OVERCAST SKIES AFTER OVERNIGHT LIGHT RAIN, CONTINUED MILD….

Clouds have been the theme today with overcast skies
dominating so far. Fog this morning held visibility below
1/4 mile, but has since lifted early this afternoon.
Rain fell in the wee hours of this morning depositing
0.11″ in the rain gauge. An area of drizzle passed through
between noon and 1pm leaving only a trace.

The temperature has been slowly pushing toward 60F after a
morning low of a balmy 54F. The dew point has also been
creeping up in lock step with the temperature, as such it
feels rather humid out there. Certainly not what one would
expect on November 1st!

The wind has been quite light all day out of a southwest to
west-southwesterly direction. The average speed for the day
so far is only around 9mph.

As mentioned, visibility has been limited today. Holding below
1/4 mile this morning in fog, but has improved to around 20
miles early this afternoon as the fog lifts.

The high so far today is 60F, which is 5 degrees above
the normal maximum of 55F. The low since midnight is 54F,
which is 16 degrees above the normal low of 38F.
