MILDER WITH ENJOYABLE WEATHER AND A COOL
WESTERLY BREEZE….
We observed a visibility of 40 miles today, due to
a layer of haze in the distance.
Today was on the milder side with temperatures climbing
into the low 70’s, but dew points hung around in the mid
40’s. This made weather conditions very comfortable.
Today marks a return to a monthly rainfall deficit, and the
annual deficit approaches 11 inches yet again. Drought monitor
is updated tomorrow.
Wind is westerly at around 15 mph, with frequent gusts above
20 mph following noontime. Wind was on the lighter side
earlier on in the day.
The low since midnight is 45F, a degree below the normal low.
The high so far today is 65F, which is 2 degrees above the
normal maximum of 63F.
