VERY PLEASANT DAY WITH PLENTY OF SUNSHINE AND COMFORTABLE

Today has featured plenty of sunshine with a drier air mass and
very pleasant temperatures. Definitely a very fine late spring

Temperatures are near seasonable levels with readings in the mid

with readings dropping from the low 50s to the upper 40s.

Winds were a bit gusty overnight, but dropped off early this

It started out of a northerly direction, but became a bit of a
sea-breeze by early this afternoon. The average speed for the
day so far is around 8mph. The peak gust of 20mph occurred at
midnight.

Visibility has been excellent all day with the view around 70
miles all day.

The maximum temperature so far today is 76F degrees, which is
3 degrees above the normal high of 73F. The minimum temperature
