ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0628E

MAINLY OVERCAST TODAY WITH A FEW VERY LIGHT RAIN SHOWERS THIS
MORNING….
The day started on the dry side, but with mainly cloudy skies.
A few very light rain showers developed between 9-10am and have
continued off and on into early this afternoon. The rain has been
very light, and thus has only amounted to a trace.
Temperatures are once again near seasonable norms for today, at
least in terms of daytime readings which have reached the mid 50s.
The overnight low was still considerably above normal in the mid
40s. Normal lows should be in the mid 30s. Dew points have slowly
risen from the mid 30s early this morning to the mid 40s by early
this afternoon. This rise is mostly due to the light precipitation
moving through the area.
Winds have been pretty steady, but not as strong as yesterday.
They have mostly been out of a westerly direction, averaging at
around 12mph for the day so far. The peak gust for the day so far
is 28mph, which occurred just before 12:45pm this afternoon.
Visibility has been decent for the most part, generally between
50-60 miles throughout the day. It has dropped a bit lower at
times due to the rain, but such occurrences have been brief.
The maximum temperature so far today is 56F, which is 4 degrees
above the normal high of 52F. The minimum temperature since
midnight is 45F, which is 9 degrees above the normal low of 36F.
