East Remains Dry, While Louisiana Receives Unwanted Rain09/01/2016
This U.S. Drought Monitor week saw a swath of above normal precipitation stretching from western Texas northeastward through parts of western Oklahoma, much of Kansas, northwest Missouri and into northern Illinois.
A combination of moisture flowing in from the Southwest and Southeast along with a stalled frontal boundary brought abundant precipitation to areas of Texas and New Mexico. The heaviest rains during the period fell in western Texas and southeast New Mexico where at least 5 inches were measured. Approximately 5 inches of rain also fell in northwest Missouri and northeast Iowa.
Elsewhere high pressure remained in control along the east and southeast coast line limiting precipitation to nothing more than typical summer time convection, resulting in drier than normal conditions all along the Eastern seaboard.
Louisiana continued to experience wetter than normal conditions, further pushing their statewide precipitation total to a possible record amount for August. Virtually no precipitation was observed west of the Rockies.
Temperatures for the period ranged from 6-8 degrees below average in the Four Corners region to 6-8 degrees above average in eastern Ohio. Generally speaking, above average temperatures were observed in the eastern half of the Country along with the Northwest, while below average temperatures occurred in the Northern Plains and south into the Southwest and Texas.
According to the Climate Prediction Center (CPC), the heaviest precipitation will fall along the coast of Florida and the Carolinas over the course of the next 24-48 hours. This is associated with Tropical Storm Hermine. As the Tropical Storm moves along the eastern seaboard, it is forecast to leave several inches of rain in its wake.
During the next 5 days, precipitation is expected to be in the 1-2 inch category across the New Mexico and Texas border region stretching north and eastward into Oklahoma and into the Dakotas.
Maximum temperatures during the next 3-5 days will be in the 90’s across much of the southern plains and Tennessee valley, while mid-60’s will be seen in the High Plains. According to the CPC, chances are greater than normal to have above average temperatures in the eastern half of the country while the High Plains may experience below average temperatures. During the same period odds are in favor for above average precipitation to fall in the Great Lakes region. Below average precipitation is expected in the Southwest and much of the East Coast.
Looking further out at 8-14 days, odds are favorable that above average temperatures will occur in Northeast while the High Plains continues to be below normal. Precipitation during the period is likely to be below normal in portions of the Southeast, but above normal for the Midwest.
