Drought

Though it is miserably hot, humid, and dry in South Arkansas now, the accompanying map of the state shows only a very small area of one county in distress, according to the United States Drought Monitor map released August 15.

This shows a small corner of Little River County as being considered "abnormally dry."

As of August 20, the Arkansas Forestry Commission showed all 75 Arkansas counties in "low danger" status for wildfires. There were no burn bans showing as of August 20.

The National Weather Service Office in Shreveport, La., is predicting a 30 percent chance of showers and thunderstorms on Thursday, a 40 percent chance on Friday, and a 50 percent chance on Saturday.

In the southern part of the United States, no measurable rain fell on a large area from the Red River Valley southward through Texas east of the Big Bend, extending eastward into southwestern Arkansas and central Louisiana. In contrast, most of northeastern Oklahoma and northern Arkansas were doused by 2 to locally 6 inches of rain. Less remarkable rainfall amounts exceeding one-half inch were recorded in the Texas Panhandle, central and northern Oklahoma, southwestern Tennessee, and Mississippi, with heavy rains approaching 4 inches reported in a few scattered areas.

Dryness and drought expanded and intensified, with some degree of dryness now covering northeastern Texas, part of northern Louisiana, central and western Oklahoma, and roughly the western two-thirds of Texas from the upper reaches of Deep South Texas northward to the central Panhandle and the Big Bend. Severe drought was noted in parts of southern Texas, west-central Texas, and in a strip from southwestern Oklahoma westward along the southern fringes of the Texas Panhandle.

Parts of these D2 areas received 3 to 6 inches less rainfall than normal over the past 60 days, including most of southwestern Oklahoma and adjacent Texas.

Dating back to mid-July, most of Oklahoma (outside the northeastern quarter) and Texas were at least an inch short of normal rainfall; 30-day rainfall totals below 0.5 inch fell on southwestern Oklahoma and a broad swath of central and southern Texas from the Red River and lower Panhandle southward to the lower Rio Grande Valley.

Showers and thunderstorms were hit-and-miss across the southeast region of the United States, but only a few tenths of an inch of rain fell on most of the Carolinas (away from the immediate coast), central and northern Georgia, and the eastern half of Alabama. Rainfall was a little more abundant in western Alabama, Florida, and especially southeastern Georgia. At least a few tenths of an inch fell, and amounts of 1.5 to locally 3.5 inches covered nearly half of these areas. The heavier totals (over 1.5 inches) were more widespread in southeastern Georgia, with 4 to nearly 6 inches soaking a few patches near the Florida border.

Dryness and drought improvement were noted in a few small areas where rainfall was heavier, but deterioration was much more common, especially from eastern Alabama through southeastern North Carolina. Most notably, abnormal dryness expanded broadly to cover most of central Georgia and South Carolina. Rainfall deficits of 6 to 9 inches since mid-May were observed in parts of southeastern Alabama and southeastern

North Carolina while amounts 3 to 6 inches below normal covered central and southwestern Georgia and a few areas of non-coastal South Carolina.

Abnormal dryness continued the recent trend of expansion in the Midwest, and a few areas of moderate drought were introduced. Several patches were brought in to central and eastern Iowa, and adjacent Illinois, along with smaller, more-isolated regions in eastern Illinois and northern Indiana. Meanwhile, abnormal dryness stretched to cover most areas from central Iowa eastward to central Indiana and southwestern Michigan, plus portions of southwestern Ohio, southern Indiana and adjacent Kentucky, sections of northern and eastern Michigan, and northeastern Minnesota.

The last 30 days brought only 0.5 to 2.0 inches of rain to the broad strip from central Iowa through western Indiana, in addition to east-central Michigan and the eastern half of the Upper Peninsula.

In the High Plains area, several inches of rain doused a broad area from eastern Kansas northwestward through South Dakota, western North Dakota, and the northern High Plains. Dryness and drought were confined to central and southern Kansas, east-central Nebraska, and northern North Dakota, where a small area of severe drought was introduced. In contrast to areas farther north, central and south-central Kansas recorded only 0.5 to locally 2.0 inches of rain since mid-July.

For the western part of the country, periodic light to moderate rain has fallen for a few weeks now from central and southern Washington eastward through southwestern Montana, prompting improvement in some former D0 to D1 regions there, and in adjacent Oregon. Farther south, abnormal dryness persisted in several areas from southwestern Wyoming through Utah and western Colorado; D0 expanded northward a bit into areas north of the Four Corners near the Colorado/Utah border.

Across the southern Rockies and southwestern deserts, deficient monsoon rains continued, and increasing moisture deficits prompted a broad expansion of abnormal dryness from southeasternmost California through eastern Arizona, and farther south from southeastern Arizona across southern New Mexico.

For Alaska, Hawaii, and Puerto Rico, heavy precipitation and cooler temperatures brought continued relief to much of Alaska. Abnormal dryness remained in the Yukon Flats, but all other dry areas across the interior were removed. In contrast,

beneficial precipitation evaded much of southern Alaska for the second consecutive week. And abnormal dryness or drought still covers areas from interior southwestern Alaska through the southeastern Panhandle.

South-central Alaska has been particularly parched recently. The last 3 months brought record to near-record low rainfall totals to part of the region, thus severe drought (D2) was introduced there.

A fairly typical summer week of scattered rainfall affected Puerto Rico. Dryness and drought essentially persisted, except for areas that missed much of the rain over the last few weeks. D2 was expanded eastward in south-central Puerto Rico, and the eastern D0 boundary was pushed eastward in eastern parts of the Commonwealth.

An unremarkable week of typical summer weather was also observed across Hawaii, leaving areas of dryness and drought unchanged.

During the next 5 days (August 15 - 20, 2019) should bring heavy rains of at least 1.5 inches across the central Great Plains and much of the Midwest, with 3 to 5 inches forecast from northwestern Missouri and adjacent areas northward through

central and eastern Iowa. Amounts exceeding 1.5 inches are also forecast for the Mississippi Delta and along the immediate Gulf and southern Atlantic Coasts.

A few patches along the Atlantic Coast from southeastern Georgia through North Carolina should receive 3 to 4 inches.

Moderate rains of 0.5 inch or more are anticipated in parts of upstate New York, northern New England, and inland areas near the central Gulf and southern Atlantic Coasts. Similar amounts are expected in most of the western Great Lakes, Midwest, Great Plains from Kansas into the central Dakotas, and upper Mississippi Valley.

A few tenths of an inch should fall on the middle Atlantic region, the rest of the central and northern Great Plains and Mississippi Valley, and parts of central and northern Texas and adjacent Oklahoma.

Little or no rain is expected in the rest of the 48 contiguous states, including the interior Southeast, the Ohio Valley, southern Texas, and most areas from the Rockies westward. Daytime high temperatures should average 3°F to 6°F below normal in the northern one-third of the Plains, and near 3°F below normal in north-central Florida.

In contrast, daily highs are forecast to average around 3°F above normal in the middle Atlantic region, and 3°F to locally 9°F above normal from the southern half of the Great Plains westward through most of the Rockies, the Intermountain West, the Great Basin, and California away from the immediate coast.
