HOT AND HUMID WITH LIMITED VISIBILITY FOLLOWING
UNDERWHELMING RAINFALL FOR THE SUMMIT….
Today was hot again with partly cloudy skies and a limited
visibility of only 35 miles due to haze. Wind was southwesterly,
reaching 25 mph for the max gust later on in the day.
Conditions were hot and humid with dew points staying in the
low 70’s as temperatures made their way into the mid 90’s.
Despite heavier localized rainfall in areas to our north,
west, and south, we only received a very underwhelming
0.01 inches from last night’s convection-induced rain.
The high so far today is 95F, which is 13 degrees above the
normal maximum of 82F. This matches the record, set
in 1931.
The low since midnight is 72F, which is 8 degrees above the
normal minimum of 64F.
The yearly rain deficit has now reached 10.11″ below normal!
Most of the area is under a severe drought.
