Drought Monitor: Precip Deficits Remain Large in Southern Plains

October 27, 2011 02:54 AM

According to this week's National Drought Monitor, this week saw mostly dry weather in the southern and central High Plains and near to above-normal temps. While some rains were seen, it's going to take a lot more to lift the region out of the long-lasting drought.


The Drought Monitor notes the Central and Southern Plains has entered a time period that usually does not feature meaningful rains. "As a result, it is uncommon that widespread, precipitation-drenching storms would occur and alleviate any drought conditions. With that said, however, any precipitation deficits that would accumulate during dry periods would be small, and temperatures and evaporation would typically be much lower than the summer," it says.

Meanwhile in the Midwest, rains helped to ease drought in some eastern areas, while less beneficial rains were seen in the western drought area of the region.

Looking ahead, the monitor says during the next 5 days (October 20-24), relatively tranquil weather will envelop most of the lower 48 States once the current storm systems in the Midwest and Northeast move out by early Friday. Expect the largest totals (1 to 3 inches) in the northeastern quarter of the U.S., especially Michigan and coastal New England. 5-day temperatures should be above-normal in the western half of the Nation and in northern New England, while subnormal readings cover the Midwest, mid-Atlantic, and Southeast.

The CPC 6-10 day outlook (October 25-29) calls for an amplified ridge over the West Coast with a trough over the East. This translates to favorable odds of above-normal precipitation in the Northeast, southern Florida, and the central Rockies, with subnormal precipitation in the West, the Great Plains, and across the southern tier of States. Above-normal temperatures are forecast for the Far West, with subnormal readings predicted for much of the Nation east of the Rockies, especially in the South.
