It was a mixed picture for the dry areas across the country. Widespread rainfall totals exceeding 2 inches fell from northeast Montana to north-central North Dakota, with a swath of 4 to 6 inches soaking part of northwest North Dakota. Farther east, generally under an inch fell on northeastern North Dakota and northern Minnesota near the Canadian border, with amounts increasing to the south. Between 0.5 and 2.0 inches of rain fell on the climatologically-wetter areas of the Pacific Northwest on the west side of the Cascades and along the immediate coast, and 0.5 to 1.0 inch fell on northwestern Montana and part of adjacent Idaho. Other parts of the Northwest recorded less than 0.5 inch, with only a few tenths of an inch falling on most of interior Washington and Oregon. Very little, if any, precipitation fell farther to the south, from central Oregon and Idaho southward through the Far West, and roughly the western half of the Four Corners region. Rainfall was highly variable through south Texas and the Southeast (not uncommon during summer). Several small areas from south Georgia, north Florida, and Alabama westward received over 2 inches of rain, with isolated amounts reaching nearly 6 inches in south Texas. Rainfall was considerably sparser from central and north Georgia through the Carolinas, where most sites recorded only a few tenths of an inch. Outside the contiguous states, light to moderate rains fell on north-central and central Puerto Rico while little or none was observed along the southern tier of the Commonwealth. Historically heavy out-of-season rains soaked parts of the leeward areas across Hawaii, with over 4 inches soaking Honolulu within 24 hours – more than any prior full month of June on record brought.
Some short-term precipitation shortfalls have popped up across interior southern New England and a few other isolated areas, but D0 introduction was not warranted at this time, and the region remains free of any dryness on the Drought Monitor.
The rainfall pattern was highly variable across the region. Amounts of 0.5 to 2.0 inches (and locally greater) were common across south Georgia, north Florida, and the west half of Alabama, but only scattered to isolated areas across southeast Louisiana, north and central Georgia, and most of the Carolinas received as much. The broken rainfall pattern resulted in numerous small tweaks across the region, but larger changes included the removal of D0 through significant swaths of southern South Carolina and central Georgia (based on a re-assessment of effects from last week’s heavy rain), and some westward and southward expansion of the moderate drought near the coast of the central Carolinas.
Light to isolated moderate rainfall kept D0 essentially unchanged in western Tennessee. Farther south, an area of 2 or more inches of rain eliminated the D0 near south-central Louisiana, but lighter rains to the east kept abnormal dryness in other parts of southeast Louisiana. Across central Texas, rainfall was sparse, and several small areas of D0 there. In south Texas, where more marked dryness existed, a small swath of heavy rain (up to 6 inches) eliminated severe drought across interior areas, and ended the moderate drought farther north toward Laredo. In contrast, lesser rains allowed severe drought to develop in a small area of far southwest Texas, and kept dry conditions generally unchanged in the rest of south Texas.
Another week of heavy rainfall affected areas from Wisconsin and north Iowa northward through most of Minnesota, but precipitation was again sparse along the northern tier of that state, allowing moisture deficits to increase and prompting the extension of D0 eastward along the Canadian border. A broken pattern of moderate to heavy rain fell on a swath across Illinois and adjacent areas to the east and west while much of Iowa, Missouri, central and east Indiana, and most of Ohio and Kentucky were drier. No abnormal dryness was identified anywhere outside the north tier of Minnesota.
Another wet week was observed across northwest North Dakota, with amounts of 4 to locally over 6 inches soaking a swath just south of the Canadian border. This resulted in the removal of D0 from much of the area. Conditions were considerably drier farther to the east, keeping D0 to D2 intact over central and eastern parts of North Dakota, and allowing for some southward and eastward D0 expansion in northeastern North Dakota toward Minnesota. Copious rainfall was measured in central parts of the region, but only a few patches across Colorado and Kansas received over 0.5 inch. No dryness or drought was noted south of central North Dakota.
