South: Rain amounts for this week combined with high temperatures and long term precipitation deficits added additional stress to the water systems in parts of the Texas Panhandle, leading to the expansion of extreme and exceptional drought conditions. Moderate to heavy rain over the Interstate 35 corridor in Oklahoma and in north-central to west Texas allowed for 1-category improvements in some areas that were experiencing abnormal dryness, moderate drought, severe drought, and extreme drought. Meanwhile, continued dry and hot conditions led to the introduction of extreme drought west of Lubbock and in areas near Corpus Christi where soil moisture deficits and mid to long term precipitation deficits supported degradation. Additionally, extreme drought was expanded in the Del Rio area northeast of the Rio Grande and in a corridor north of Houston and College Station in response to building precipitation deficits in these areas. The drought impact designation in far south Texas was changed from S to SL, indicating that drought conditions are present at both short and long term timescales. Elsewhere in the South, a few areas of abnormal dryness and moderate drought formed or expanded in Louisiana, Mississippi, Arkansas, and eastern Oklahoma that missed out on the moderate to heavy rains in the region.
Looking Ahead: The National Weather Service medium range forecast calls for two significant areas of wet weather over the next 7 days (June 13 to June 20). Widespread and potentially heavy rainfall is expected to bring 2 to 5 inches of rain to coastal and central Texas and southern Louisiana. Rainfall may also extend into the Southern Plains and the remainder of the Gulf Coast region.
Farther north, showers and thunderstorms are likely from the Northern Rockies to the High Plains and Upper Great Lakes. Rainfall over the northern tier is likely to be locally heavy (3 to 5 inches) creating the potential for isolated flooding. In contrast, dry weather is expected to prevail over the Pacific Coast and the drought inflicted areas of southern California, southern Nevada, and western Utah.
