Drought conditions are slowly developing in a small portion of the Mid-Atlantic region, especially in central Pennsylvania.

Note: If there are areas in yellow, then these areas are experiencing abnormally dry, but not quite drought, conditions.  See below for additional drought related links.

The outlook for water resources and supplies is good for most of the Middle Atlantic Region.  However, parts of the region from central Pennsylvania northward are experiencing fair conditions as a result of dry weather over the past several months. 

 

Rainfall has been sufficient or abundant for eastern and southern parts of the Mid-Atlantic.  This is not the case everywhere, however, especially for south-central New York as well as north-central and central Pennsylvania where a lack of rainfall has led to drought conditions.  The state of Pennsylvania has issued some drought watches and a warning for this region:

https://www.dep.pa.gov/Business/Water/PlanningConservation/Drought/Pages/default.aspx

 

The Mid-Atlantic remains fairly wet for eastern and southern areas.  But, central Pennsylvania and points northward remain dry.  Also, dry conditions have been spreading eastward and southward from this region, especially the past several weeks.  Water supply and water resources are good for most of the Mid-Atlantic.  The exception is central Pennsylvania northward where conditions are fair.

 

The U.S. Drought Monitor ( https://droughtmonitor.unl.edu/data/png/current/current_rfcMARFC_trd.png  ) indicates that parts of central Pennsylvania and points north are in some level of drought.  Check back weekly (Thursdays) to the Drought Monitor to see how conditions are changing.  Right now, the situation is unlikely to spread much or get worse, mainly because autumn has begun and the spread of drought is typically a decreasing problem.
