HOT AND HUMID UNDER A MIX OF SUN AND CLOUDS; ANOTHER 90F DEGREE DAY….
Hot and humid conditions are the theme today with our 9th 90F
degree day of the season occurring. The high through 1 P.M. is
90.2F. With the dew point hanging out in the mid 60s all day, it
has been rather humid feeling, just adding to the discomfort of
the day.
The one saving grace, if you want to call it that, is the wind.
A breeze gusting between 25-30mph has been blowing out of a west-
southwesterly direction allowing for nice ventilation. The average
speed for the day thus far is around 11mph.
Visibility has been limited to around 35 miles today due to
general haziness.
The high so far today is 90F, which is 8 degrees above the
normal maximum of 82F. The low since midnight is 66F, which
is 2 degrees above the normal minimum of 64F.
The yearly rain deficit has now reached 9.59″ below normal!
Most of the area is under a severe drought.
With only 0.80″ of rain for the month of July, the month ended
up 4th on the lowest July Precipitation list.
BHO Lowest July Precipitation, inches (1885-2022):
1. 0.13 in 1953
2. 0.33 in 1957
3. 0.72 in 1968
4. 0.80 in 2022
5. 0.85 in 1917
6. 0.87 in 1937
7. 0.92 in 1965
8. 1.08 in 1939
9. 1.11 in 1983
10. 1.13 in 1970
Interestingly, the average maximum of 86.6F for the month was only
2nd highest on record and the average minimum of 65.7F was only
4th warmest.
However the 24-hour adjusted mean temperature of 75.3F was not
only the warmest July on record, but warmest month on record.
BHO Warmest July 24-Hour Adjusted Mean Temperature, deg F (1885-2022):
1. 75.3 in 2022
2. 75.1 in 2010
3. 74.9 in 1952
4. 74.5 in 2019
5. 74.1 in 1994
