...MEDFORD OREGON WEATHER REVIEW: SEPTEMBER 2017...

The hot, dry and very smoky conditions from the end of August
continued into the first week of September 2017. Low visibilities and
very unhealthy air quality due to thick smoke from area wildfires
continued to affect the Rogue Valley during this first week.
Afterwards, moisture and energy associated with the remnants of
Hurricane Lidia drifted into the forecast area bringing another
round of thunderstorms. Fortunately, given the tropical nature of
the moisture, these thunderstorms also produced wetting rains.
Medford saw its share of moisture from these thunderstorms as one
moved through during the late morning on the 7th. Many of the
wildfires received beneficial rainfall from the thunderstorms and
these rains helped to dampen fire activity and improved air quality.
Smoke and low visibilities briefly returned the storms moved through.

By the middle of the month, the first Fall-like system of the season
brought much welcomed relief from warm temperatures and dry
conditions. Medford saw a little more than half of the month`s total
precipitation during this system. Temperatures were as low as 10 to
15 degrees below normal and low maximum temperature records were
challenged. Crater Lake and similar elevations received the first
snowfall of the season during this system.

Once this system finally pushed east of the area, temperatures
warmed as high pressure resumed control. During the last few days of
the month, another low pressure system moved over the area. This
system was much drier than the mid-month system and Medford only
recorded a trace of precipitation, while locations north and along
the coast measured up to a quarter of an inch.

The average temperature for the month was 67.5 degrees, which is 0.7
degrees above normal. The average maximum temperature was 81.5
degrees, which is 2.0 degrees below normal. The average minimum
temperature was 53.5 degrees which is 3.5 degrees above normal. The
highest temperature for the month was 105 degrees on the 1st. The
lowest temperature for the month was 39 degrees which occurred on
the 22nd.

There were 15 clear days, 7 partly cloudy days, and 8 cloudy days.

Total precipitation for the month was 0.30 inches, which is 0.27
inches below normal. The total precipitation for the water year
(beginning October 1st) stands at 25.21 inches which is 6.86 inches
above normal. Calendar Year precipitation is now 13.52 inches which
is 2.81 inches above normal.

The average wind speed for the month was 3.1 mph. The fastest
recorded two-minute wind was 23 mph from the southwest on the 7th
and again on the 20th. The peak wind was 31 mph from the
southwest which occurred on the 7th.

The highest pressure for the month was 30.19 inches on the 10th. The
lowest pressure for the month was 29.72 inches on the 13th.
