Even if this weekend's publicized and well-hyped rains do end up materializing, they will help dampen but not eliminate the growing dry island known as the East Coast. Much of the Northeast and Mid Atlantic are increasing in dryness and the level of drought based on the NOAA/University of Nebraska Drought Monitor is increasing as well.
The current drought monitor maps were issued this morning, showing 60% of Pennsylvania in some stage of abnormally dry conditions...up from 48% last week. New Jersey and Delaware saw no change in their dry island status from last week to this as both states are in some stage of drought -- whether it be classified as moderate (New Jersey) or severe (southern 78% of Delaware).
Steady rains will help limit the status of drought and knock the dryness back a notch, especially in Delaware. However, if the potential trend of a New England hit and a local miss from this weekend's storm system ends up materializing, the dry trend will continue.
