DESCRIPTION: There is an elevated risk for fire spread through early this evening across most of New Jersey and Southeastern Pennsylvania. Minimum relative humidity values will drop to 15 and 30 percent. This will be accompanied by northwesterly winds of 10 to 15 mph with gusts up to 25 mph. These conditions, along with the continued drying of fine fuels, could support the rapid spread of any fires that ignite, which could quickly become difficult to control. The winds will diminish later this evening and the relative humidity will also increase. Outdoor burning is strongly discouraged. Be sure to properly extinguish or dispose of any potential ignition sources, including smoking materials such as cigarette butts. This forecast considers meteorological, fuel, and land conditions and has been developed in coordination with state fire officials.

A hole punch cloud is an unusual occurrence when a disk-shaped
hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.
When part of the cloud forms ice crystals, water droplets in the surrounding area
of the cloud evaporate. The effect of this process produces a large elliptical
gap in the cloud. The hole punch cloud formation is rare, but it is not specific
to any geographic area.
Other names which have been used to describe this phenomena include fallstreak hole,
skypunch, and cloud hole.

A nimbostratus cloud is similar to a stratus cloud in its formless,
smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud,
because it is thicker.
Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat
of moderate to heavy precipitation. In some cases, the precipitation may evaporate
before reaching the ground, a phenomenon known as virga.
