Drought conditions have been elevated locally

In the latest update from the U. S. Drought Monitor (USDM), all of Allegany, Steuben, Livingston and Wyoming counties have been elevated to a "severe" drought stage. The northern and northeastern part of Cattaraugus has also been elevated to a "severe" stage.
In Pennsylvania, half of Potter County is now listed under the "severe" stage while McKean County is classified as "abnormally dry."
Another mostly below normal precipitation week in the Northeast as only light rain fell later in the USDM period. Convection affected areas which have been wetter rather than the drier areas. The driest areas were concentrated in western New York and Pennsylvania, and much of Massachusetts, Connecticut, and Rhode Island. For the last 30 days, precipitation is below 25 percent of normal. Stream flows at all levels (1-, 7-, 14-, and 28-day) are reaching into the tenth percentiles. Moderate to Severe drought (D1-D2) was expanded to cover these high impact areas. Media reports of problems due to the dry weather are becoming common in the region and New York issued the first statewide drought watch since 2002. Massachusetts was also issued a drought watch.
