...MEDFORD OREGON WEATHER REVIEW: SEPTEMBER 2022...

September began hot with the first 11 days of the month averaging
above normal, including 4 days where the high temperature was in
excess of 100F. One of these days, the 6th, set a record for the
date when it reached 107F, eclipsing the record of 104F set in 1923.
Wildfire smoke from the Rum Creek wildfire in Josephine County as
well as the Mountain/Mill fires in Siskiyou County produced several
days of diminished air quality. Thunderstorms occurred on the 7th,
which brought little precipitation, but also a smattering of cloud
to ground lightning -- about 210 flashes. Most of these occurred in
Klamath and Lake counties, though 16 were recorded locally in
Jackson County and around Medford. The first real stretch of
cooler weather arrived on the 13th and continued through the 23rd.
During the stretch, most days averaged right around normal with
respect to temperature, but the 17th was cooler -- 10F below
average. Showers were common area wide from the 17th to the 21st.
Thunderstorms on the 17th brought another significant round of
lightning with 270 flashes, mostly focused from the Shasta Valley up
along and just east of the Cascades. But, these were wet storms and
resulted in little new fire activity. In fact, from the 19th-21st,
low pressure drenched the area resulting in a widespread wetting
rainfall with some areas receiving 0.50-1.00 inch of rain. Medford
set a daily precipitation record on the 20th with 0.43 inches of
rain. The previous record was 0.22 inches set in 1984. With
all the rainfall, most area fires were doused, but one burning
in Lane County to the north, the Cedar Creek fire, continued to
bring smoke at times into northern sections of the forecast area.
Despite the true change of seasons to autumn, "summer" returned at
the end of the month, with 4 consecutive days of 90F or better at
Medford airport from the 24th-27th. No additional records were set
though.

The average temperature for the month was 71.3 degrees, which is
3.6 degrees above normal. The average maximum temperature was
87.1 degrees, which is 2.8 degrees above normal. The average
minimum temperature was 55.6 degrees, which is 4.4 degrees above
normal. The highest temperature for the month was 107 degrees
which occurred on the 6th. The lowest temperature for the month
was 46 degrees which occurred on the 30th.

There were 20 clear days, 10 partly cloudy days, and 0 cloudy
days.

Total precipitation for the month was 0.52 inches which is 0.04
inches above normal. Total precipitation for the water year
(beginning October 1st) was 15.75 inches which is 2.68 inches below
normal. Calendar year precipitation is 7.84 inches which is 3.23
inches below normal.

The average wind speed for the month was 3.6 mph. The fastest
recorded two-minute wind speed was 22 mph from the northwest which
occurred on the 2nd. The peak wind was 30 mph from the northwest
which occurred on the 2nd.

The highest pressure for the month was 30.22 inches on the 29th.
The lowest pressure for the month was 29.52 inches on the 9th.
