This Week’s Drought Summary

A stationary front was a focus for frequent showers and thunderstorms with locally heavy rainfall from eastern South Carolina south to the Big Bend of Florida from June 11 to 14. The heavier rainfall resulted in short-term rainfall surpluses and drought elimination to parts of the Coastal Plain of Georgia and South Carolina. Another cold front progressed slowly south and east across the Great Plains, Corn Belt, and Mississippi Valley from June 14 to 16 before becoming stationary. Locally heavy rain (more than 2 inches) and hundreds of severe weather reports were common across the central and southern Great Plains, middle to upper Mississippi Valley, and Ohio Valley during mid-June. Excessively wet conditions continue to slow the emergence of corn and soybeans across the Corn Belt. Meanwhile, drought intensified across northern North Dakota due to a lack of rainfall since April. A strong ridge of high pressure resulted in dry weather and record high temperatures (June 11 and 12) across the Pacific Northwest where drought is also intensifying. Suppressed rainfall continues to affect parts of Puerto Rico…

High Plains

Late May through mid-June is typically a wetter time of year across the northern Great Plains. However, during the past 60 days, parts of northwest North Dakota have received less than 50 percent of their normal rainfall. Given the lack of rainfall since the snow melt in early April, multiple adverse impacts to agriculture and livestock are being reported across the northern tier of counties in North Dakota. These reports include: lack of forage production on pastures, culling of cattle herds, and delayed crop growth. Based on the increasing short-term deficits, soil moisture conditions, and reported impacts, severe drought (D2) is warranted for parts of northern North Dakota. A lack of late spring rainfall also continues to result in an expansion of abnormal dryness (D0) and moderate drought (D1) across the northern half of North Dakota. In contrast to the worsening conditions across North Dakota, abnormal dryness was removed from the Big Horn Mountains of Wyoming based on a continuation of a favorably wet pattern through May and June…

West

The month of May tied for the 9th warmest for Washington dating back to 1895 and statewide March thru May tied for the 13th driest period on record Based on 90-day precipitation deficits of more than 8 inches along with 28-day streamflows and soil moisture below the 10th percentile, severe drought (D2) was expanded across western Washington. Levels along Rimrock Lake are extremely low with adverse impacts to boating docks. Record high temperatures during early June also played a role in the intensification of drought across western parts of Washington and Oregon. On June 12, a daily-record high of 95 degrees F was set in Seattle. In Oregon, daily-record highs on June 12 included: 98F at Portland, 99F at Medford, and 101F at Roseburg. The expansion this week of D0 and D1 across Oregon and Washington is generally reflective of the current 28-day streamflows. Long-term D0 remains in parts of southern California due to the multi-year drought. Elsewhere across California and the Great Basin, many reservoirs are full and 28-day streamflows remain high after the onset of the snowmelt season…

South

7-day rainfall anomalies (June 11 to 17) varied across the southern Great Plains, lower Mississippi Valley, and Tennessee Valley which is typical for this time of year. The heaviest rainfall (2 to 4 inches, locally more) was observed across scattered areas of Oklahoma, eastern Texas, and the Texas Gulf Coast. Less than an inch of rainfall was generally observed across most of Arkansas and adjacent areas of northwest Mississippi and western Tennessee. The Vegetation Drought Response Index (VegDRI) continues to reflect moist conditions throughout much of this region. Soil moisture remains above the 99th percentile across most of Oklahoma and northern Texas. According to the Oklahoma Mesonet, the northeast quarter of Oklahoma has received 12 to 18 inches of rainfall during the past 30 days. Abnormal dryness was expanded slightly across parts of the Tennessee Valley in areas where 60-day precipitation averages 50 to 75 percent of normal. However, much of this region remains drought-free since 28-day streamflows and soil moisture do not support a drought designation at this time. A slight expansion of abnormal dryness (D0) and moderate drought (D1) was necessary across Deep South Texas due to increasing short-term rainfall deficits and periods of above normal temperatures during the past month…

Looking Ahead

During the next 5 days (June 20-24, 2019), a couple of cold fronts are forecast to progress east across the northern half of the central and eastern U.S. On June 20, locally heavy rain (more than 1 inch) is expected to accompany a cold front as it crosses the Northeast and northern mid-Atlantic. A second frontal system is likely to trigger severe thunderstorms with heavy rainfall across the central U.S. The NWS WPC 5-day quantitative precipitation forecast (QPF) calls for widespread amounts of 1 to 3 inches, locally more, from eastern portions of the central and southern Great Plains east to the Midwest and Ohio Valley. Dry weather is likely to persist across southern Texas and the Pacific Northwest. The most anomalous warmth is expected across the Gulf Coast States. Overall suppressed rainfall is expected to continue for Puerto Rico through late June.

The CPC 6-10 day outlook (June 25-29, 2019) favors above-normal temperatures across much of the central and eastern U.S. with below-normal temperatures lingering over the western U.S. Enhanced odds for above-normal precipitation are forecast for much of the eastern U.S., Ohio and Tennessee Valleys, middle to lower Mississippi Valley, and southern Great Plains. A slight tilt in the odds for below-normal precipitation is forecast for southern areas of Florida and Texas, the High Plains, and central to southern Rockies. A relatively warm and dry pattern is most likely to persist across Alaska.
