Alaska, Hawaii, and Puerto Rico: In Alaska, cold conditions continued, with temperatures averaging more than 10°F below normal. Dry weather prevailed, although the state’s snowpacks remained at or above seasonal norms. In Hawaii, there were no changes to the drought designation, with rain (locally up to 5 inches) mainly confined to the Big Island. There were no concerns for drought on Puerto Rico, with moderate to heavy rain (2- 6 inches) reported the island.
Looking Ahead: A series of Pacific disturbances will maintain periods of rain and high-elevation snow across the northwestern quarter of the nation, with some light to moderate precipitation also likely in the Sierra Nevada. Meanwhile, dry, warm weather will prevail from the Plains into the Southwest. However, a developing storm late in the period may provide some locally heavy rain to the nation’s mid-section, although the track, placement, and intensity of this storm system is yet to be determined. In the East, a pair of weak cold fronts will produce mostly light showers, with a swath of heavier rain possible across southern portions of the Northeast. The CPC 6-10 day forecast for April 3-7 calls for above-normal temperatures across the Rockies and Great Plains, with near- to below-normal temperatures east of the Mississippi and along the Pacific Coast. Drier-than-normal conditions are expected across much of the southern and eastern U.S., including the central Rockies and High Plains, with above-normal precipitation confined to the Pacific Northwest.
