Hawaii, Alaska and Puerto Rico: Currently, there is neither dryness nor drought depicted in Alaska and Puerto. Meanwhile, windy but otherwise mostly uneventful weather covered Hawaii, resulting in minimal change in the drought depiction. Although Hawaiian showers were generally light and confined to windward locations, strong trade winds buffeted the islands. On Maui, Kahului clocked wind gusts above 40 mph on eight consecutive days from May 22-29.
Looking Ahead: During the next 5 days (May 31 – June 4), a developing storm currently over the south-central U.S. will drift northeastward to a position north of the Great Lakes during the weekend. Storm-total rainfall could reach 1 to 3 inches, with locally higher amounts, from the central and southern Plains into the Northeast. Meanwhile, building heat across the West will shift into the nation’s mid-section by early next week. The Midwest, South, and East will experience a significant break from the heat that peaked during the Memorial Day weekend.
The NWS 6- to 10-day outlook for June 5-9 calls for above-normal temperatures and below-normal rainfall across the majority of the U.S. Cooler-than-normal conditions will be confined to the middle and northern Atlantic States and areas along the Pacific Coast, while wetter-than-normal weather will be limited to the Mid-Atlantic coast and across the nation’s northern tier from the Pacific Northwest to the Red River Valley.
