South: Gulf rains also provided relief across southeastern Texas, while heavy Day7 rains (3-8 inches) between Laredo and San Antonio fell on a large D2-D3 area, putting a substantial dent into the drought. North-south bands of scattered showers were observed in portions of central and northeastern Texas, slightly decreasing the D2 and D3areas. In western Texas, a calibration between the radar-based precipitation totals (AHPS) versus gauge-based (ACIS) and other indices showed a wet bias in the radar-based precipitation, thus some additional deterioration was shown in this region, with more areas of D2 and D3 depicted. A spot of D4 was added near Amarillo. In addition, the fifth warmest summer on record for Texas exacerbated the dryness. In Oklahoma, spotty rains (1-2 inches) eased drought in the extreme western Panhandle, and in southwestern and northeastern sections.
Looking Ahead: For the ensuing 5 days (Sept. 6-10), heavy rain is expected from the southern Plains northeastward into the mid-Atlantic, with the Midwest drought area once again targeted for additional copious rainfall. Most of Texas and Oklahoma should also see substantial totals, as should the Ohio Valley and mid-Atlantic. Moisture from the remnants of Tropical Storm Gordon will contribute to some of these large precipitation amounts. Most of the West, northern Rockies and Plains, parts of the interior Southeast, and coastal New England are forecast to get little or no rain. 5-day temperatures should average below-normal in the Nation’s midsection where the rain is expected, while above-normal readings return to the West.
For the CPC 6-10 day extended range outlook (Sep. 11-15), the odds favor above normal precipitation along the Gulf and Atlantic Coast States, the Pacific Northwest, northern Plains, and upper Midwest. In contrast, subnormal rainfall is likely in the central U.S. and western Great Lakes region which should be welcome after heavy rains that have fallen and are expect to occur in the next 5 days. The southern half of Alaska is favored for subnormal precipitation. Most of the Nation from the Rockies eastward (and Alaska) should see above-normal temperature, with odds for subnormal readings limited to the Northwest, Texas, and eastern Alaska.
