PLEASANTLY WARM AND DRY TODAY UNDER SUNNY SKIES….
After the cloudy and chilly weekend, today has returned to
the pleasant weather we’ve become accustomed to for much of
this month. Plenty of sunshine and temperatures into the
mid-upper 70s is the theme across the region this afternoon.
To add to the comfort, the dew point has dipped into the mid
40s, making it just a splendid day.
The wind has been a little busy today with mainly a northerly
breeze averaging around 10mph. However gusts to 25-30mph are
occurring making for breezy conditions.
Visibility has been excellent all day averaging around 70
miles!
The high so far today is 75F, which is 2 degrees below
the normal maximum of 77F. The low since midnight is 48F,
which is 11 degrees below the normal minimum of 59F.
