Weather Summary: In what has become a familiar pattern, heavy precipitation continued to improve drought and dryness across the northern half of the West Coast States, though it created its own set of significant impacts. Farther south, similar totals fell on a relatively small area in southwest California. Heavy precipitation – some falling as heavy snow – also covered areas from the Ohio Valley and Middle Atlantic States southward through the Tennessee Valley, the interior Southeast, and the Carolinas. Parts of the Rockies – primarily the higher elevations – also reported moderate to heavy precipitation. Meanwhile, only light precipitation fell on the Northeast, across much of the lower Midwest, and along most of the Gulf Coast and adjacent areas. Most of the Plains and upper Mississippi Valley reported little or no precipitation. The result was some significant areas of drought improvement across the Carolinas and interior Southeast, as well as parts of the West Coast States and Rockies. In contrast, unseasonably warm and dry weather for several weeks prompted fairly broad areas of deterioration along the immediate central Gulf Coast, the southwestern half of the lower Mississippi Valley, and the southern Plains.
