INCREASING CLOUDS WITH A FRESHENING ONSHORE WIND AS A STORM
SYSTEM APPROACHES THE REGION….
A brief sliver of sunshine early this morning was quickly over-
taken by increasing cloud cover ahead of a storm system that
has moved from the Ohio Valley to the New Jersey coast. It’s
been dry so far today, albeit on the cool side. It has still
been a decent day for outdoor activities despite the lack of
sunshine.
Temperatures started the day in the low 40s and only rebounded
to the low 50s by early this afternoon. This is pretty much
at normal levels for the date in terms of the day-time readings.
Dew points have slowly edged upward from the upper 30s to the mid
40s as the onshore flow took hold.
Winds were generally light through the morning out of a south-
easterly direction. It has since picked up a bit early this
afternoon out of more of an easterly direction. The average
speed for the day so far is around 7mph, but again the trend
has been increasing the past hour or two. The peak gust for the
day so far is 18mph, which occurred just after 2:30pm this
afternoon.
Visibility has been somewhat limited today due to haziness or
thin fog. The view has generally been between 30-40 miles all
day.
The maximum temperature so far today is 51F, which is equal to
the normal high. The minimum temperature since midnight is 45F,
which is 10 degrees above the normal low of 35F.
