Latest Seasonal Assessment – During the past several weeks, drought coverage increased or intensified across much of the Southwest, southern Plains, and the Florida peninsula. In contrast, continued precipitation improved drought conditions across the central Appalachians and Ohio Valley, with impacts easing across West Virginia, northern Virginia, and western Maryland. Further west, precipitation ameliorated drought conditions in southern Oregon and northeastern California. With moderate to strong La Niña conditions expected to continue through the northern hemisphere winter season, strong consideration was given in this outlook to climate anomalies associated with the cold ENSO phase. Therefore, drought expansion or intensification is expected across the Gulf Coast and southern Atlantic states, particularly in Florida. To the north, storm systems frequently translate across the Ohio Valley region into New England during La Niña winters, increasing the odds for drought improvement from eastern Arkansas and western Tennessee northward into the eastern Corn Belt. A similar precipitation anomaly dipole exists across the western U.S., with increased odds for above median precipitation in the Northwest contrasting with greater chances of below median precipitation for the Southwest and southern Rockies. Due to this consideration, continued improvement is expected for remaining drought areas in northern California and western Wyoming, while drought expansion or intensification is forecasted for the desert Southwest and portions of the central and southern High Plains. Increased odds for above median precipitation during the rainy season in Hawaii favor improvement across the western islands, but significant improvement of long term drought conditions on the eastern islands is more uncertain.
