florida. Agricultural impacts are becoming increasingly evident.
Central Plains & High Plains: Warm and dry conditions have supported further expansion of moderate to extreme drought, particularly in Nebraska, Kansas and eastern Colorado.
West: While precipitation was mixed, overall dryness and early snowpack melt are raising concerns about seasonal water availability.
May Outlook: Warmer Pattern with Regional Precipitation Uncertainty
Looking ahead, the May outlook points to a broadly warmer-than-normal pattern across much of the West., Great Plains and Southeast.
Temperature: The strongest probabilities for above-normal temperatures are across the Pacific Northwest and northern tier.
Precipitation: Increased chances for above-normal precipitation from Texas into the Lower Mississippi Valley. Drier tendencies favored across the Pacific Northwest and parts of the Great Basin. Much of the central and eastern U.S. remains in a section of lower predictability, typical of late spring convective patterns.
@MattMakens says he's watching large-scale drivers, including a strengthening Madden-Julian Oscillation and emerging El Niño conditions, that may contribute to variability throughout the month, particularly across the central and eastern U.S.
Matt's Key Takeaways:
While recent rainfall has provided localized drought relief, broader trends remain concerning. Drought expansion continues across key agricultural regions, and May is expected to bring a variable pattern with continued regional disparities in both temperature and precipitation.
